近年来,丽江坝小麦产量不断提高,出现了不少千斤田块,一些高产试验田平均亩产超过了一千二百斤,高的达一千六百五十斤。为了进一步提高小麦单产水平,我们在黄山公社祥云大队太和生产队与队干部和广大社员一起开展科学实验。通过两年试验摸索,亩产千斤以上的小麦,存在着穗多穗大粒重的矛盾。单位面积内穗数增多,则穗小粒轻;片面追求穗重,则有效穗数偏少,均不能获得高产。如何正确地调节有效穗数与穗重这一对矛盾,现将我们两年观察记载的数据整理如下,供大家讨论,以求研究小麦高产规律,创造小麦单产向更高水平迈进。
In recent years, Lijiang dam wheat production continues to increase, there have been a lot of kilograms of plots, some high-yield test fields average yield over 1200 kilograms, up to 1,650 kilograms. In order to further raise the level of wheat yield, we in Huangshan commune Xiangyun Brigade Taihe production team and team members and members to carry out scientific experiments. After two years of trial and error tests, more than a kilogram of wheat yield per acre, there is the contradiction between the number of spike and grain size. Increasing the number of panicles per unit area, then earlets light; one-sided pursuit of panicle weight, the number of spikes less than effective, are unable to obtain high yield. How to correctly adjust the effective panicle and ear weight on this contradiction, now we observe the data recorded for two years to organize the following for your discussion, in order to study the law of high yield of wheat, wheat yield to create a higher level.
