摘要
Abstract
The soil at different position and depth of root-range in litchi orchards of Guangliang town was selected to analyze the urease activity and the relation between it and soil agrochemical property and litchi yield. The results indicated that the urease activity in high-yield litchi orchard was notably higher than that in low-yield orchard. The urease activity had significant positive correlation with the nutrient content. The urease activity in soil had some regularity:It was the highest at the radius of tree crown in its level distribution area,and inward or outward it decreased gradually;The urease activity in the soil at 0-20cm depth was the highest in its vertical distribution,and it decreased gradually with the depth increasing.关键词
