摘要
研究结果表明 ,施用粉煤灰多元复混肥 ,能增加土壤养分 ,满足水稻对多种营养元素的需求 ,促进水稻生长发育 ,提高水稻产量和经济效益。不同配方各处理产量与对照比均达到 1%显著差异。田间试验以 3∶1∶4和 3∶1∶2配方最佳 ,早、晚稻分别比对照增产 13.3%、10 .6 %和 10 .4 %、9.8%。
The result of the study indicates that applying polybasic compound fertilizer of powdered coal ash increases the content of nutrients in soil, meets the need of rice for various nutritional elements, enhances the growth and development of rice, and increases rice production and economic performance. The yields from the treatments with different formulae are higher by 1% on average than that of the control making remarkable difference. According to the field experiment, the formule of 3∶1∶4 and 3∶1∶2 are optimum, which increase the yields of early and late rice by 13.3%, 10.6% and 10.4%, 9.8% respectively compared with that of the cotrol.
