摘要
为指导宁夏引黄灌区水稻生产过程中有机肥合理施用,分析对比了施用5种不同类型有机肥的水稻产量、土壤肥力和经济效益。结果表明:生物有机肥处理产量最高,有机肥源为酵素菌肥和酵素液肥的处理产量较低,产量分别比生物有机肥处理降低了23.4%和19.6%。生物有机肥和酵素液肥处理中土壤有机质、全氮、碱解氮含量较高。经济效益分析表明生物有机肥处理每667 m^2收益增86.9元,酵素菌肥和酵素液肥处理每667 m^2增收分别为317.8元和414.4元。综合考虑土壤肥力和经济效益等因素,生物有机肥和酵素液肥是较为合理的有机肥源。
In order to guide the rational application of organic fertilizer in rice production process in Ningxia Yellow River irrigation area,five different types of organic fertilizers in terms of the rice yield,soil fertility and economic benefits were analyzed and compared in this paper.The results showed that the yield of bio-organic fertilizer was the highest.The yield of other organic manure enzyme fertilizer or liquid enzyme fertilizer was lower,which were 23.4%and 19.6%lower than that of bio-organic fertilizer.The soil organic matter,total nitrogen and alkali nitrogen content were higher under bio-organic fertilizer and liquid enzyme fertilizer.The economic benefit analysis showed that the income of rice treated by bio-organic fertilizer increased by 86.9 yuan/667 m^2,and the income of rice treated by enzyme fertilizer and liquid enzyme fertilizer increased by 317.8 yuan/667 m^2 and 414.5 yuan/667 m^2,respectively.Considering factors such as soil fertility and economic benefits,bio-organic fertilizer and liquid enzyme fertilizer are more reasonable organic manure.
