| 摘 要： | 采用ASI方法检测土壤养分并进行水稻测土配方施肥试验。结果表明,水稻产量以OPT最佳施肥量为最高;OPT处理比常规施肥增产39.3 kg/667 m2,增幅7.13%,增收70.3元(人民币,下同)/667 m2;在同一氮肥水平下,使用锌肥和钾肥的增产作用较显著;适当减少氮肥和磷肥的用量,可提高水稻产量和经济效益。 |

| Abstract: | Based on the soil nutrients tested by the ASI method an experiment of precision application of fertilizer to rice field was carried out. The experimental result showed that the rice yield under the OPT treatment was the highest, the yield was 39.3 kg/667m^2 higher than that under the conventional fertilizer application, or 7.13% increase rate, and the net income increment was 70.3 yuan/667m^2. Under the same amount of N fertilizer applied, the effect of applying K2O and Zn was significant. Appropriate decrease in the amount of N and P fertilizer applied could increase the yield and economic benefit of rice production. |
