Soil moisture among plants and in rows of the close planting Jujube forest in the loess hilly and gully region
摘要
Abstract
In order to reveal the characteristics of spatial distribution of soil moisture in the close planting Jujube forest in Northern Shaanxi Province, continuous monitoring of soil moisture in 0 ~ 200 cm soil layer was carried out in different positions (inter-tree, inter-row and center-point) of the Jujube forest. The results indicated that soil moisture of inter-tree was significantly better than inter-row in July ~ September. The average soil water of inter-tree, inter-row and center-point was 9.77% , 7.66% and 7.52% . With the changing of rainfall, cumulative infiltration was different in various positions of the Jujube forest. The infiltration^ capacity of inter-tree was larger than that of inter-row. With the increase of rainfall, the infiltration capacity increased in all positions and the infiltration was recharged. The function in inter-tree increased, but that in inter-row decreased. For example, in the moderate rain (p - 14.8 mm) , the infiltration capacity of inter-tree, inter-row and center-point was 15.5 mm, 8.8 mm and 8.4 mm; while in the heavy rain (p -31.6 mm), that was 30.9 mm, 16.5 mm and 12.8 mm, respectively. The average daily consumption of soil water in inter-tree was the highest (4.09 mm/d) , followed by that in inter-row (3 .77 mm/d) , and that in center-point was the lowest (2.77 mm/d) in all positions.关键词
