柳州地区素有种植大豆的习惯,尤以春大豆的面积最大,并已发展为我区春大豆主栽区之一。但寒、旱、涝和高温等不利气象条件对大豆生产危害较大,产量低而不稳定。本文以 1985年我站大豆分期播种资料 (北京豆和75-375两个春型品种;播期从二月下旬至九月上旬每旬逢六播种,每品种共20期;每期每品种设两个重复,每亩2万亩,小区面积0.025亩;观测生育期、生长量和产量性状等),通过对大豆不同季节播种产量要素的气象条件分析,鉴定其气候适应性,为进一步发展大豆生产,合理利用气候
Liuzhou area known as the habit of growing soybean, especially the largest area of spring soybeans, and has developed into one of the main areas of our district spring soybean. However, adverse weather conditions such as cold, drought, waterlogging and high temperature are more harmful to the production of soybean and the yield is low and unstable. In this paper, the soybean planting date of our station in 1985 (Beijing beans and 75-375 two spring type varieties; sowing date from late February to early September every seventy every six seeding, a total of 20 varieties per period; Two repetitions, 20,000 mu per mu, plot area of 0.025 mu; observed growth period, growth and yield traits, etc.), through the analysis of meteorological conditions of seeding yield elements of soybean in different seasons, identified its climate adaptability, for the further development of soybean Production, rational use of climate
