[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 study the effect of large amount of water-soluble fertilizer on yield and economic benefit of late rice. [Method] A large number of elemental water-soluble fertilizers (trace elements type and powder) were tested simultaneously in Taoyuan and Yishan Heshan from July to November 2014. In the booting stage and filling stage, a large amount of water-soluble fertilizers (trace elements Type, powder), Heshan District booting at the booting stage, the full-leaf element spraying water soluble fertilizer (trace element type, powder). [Result] Applying water soluble fertilizers (trace elements and powder) could improve the yield components of late rice in both places, significantly increase the yield and economic benefits of late rice, and effectively promote the increase of yield and income of late rice. [Conclusion] A large number of water-soluble fertilizers (trace element type and powder) produced by Hunan TaiGu Biotechnology Co., Ltd. could be popularized widely on late rice.
