| 摘 要： | 目的]探明猪粪–秸秆还田的应用效果,确定最佳还田模式。方法]通过稻麦轮作田间试验,开展猪粪–秸秆还田处理对水稻、小麦生长性状及产量的影响研究,统计分析其经济效益及二氧化碳减排量,确定最佳的猪粪–秸秆还田模式。结果]猪粪–秸秆还田有利于水稻、小麦的生长,在"30%猪粪氮+20%秸秆氮+50%化肥氮"还田模式下,水稻、小麦产量均最高,分别为7 874.57和6 427.00 kg/hm~2,且稻麦轮作可节约成本5 146.35元/hm~2,水稻、小麦分别增收5 312.56和3 931.93元/hm~2,温室气体平均减排量为1.30 t/hm~2(按CO_2干基计算)。结论]"30%猪粪氮+20%秸秆氮+50%化肥氮"模式为猪粪–秸秆还田的最佳施肥模式。

Environmental and Economic Benefits Research on Rice and Wheat Rotation with Swine Manure Applying and Straw Returning |
| |
| Abstract: | Objective] The aim was to investigate the application effect of swine manure-straw returning and to determine the best mode. Method] A field experiment under rice-wheat rotation with different swine manure-straw treatments was conducted to study the growth charac-tertics and output of rice and wheat, calculate the economic benefits and carbon dioxide emissions reduction, analyze the best mode of swine manure-straw returning. Result] The swine manure-straw returning was conducive to the growth of crop, the highest output of rice and wheat were on the treatment of“30% swine manure and 20% straw and 50% chemical fertilizer”, there were 7 874.57 and 6 427.00 kg/hm2 , and saved cost about 5 146.35 yuan/hm2 , increased input 5 312.56 and 3 931.93 yuan/hm2 , the greenhouse gas emissions reduction was 1.30 t/hm2 ( calculate according to the carbon dioxide dry basis) . Conclusion] The treatment of “30% swine manure and 20% straw and 50%chemical fertilizer” was the best mode of swine manure-straw returning. |
