随着农业生产的发展,氮磷化肥施用水平的提高,以及杂交水稻大面积的连续栽种,我省稻田缺钾现象越来越严重。增施钾肥已成为取得高产稳产的重要措施,氮钾配比也成为衡量农业集约化程度的重要标志。由于我国钾肥资源紧缺,近年生产及进口数量虽有所增加,但仍满足不了生产实践的需要,为使有限的钾肥发挥较大的经济效益,就要特别注意钾肥的合理施用,下面就这个问题谈几点意见.
With the development of agricultural production, the improvement of application level of nitrogen and phosphorus fertilizers, and the continuous cultivation of hybrid rice in large area, the potassium deficiency phenomenon in rice fields in our province is more and more serious. Increasing potash fertilizer has become an important measure to achieve high and stable yield. The ratio of nitrogen and potassium has also become an important indicator to measure the degree of agricultural intensification. Due to the shortage of potash resources in our country, although the production and import quantity have increased in recent years, they still can not meet the needs of production practice. In order to make the limited potash fertilizer exert great economic benefits, we should pay special attention to the rational application of potash fertilizer. Talk a few comments.
