摘要： 研究内蒙古农牧交错带不同施肥处理对土壤性质的影响,对该区域生态农业建设具有重要的意义.试验于 2006年在内蒙古呼和浩特市园艺中心试验地进行,设6 种不同施肥处理方式,种植作物为玉米(承339)、高丹草、苜蓿(阿尔刚金),观测了全生育期不同作物各处理的土壤理化性质.结果表明:有机肥与无机肥配施能够改善土壤容重、储水量和紧实度,有机肥与无机肥配施玉米区土壤容重下降幅度最大为11.76%,而苜蓿下降幅度最小为6.7%;在施肥处理为牛粪+氮肥+磷肥时,三种作物区在各个时期的储水量都较其他处理高;土壤紧实度随生育期的推进呈下降趋势,收获前后牛粪+氮肥+磷肥配施玉米、高丹草和苜蓿区分别下降32.14%,30.0%,28.8%.牛粪+氮肥+磷肥配施能够增加土壤养分,收获后与对照比较,玉米区土壤有机质提高了19.0%,土壤全氮、全磷、全钾分别提高17.8%,6.8%,13.2%,高丹草区和苜蓿区土壤养分也出现同样的结果.

Abstract: The objective of this study was to determine the influence of six fertilizer treatments，on Physical and chemical property in binding of agriculture and animal husbandry，Samples taken in the Huhhot garden center of Inner Mongolian. Planting crops as maize (Cheng 3359) ，Gaodan grass，a lfalfa (Al-Gon Jinn) ，we observed the growth stages of different crops，soil physical and chemical properties of each treatment. The results showed that: Organic manure and inorganic fertilizers can improve soil bulk density，soil water content and compaction，soil bulk density of corn was biggest drop of 11. 76% ，and the smallest decline in alfalfa was 6. 7% by organic manure and inorganic fertilizers treatments; In the treatment of organic manure + nitrogen + phosphorus，the three kinds of crop areas in different periods of soil water content is higher compared with other treatments; Soil hardness was downward trend with growth period of crops，organic manure + nitrogen + phosphorus fertilizer of corn，Gaodan grass and alfalfa fell 32. 14% ， 30. 0%， 28. 8% . Organic manure + nitrogen + phosphorus fertilizer can increase soil nutrients，compared with the control post-harvest，corn area increased by 19. 0% of soil organic matter，soil total nitrogen，total phosphorus，total potassium increased by 17. 8%，6. 8%， 13. 2% . Gaodan grass area and alfalfa soil nutrients also appeared the same result. Therefore，Organic manure + nitrogen + phosphorus fertilizer can be used as ecotone powerful restoration of soil fertility，f or binding of agriculture and animal husbandry provide a basis.
