中国小麦品种比较早熟,是在世界小麦中最突出的特点之一.许多早熟品种发育快,特别是后期灌浆脱水迅速,成熟很早.这是广大农民长期向自然作斗争,进行人工选择的结果.小麦在我国各地粮食生产和多种耕作栽培制度中占有重要地位.研究小麦的早熟性,选育更早更好的早熟小麦品种,有利于增加复种,提高粮产,防御灾害,实现小麦稳产高产.这对于落实毛主席备战、备荒、为人民的伟大指示,巩固和加强无产阶级专政,有着很大的现实意义. One of the most prominent features of wheat in the world is that the wheat varieties in China are relatively early-maturing, and many early-maturing varieties develop rapidly, especially in the late stage of grouting to dehydrate quickly and mature very early, which is the result of long-term struggle against nature and manual selection by peasants Wheat occupies an important position in the grain production and multi-cropping systems throughout China.It is very important to study the precocity of wheat and to breed the earlier and better early-maturing wheat varieties, which is good for increasing the multiple cropping, increasing the grain yield, preventing the disaster and realizing a stable yield of wheat This is of great practical significance for implementing Chairman Mao’s great instructions for preparing for war, preparing for the poor and for the people and for consolidating and strengthening the dictatorship of the proletariat.
