稻麦轮作体系下氮素的优化管理

稻谷和小麦是中国主要的粮食作物,对于中国这个农业大国来说,提高粮食产量迫在眉睫。而氮素为作物重要的营养元素之一,优化管理氮素,对提高作物的产量和质量起着非常重要的作用。人们通过大量种植经验和试验研究得出,可以采用以下5种可行的技术措施有效优化氮素,即确定氮肥施用量、氮肥深施、秸秆还田,平衡施肥和配施有机肥。而在实际生产中,因地制宜,将5种技术措施合理综合使用,将能够收获高产优质的稻谷和小麦。

The Optimal Management of Nitrogen Under Rice-Wheat Rotation System

The rice and wheat are the main food crops and the increased food production is urgent for China which is a major agricultural country.As one of the most important nutrients of crop,the optimal management of nitrogen,and increase crop yield and quality play a very important role.People grow through experience and testing of a large number drawn,you can use the following five possible technical measures to optimize the nitrogen,which was to determine nitrogen fertilizer,nitrogen fertilizer deep application,straw,balanced fertilization and combined with organic manure.In actual production,according to local conditions,five technical measures will be reasonably and comprehensivey taken,will be able to harvest high quality rice and wheat.
