现代设施农业中香石竹根区土壤生物酶因子时空变化研究

Temporal and Spatial Changes of Soil Enzyme Factors in Carnation Rhizosphere under Cultivation

[目的]为了对香石竹病害监测、预防方面提供一些基础理论依据。[方法]通过定位监测,研究香石竹种植区正常株与发病株根际土壤酶活性的时空变化特征。[结果]土壤酶活性变化与土传病害发生具有一定的关联性。[结论]多酚氧化酶、磷酸酶、脲酶可以作为预测、指示土传病害发生的表征,脱氢酶、木聚糖酶也可以作为夏季预测、指示土传病害发生的表征。

[Objective]The research aimed to provide the basic theoretical reference for the disease monitoring and the protection of the carnation.[Method]Through point monitoring,temporal and spatial variation of soil enzyme activity in rhizosphere soil of normal plant and incident plant were studied.[Result]Changes of the enzyme activity in the soil associated with soil-borne disease occurred.[Conclusion]Polyphenol oxidase,phosphatase,urease could be used as the instructions for forecasting the occurrence of soil-borne diseases.Dehydrogenase,xylanase could be used as the instructions for forecasting the occurrence of soil-borne diseases in the summer.
