Abstract:
Variation of microflora and enzyme activity in solar greenhouse soil continuous cropping for 1, 3, 5, 7, 9 years was studied, in addition to the relationship between soil properities and microflora and enzyme activity. The results showed that number of bacteria, actinomyce as well as total microflora showed a trend with a saddle-shaped curve, while the number of fungi appeared an liner increase. Continuous cropping soil microflora shifted from bacteria type to fungi type significantly, of which Ammoniation bacterium and Fusarium oxysporum were main physiology groups. Path analysis results showed that microelements (Mn, Cu, Fe), organic matter, available N and bulk density are main restricted factors of soil microflora and enzyme activity in solar greenhouse.
