| 摘 要： | 缺钾是水稻土的主要障碍因子之一,合理增施钾肥,既能促进水稻的营养代谢,又能大幅度提高水稻产量。为此本文利用5 a施肥定位监测资料,研究了钾肥在水稻土上的施用效果。结果表明:施用有机肥增施钾肥一般可增产6%左右,不施有机肥增施钾肥一般可增产4.9%左右。增施农肥及氮、磷、钾肥配合使用,才能保证水稻高产稳产。

| Abstract: | Potassium deficiency is an inhibitor of rice soil,so the allocation of potassium can not only accelerate vegetative metabolism,but also increase rice yield greatly.Based on the five year location monitoring data,the effect of potassium on rice soil was studied.The results showed that application of organic fertilizer and potassium could increase rice yield by 6% or so,and application of potassium with no organic fertilizer could increase yield by 4.9%.Compounding organic fertilizer with N,P,and K is an effective way to guarantee high yield and stabilization in rice. |
