The results showed that, among the 67 germplasm resources, 27 germplasm resources contained the homozygous gene Pita (40.3% of the total number), 22 germplasm resources contained the homozygous gene pik (32.9% of the total number) and 12 germplasm resources contained both of the two homozygous genes (17.9% of the total number). Based on the results, the functional markers Pita-G/T and Pik2-C/T could be efficiently and accurately used in rice genotyping in Heilongjiang, meanwhile, through genotyping the materials in this research, we clarified the distribution of those two genes in Heilongjiang, which provided a theoretical basis for rice blast resistance breeding.

  Characteristics of Soil Organic Carbon Fractions of Main Agricultural Soils in Mid-subtropical Areas Yuan Hong, Li Han, Zhang Liang, Duan Liangxia, Huang Yunxiang, Wang Hui 2021, 11 (1):  17-21.  DOI: 10.11923/j.issn.2095-4050.cjas20190800173 Abstract + ( 506 )   HTML ( 6 )   PDF ( 1319KB )   ( 393 ) In main agricultural regions of mid-subtropical zone, to understand soil fertility status, the authors studied the content and accumulation characteristics of soil organic carbon components by field sampling and indoor analysis. The results showed that: the content of organic carbon (SOC) in purple soil was the highest, while the red soil had low organic matter content and the fertility level was not high. The variation tendency of soil easily oxidized organic carbon (EOC) was consistent with SOC. Light fraction organic carbon (LFOC), coarse particulate organic carbon(CPOC), fine particulate organic carbon(FPOC) had the largest proportion in red soil, river tidal soil and rice soil, respectively, which were related to soil parent material and development age. Under different utilizing ways, the content of SOC in tea garden was the highest. The sequence of SOC was tea garden > corn field > rice-rape field > cotton field > vegetable garden. The value of EOC/SOC in tea garden was 36.85%, which indicated that the soil organic carbon was stable. The value of EOC/SOC of other agricultural soils changed a little, ranging from 22.48% to 25.52%, with an average value of 23.44%. LFOC and CPOC were more sensitive to land use change than SOC, and were significantly affected by SOC, CEC, NO3--N and NH4+-N (P<0.01).

  Soil Nutrient Changes in Field Vegetable Base in Tonghai from 2004 to 2015 Mu Chan, Huang Cuiju, Qian Rongqing, Li Hongyang, Yao Zhaobing, Yang Shaocong, Li Jiayou, Zhang Yanjun, Hu Xuanjiang 2021, 11 (1):  22-26.  DOI: 10.11923/j.issn.2095-4050.cjas20191000222 Abstract + ( 465 )   HTML ( 6 )   PDF ( 1269KB )   ( 303 ) To find out the changes of nutrient content of field vegetable base in Tonghai County from 2004 to 2015, and provide references for rational fertilization, a comparative analysis was conducted with field sampling and laboratory testing. The results showed that in 2015, the soil pH of Tonghai field vegetable base was 7.57, with an average organic matter content of 43.8 g/kg. The effective N average content was 170 mg/kg, the proportion of field>151 mg/kg was 67.5%; the average effective P of soil was 111.2 mg/kg, and the proportion of field>50 mg/kg was 92.4%; the average effective K of soil was 194 mg/kg, and the proportion of field >151 mg/kg was 54.7%; the average exchange Ca was 19238 mg/kg, and the proportion of field>5001 mg/kg was 97.9%; the average exchange Mg was 908 mg/kg, the proportion of field >150 mg/kg was 100%. Compared with those of 2004, pH increased by 0.13, organic matter increased by 15.8%, effective N increased by 20.1%, effective P increased by 66.6%, effective K decreased by 13.4%, exchange Ca increased by 186.2%, and exchange Mg increased by 16.1%. It indicated that the nutrient concentration of soil N, P, Ca and Mg in the cultivated layer of soil in Tonghai field vegetable bases was relatively high, while the content of K was relatively low. Therefore, it is necessary to control N and reduce P, and supplement K appropriately, to balance fertilization and strictly control the use of lime in vegetable fertilization.

  Coastal Saline Soil in Jiangsu: Desalting Technologies and Application Prospect Sun Licai, Cui Shiyou, Zhang Jiao, Zhai Caijiao 2021, 11 (1):  27-31.  DOI: 10.11923/j.issn.2095-4050.cjas20190500039 Abstract + ( 631 )   HTML ( 11 )   PDF ( 1110KB )   ( 596 ) Coastal beach is the main land reserve resource in Jiangsu Province, and the exploitation, utilization and protection of coastal saline soil have been highlighted by governments at all levels. In this paper, three major desalination technologies for coastal saline soil based on the concept of salt balance index were summarized, including leaching by rainwater and brackish water, reducing salt accumulation in root zone by preventing capillary rise of groundwater, and biological desalting technology. In the practice of beach desalting and soil improvement, Jiangsu Province has formed its own technical system of desalination of coastal beach with the integration of the three technologies, including amelioration of saline soil by fish farming in mudflat pond, paddy cultivation by irrigation of brackish water, dry farming with straw mulching, and afforestation under straw mulching. It is expected that these technologies will provide effective technical support for the development and utilization of coastal tidal flat resources in Jiangsu Province.

  Film of Different Thickness: Effect on Residual and Recovery of Waste Film and Selection Yu Xianfeng, Zhao Jijun, Ma Mingsheng 2021, 11 (1):  32-36.  DOI: 10.11923/j.issn.2095-4050.cjas20190800157 Abstract + ( 651 )   HTML ( 19 )   PDF ( 1056KB )   ( 662 ) The research on the residual and recovery of mulch film with different thickness was summarized based on the existing research literatures, and the selection of mulch film was discussed to provide references for the coordinated development of agricultural production and environmental protection. The results showed that residual of different thickness films varied from crop to crop, the thicker the mulch film, the lower the residual amount. After reaching a certain thickness, the difference of residual amount was not significant, but after a certain thickness, the residual amount increased due to the increase residual quality per unit area. The use of thick mulch film could effectively improve the film recyclability, but the difference of recovery rate was not significant after the film reached a certain thickness. Mechanized recycling was the trend in the future, in addition to film strength, the influence of film thickness should draw more attention. In agricultural production, the selection of thin or thick film was both inappropriate, the thickness recommended by most scholars was between 0.008 and 0.012 mm, the specific effect between the film cover and the ecological benefit should be considered.

  Plastic Film Mulching Hole-planting Patterns: Effect on Grain Filling Characteristics and Water Use Efficiency of Setaria italica and Panicum miliaceum L. Kernels Li Wanbin, Dai Lijun, Li Yongping 2021, 11 (1):  37-43.  DOI: 10.11923/j.issn.2095-4050.cjas2020-0111 Abstract + ( 479 )   HTML ( 5 )   PDF ( 1370KB )   ( 391 ) This paper aims to provide a theoretical basis for planting Setaria italica and Panicum miliaceum L. under plastic film mulching hole-planting patterns in the arid region of southern Ningxia through studying the growth characteristics, filling character and water use efficiency (WUE) of crops. In the study, five mulching hole-planting patterns were set up: water-permeable plastic-film mulch, traditional plastic-film mulch, degradable plastic-film mulch, only mulching of ridge with plastic film + hole-planting in furrow, and no covered hole-planting (CK). The method of field location test combined with laboratory analysis was adopted. The yield-increasing effects of different mulching hole-planting patterns on Setaria italica and Panicum miliaceum L. were ranked as follows: water-permeable plastic-film mulch> traditional plastic-film mulch > only mulching of ridge with plastic film + hole-planting in furrow > degradable plastic-film mulch > no covered hole-planting (CK). Compared with CK, the yield of mulching hole-planting pattern of Setaria italica and Panicum miliaceum L. was increased by 48.4%-66.5% and 53.9%-70.3%, respectively, and the WUE was increased by 58.1%-80.6% and 31.9%-55.9%, respectively, the filling rate of main spike was 0.89-1.01 g/d and 0.34-0.39 g/d, respectively, 41.3%-60.3% and 36.0%-56.0% higher than that of CK. Under the mulching hole-planting and CK, the time entering the active filling stage was about 24 d and 30 d after heading, respectively, the filling termination period was 6 d earlier than that of CK. In summary, the patterns of water-permeable plastic-film mulch and only mulching of ridge with plastic film+ hole-planting in furrow are more suitable for Setaria italica and Panicum miliaceum L. in the arid region of southern Ningxia. In the context of water deficit, paying attention to the management of water and fertilizer in jointing stage and filling stage is the key measure to achieve high yield.

  Dynamic Changes of Endogenous Hormones in Leaves of Phalaenopsis amabilis During Flower Forcing Process Ma Xiaohua, Liu Hongjian, Zhang Qingliang, Hu Qingdi, Qian Renjuan 2021, 11 (1):  57-61.  DOI: 10.11923/j.issn.2095-4050.cjas2020-0135 Abstract + ( 927 )   HTML ( 18 )   PDF ( 1237KB )   ( 1053 ) To study the dynamic changes of endogenous hormones of Phalaenopsis amabilis ‘Green Bear’ during the process of flower induction, the healthy and mature P. amabilis ‘Green Bear’ of 2 years was used as the test material to determine the contents of auxin (IAA), gibberellin (GA), abscisic acid (ABA) and zeatin riboside (ZR) at 0, 15, 30 and 45 days of the flower bud differentiation stage, the stalk period, the bud period and florescence. The results showed that during the flower bud differentiation period 15-45 d, IAA and GA decreased significantly, and reached the lowest value during the flower bud differentiation period at 45 d, IAA and GA rise rapidly during the stem picking period and reached the maximum at 95 d, which were higher than the IAA and GA content in other periods greatly, and then both decreased from 195 to 240 days during flowering period. ABA and ZR increased significantly at the flower bud differentiation period 15 d, and the ABA content decreased during the stemming period, while ZR did not change significantly, and then both increased in the budding stage and the flowering stage from 0 to 45 days, then reached the highest value at flowering stage 240 d, respectively, which were 3.2 times and 2.97 times as much as the content at flower bud differentiation stage 0 d. Therefore, it is concluded that the changes of endogenous hormones play a significant role in regulating the development of the floral organs and flower bud differentiation of P. amabilis ‘Green Bear’. Low concentrations of IAA, GA and high levels of ABA and ZR can promote the differentiation of the flower buds of P. amabilis ‘Green Bear’, while high concentrations of IAA, GA and ZR are conducive to the pedicel elongation of the P. amabilis ‘Green Bear’.

A field experiment was conducted on Citrus maxima ‘Guanxi miyou’, two dosages were sprayed in bagging and non-bagging treatments, and then the residue was determined by QuEChERS combining with HPLC-MS/MS. The results showed that the residual degradation dynamics of etoxazole and acetamiprid followed the first-order kinetic equation, the half-life (T1/2) of etoxazole was 5.30-5.47 d in the bagging treatment, and 4.34-4.54 d in the non-bagging. T1/2 of acetamiprid was 3.42-3.80 d in the bagging treatment, and 3.04-3.70 d in the non-bagging. T1/2 of etoxazole was a little longer in the bagging treatment, but the T1/2 of acetamiprid had no obvious difference between the bagging and non-bagging treatment. The residues of etoxazole and acetamiprid in Citrus maxima ‘Guanxi miyou’ were not detected on the 65th day after spraying.

  Multivariate Analysis of Major Components and Free Nicotine Content in Oral Tobacco Zhang Pingquan, Xu Aifei 2021, 11 (1):  67-70.  DOI: 10.11923/j.issn.2095-4050.cjas20190500020 Abstract + ( 752 )   HTML ( 13 )   PDF ( 1173KB )   ( 394 ) To investigate the effect of major components of oral tobacco on free nicotine content, 41 Moist Snuff oral smokeless tobacco products were investigated by the correlation analysis, regression analysis and path analysis. (1) The correlation analysis results showed that the pH value and nicotine content were positively correlated with free nicotine content and their correlation coefficient was at 1% significant level and 5% level respectively, while the water content had no significant correlation with free nicotine content. (2) The multivariate linear regression equation reached an extremely significant level, indicating that there was a strong correlation between the water content, pH value, nicotine content and free nicotine content. (3) The path analysis results showed that the degree of direct influence on the free nicotine content was in the order as the nicotine content > pH value> water content, the pH value and nicotine content were positively correlated with free nicotine content, while the water content was negatively correlated with free nicotine content. (4) The water content and nicotine content had large indirect effects on free nicotine content through pH value, and they had positive and negative effects on the free nicotine content respectively. (5) The pH value had a large indirect and negative effect on free nicotine through nicotine. So, the content of free nicotine could be increased by increasing the content of nicotine or increasing the pH value of oral smokeless tobacco products.

  Effect of Biological Activity of Boscalid on Sclerotinia sclerotiorum of Sunflower Zhang Haiyang, Li Haiyan, Meng Qinglin, He Chaoqun, Pan Wenhan, Xu Jingyu 2021, 11 (1):  71-74.  DOI: 10.11923/j.issn.2095-4050.cjas20191000226 Abstract + ( 626 )   HTML ( 13 )   PDF ( 1267KB )   ( 334 ) The aims are to clarify the effect of the new fungicide boscalid on the biological activity of Sclerotinia sclerotiorum, and provide a scientific basis for its promotion and application. In this research, we used the hyphae, spores and sclerotia as test samples. Bioassay method was used to confirm the effect of boscalid on mycelial growth, spore germination and sclerotia formation of Sclerotinia sclerotiorum. The results showed that the mycelial growth rate of Sclerotinia sclerotiorum treated with boscalid was inhibited; the EC50 was 0.2152 μg/mL. With the increase of germicide concentration, the mycelial growth of Sclerotinia sclerotiorum decreased significantly. When the concentration was 16.667μg/mL, the inhibition rate of sclerotia formation of Sclerotinia sclerotiorum reached 84.62%, and the inhibition rate of total dry weight of sclerotia formation of Sclerotinia sclerotiorum reached 61.07%. The result of spore germination test showed that the germination of ascospores was inhibited after being treated with boscalid, and the EC50 was 0.056 μg/mL. The inhibition rate of spore germ tube elongation reached 78.15% at the concentration of 0.267 μg/mL. The boscalid not only inhibits the mycelial growth of Sclerotinia sclerotiorum, but also reduces the invasion of ascospores, and prevents the germ cells formed by the germination of ascospores from infecting the plant tissues continuously, which effectively reduces the residual amount of sclerotia in field soil. It has a very broad prospect for the prevention and treatment of sunflower sclerotinia, and can be used as a rotation agent for controlling sunflower sclerotinia in field.

In this study, the high pressure sodium lamp and the LED lighting were selected for supplementary light test in a strawberry production base. The effects of different ways of light supplement on vegetative growth, chlorophyll content, yield and fruit sugar content of strawberry were observed. The results showed that the two ways of light supplement had effect on temperature increase in greenhouse, and the effect of high pressure sodium lamp was more obvious. There was no significant effect of the two light sources on strawberry plant height, leaf length and leaf width. Both light sources had significant effect on increasing the chlorophyll content of strawberry plants, which reached extremely significant level compared with the control. The soluble solid content of strawberry was higher than that of the control after light supplement with two light sources, and the effect was more significant with high pressure sodium lamp.
