中文摘要	以中国北方为研究区域,检索已发表的相关文献田间试验数据,采用整合分析方法(Meta-analysis)系统探究种植年限对苜蓿地土壤水分和养分的时空效应。结果表明,与1~2龄苜蓿相比,随种植年限延长,土壤含水量和速效磷含量显著降低(P<0.05),变化率在-38.0%~-24.0%和-46 .5%~-20.2%之间,土壤有机质和全氮含量先增加后降低,变化率分别在7.2%~32.0%和-7.7%~15.7%之间。降水量对苜蓿土壤水分和养分含量影响强烈,与干旱区、半干旱区相比,半湿润区种植苜蓿的增碳固氮作用最佳,9~11龄苜蓿土壤有机质含量增长率高达43.1% (P<0.05),6~8龄苜蓿全氮含量增长率可达12.5%(P<0.05),同时也强烈消耗土壤水分和速效磷。与黄绵土、黑麻土和灰钙土相比,黑垆土种植苜蓿15年以上仍可显著提高土壤的有机质和全氮含量,增长率分别为19.9%和14.8%(P<0.05)。
英文摘要	The purpose of this research was to systematically explore the spatiotemporal effects of planting years on soil moisture and nutrient in alfalfa field by using meta-analysis method,based on the published field experiment data and literature retrieval in northern China.The results showed that compared with 1~2year old stands,soil moisture and available phosphorus content decreased significantly (P<0.05)with the increase of planting years,and the change rates were-38.0%~-24.0%and-46.5%~ -20.2%,respectively.The soil organic matter and total nitrogen content increased first and then decreased, and the change rates were 7.2%~32.0%and-7.7%~15.7%,respectively.Precipitation had a strongly influence on soil moisture and nutrient in alfalfa field,compared with the arid and semi-arid area, planting alfalfa in the semi-humid area had the best effect on carbon and nitrogen fixation.The growth rate of soil organic matter content of 9~11years old stands was as high as 43.1%(P<0.05),and the growth rate of total nitrogen content of 6~8years old stands was as high as 12.5%(P<0.05),and it also strongly consumed soil water and available phosphorus.Compared with loessial soil,haplic kastanzens and sierozem, alfalfa planted in dark loessial soil for more than 15years could significantly increase soil organic matter and total nitrogen content,with growth rates of 19.9%and 14.8% (P<0.05),respectively.Therefore, this study provides a strategy for farmers to determine the optimal growth period and improve the sustainability of the tillage system of precipitation and soil types.
