水稻等氮条件下不同缓释肥肥效对比试验

Comparative test of fertilizer efficiency of different slow-release fertilizers in rice with equal nitrogen applications

试验设计了在水稻等氮情况下不同缓释肥的肥效对比试验。试验表明,施用缓释肥能够在减少一次分蘖肥的前提下,取代农户传统施用化肥模式,达到省工节本、增产增效的目的。但不同品牌缓释肥之间由于养分配方、缓释工艺存在差异,田间施用效果有所不同。好乐耕与多益成2个品牌缓释肥增产作用相对优于其他2个缓释肥品牌。

In this experiment,a comparative test of fertilizer efficiency of different slow-release fertilizers in rice under the condition of equal nitrogen was designed.The results showed that the application of slow-release fertilizer can replace the traditional application of chemical fertilizer by farmers on the premise of reducing the primary tillering fertilizer,so as to save labor and cost,increase yield and efficiency.However,due to the differences in nutrient distribution and slow-release processes between different brands of slow-release fertilizers,the field application effects are different.In this experiment,the yield increase effect of Haolegeng and Duoyicheng slow-release fertilizer were relatively better than that of the other two slow-release fertilizer brands.
