缓控释肥料是近年来重点推广的一种新型高效环保型肥料。采用缓控释肥料,通常一次施肥即可满足水稻整个生长期的需求,能够有效减少施肥次数,节省劳动力,提高化肥利用率,减少环境污染。通过开展水稻控释肥肥效对比试验,对推广该施肥方法有着重要的现实意义。 Controlled release fertilizer is focused on promoting a new type of highly efficient and environmentally friendly fertilizer in recent years. Controlled release fertilizers are usually used to meet the needs of the entire growth period of rice through a single fertilization. This can effectively reduce the number of fertilizations, save labor, increase fertilizer utilization, and reduce environmental pollution. Through carrying out contrast test on the effect of controlled release fertilizer on rice, it has important practical significance to popularize the method of fertilization.
