- Abstract:
-
By the method of field investigation and laboratory analysis, the characteristics of soil physical-chemical properties and enzyme activity were studied to the abandoned cropland. The results showed that: (1) The content of soil grain grade ranking from small amount to much was powder viscous grain>physical viscous grain>viscous grain, and the amount of the three kinds of grain in the loquat garden were all more than those under the other conditions. (2) The content of soil organic matter rank was fir plantation>eucalyptus plantation>loquat garden>tea garden>abandoned land. The cation exchange capacity was eucalyptus plantation>loquat garden>tea garden>abandoned land>fir plantation, but there were no significant differences between different land uses. The total nitrogen content ranking from small amount to much was abandoned land>loquat garden>tea garden≥fir plantation>eucalyptus plantation, the total phosphorus content rank was fir plantation>tea garden>abandoned land>loquat garden>eucalyptus plantation, the total potassium content rank was loquat garden>eucalyptus plantation>tea garden>abandoned land>fir plantation. (3) The activity of catalase ranking from strong to the weak was fir plantation>abandoned land>loquat garden>tea garden>eucalyptus plantation. The activity of urease in abandoned land and loquat garden was stronger, and the differences between the two were very obvious. The activity of alkaline phosphatase in abandoned land was the strongest while the tea garden’s was the weakest, and the activity of the acidic phosphatase rank was fir plantation>eucalyptus plantation>loquat garden>abandoned land>tea garden. (4) The change trend of soil quality comprehensive index was fir plantation>eucalyptus plantation>tea garden>loquat garden>abandoned land.
