施肥可以提高农作物产量,而目前广大农民普遍存在着乱施、滥施等施肥方法不当现象,肥料利用率只有30%左右,造成成本增加和环境污染。缓控释肥料示范试验由农业部全国农技服务中心下达安排,通过在水稻、玉米、小麦作物上的示范试验,校验其在大田中的应用肥效和经济效益。通过对试验示范结果的总结,为水稻缓控释肥推广应用提供一定的科学依据。
Fertilization can increase the crop yield. At present, widespread peasants are often misused, overused and improper fertilization methods. Fertilizer utilization is only about 30%, resulting in increased costs and environmental pollution. Controlled-release fertilizer demonstration test by the Ministry of Agriculture National Agricultural Service Center issued arrangements, through rice, corn, wheat crop demonstration tests to verify its application in the field fertilizer efficiency and economic benefits. Through the summary of the experimental demonstration results, provide a scientific basis for the popularization and application of controlled release fertilizer in rice.
