有机肥类型及其施肥配比对稻田培肥效应和经济效益的影响
Effects of organic fertilizer type and fertilization on soil fertility and economic benefit of rice
摘要
Abstract
To study the effect of organic manure type and fertilization on rice yield, soil fertility and economic benefit,three types of organic fertilizer and two fertilization methods were performed in field conditions. The results showed that:under the same organic fertilizer conditions,the yield of 6:4 ferti-lizer management was higher than that of 6:3:1,while the yield of RCF was higher than that of BSF, OF, and CK in the two fertilizer managements. Under the condition of two fertilizer managements,the dry matter accumulation of RCF at the heading stage and heading to the mature stage was higher than that of BSF,OF and CK. Under the condition of 6:4 fertilizer management, the rice straw and grain nitrogen content in BSF and OF were higher than that of 6:3:1 in the mature stage. The nitrogen har-vest index,nitrogen transfer rate,nitrogen physiological utilization efficiency, and nitrogen agronomic efficiency were higher in 6:4 fertilizer management as well. Moreover,soil organic matter content was higher in 6:4 fertilizer management in the mature stage,which may contribute to the increasing of the soil fertility. Although the highest yield was present in RCF under 6:4 fertilizer management, howev-er,the net income of BSF was higher resulted from the higher input of fertilizer and fertilization under the condition of RCF and OF. All these evidences indicated that BSF under 6:4 fertilizer management was the best way to get higher economic benefits and to enhance the soil fertility in organic rice produc-tion practice.关键词
