摘　　要：一些大棚蔬菜集中种植区,有大量用过的蔬菜栽培基质被废弃而成为农业垃圾。本试验利用这些废弃基质通过蒸汽处理或加杀菌剂等方式将其做为土壤调理剂再利用。通过盆栽和大棚种植油麦菜试验证明:施入调理剂处理的油麦菜株高较CK增加53%~210%,产量提高3~11倍;在土壤效应方面,施入调理剂的土壤pH值较CK降低,土壤容重明显降低,孔隙度明显增加,养分显著增加,有机质增加13.8%~39.9%,碱解氮增加12.5%~30.9%,有效磷增加16.5%~42.6%,速效钾增加12.5%~36.8%。说明用废弃基质制作大棚土壤调理剂是可行的,其中,用蒸汽处理废弃基质是较好方法。In some greenhouse vegetable planting areas,a large amount of used vegetable cultivation substrates have been abandoned and become agricultural wastes.In this study,the waste matrix was reused as soil conditioner by steam treatment or adding fungicides.The results of potted and greenhouse cultivation experiments showed that compared with the control the plant height of lettuce increased by 53%~210%,and the yield of lettuce increased by 3~11 times respectively.In terms of soil improvement effect,the soil pH of the treatment with conditioner was lower than that of the control.Soil bulk density decreased obviously,while porosity increased obviously.Soil nutrients increased significantly,including organic matter 13.8%~39.9%,alkali-hydrolyzable nitrogen 12.5%~30.9%,available phosphorus 16.5%~42.6%,and available potassium 12.5%~36.8%.It was feasible to produce soil conditioner with waste matrix in greenhouse especially the steam treatment.
