1977—1983年我们在胜利基点配合多种三熟轮作制的研究,对蚕豆良种启豆1号的分枝结荚习性和相应的栽培技术进行了研究。第一年种植1.7亩,平均亩产427斤,比本地种增产70％;第二年扩大种植到17亩,第三年起每年种植22亩。六年来,启豆1号虽在花荚期多年遇到春寒多雨的不利天气,但平均亩产仍达321.8斤;其中高产田块平均亩产437.8斤,最高的一年达到515斤。现就观察和研究的结果报告如下:
From 1977 to 1983, we studied the branch pod habit and the corresponding cultivation techniques of broad bean variety Qiaodou No.1 with its variety of three-cropping rotation system at Shengli base. The first year of planting 1.7 acres, an average of 427 pounds per mu, an increase of 70% than the local species; the second year to expand the planting to 17 acres, the third year of planting 22 acres each year. In the past six years, Qidou No. 1, despite many years of cold and rainy weather in the flowering and pod season, still recorded an average of 321.8 kg of mu per mu; among them, the yield of high-yield plots averaged 437.8 kg per mu and reached 515 kg in the highest year. The results of observations and studies are reported as follows:
