在小麦生产中,由于气候条件和栽培措施的差异,粒重的波动很大。这是造成产量不稳和影响高产的重要因素。因此,如何提高和稳定粒重,对获得小麦高产具有重大意义。为此,我们观察了不同类型春小麦品种籽粒形成、灌浆过程及营养条件对粒重的影 In wheat production, grain weights fluctuate widely due to differences in climatic conditions and cultivation practices. This is an important factor contributing to unstable production and high yield. Therefore, how to improve and stabilize grain weight is of great significance to obtain high yield of wheat. To this end, we observed the formation of different types of spring wheat varieties, grain filling process and nutrition conditions on the weight of the shadow
