摘要
为减少化肥的施用量,降低小麦生产成本,提出通过提高千粒重增加小麦产量。分析千粒重的形成特点、亲本的经济系数,在此基础上,提出增加千粒重的方法,以为小麦增产提供指导。
To reduce fertilizer application and decrease production cost,this paper put forward the method of increasing yield by improving thousand kernel weight.The formation characteristics of thousand kernel weight and economic coefficient of parents were analyzed.On this basis,the method of improving thousand kernel weight was proposed to provide guidance for increasing wheat yield.
