摘要：

施用合适的叶面肥有利于水稻生长和产量提高。本试验以5种不同类型的叶面肥为材料，分析比较了施用不同叶面肥对水稻养分吸收、产量及二化螟危害的影响。结果表明，5种叶面肥均能提高水稻体内氮（N）、磷（P）、钾（K）、钙（Ca）、镁（Mg）、铁（Fe）、锌（Zn）和钼（Mo）等营养元素的含量，显著提高水稻产量3.88%~7.47%，其中，瑞普生和丰瑞达牌叶面肥的增产效果较为显著，其次为彪榜、行万里和天需牌叶面肥。通过分析产量构成因子后发现，施用叶面肥增产的主要原因在于提高了每穗粒数。行万里牌叶面肥可以显著降低二化螟引起的水稻枯心丛率和枯心株率，其余叶面肥对降低水稻枯心丛率和枯心株率没有显著效果。施用不同叶面肥处理的经济效益表现为丰瑞达>瑞普生>彪榜>天需>行万里。在实际生产中可根据需要选择适宜的叶面肥品种。

Abstract:

The application of appropriate foliar fertilizer is beneficial to the growth and yield of rice. The effects of five types of foliar fertilizers on nutrient absorption, yield of rice and damage of Chilo suppressalis were compared in the experiment. The results showed that all the five types of foliar fertilizer could increase the contents of N, P, K, Ca, Fe, Mg, Zn and Mo in rice root and shoot, and significantly increase rice yield by 3.88%-7.47%. Among them, RUIPUSHENG and FENGRUIDA had the most significant effect on yield increase, followed by BIAOBANG, XINGWANLI and TIANXU. The main reason of increasing yield by applying foliar fertilizer was the increase of grain number per panicle. The application of XINGWANLI foliar fertilizers significantly decreased the damage percentage of rice clusters and the damage percentage of rice plants, while the other foliar fertilizers had no significont effect on the damage percentage of rice clusters and the damage percentage of rice plants. The economic benefits after applying foliar fertilizers were as follows: FENGRUIDA > RUIPUSHENG > BIAOBANG > TIANXU > XINGWANLI. The foliar fertilizer varieties can be selected according to the actual needs in production.
