摘要
在水稻田施用生石灰调节土壤酸度,结果表明:施用石灰后,土壤pH值短期增加明显,以每667 m2施石灰150 kg处理水稻产量较高,两季合计885 kg,增产8.8%,净增收170元。
Quicklime was used to adjust soil acidity of double cropping paddy field in this study. The results indicated that the pH value was significantly enhanced in short term; higher rice grain yield （ 885 kg per 667 m^2 in double cropping sea-sons） was achieved in the treatment of applying 150 kg quicklime per 667 m^2 to paddy field, increased by 8.8% and the net income reached 170 RMB Yuan.
