为了探讨冬种大豆不同生育时期与气象条件的关系,趋利避害,选择适宜的播种期,提高冬大豆产量,以促进冬大豆生产发展,我们从1980年冬种开始,连续三年进行了冬大豆不同播期的试验研究。
In order to discuss the relationship between different growing stages of winter soybean and meteorological conditions, to seek benefits and avoid disadvantages, to select suitable sowing dates, to increase winter soybean production and to promote the production of winter soybean, we started from winter wheat in 1980 and continued for three years Experimental Study on Different Sowing Date of Winter Soybean.
