摘要
[目的]研究喷施宝叶面肥对水稻的产量、干物重和养分吸收的影响。[方法]采用盆栽试验方案研究叶面肥不同施肥梯度下对水稻产量及养分吸收量的影响。[结果]喷施叶面肥可改善水稻生长状况,提高养分吸收能力,最终能够达到较好的叶面肥增产效果,合理施肥条件下喷施叶面肥增产可达12.14%。[结论]喷施叶面肥可促进水稻养分吸收,提高产量。
[Objective] The research aimed to study the effect of foliar fertilizer Penshibao on the yield,dry matter and nutrient uptake of rice.[Method] The influences of the application amount of fertilizer on rice yield and nutrient uptake were studied by the pot experiment.[Result] When foliar fertilizer was supplied,the nutrient uptake ability can be significantly improved and the yield-increase effects can be achieved.When foliar fertilizer was supplied under reasonable fertilization conditions,the yield can be significantly improved,reached 12.14% higher than control.[Conclusion] When foliar fertilizer was supplied,the nutrient uptake and yield can be improved.
