近年来,由于种植结构的调整,秋作物收获较晚,晚麦面积逐年扩大,一般比适播期晚半个月左右,有的甚至种霜降麦。这样的小麦往往“一根针”过冬,形成弱苗。但只要采取系统措施,晚麦同样可以获得较好收成,除应精细整地、施足底肥、足墒下种、防治病虫外,还要落实八项规范措施: 一、选好对路品种:晚麦由于播期迟,生长期短,分蘖少,所以应选择早熟且适宜密植的品种,以充分发挥其群体增产优势。 二、增粒缩行,适当密植。晚麦主要靠主茎成穗,
In recent years, due to the adjustment of planting structure, autumn crop harvest later, late wheat area expanded year by year, generally late than the suitable sowing period of about half a month, and some even frost and wheat. Such wheat is often “a needle” winter, the formation of weak seedlings. However, as long as systematic measures are taken, late wheat can also get better harvests. In addition to finely preparing soil, applying sufficient amounts of soil and adequate soil moisture, and controlling pests and diseases, eight normative measures should be implemented: Late wheat due to late sowing, short growth period, fewer tillers, it should be selected precocious and close planting varieties, in order to give full play to their group yield advantage. Second, grain shrinkage, appropriate close planting. Late wheat mainly by the main stem into the ear,
