可降解生态垫是一种新型的苗木培育材料,能有效的减少地面蒸发,控制土壤水分,提高造林成活率。为了检验可降解生态覆盖垫在河滩地造林中对土壤含水量的影响,试验区共设2个处理(有生态覆盖垫、无生态覆盖垫)对降雨后不同时间(1 d、3 d、5 d、7 d)刺槐、油松、元宝枫、蒙古栎、侧柏和铺地柏等林地的土壤含水量进行了调查。结果表明:可降解生态垫抑制地面蒸发效果更为明显;生态覆盖垫对油松林地的保水作用影响最大;阔叶林林地的土壤含水量较针叶林林地小。
Biodegradable ecological pad is a new nursery stock cultivation material, which can effectively reduce the evaporation on the ground, control soil moisture and improve the survival rate of afforestation. In order to test the effect of degradable ecological cover pad on soil water content in riverbank afforestation, a total of two treatments (with ecological cover pad and no ecological cover pad) were conducted to evaluate the effects of degradable ecological cover pad on soil water content at different times after rainfall (1 d, 3 d, 5 d, 7 d) Soil moisture was measured in the forest land of Robinia pseudoacacia, Pinus tabulaeformis, Acer truncatum, Quercus mongolica, Platycladus orientalis and Pterodendron chinense. The results showed that the biodegradable ecological pad was more effective in inhibiting ground evaporation. The ecological pad had the greatest effect on the water retention of Pinus tabulaeformis woodland. The soil water content of broad-leaved forest was less than that of coniferous forest.
