若干气象因子对毛豆75产量的效应研究
Effects of Some Meteorogical Factors on the Yield of Vegetable Soybean Variety 75
【摘要】 以2000年分期播种试验资料,分析积温、日照时数、累计降雨量和日平均温度对毛豆75品种产量的效应。结果表明:毛豆75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。当结荚期日照时数在95h以上、鼓粒期累计雨量在90mm、成熟期平均温度在26℃时产量最高。
【Abstract】 The effect of accumulative temparature,sunshining duration,rainfall and diurnal average temperature on the yield of vegetable soybean variety 75 were analysed with the experiments in different sowing periods in 2000.The results showed that the yield and main economic characters of vegetable soybean 75 were largely influenced by meteological factors during the growth stage,especially the early stages(from seedling emergence to first flowering), mainly by accumulative temperature.The dominant factors affecting the yield were different in various growth stages,i.e.the duration of sunshing in the pod-setting stage,rainfall in the pod-filling stage and average diurnal temperature in the maturing stage.The yield reached the highest level when there were more than 95 h of sunshing duration in the pod-setting stage,90mm of rainfall in the pod-filling stage and 26℃of diurnal average temperature in the maturing stage.
