冬小麦从播种、出苗到抽穗,这一时期的麦田管理可分为几个阶段:从出苗到越冬是第一阶段为冬季管理;从返青到抽穗是第二个阶段为春季管理;从抽穗到成熟是小麦产量形成期,是决定产量高低的关键时刻,这是第三个阶段为后期。冬季麦田管理的主要任务是培育壮苗、保全苗,使苗匀、苗齐,增加分蘖数量。壮苗的标准,就是分蘖较多,粗壮、叶宽色深,根系发达。这是提高单株的穗数,争取大穗大粒的基础,是获得丰产的重要保证。
Winter wheat from sowing, emergence to heading, wheat field management during this period can be divided into several stages: from emergence to winter is the first phase of winter management; from green to heading is the second phase of spring management; from heading to maturity Is the formation of wheat yield is the key moment to determine the level of output, which is the third stage for the latter. Winter wheat field management is the main task of nurturing strong seedlings, seedlings preservation, the seedling uniform, seedling Qi, increasing the number of tillers. Strong seedling standards, that is, more tillers, stout, leaf width color depth, root system developed. This is to improve the number of spikes per plant, the basis for large ears big grain, is an important guarantee for high yield.
