杂交稻不同时期喷施微量元素叶肥“稻多收”增产效果研究

Study of Field Increase Effect of "Daoduoshou"Leaf Spraied for Hybrid Rice

“稻多收”是一种新型水稻专用叶肥，含多种微量元素．本文报道“稻多收”的施用方法、增产效果及原因。结果表明叶面喷施“稻多收”能使杂交稻增产１６％～２０％，每亩净增收入９０．００～１００．００元，是微量元素科学服务于农业生产的一个重要方面，从而为杂交稻栽培提供了一条经济有效的增产途径。

Daoduoshou' was a new specialpurpose fertilizer of rice, which contained many traceelements. The applied technique. field increase effect and its mechanism of 'Daoduoshou'were given in this paper. The experimental result showed that as the leaves of hybrid rice was spraied with 'Daoduoshou',the grain field was increased by 16%￣20%.the net income pur mu was grown by 90￣140 yuan.the trace-element science was surved important respect of agriculture. The application of 'Daoduoshou' was a economic and effective method of increase productive for hybrid rice cultivation.
