- 摘要:
- 为寻求降低林地土壤蒸发量的经营措施，以江都地区6 a生女贞人工林为例，研究了稻草、枯落物、石砾覆盖以及50%和70%强度移植对其土壤含水量季节动态的影响，以及含水量与毛管孔隙度、温度等关系。结果表明：覆盖增加土壤表层含水量，4，11月稻草覆盖的保水效果最好，7月枯落物覆盖的保水效果最好，石砾覆盖缩小各土壤层间含水量差异。随移植强度增大，覆盖对表层土壤含水量的增加效果减弱，土壤保水性降低。研究可为建设节水型绿地提供一定的科学依据。
- Abstract:
- An experiment was conducted to study the interactions between capillary porosity, temperature and moisture, and the seasonal effect of four treatments including straw, mulching litter mulching, gravel mulching and open ground on forest soil water content among three different densities(50%, 70% transplanting and without transplanting) in 6-year-old Ligustrum lucidum Ait. plantation in Jiangdu in order to determine the optimal management strategies to reduce the water consumption of urban green space. Result showed that mulching treatments increased water content of surface soil. Among these treatments, straw mulching was the best in April and November, while litter mulching was the best in July; compared with the control plots, gravel mulching reduced the soil moisture differences between different soil layers. With the increase of transplanting strength, the enhancement effect of mulching treatments on surface soil was weak and soil water holding capacity decreased.
