免耕机播麦高产的生育指标 由于高沙土地区三麦生长期间热量资源较丰富,无明显越冬期,加上土壤通透性好、养分释放快和蓄肥能力差,使免耕机播麦常出现前期早发,中期脱力,后期施肥水平高的易倒伏、施肥水平低的易早衰,影响三麦产量。为此,我们从1985年起进行了小麦高产试验,並在梁徐乡搞了有1342.5亩田的小麦免耕机条播的高产示范片,平均亩产371.5公斤,比一般大田增产17.9％,基本形成了免耕机播小麦的高产栽培技术体系。
Fertility index of no-tillage machine sowing high yield of wheat Due to abundant caloric resources during the growing period of high-sands soil, no obvious wintering period, coupled with good soil permeability, fast release of nutrients and poor storage ability, Often appear premature early, mid-term offspring, late high fertility lodging, fertilization low levels of premature aging, affecting three wheat production. To this end, we have carried out a trial of high-yield wheat since 1985 and produced a high-yielding demonstration film on a wheat no-tillage machine with a total area of 1342.5 mu in Liang Xu Township. The average yield per mu is 371.5 kilograms, an increase of 17.9% over that of ordinary fields. Formed no-tillage machine sowing wheat high-yield cultivation technology system.
