针对日光温室随种植年限增加,土壤质量退化的问题,研究了5种不同的农艺处理措施对土壤酶活性的影响.结果表明,食用菊花和番茄轮作、番茄嫁接2个处理对提高不同土壤酶活性的效果显著;夏季石灰氮消毒处理对提高脲酶、磷酸酶和过氧化物酶活性的效果显著;夏季填闲大葱对前季作物土壤酶活性的影响大于后季作物.番茄产量与土壤酶活性的变化趋势基本一致.蔗糖酶、脲酶、磷酸酶、多酚氧化酶和过氧化物酶可以作为设施蔬菜敏感的土壤酶学指标.在难以进行轮作的以番茄生产为主的地区,采取嫁接栽培能有效提高土壤酶活性;在有条件轮作地区,采取食用菊花与番茄轮作,对提高土壤酶活性和栽培效益方面有积极作用.

To solve the problem of soil degradation with the increase of continuous cropping years in the solar greenhouse, changes of soil enzyme activities under five different agricultural treatments were studied. The results suggest that the soil enzyme activities are increased significantly under the rotation between vegetable chrysanthemum and tomato, and grafting tomato treatments. Soil urease, phosphatase and peroxidase activities are increased significantly as well under the calcium cyanamide treatment in summer. Cultivating welsh onion in summer, the soil enzyme activities in autumn are significantly higher than that in spring. The tomato yield coincides with activity variation of soil enzymes, this indicates that sucrase, urease, phosphatase, polybenoloxidase and peroxidase can be used as sensitive biological indices for vegetable cultivation in greenhouse. In the region in which crop rotation is difficult, grafting cultivation can be used to increase soil enzyme activities, while, the rotation between vegetable chrysanthemum and tomato can play a positive role in maintaining soil enzyme activities and cultivation efficiency when the crop rotation is available.
