摘  要：
[目的]通过施用石灰改变土壤酸碱度,提高水稻单产。[方法]在相同的自然条件下,按1hm2使用石灰用量不同,同时减少化肥用量,进行对比试验,总结出能夺取高产的最佳用量。[结果]山区水稻田施用石灰能调节土壤酸度,不同石灰用量并减少化肥用量与常规处理CK(不施用石灰)对比,能凸显不同的增产效果。[结论]山区稻田增施矿物源石灰并减少10%~20%化肥用量都能增产,石灰用量必须达到750 kg/hm2,增值最高,可以推广。

摘  要：
[Objective] The aim was to improve the rice yield, by changing soil p H with liming. [Method] In the same natural conditions, the optimum amount of energy to win high-yield was summed up, by comparison tests with useing different amounts of lime, and reducing the amount of fertilizer. [Result] The results showed that mountain rice fields liming could adjust soil acidity. The treatments with different amounts of lime and reduce the amount of fertilizer could highlight different yield contrast with treatment CK(no lime). [Conclusion] Adding lime mineral sources and reduce the amount of fertilizer by 10%-20% in mountain paddy could increase yields. The rice could obtain the highest value when the amount of lime reached 750 kg/hm2, and this amount could be extended.
