中文摘要：

以玉米清种、沙打旺清种、玉米/沙打旺间作（2∶1）、玉米/沙打旺间作（4∶2）、玉米/沙打旺间作（2∶2）为例研究不同间作模式的土壤水分和产量效应。结果表明：玉米/沙打旺间作对土壤水分时空变化有一定的影响,土壤水分季节性变化趋势明显,从上到下,随土层深度增加,土壤含水量均表现出＂先增大,后减小＂的趋势。玉米/沙打旺间作对玉米株高的影响不显著,而对沙打旺的株高影响显著,同时株高的差异改变了玉米的通风透光状况。玉米、沙打旺间作（4∶2）可以影响玉米干物质积累速率并延长峰值出现的时间,使其保持较长的快速增长期。玉米产量性状中,穗长、穗粗、行粒数、行数和轴粗各处理间差异不显著,而百粒重达到了显著性差异,产量也达到了极显著差异,以玉米清种最大,为15 567.50 kg/hm^2,以玉米/沙打旺（2∶1）的产量最低,为11 238.33 kg/hm^2。综合来看,玉米/沙打旺间作（4∶2）模式可以在辽西地区推广种植。

英文摘要：

An experiment was conducted to study the effect of maize and erect milkvetch interplanting on soil moisture and yield throuth pure maize planting,pure erect milkvetch planting,maize/erect milkvetch interplanting（2∶1）,maize/erect milkvetch interplanting（4∶2）,and maize/erect milkvetch interplanting（2∶2）.The results indicate： The maize/erect milkvetch interplanting has certain influence on spatial and temporal changes of soil moisture,and the seasonal change tendency of soil moisture is obvious,from top to bottom,increasing along with the soil layer depth,and the soil moisture content displays a tendency of ＂increasing first and then decreasing＂.The maize/erect milkvetch interplanting dose not have remarkable influence on maize height,but has remarkable influence on the height of erect milkvetch,while the difference of plant height changes the maize＇s aeration and photopenetration conditions.The maize/erect milkvetch interplanting（4∶2） may affect the dry matter accumulation speed of maize and prolong the peak time thus maintain a longer period of fast growth.For the maize yield characters,the length and diameter of ears,grain number per row and row number are not much different under various treatments,but 100-grain weight is significantly different,and the yield achieves extremely remarkable difference,of which the greatest is pure maize planting,as much as 15 567.50 kg/hm^2,while that of maize/erect milkvetch interplanting（2∶1） is the lowest,as low as 11 238.33 kg/hm^2.As a whole,the pattern of the maize/erect milkvetch interplanting（4∶2） may be extended in west Liaoning area.
