以1994年分期播种试验资料,分析积温、累计日照时数、累计降雨量和日平均温度对菜用大豆产量的效应。结果表明:菜用大豆产量及主要经济性状受气象因素的影响较大,生育期、尤其是生育前期(出苗至第一朵花)受积温的影响最大,各生育阶段影响产量的主导因素是不同的,结荚期主导因素是日照,鼓粒期是雨量,成熟期是日平均温度。当结荚期累计日照时数在90h以上、鼓粒期累计雨量在91mm、成熟期日平均温度在27℃时产量最高。
The test data were sown in 1994, and the effects of accumulated temperature, cumulative sunshine hours, accumulated rainfall and daily average temperature on the yield of vegetable soybean were analyzed. The results showed that the yield and main economic traits of vegetable soybean were greatly influenced by meteorological factors. The growth period, especially the early growth period (from emergence to the first flower), was the most affected by accumulated temperature. The dominant factors influencing yield were different at each growth stage The dominant factor in the podding period is sunshine, the amount of rainfall during the drumming stage, and the average daily temperature at maturity. When the accumulated sunshine duration in podding stage was above 90h, the accumulated rainfall in druming stage was 91mm, and the highest average daily temperature at maturity was 27 ℃.
