早春是三麦分蘗向两极分化,幼穗加快发育,决定穗数和粒数的关键时期,也是病虫等自然灾害频繁发生,决定三麦能否高产稳产的关键时期。因此必须抓紧春季麦田管理。主攻目标:巩固分蘗争穗数,增花保花攻大穗,战胜灾害增粒重。根据苗情和气象条件,一般应以防冻害、防早衰、防湿害、防草荒、防病虫为中心,采取有效措施。 Early spring is the critical period for tillering of three wheat to polarization, the accelerated development of young panicles, the determination of panicle number and grain number, and the frequent occurrence of natural disasters such as pests and diseases as well as the determination of the high and stable yield of Sanmai. Therefore, we must seize the spring wheat field management. The main goal: to consolidate the number of tillers spike, increase flower spend big spike, overcome the disaster by grain weight. According to the conditions of seedlings and meteorological conditions, frost damage, anti-premature aging, moisture-proofing, prevention and control of pests and diseases should be taken as the center and effective measures should be taken.
