我们栽培小麦的目的就是为了获得高额的籽实产量。众所周知,产量的构成因素,决定于每亩穗数、每穗粒数和籽实重量。而幼穗发育的好坏对成穗数和穗粒数都有很大影响,尤其直接关系到每穗粒数的多少。对小麦幼穗分化进行观察,深入了解它的各个阶段时间进程以及与外部形态的相关性,就可以采取相应的栽培措施,准确地运用肥、水等物质条件,达到穗大粒多,夺取高产的目的。
The purpose of our cultivation of wheat is to obtain high seed yield. As we all know, the composition of the yield depends on the number of spikes per acre, grain number per spike and seed weight. The development of young panicles on the number of spikes and grains have a great impact, especially directly related to the number of grains per spike. Observing the differentiation of wheat spike and understanding the time course of its stages and the correlation with the external morphology, we can take appropriate cultivation measures, accurately use the material conditions of fertilizer and water, reach the spike of large grain, and seize high yield purpose.
