前言高产小麦干物质的积累规律与分配特点,在国内外均有研究。但是光合产物的积累、运转和分配因作物不同;同一作物,因品种不同;同一品种,因自然条件不同而有很大差异。我们栽培小麦的目的,主要是为了获得质高量大的籽粒。小麦从种子萌发到新种子的形成,株、蘖、穗和籽粒逐渐形成和发育,这个过程也是干物质积累和运转的过程。只有深刻认识 Preface High-yield wheat dry matter accumulation rules and distribution characteristics, both at home and abroad have been studied. However, the accumulation, operation and distribution of photosynthetic products are different due to different crops; the same crop is different due to different varieties; and the same variety is greatly different due to different natural conditions. The purpose of our cultivation of wheat, mainly in order to obtain high-quality large amount of grain. Wheat germinates from the seed to the formation of new seed, plant, tiller, ear and grain gradually formed and development, this process is also the process of dry matter accumulation and operation. Only a profound understanding
