  Yield Traits of High-quality and High-yield Conventional Indica Glutinous Rice ‘Zhenzhunuo’ QUAN Ruilan, FU Ding, MA Hanyun, HUO Erwei, SHEN Guanghui, GUO Guiying, WANG Qinglin 2022, 12 (2):  1-7.  DOI: 10.11923/j.issn.2095-4050.cjas2020-0005 Abstract + ( 463 )   HTML ( 6 )   PDF ( 1232KB )   ( 227 ) To further explore the yield potential of the high-quality and high-yield indica glutinous rice variety ‘Zhenzhunuo’ and improve planting efficiency, the rice comparison test data of Xinyang City Academy of Agricultural Sciences in recent years were used in this study. The correlation analysis, regression analysis and path analysis were carried out to analyze the whole growth period (x1), plant height (x2), effective panicle (x3), ear length (x4), grain number per ear (x5), seed setting rate (x6), thousand-grain weight (x7) and yield (y). The results showed that the variation coefficient of agronomic traits of ‘Zhenzhunuo’ was expressed as follows: grain number per ear>effective panicle>ear length>seed setting rate>yield>thousand-grain weight>plant height>whole growth period, and the coefficient ranged from 5.27% to 19.74%. The correlation analysis, path analysis and regression analysis results showed that the agronomic traits of effective panicle, grain number per ear and seed setting rate had the greatest effect on the yield of ‘Zhenzhunuo’, and their correlation coefficient, partial correlation coefficient and direct path coefficient with yield reached extremely significant (P<0.01) or significant (P<0.05) level. The comprehensive decisive effect on yield was as follows: grain number per ear>seed setting rate>effective panicle. Through stepwise regression analysis, the agronomic traits of effective panicle, grain number per ear and seed setting rate significantly affecting the yield of ‘Zhenzhunuo’ were screened out to establish the optimal regression equation: y=1729.381+8.859x3+7.743x5+37.755x6. Therefore we must take measures to increase the effective panicle, grain number per ear and seed setting rate, which are the main agronomic traits affecting the yield of ‘Zhenzhunuo’, to promote the variety’s application and achieve high yield.

The results showed that: (1) the average value of soil pH, organic matter, alkaline hydrolysis N, available P, available K, total N, total P and total K in the survey fields was 4.77, 20.35 g/kg, 25.12 mg/kg, 17.33 mg/kg, 136.91 mg/kg, 1.19 g/kg, 0.54 g/kg and 16.30 g/kg, respectively; (2) the soil was acidic and the nutrients’ contents were at the medium and lower level in the survey fields, and the insufficient ratio of each nutrient index was 35.39% (available K) to 100% (alkaline hydrolysis N); (3) correlation analysis indicated that only available K had significantly negative effect on the root dry weight per plant of Pueraria thomsonii Benth, and the other nutrients had no significantly different effect on the root dry weight. It is suggested that we should adopt balanced fertilization, reduce the amount of chemical fertilizer and apply organic fertilizer with inorganic fertilizer to improve the soil nutrient status, and use alkaline fertilizer or lime to improve the acid soil and enhance the fertility of Pueraria thomsonii Benth fields.

  Meteorological Factors on Freezing Injury of Amygdalus communis During Overwintering in Yingjisha of Xinjiang Kerimu ABASI, Nuerpatiman MAIMAITIREYIM, MENG Fanxue, CHEN Gang, Patiman ABUDUAINI 2022, 12 (2):  31-35.  DOI: 10.11923/j.issn.2095-4050.cjas20191100279 Abstract + ( 2062 )   HTML ( 732 )   PDF ( 1186KB )   ( 10114 ) By using the basic meteorological data of 2001 to 2019 from Yingjisha national meteorological observing station and the phenological observation data and freezing injury data, the freezing rate of flower bud and yield of Amygdalus communis were analyzed. Combined with mathematical statistics, the meteorological factors causing frozen flower bud during overwintering period of Amygdalus communis in Yingjisha were studied. The results showed that the lowest air temperature in winter and its lasting days, the lowest land surface temperature and frozen earth depth caused the freezing of Amygdalus communis buds, but there was no obvious impact of the maximum snow depth of winter and its lasting days and winter precipitation. When the lowest temperature was -23℃ to -18℃, its lasting days and the lowest land surface temperature were the main factors causing frozen flower buds.

  Color Change of Flue-cured Tobacco During Short-term Storage ZHANG Ting, WANG Hongyi, LIAO Xiaoling, LIU Jun, XIAO Shaohong, CHEN Hui, WANG Kang 2022, 12 (2):  36-39.  DOI: 10.11923/j.issn.2095-4050.cjas2020-0177 Abstract + ( 297 )   HTML ( 1 )   PDF ( 1084KB )   ( 260 ) To study the color difference of main flue-cured tobacco varieties in Hubei Province and their color changes during short-term storage for 150 days, the color values of ‘Yunyan 87’, ‘K326’ and ‘Jinshennong No.1’ were measured, including brightness L*, redness a*, yellowness b*, and saturation C*. The results showed that the color difference of the three varieties’ leaves reached a very significant level, among which, ‘Yunyan 87’ had high color brightness, yellowness and saturation, ‘Jinshennong No.1’ had relatively high color redness, yellowness and saturation, ‘K326’ had middle color brightness and redness, and relatively low yellowness and saturation. The color uniformity of ‘Yunyan 87’, ‘K326’ and ‘Jinshennong No.1’ decreased in turn. During the short-term storage of 150 days, the color brightness, yellowness and saturation of the three varieties increased gradually, but the redness gradually decreased. With the extension of the storage time, the color difference of the three varieties increased gradually compared with the early stage after curing. The biggest color difference was found in ‘Jinshennong No.1’, followed by that of ‘Yunyan 87’, and then ‘K326’. Therefore, ‘K326’ is the most stable color variety in short-term storage, followed by ‘Yunyan 87’, and ‘Jinshennong No.1’ is most likely to change color with the storage time.

  Identification of Pod Shattering Resistance of Early-maturing Brassica napus L. and Material Screening TIAN Zhengshu, LUO Yanqing, CHI Xuchun, ZHAO Kaiqin, ZHANG Yunyun, FU Minglian, LI Jinfeng 2022, 12 (2):  40-46.  DOI: 10.11923/j.issn.2095-4050.cjas2020-0008 Abstract + ( 336 )   HTML ( 2 )   PDF ( 1357KB )   ( 273 ) To screen pod shattering resistant varieties and to promote the mechanized production process of rapeseed (Brassica napus L.) in areas of early-maturing varieties, pod shattering resistance index (SRI) of 98 early-maturing Brassica napus L. materials was assessed with random impact test method. The testing results were analyzed by cluster analysis and correlation analysis in combining with related agronomic traits. The results showed that the coefficient of variation (CV) of SRI was 41.38%, and the materials with SRI≥0.4 accounted for 68.4%. The cluster analysis demonstrated that the 98 early-maturing Brassica napus L. materials were clustered into three groups: A, B, and C. The average SRI of group A was 0.35, presenting easy shattering. The average SRI of group B was 0.93, presenting high resistance to shattering. The average SRI of group C was 0.65, presenting moderate resistance. The correlation analysis with main agronomic traits showed that SRI had an extremely and significantly positive correlation with pod length and a significantly positive correlation with 1000-seed weight, indicating that pod length and 1000-seed weight significantly affected pod shattering resistance, and both the two indexes could be used in shattering resistance screening of Brassica napus L.. Finally, the test materials with SRI>0.4 were screened in terms of yield and oil content, and 10 materials which had higher SRI and 5% more yield increase compared with that of CK (‘HY8’) were screened out. The study could provide theoretical guidance for phenotypic identification, genetic analysis and molecular marker-assisted selection of pod shattering resistance in early-maturing Brassica napus L..

  Analysis of the Canopy Lines and Color of Landscape Plant Communities Based on Dimension Characteristics DUAN Chuanhong, ZHANG Jingli, WANG Xiaoyun, YAN Yan, HU Jie, RUN Jing 2022, 12 (2):  60-64.  DOI: 10.11923/j.issn.2095-4050.cjas2020-0178 Abstract + ( 293 )   HTML ( 3 )   PDF ( 1687KB )   ( 303 ) To improve the level of planting arrangements, the landscape was quantitatively analyzed from canopy lines and color of plant communities. 3 residential green spaces were selected to measure the fractal dimension of canopy lines and the information dimension of color. The study revealed that the variation in fractal dimension of canopy lines was large within the same group and the variation was small between different groups in the sample communities. The community landscape formed by the combination of garden buildings and plants had high fractal dimension, and canopy lines entirely formed by plant landscape were continuous and had more natural charm. The variation of the canopy contour at different levels within the community was of great fractal dimension, while the canopy lines with discontinuity and mainly based on buildings had low landscape fractal dimension. The information dimension of color reflected the complexity and non-uniformity of color distribution, and the relatively high dimension was one of the characteristics of garden plant community close to the natural community. The comparison and analysis of the 3 sample communities indicated that the plant species were relatively similar, and the planting arrangements in the samples were monotonous. Therefore, it is suggested to strengthen the development of local plant resources and plant configuration level, so as to build near-natural artificial plant communities.

  The Distribution Characteristics and Influencing Factors of Agriculture-related Leading Enterprises in Shanxi Province Under the Background of Rural Revitalization WANG Ruoyu, ZHAO Min 2022, 12 (2):  92-100.  DOI: 10.11923/j.issn.2095-4050.cjas2021-0179 Abstract + ( 300 )   HTML ( 4 )   PDF ( 1437KB )   ( 419 ) The analysis of the spatial distribution of agriculture-related leading enterprise has guiding significance for understanding the regional modern agricultural development level. The study took agricultural-related leading enterprises in Shanxi Province as the research objects, used geographic analysis methods such as kernel density estimation and local hotspot analysis to study their spatial distribution and aggregation characteristics, and used multiple regression analysis to determine the factors which would affect the distribution of agriculture-related leading enterprises. The results show that the agricultural-related leading enterprises in Shanxi Province gather in the central of the province and form obvious hot spots in the junction of Taiyuan, Jinzhong and Lvliang, while the cold spots are scattered in the northwest of Taiyuan and the middle part of Xinzhou. In terms of influencing factors, the total mileage of highway, agricultural machinery total power and the total retail sales of social consumer goods show clear positive effects on the layout of the leading enterprises, while urbanization rate is negatively correlated with the layout. According to the above analysis results, the study puts forward suggestions such as giving full play to the radiation effect of the leading enterprises in hot spots, upgrading provincial transportation facilities, improving agricultural production conditions, building regional famous brands and addressing the problem of rural population loss.
