晚茬小麦由于播种期较晚,冬前生长期较短,长势弱,产量较低,往往是提高小麦产量的“拉脚田”。近年来文登市推广了晚茬麦的高产栽培技术,收到了较好的效果,一般亩产可达300公斤左右。 1.采用沟种形式。四犁起垄,沟底集中施肥小麦种在沟底,这种形式能够提高地温、蓄墒、挡风拦雪,防寒防旱,利于小麦苗期生长和安全越冬,促蘖增穗,中后期通风透光好,边行优势大,植株 Crops of late-cropping wheat are often the “pull-foot-fields” for increasing wheat production due to late seeding periods, shorter winter-growth periods, weak growth and lower yields. Wendeng City in recent years to promote the late crop of high-yielding cultivation techniques, has received good results, generally up to 300 kilograms per mu. 1. The use of furrows form. Four plows Ridge, ditch concentrated fertilization of wheat planted in the ditch, this form can increase ground temperature, soil moisture, wind and snow, cold and drought, which will help wheat seedling growth and safety of winter, tillering by ear, the late Ventilation and light, edge line big advantage, plants
