在各种土壤上氮磷化肥配合施用,是提高产量和肥料利用率的有效措施。化肥增产率的大小,直接影响作物产量。如何合理搭配化肥比例,提高增产效率,是当前极为重要的一个问题。小麦是我县主栽作物,播种面积占总面积的40～50％,搞好化肥比例,进一步提高小麦产量,经三年试验初步得出较合理的比例。
In a variety of soil nitrogen and phosphorus fertilizer with the application, is an effective measure to improve yield and fertilizer utilization. Fertilizer rate of increase in size, a direct impact on crop yield. How to properly match the proportion of fertilizers to increase the efficiency of production is an extremely important issue. Wheat is the main crop of our county, the sown area accounts for 40 ~ 50% of the total area, improve the proportion of fertilizers and further improve the yield of wheat. After three years of trial, a reasonable proportion has been initially obtained.
