宿豫区是一个典型的农业区,耕地面积4.6万多公顷。长期以来,农民习惯施肥只注重氮磷肥的施用,少施或不施钾肥,导致土壤肥力下降,养分失衡,致使小麦产量徘徊不前。2005年我们争取到国家测土配方施肥项目,根据本区土壤肥力状况和小麦的需肥规律,研制出适合本区的配方肥料,现将施用情况总结如下。
Suyu District is a typical agricultural area, more than 46,000 hectares of arable land. For a long time, farmers accustomed to fertilization only focus on the application of nitrogen and phosphorus, less or no potassium, resulting in decreased soil fertility, nutrient imbalance, resulting in wheat production stagnant. In 2005 we won the national soil testing and fertilizer project, according to the status of soil fertility in this area and the law of wheat needs fertilizer developed for this area of formula fertilizer, the application is summarized as follows.
