中文摘要	研究北疆平原荒漠区小麦-苜蓿轮作下土壤理化性质的动态变化,揭示粮草轮作过程中土壤盐碱度和养分的消长规律,旨在为该地区种植结构的调整和农田生态系统的可持续利用提供科学依据。在小麦轮作苜蓿的中低产田中,连续5年调查土壤全盐量、pH值、有机质和氮磷钾。结果表明:小麦地轮作苜蓿有效降低了土壤含盐量和pH值,轮作第4年土壤含盐量由轮作前0.79g/kg降低到0.63g/kg,土壤pH值平均降幅为6.64%,土壤有机质平均增幅为19.07%;土壤中全氮含量增加,由轮作前0.52g/kg提高到0.65g/kg,水解性氮含量较轮作前显著降低;磷含量呈上下波动,轮作4a全磷由0.98g/kg降至0.93g/kg,有效磷由6.18g/kg降至2.97g/kg;土壤速效钾含量呈先减少后增加的态势,轮作后速效钾含量的最低值为260.44mg/kg,处于富钾状态。在北疆平原荒漠区的粮食耕作系统中引入苜蓿可有效提高土壤有机质含量,增加全氮的储备量,降低盐碱度。在苜蓿生长第4a需适当补充氮肥和磷肥,无需施入钾肥。
英文摘要	The changes of soil physical and chemical properties under wheat-alfalfa rotation in the desert area of Northern Xinjiang Plain were studied to reveal the dynamic pattern of soil salinity and nutrients in the process of grain-alfalfa rotation,therefore providing scientific basis for the adjustment of planting structure and sustainable utilization of farmland ecosystem.The soil total salt content,pH value,organic matter,nitrogen,phosphorus and potassium were followed up for 5years in wheat-alfalfa rotation system.The rotation of alfalfa in wheat effectively decreased soil salt content and pH value,with soil salt content reduced from 0.79g/kg to 0.63g/kg in the fourth year of rotation,and an average decrease in soil pH by 6.64%,an average increase in soil organic matter by 19.07%.Soil total nitrogen content increased from 0.52g/kg before rotation to 0.65g/kg,and the hydrolysis nitrogen content was significantly lower than that before rotation.Soil phosphorus content fluctuated up and down,and the total phosphorus decreased from 0.98g/kg to 0.93g/kg and the available phosphorus decreased from 6.18g/kg to 2.97g/kg in the four-year rotation.Soil available potassium content initially decreased and followed by an increase.After rotation,the minimum value of soil available potassium content was 260.44mg/kg,which was in a potassium-rich state.Consequently,the introduction of alfalfa into the grain farming system in the desert area of northern Xinjiang plain can effectively improve the soil organic matter content, increase the total nitrogen storage and reduce the salinity.However,in the fourth year of alfalfa growth,nitrogen and phosphorus fertilizer should be appropriately supplemented,but with no need for the addition of potassium fertilizer.
