我县常年种植15—20万亩小麦,其前作绝大部分为红苕,由于大面积红苕的收挖必须在立冬过后,所以常常造成小麦迟播减产。全县常年迟播小麦面积约5万亩左右,成为小麦生产的拉产田。为了探索迟播小麦高产栽培的规律,我们采用正交试验法,对不同浸种催芽方法和催芽程度,不同用种量及氮、磷、钾肥不同施用水平诸因素在迟播小麦高产栽培中的产量效应(主效应)进行了初步研究。
My county planted 15-20 million mu of perennial wheat, before the vast majority of red cicada, due to the large area of red clumps must be collected after the beginning of winter, it often results in delayed sowing of wheat. County perennial late wheat area of about 50000 acres, become a production of wheat production. In order to explore the law of high-yielding cultivation of late-sowing wheat, orthogonal test was used to study the effects of different seed soaking methods and degree of germination, different used rates and different application levels of nitrogen, phosphorus and potassium fertilizers on high-yielding late-sowing wheat Effect (main effect) conducted a preliminary study.
