我县通过土壤普查查明全县土壤严重缺钾。经过大面积和多点钾肥试验,证明施用钾肥有明显的增产效果。但在目前钾肥资源有限的条件下,摸清土壤的供钾水平,把有限的钾肥施到最需要的土壤上,经济合理利用钾肥资源。本文就我县近年来钾肥试验结果作一综述分析,以利提高钾肥利用率。 County through the soil census identified the county soil potassium deficiency. After a large area and more potassium fertilizer test, proved that the application of potassium fertilizer has obvious yield increase. However, under the current limited resources of potash resources, it is necessary to find out the level of potassium supply to the soil, apply the limited potassium fertilizer to the soil which is most needed, and utilize the potassium resources economically and rationally. This paper summarizes the results of potash fertilizer test in our county in recent years, in order to improve the utilization rate of potash fertilizer.
