大量元素水溶性肥料(微量元素型·粉剂)对桃源与益阳晚稻产量和经济效益的影响

Influence of Macroelements Water Soluble Fertilizer( Microelements Type,Powder) on Yield and Economic Benefits of Later Rice in Taoyuan and Yiyang

[目的]为研究大量元素水溶性肥料对晚稻产量、经济效益的影响。[方法]于2014年7-11月在桃源与益阳赫山区同时进行晚稻大量元素水溶肥料（微量元素型、粉剂）效果试验,桃源县在孕穗期、灌浆期喷施大量元素水溶肥料（微量元素型、粉剂）,赫山区在孕穗期、齐穗期叶面喷施大量元素水溶肥料（微量元素型、粉剂）。[结果]施用大量元素水溶肥料（微量元素型、粉剂）可以改善两地晚稻的产量构成因素,显著提高晚稻产量与其经济效益,对晚稻的增产、增收有有效的促进作用。[结论]由湖南泰谷生物科技股份有限公司生产的大量元素水溶性肥料（微量元素型、粉剂）可以在晚稻上大面积推广应用。

[Objective]The research aimed to explore the effects of macroelements water soluble fertilizer（ MWSF） on the yield and economic performance of later rice. [Method]MWSF（ microelements type,powder） effect test was carried out in Taoyuan and Yiyang from July to November in 2014 MWSF（ trace element type,powder） was sprayed on later rice in Taoyuan County at booting stage and filling stage,while in Heshan District MWSF（ trace element type,powder） was sprayed at booting stage and full heading stage. [Result]The application of MWSF（ trace element type,powder） improved the yield components,and significantly increased rice yield and economic benefits of late rice in Taoyuan and Yiyang. MWSF（ trace element type,powder） played an effective role in promoting the increase of later rice yield and economic benefits. [Conclusion] MWSF（ trace element type,powder） made by Hunan Taigu Bio-tech Co.,Ltd can be applied widely on late rice.
