近几年来,我区由于贯彻以水定地,适当压缩小麦播种面积后,小麦单产、总产都在不断提高。为了保证小麦产量向新的水平突破,必须大幅度提高单产,这就进一步要求我们按照小麦的生长发育规律来制定正确的栽培技术措施。为此,我所近两年来,观察了小麦幼穗分化进程,为制定栽培技术提供了一些科学依据。 一、几个冬麦品种幼穗分化进程:
In recent years, due to the implementation of the water area in our region, the appropriate reduction of wheat sown area, wheat yield, total output is constantly rising. In order to ensure a new level of wheat yield breakthrough, we must substantially increase yields, which further requires that we follow the law of wheat growth and development to develop the correct cultivation techniques. For this reason, in the past two years, I have observed the process of spike differentiation in wheat and provided some scientific evidence for the development of cultivation techniques. First, several winter wheat varieties spike differentiation process:
