为了摸索氯化钾在水稻上的经济有效的施用方法,近两年来,我们结合本县的实际情况,作了一些田间试验,现将试验结果报告如下。试验在本所及罗湖、温泉、河埠公社四个点上进行,试验田的土壤情况如表1所示。试验结果证明,早晚稻施用氯化钾,都有明显的增产效果。早稻施氯化钾每斤增产3.0—9.3斤 In order to explore the economical and effective application method of potassium chloride on rice, in the past two years, we have made some field experiments according to the actual situation in our county. The test results are reported as follows. The test was carried out at four sites of the company, Lo Wu, Hot Spring and Hebu Commune. The soil conditions in the experimental field are shown in Table 1. Test results show that morning and evening rice potassium chloride, have a significant yield-increasing effect. Early rice KCl per kilogram yield 3.0-9.3 kg
