小麦产量是由植株本身的生育特点与外界环境、栽培条件综合作用,影响每亩穗数、每穗粒数和子粒饱满度决定的。因此,首先要了解小麦的生理特点和生长发育规律及其对产量构成的影响,以及采取合理的栽培管理措施,夺取较高的产量。一、小麦种子发芽至分蘖发生阶段的生物学特性 (一)小麦品种特性与阶段发育良种具有高产优质、对病虫害抵抗力强的内在潜力。不同品种整个生活周期包括若干阶段,其中与生产关系最密切的是春化阶
Wheat yield is determined by the plant’s own reproductive characteristics and the external environment, the combined effect of cultivation conditions, affecting the number of spikes per panicle, grain number per panicle and grain fullness decision. Therefore, we must first understand the physiological characteristics of wheat and the law of growth and development and its impact on the composition of the output, and take reasonable cultivation and management measures to capture higher yields. First, the biological characteristics of wheat seedling to tiller stage (A) the characteristics of wheat varieties and stages of development with high yield and high quality, resistance to pests and diseases of the inherent potential. The entire life cycle of different varieties includes several stages, of which the most closely related to production is vernal
