我省近年来化肥施用量有很大增长,1980年全省化肥供应量169万吨(按标准肥计算),比1971年增加一倍,平均每亩耕地可分配到化肥89.2斤。其中氮肥54.9斤,磷肥32.6斤,钾肥0.9斤。氮、磷、钾的比例为1:0.43:0.01。这个比例数表明,我省化肥少磷缺钾,比例失调。这种状况已经影响到化肥的增产效果。过去每斤氮肥可增产稻

In recent years, there has been a great increase in the amount of chemical fertilizers in our province. In 1980, the province’s total supply of 1.69 million tons of chemical fertilizers (calculated based on standard fertilizers) doubled that of 1971, with an average of 89.2 kg of fertilizer per acre of cultivated land. 54.9 kg of nitrogen fertilizer, 32.6 kg of phosphate fertilizer and 0.9 kg of potassium fertilizer. The ratio of nitrogen, phosphorus and potassium is 1: 0.43: 0.01. This ratio shows that the province less phosphorus and potassium phosphorus, the imbalance. This situation has affected the yield of fertilizers. The past per kilogram of nitrogen fertilizer can increase rice
