摘 要:本文对不同种植年限日光温室的土壤活性有机质和腐殖质组成进行了研究,发现随温室种植利用年限的增加,日光温室土壤有机质、腐殖质和活性有机质质量分数均呈升高的趋势。日光温室土壤活性有机质质量分数增幅大于有机质总量的增幅,高龄日光温室0~<20 cm,20~<40 cm土层活性有机质占有机质比例均在20%以上,高于温室外粮田0~<20 cm的表层土壤。随种植利用年限的增加,日光温室土壤中松、稳、紧各级结合态腐殖质质量分数均呈增加的趋势;其中松结合态腐殖质占比大于粮田,稳结合态和紧结合态腐殖质占比小于粮田。日光温室土壤松结合态腐殖质与紧结合态腐殖质的比值(即松紧比)均大于粮田土壤。Through the study of soil active organic matter and humus composition in different planting years,the results showed that the soil organic matter,humus and active organic matter content in solar greenhouse increased with the increase of planting years.The increase of soil active organic matter content in solar greenhouse was greater than the increase of total organic matter,and the proportion of active organic matter in soil layer above 40 cm was more than 20%,which was higher than that of grain field outside greenhouse in 0~<20 cm soil layer.The content of loosely,stably and tightly combined humus increased with the increase of planting years in the soil of solar greenhouse.Among them,loosely combined humus proportion was greater than grain field,stably combined humus and tightly combined humus proportion were less than grain field.The ratio of loosely combined humus to tightly combined humus(loose compact ratio) in solar greenhouse soil was greater than that in grain field soil.
