在水稻的生长期间,及时补充肥料十分重要,只有这样才能满足水稻一定的生长需求。然而,在我国漏水田种植水稻的过程中,经常会出现肥料利用率较低的问题,发生水稻缺肥现象,同时,在一定程度上增加了栽培水稻的成本。而有效利用控释肥则能很好的改善这一问题。基于此,介绍控释肥的概念与优势,并通过试验来分析控释肥在水稻栽培上的施用效果。
It is important to replenish fertilizers on a timely basis during the growth of rice to meet certain growth needs of rice. However, in the process of planting paddy fields in our country, the problem of low utilization rate of fertilizers often occurs and the phenomenon of lack of fertilizers occurs. At the same time, the cost of growing rice is increased to a certain extent. Effective use of controlled release fertilizer can improve this problem. Based on this, the concept and advantages of controlled release fertilizers are introduced. The effects of controlled release fertilizers on rice cultivation are analyzed through experiments.
