准确的播种量能够保证小麦有足够、合理的基本苗,是培育壮苗,争取小麦丰产的重要环节。小麦播种量的多少决定于计划的基本苗数、种子发芽率、出苗率及千粒重等因素。怎样确定播种量呢?可用下式计算。播种量(斤/亩)=(?)例如:计划基本苗为25万、种子发芽率为80%,田间出苗率为75%,千粒重为32克,那么 Accurate sowing to ensure that wheat has enough, a reasonable basic seedlings, is to cultivate strong seedlings, strive for an important part of wheat yield. The amount of wheat seeding depends on the number of planted seedlings, seed germination rate, emergence rate and 1000-grain weight and other factors. How to determine the amount of seeding? Can be calculated using the following formula. Sowing rate (kg / mu) = (?) For example: the plan basic seedlings is 250,000, seed germination rate of 80%, field emergence rate of 75%, grain weight of 32 grams, then
