小麦粒重的高低决定于品种特性和栽培的环境条件。在相同条件下,品种的千粒重往往差异较大,而同一品种在不同的气候和栽培条件下,其粒重也表现不一。在一定穗数和粒数的基础上,要获得较高的粒重,必需要了解不同品种粒重增长过程的特性,并据以运用合理的栽培技术,使品种的生产潜力得以充分发挥。本研究从灌浆生理入手,
The level of wheat grain weight depends on the variety characteristics and the cultivation of environmental conditions. Under the same conditions, the 1000-grain weight of the cultivars tended to vary greatly, while the same varieties under different climate and cultivation conditions also showed different weights. On the basis of a certain number of spikes and the number of grains, it is necessary to understand the characteristics of the grain weight increment process of different varieties on the basis of obtaining a higher grain weight. Based on the reasonable cultivation techniques, the production potential of the varieties can be fully utilized. This study started from the grouting physiology,
