| 摘 要： | 应用随机组合设计方法 ,研究了石灰性草甸土壤合理施用钾肥对水稻产量及其构成因素的影响 ,结果表明 :钾肥主要是通过影响有效重穗、结实率而促进产量的形成 ,对水稻的效重穗、结实率表现出极明显的促进作用。对水稻的产量有 Y=6 973.5 7.388X- 0 .0 2 80 X2的模式效应

| Abstract: | The effeef of K fertslization on rice yield on calcareows soil in Shanxi and the components of the yield were studied by using design of ordinary regression.The results show that:K fertilizer can significantly increase rice yield by significantly increasing effective ears and solid seed perent,and K fertilizer can significantly increase ears and solid seed percent by 0.732 X **and 0.0836X *.The regression equation between potash fertilizer(Z) and yield(Y) is =6973.5 7.388X **-0.0280X 2**. |
