不同缓(控)释肥对水稻化肥减量增效及土壤环境的影响
Effects of Different Slow(Controlled)Release Fertilizers on Reduction and Efficiency of Rice Chemical Fertilizers and Soil Environment
摘要
Abstract
To explore the efficiency of different slow(controlled)release fertilizers in rice,this experiment set up four treatments of fertilization:conventional fertilization,Maoshi controlled-release fertilizer,Sirte slow-release fertilizer,and Maoshi dual control slow-release fertilizer.The rice yield and soil chemical properties were measured in each plot,and the effects of different slow(controlled)release fertilizers on reduction and efficiency of rice fertilizer,soil fertility and determination of soil chemical properties were evaluated using combination of the analysis of soil enzyme activity and microorganism indicators.The results showed that when fertilizer nutrients quantity decreased by 13%,the theoretical yield of rice was consistent with the actual yield,with Maoshi dual control slow-release fertilizer treatment＞Sirte slow-release fertilizer treatment＞conventional fertilization treatment＞Maoshi controlled-release fertilizer treatment;under the application of slow(controlled)release fertilizer in rice,the cost-saving and fertilizer reduction effect of Sirte slow-release fertilizer and Maoshi dual control slow-release fertilizer were the better;the total nitrogen,total phosphorus,and total potassium content of rice grains and straw treated with Sirte slow-release fertilizer and Maoshi dual control slow-release fertilizer were relatively higher.Maoshi dual control slow-release fertilizer treatment had the best effect on improving various chemical and biological characteristics of soil.Based on the above results,it can be concluded that the application of Maoshi dual control slow-release fertilizer had the best effect.关键词
