多穗高粱从1959年引进,经三年种植,证明是一个优良的高产品种.1961年生产兵团扩大种植面积达40万亩,但普遍反映欠熟,千粒重下降,减了产,并影响了秋粮总产的增长.这样看来,在新疆今后能否继续推广这一品种呢?从自然气候条件看,除部分地区确因条件限制,不能种植或只能少量种植外,大部分地区,肯定是能够种植的.1961年多穗高粱减产问题在于栽培年限短,群众对其生长发育特点认识浅、掌握不够,推广后技术指导工作没有跟上,技术措施不当.为了正确解决这个问题,我们首先要了解多穗高粱的生物学特性、
Multi-spike sorghum introduced from 1959, after three years of planting, proved to be an excellent high-yield varieties .In 1961, production Corps to expand the planting area of 400000 acres, but generally reflects the undermature, 1000-grain weight decreased, reduced production, and affect the autumn From this point of view, whether Xinjiang can continue to promote this species in the future? From the natural climatic conditions, except in some areas because of limited conditions, can not be planted or only a small amount of cultivation, the vast majority of areas, it is certainly Can be planted in 1961. The problem of yield reduction of multi-spike sorghum in 1961 lies in short cultivation years, lack of understanding of the characteristics of its growth and development by the general public, insufficient follow-up of technical guidance and improper technical measures. In order to solve this problem correctly, Learn more about the biological characteristics of sorghum,
