冬小麦是二年生作物,生育期比较长。在其全部生育期中,越冬前的苗期占很重要的地位,此期是根系发育的重要阶段,又是形成有效分蘖的关键时期。因此,搞好冬小麦越冬前的田间管理,培育壮而不旺的麦苗,不仅能够保证小麦安全越冬,而且为来年丰收打下基础。一、全面普查,保证全苗。小麦产量的高低是由每亩穗数、每穗粒数和粒重决定的,要想有足够穗数,就必须有一定苗数。但一些地块因腾茬晚、底墒差、播期和播深不适,地面不平,明暗坷垃多和噎耧、地下害虫等原因,造成缺苗断垄时,要尽快采取措施, Winter wheat is a biennial crop, growing longer. In its entire growth period, pre-winter seedling occupies a very important position, this period is an important stage of root development, but also a key period for the formation of effective tillers. Therefore, improving field management of winter wheat before winter and nurturing strong but not vigorous wheat seedlings will not only ensure the safety of winter wheat, but also lay a foundation for the harvest in the coming year. First, a comprehensive survey to ensure that all seedlings. The level of wheat yield is determined by the number of ears per panicle, the number of grains per panicle and grain weight. To have enough ears, we must have a certain number of seedlings. However, some plots due to stubble late at night, at the end of poor soil moisture, sowing and sowing discomfort, ground uneven, rough and rub more and grubs, underground pests and other reasons, resulting in lack of seedlings broken ridge, we should take measures as soon as possible,
