功能型叶面肥对水稻产量与品质的影响
Effects of Functional Foliar Fertilizer on Rice Yield and Quality
摘要
Abstract
RT chelated fertilizer is a functional foliar fertilizer-with multiple chelated trace elements,which includes both foliar fertilizer and fruit fertilizer.In order to determine the suitable spraying way,field experiment with foliar fertilizer spraying at different N level was conducted in 2015.The results were as follows:the rice yield and quality were improved when the fertilizer sprayed at booting stage and heading stage,and also when sprayed at returning green stage and booting stage.The yield was improved prominently when the foliar fertilizer sprayed at returning stage and spraying fruit fertilizer at booting stage.The rice quality was improved greatly when the foliar fertilizer sprayed at seedling stage and tillering stage,and plus fruit fertilizer.The total number of roots and dry matter accumulation were improved when foliar fertilizer sprayed at seedling stage.Foliar fertilizer improved fertilizer efficiency at low N level.In conclusion,the best spraying date were booting stage and heading stage,and when foliar fertilizer and fruit fertilizer sprayed together showed the best effect.关键词
