根据全国大豆品种生态试验1980—1982年在28个试验点96个栽培品种所得生育期结果的分析,可以看出大豆在不同生育阶段的日数表现上,因受大豆品种的生育特性和各地不同试点光照和温度的影响呈现很大的差异,其生育日数的长短呈现连续性的变异。本文依据大豆品种在不同地区的播种期,成熟期二个时期的资料,进行中国大豆品种生育期分组的研究,将中国大豆品种划分为12个生育期组,确定代号为C_1—C_(12)。对我国大豆科研与生产有一定的意义。
According to the analysis of the results of the growth period of 96 cultivars cultivated in 28 test sites from 1980 to 1982 in the national ecological experiment of soybean varieties, it can be seen that the soybean performance at different growth stages depends on the reproductive characteristics of soybean varieties and different pilot sites The effects of light and temperature show great differences, and the length of their days of birth presents a continuous variation. Based on the data of soybean sowing period and maturing period in different regions, this paper studied the growing stages of Chinese soybean varieties and divided the Chinese soybean varieties into 12 growing groups and identified them as C_1-C_ (12) . Soybean research and production in our country have some significance.
