利用山东省夏大豆联合区域试验资料和各地气象资料.经过统计分析指出,在温、光、水三因子中,供水量对夏大豆产量影响最大;苗期阶段的供水量是对夏大豆产量影响最大的生育阶段;得出了丰收黄、文丰五号等夏大豆品种各个生育阶段的适宜供水量,形成1斤大豆籽粒每个生育阶段所需要的水量。搞好苗期阶段的供水,是山东省夏大豆大幅度增产的关键。
Using the experimental data of summer soybean in Shandong Province and the meteorological data of different places, the statistical analysis shows that the water supply has the greatest impact on the yield of summer soybean in the three factors of temperature, light and water, and the water supply in the seedling stage is affecting the production of summer soybean The maximum fertility stage. The suitable water supply of summer soybean varieties, such as Fengronghuang and Wenfeng No.5, was obtained and the amount of water required for each growth stage of 1 kg soybean was formed. To improve water supply at the seedling stage is the key to a substantial increase of summer soybean in Shandong Province.
