The results showed that ‘Heixiang DL-1’ had the best content of functional elements, ‘Daliangnuo No.1’ had relatively high content of protein and iron, and higher content of selenium than that of common varieties. ‘Crystal No.1’ could be planted as iron rich variety, ‘Crystal No.2’ and ‘Yueguang’ could be planted as zinc rich variety, and ‘Changlixiang’ could be developed as selenium rich variety.

  Effect of Several Biological Agents on Controlling Rice Blast and Improving Yield and Quality of Organic Rice YAN Yu, WANG Weijian, YAO Yutian, CHEN Chen, QIU Jun, ZHANG Xiaowei, CHEN Xijun 2022, 12 (7):  5-11.  DOI: 10.11923/j.issn.2095-4050.cjas2021-0059 Abstract + ( 269 )   HTML ( 11 )   PDF ( 1251KB )   ( 202 ) Rice blast is one of the most serious diseases in organic rice production. To clarify the effect of several biological agents on controlling rice blast and improving yield and quality of organic rice, the disease severity, defense enzyme activities, and yield and quality indexes were detected after seed treatment and foliage spraying using the biological agents. Results showed that the biological agents used for seed soaking combined with foliage spraying had high control effects on rice blast, and the control effect of Bacillus subtilis, shenqinmycin and kasugamycin on leaf-blast was 62.84%, 58.11% and 54.05% respectively, and the disease index control efficacy was 81.07%, 56.49% and 46.11% respectively, the control effect on panicle-blast was relatively poor, 63.63%, 54.62% and 54.05% respectively, and the disease index control efficacy was 48.92%, 34.23% and 29.85%, respectively. After treatment with biological agents, the activities of defensive enzymes in rice plants were significantly increased, and most of them reached the maximum within 1-7 days. Yield-related indexes such as grain number per panicle, seed setting rate and 1000-grain weight increased significantly while the rate of brown rice, milled rice and head milled rice increased slightly. The content of amylose and protein increased slightly while the rate of chalky and green rice decreased significantly. The results indicated that application of biological agents could effectively control rice blast and improve the yield and quality of organic rice.

  Analysis on the Cause of ‘Stay Green’ of Summer Soybean in Southwest Shandong Province ZUO Xiufeng, JIAO Yuxia, CAO Zeng, ZHAO Yanli, ZHU Qingrong, WANG Xianghui, HU Yinghua 2022, 12 (7):  12-16.  DOI: 10.11923/j.issn.2095-4050.cjas2022-0036 Abstract + ( 363 )   HTML ( 10 )   PDF ( 1248KB )   ( 178 ) The summer soybean ‘stay green’ occurs occasionally in southwest Shandong in recent years, and it causes serious loss in some years. To explore the potential reasons of this phenomenon, the study conducted two experiments to illustrate the effects of temperature and Riptortus pedestris on summer soybean ‘stay green’ in two counties of Jining City. The experiments of different sowing dates of the same soybean variety and different treatments of the same soybean variety at the same sowing date were carried out to explore the effects. Different soybean varieties all had a relatively good yield with different sowing dates in 2019-2020; while under different treatments of the same variety at the same sowing date, except the difference of the yield, there was no any large scale of ‘stay green’, and the rate of the phenomenon was below 2%. Preliminary result demonstrated that the outbreak of soybean ‘stay green’ in 2018 in southwest Shandong Province was related to the high temperature in flowering and podding stage, which had nothing to do with Riptortus pedestris. It is suggested that farmers should postpone the sowing date of summer soybean and strengthen the field management, which are important to the production of soybean.

  Rape Clubroot in Anning: Biocontrol Techniques PAN Wenzheng, WANG Bin, ZHANG Qi, MAO Minglin, LI Cheng, ZI Wenlin 2022, 12 (7):  17-20.  DOI: 10.11923/j.issn.2095-4050.cjas2020-0253 Abstract + ( 251 )   HTML ( 5 )   PDF ( 1172KB )   ( 166 ) The aims are to explore the new biological control model of rape clubroot in Anning, and to study the effect of biocontrol strains on rape clubroot. The research is carried out through a plot test with direct application of the biocontrol functional strains, and adding the biocontrol functional strains to organic fertilizer or substrate application. The results showed that: the biocontrol functional strains could effectively reduce the occurrence and damage of rape clubroot. The control effect was 74.03% on rape clubroot when biocontrol functional strains were directly applied, 83.12% when the strains were added to organic fertilizer, 68.83% when the strains were added to substrate, and 89.61% when the chemical control was used. Adding biocontrol strains to organic fertilizer which was decomposed and fermented from rape straw could achieve the best control effect on rape clubroot, and promote the growth and development and the yield of rape. Compared with conventional fertilization, the plant height, the effective branch number and the yield were increased by 7.63%, 26.08% and 16.81%, respectively.

  Control of Postharvest Anthracnose of Mango Fruits by Luna Sensation and Nativo YE Zi, SU Chulian, SUN Yu, LIU Xiaomei, PU Jinji, ZHANG He, HUANG Hai 2022, 12 (7):  21-25.  DOI: 10.11923/j.issn.2095-4050.cjas2020-0239 Abstract + ( 738 )   HTML ( 7 )   PDF ( 1275KB )   ( 499 ) In order to explore the methods of controlling postharvest anthracnose by using fungicide in mango flowering and fruiting stage, Luna Sensation and Nativo fungicides were selected to carry out the experiment of postharvest anthracnose control. A total of 6 treatments were designed, including two application dose gradients of each fungicide, a prochloraz test area and a blank test, to compare the disease index among the treatments. The results showed that the fungicides used in this experiment did not harm the young leaves, flowers and young fruits of mango at flowering and fruiting stage, nor did they affect the ripening of mango. 7 days after harvest, the control effect of Luna Sensation sprayed with 1500 times of concentration was equivalent to that of prochloraz, and the control efficiency reached 72.73%, the shelf life could be maintained for 7 days. The control effect of Nativo sprayed with 750 times of concentration was the second, its control of mango anthracnose during the postharvest storage period was effective, and the shelf life and storage period of mango were prolonged obviously. The presence of a new succinate dehydrogenase inhibitor in Luna Sensation, named fluopyram, could work by inhibiting the activity of succinate dehydrogenase. Succinate dehydrogenase inhibitors impede the mitochondrial function by interfering with four subunits of complex II, inhibiting the production of energy and the growth of pathogenic bacteria. The fungicides in this study are consistent with prochloraz in treatment and have a certain value of popularization and application.

The bacterium was identified through physiological and biochemical analysis and sequence alignment of 16S rRNA, gyrA and gyrB genes. Meanwhile, its bio-control effects were evaluated by antimicrobial activity, pot and field control efficiency test. Results show that the bio-control bacterium JM-3 is Bacillus velezensis, and its inhibition rate of plate confrontation to Fusarium oxysporum f. sp. Fragariae is 57.42%. Pot experiment shows that, 90 d after treatment, the control effect of bio-control bacterium JM-3 solid preparation on disease index of strawberry Fusarium wilt is 83.02%, higher than that of liquid preparation and carbendazim treatment, indicating the higher persistence of solid preparation. The result trend of field experiment is basically consistent with that of pot experiment. Sugar-acid ratio of strawberry fruit treated with liquid and solid preparation of bio-control bacterium JM-3 is 8.88 and 8.90 respectively, significantly higher than that of carbendazim treatment and CK. The experiment indicates that antagonistic bacterium JM-3 has excellent bio-control effect on strawberry Fusarium wilt, is helpful to improve strawberry fruit quality, and exhibits a good application prospect.

  Improvement Effect of Combined Application of Phosphogypsum and Limestone Powder on Newly Cultivated Red Soil YAN Jianli, ZHANG Mingkui, WANG Daoze 2022, 12 (7):  33-37.  DOI: 10.11923/j.issn.2095-4050.cjas20200300063 Abstract + ( 255 )   HTML ( 8 )   PDF ( 1104KB )   ( 209 ) Newly cultivated red soil has many defects, such as strong acid and poor nutrient content, and needs to be improved by many measures. To understand the effect of phosphogypsum and limestone powder on reducing acidity and increasing mineral nutrients in the newly cultivated red soil, a pot experiment was designed to study the effect of applying different amounts and combinations of phosphogypsum and limestone powder on soil acidity, available nutrients and crop growth. The results showed that both phosphogypsum and limestone powder could significantly reduce soil acidity and increase soil available calcium, and the effect increased with the increasing dosage of amendments. Under the condition of equal mass application of the amendments, the effect of the single application of limestone powder or the combined application of phosphogypsum and limestone powder on the reduction of soil acidity was higher than that of the single application of phosphogypsum. The effects of the combined application of phosphogypsum and limestone powder or single application of phosphogypsum on the improvement of soil mineral nutrients, physical properties and vegetable growth were higher than those of single application of limestone powder. Under the experimental condition, the application of phosphogypsum did not significantly increase the accumulation of heavy metals in the soil, and the content of Cd, Cr and Pb in vegetables decreased due to the increase of soil pH, but the content of As increased slightly, which had no obvious effect on the accumulation of other heavy metals in vegetables. The results showed that the newly cultivated red soil with obvious acidification and low nutrients could be improved by the combined application of phosphogypsum and limestone powder instead of limestone powder alone, but the application amount of phosphogypsum should be controlled properly.

  Research on the Relationship Between the Meteorological Factors and the Breeding of Shrimp and Crab in Xiangyang, Hubei LIU Xianghe, KONG Jianghong 2022, 12 (7):  74-80.  DOI: 10.11923/j.issn.2095-4050.cjas20200300077 Abstract + ( 334 )   HTML ( 11 )   PDF ( 1256KB )   ( 272 ) This paper aims to evaluate the influence of meteorological factors on the shrimp and crab breeding industry in Xiangyang of Hubei Province, and put forward corresponding measures for scientific breeding of shrimp and crab. The laws of meteorological factors' change were analyzed based on nearly 30 years data observed in Xiangyang. The authors reviewed the annual changing trend of main meteorological factors related to the breeding of shrimp and crab, such as temperature, sunshine hours, continuous wet weather, rainstorm, wind force and atmospheric pressure, and discussed the potential climate risks, in order to make rational use of weather forecasting and early warning to achieve the purpose of disaster prevention and reduction. The results showed that suitable temperature, abundant rainfall, mild climate, sufficient sunshine and relatively fewer meteorological disasters could provide favorable climatic conditions for the breeding of shrimp and crab in Xiangyang. By analyzing the law of temperature change in Xiangyang and the relationship between air temperature and water temperature, the authors determined the best period of postlarvae release (after Qingming) and the best period of fishing (before Frost's Descent) for shrimp and crab breeding. At the same time, the authors also analyzed the effects of meteorological factors such as low temperature damage, sunshine hours, continuous rainstorm, gale and thunderstorms on the breeding of shrimp and crab, and put forward the corresponding preventive measures to reduce the impact of weather disasters. This study could provide a theoretical basis for the local meteorological department to make medium and long-term climate prediction and short-term weather forecasting and warning services according to the shrimp and crab breeding cycle. Based on our research results, farmers should attach great importance to the application of early warning information and take active measures to reduce the loss of shrimp and crab breeding caused by meteorological disasters.
