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