看麦娘是麦田主要杂草,发生面广量大,对三麦生产影响很大,严重田块因草荒耕翻重种,或造成麦子倒伏而减产。同时,近几年来,农田有机肥施用量减少,土壤有机质含量下降,耕性变差,影响高产。为探求免耕麦田的除草,改土和增产的三重效果。在小面积试验成功的基础上,去年秋播,全县大面积推广麦田复盖稻草19.3万亩,占三麦积面26.7％,特别是种田大户,麦田盖草面积达42％以上,实践证明,麦田盖草,方法简便,效果较好,受
Anemarrhena obliquus is the main weed in the wheat field. The occurrence of a large amount of large weeds has a great impact on the production of the San Mai wheat. In the meantime, in recent years, the amount of organic fertilizer applied to farmland decreased, the content of soil organic matter decreased, the tillage became worse, and the yield was high. To explore the tillage, soil improvement and yield increase in tillage-free wheat fields. On the basis of the success of the small area test, autumn broadcast last year, the county popularized a large area of wheat covering a total area of 193,000 mu, accounting for 26.7% of the total surface area of wheat, especially large farms with 42% coverage of wheat field cover. , Wheat cover grass, the method is simple, the effect is better, by
