中文摘要	在河西灌区灌漠土上连续种植制种玉米2、4、6、8、10a的地块为标准样品采集区，取0～20cm耕层土样30个室内化验分析土壤理化性质。研究结果表明：随着玉米种植年限的延长，土壤孔隙度、碱解N、速效P、可溶性盐含量在递增，二者呈正相关。土壤容重、速效K随着玉米种植年限的延长在递减，二者呈显著的负相关。种植玉米2～8a土壤有机质含量虽然随玉米种植年限的延长而增加，但增加的幅度不大，种植玉米10a后，土壤有机质表现出下降的趋势。土壤pH随着制种玉米种植年限的延长而降低，连续种植玉米10a土壤pH任趋于中性，不会对土壤理化性质产生不良的影响。
英文摘要	The plots of standard samples were selected in irrigated desert soil of Hexi irrigation area with continuous plantation of maize for 2,4,6,8 and 10 years.30 soil samples in 0-20 cm plow layer soil were analyzed for physical and chemical properties in laboratory.The results showed as follows.With the extension of maize planting years,soil porosity and the contents of alkali N,available P and soluble salt gradually increased and positively correlated with plantation time However,soil bulk density and available K gradually decreased and showed a negative correlation with plantation time.The soil organic matter content under 2-8 years’ of plantation increased with slight degree but showed a downward trend after 10-year plantation.The pH of soil decreased with the increase of plantation time and became neutral after 10-year plantation which had no negative impact on the soil physical and chemical properties.
