在毛主席革命路线指引下,经过无产阶级文化大革命,农业学大寨运动蓬勃发展,随着生产条件的迅速改变,小麦生产发展很快。怎样继续提高小麦的产量呢?目前,有两种途径:一种是选育推广抗病、抗倒的高光效品种,另一种是改革栽培方法充分利用光能夺取高产。在利用光能方面,几年来我们对宽窄行等行距及大背垄几种不同的播种方式进行对比,通过试验证明,宽窄行播种法增产幅度大,效果明显,概括起来,有六条好处。群体不变小,光照解决了要夺取小麦高产,必须争取穗多、穗大、籽粒饱。在生产中,保证一个合理的群体,是争取穗多的前提。分蘖是小麦固有的特性。分蘖率
Guided by Chairman Mao’s revolutionary line and through the Great Proletarian Cultural Revolution, the Dazhai Campaign for Agricultural Science flourished. With rapid changes in production conditions, wheat production developed rapidly. How to continue to increase wheat yield? At present, there are two ways: one is the selection and promotion of disease-resistant and lodging-resistant varieties of high light efficiency, the other is the reform and cultivation methods to make full use of light to seize high yield. In the utilization of light energy, we have compared several kinds of sowing ways such as wide and narrow row spacing and big ridge in recent years. It is proved through experiments that there is a big yield increase in broad and narrow row sowing method. In summary, there are six advantages. Groups do not become smaller, light to solve the problem of winning high yields of wheat, must fight spikes, spike, grain full. In production, to ensure a reasonable group is the prerequisite for obtaining more spikes. Tillering is an inherent property of wheat. Tilting rate
