为减少肥料用量,提高肥料利用率,保护农业生态环境,在江淮地区研究稻麦两熟制小麦秸秆全量还田水稻肥料减量化栽培技术。前茬小麦秸秆粉碎全量返田,设7个施氮水平,三次重复,大田按试验设计施肥,通过试验获取不同施氮水平下的差异。通过试验得知在小麦秸秆粉碎全量还田的条件下,减少肥料施用量,可增加利用的高效性,节约生产成本,减少农业环境污染。
In order to reduce the amount of fertilizer, improve fertilizer utilization, and protect the agricultural ecological environment, in the Jianghuai region research rice and wheat double cropping wheat straw in full return to paddy rice reduction cultivation techniques. The former wheat straw was pulverized and returned to the field. Seven nitrogen levels were set and repeated three times. The field was designed and fertilized according to the experiment, and the differences among different nitrogen levels were obtained through experiments. The experiment shows that when the wheat straw is crushed and returned to the field, reducing the amount of fertilizer applied can increase the efficiency of utilization, save the production cost and reduce the agricultural environmental pollution.
