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。如郑引一号小麦,千粒重的变化常在30—38克之间,甚至更大些。这是造成产量不稳和影响高产的重要因素。特别是单产在700斤以上的高产区,往往由于千粒重的影响,而不能高产再高产,已成为生产中一个突出而又急待解决的 In wheat production, grain weights fluctuate widely due to differences in climatic conditions and cultivation practices. As Zheng cited number one wheat, thousand grain weight changes often between 30-38 grams, and even larger. This is an important factor contributing to unstable production and high yield. In particular, high-yielding areas with a yield of more than 700 pounds per hectare often suffer from the effects of 1000-grain weight and can not produce high-yield and high-yielding products. This has become a prominent and urgent issue in production
