Study on Net Soybean Cropping Screening Based on Agronomic Traits and Yield Indicators
The article took eight local soybean resources and four introduced soybean varieties in Bazhong region as the research objects,conducted a comparative experiment on their agronomic traits and yield indicators of net crop varieties,and selected suitable soybean varieties for planting in Bazhong region.The results showed that the appearance quality,100-grain weight and yield of introduced soybean varieties were superior to local soybean varieties.Local soybean in Bazhong area had short growth period,small 100-grain weight,large effective pod grain ratio and low yield,introduced soybean varieties had long growth period,full particles,big 100-grain weight and high yield.Among the local soybeans varieties,the comprehensive performance of 220302 was good,the effective pod grain ratio was 0.61,100-grain weight was 19.6 g,and the yield was 1 818.00 kg/ha.Among the 12 soybean materials,introduced soybean varieties Qihuang 34 showed good comprehensive performance,with an effective pod ratio of 0.45,100-grains weight was 24.23 g,and the yield was 2 034.75 kg/ha,which was suitable for promoting the planting of early maturing soybeans as a substitute for local soybean varieties in Bazhong area.
