液体硅肥在水稻上的应用效果研究

Study on the Application Effect of Liquid Silicon Frtilizer on Rice

通过田间小区试验,研究叶面喷施液体硅肥对水稻产量及构成因素、稻米品质、氮素吸收利用以及经济效益等方面的影响。结果表明,叶面喷施液体硅肥能有效提高水稻有效穗数和每穗实粒数,提高了糙米率和精米率,降低了水稻垩白率、垩白度和直链淀粉含量,促进氮素的吸收和利用,可显著提高水稻产量、改善稻米品质、增加经济效益。

The effects of liquid silicon fertilizer sprayed on leaves on rice yield and its components,rice quality,nitrogen absorption and utilization,and economic benefits were studied through field plot experiments.The results showed that spraying liquid silicon fertilizer on the leaves could effectively increase the number of effective panicles and the number of grains per panicle,improve the rate of brown rice and milled rice,improve the chalkiness rate,chalkiness and amylose content of rice,promote the absorption and utilization of nitrogen,significantly increase rice yield,improve rice quality and increase economic benefits.
