小麦的产量是由亩穗数、穗粒数和千粒重三者构成。亩穗数的多少是制约产量的决定因素,亩穗数由基本苗和分蘖多少决定。要确保高产所需的亩穗数,就应在适期晚播、科学界定小麦播量的基础上提高播种质量。小麦播种质量主要受前茬作物秸秆数量、秸秆粉碎质量、整地质量和播种质量四种因素影响,针对上述原因可采取以下解决方法。
The yield of wheat is composed of the number of ears per ear, the number of grains per ear and the weight of 1000 grains. Mu number of spikes is the limiting factor of yield, acre spike number of basal seedlings and tillers decided. To ensure the high yield of the required number of ears per mu, it should be late sowing season, scientifically define the sowing of wheat on the basis of improving seeding quality. The quality of wheat sowing is mainly affected by four factors: crop stalks, stalk shredding quality, site preparation quality and sowing quality of the stubble crop. The following solutions can be taken for the above reasons.
