近年来,西昌农专和凉山州农科所在蚕豆高产栽培方面根据蚕豆的生理特点和本地自然条件,采用相应的科学种田措施,1984年在西昌市郊获得亩产530斤的高产,1985年大面积试验示范,平均亩产达502斤,其中有10.8亩的单产超过600斤,有4.9亩超过640斤。其栽培措施主要顺应了蚕豆的以下生育特性。一、蚕豆喜温怕冻凉山州蚕豆为越冬作物,幼苗抗寒性不如小麦和豌豆,要求冬暖湿润日气候。幼苗能忍受的最低温度为3—4℃,营养生长的最适温为16℃,尤其是开花结荚期若遇低温寒潮,会严重影响
In recent years, Xichang Agricultural College and Liangshan Prefecture Department of Agriculture in the high yield of broad bean cultivation in accordance with the physiological characteristics of broad beans and local natural conditions, the use of appropriate scientific farming measures in 1984 in Xichang suburbs obtained a yield of 530 pounds per mu, 1985 large area Experimental demonstration, the average yield of 502 pounds per mu, of which 10.8 acres yield more than 600 pounds, 4.9 acres more than 640 pounds. The cultivation measures mainly conform to the following characteristics of faba bean. First, the broad bean hi warm afraid of Liangshan Mountain beans for the winter crops, cold hardiness than wheat and peas, requiring warm winter humid climate. The seedlings can tolerate the minimum temperature of 3-4 ℃, the optimum temperature for vegetative growth of 16 ℃, especially in flowering pods in case of cold spell, will seriously affect
