【摘要】 采用田间小区和盆栽试验方法,研究了利用城市生活垃圾配制的有机—无机复混肥对玉米生产和土壤理化性质的影响。结果表明,当施用垃圾复混肥中的氮量约为商品复合肥纯氮量的一半时,玉米小区经济产量和盆栽生物量分别比不施肥增加29.73%和184.8%,比商品复合肥减产3.51%和18.89%;垃圾复混肥施用量与复合肥纯氮量相等时,分别比不施肥增产38.58%～51.93%和262.0%～239.3%,比商品复合肥增加3.07%～13.00%和3.07%,其增产效果显著。长期施用垃圾复混肥还可以补充和增加土壤有机质和养分,改善土壤理化性状,提高土壤肥力。更多还原

【Abstract】 The effects of organic -mineral mix ing composts derived from municipal garbage on corn production and soil physico-chemical properties were studied th rough field experiment and pot experiment.The results showed that while the amount of nitrogen in garbage -fertilizer mixed compost applied was about 1/2of that in the c ompound fertilizer,corn yield econ omically and biomass increased by 29.73%and 184.8%,resp ectively,compared with the control,and decreased below 3.51%and 18.89%,re-spectively,compared with applying compound fertilizer,while the amou nt of nitrogen in garbage -fertilize r mixed compost applied was equal to that in the compound fertilizer,corn yield economically and biomass increased by 38.58%～51.93%and 262.0%～239.3%,respectively,compared wit h the control,and by 3.07%～13.00%an d 3.07%,respectively,compared wit h applying compound fertilizer.The effects of the yield increase were up to significant.Along termapplication of the m ixed compost will provide organic matter and nutrient to soil,improving physicochemical properties and fertility of soil,and also being an effective way of soil resource sustainable utilizing and sanitizing municipal environment.更多还原
