针对山区植树造林过程中供水困难,苗木栽植后成活率和生长量难以提高等问题,设计一种雨水收集器(本设计一种雨水收集器已获实用新型专利,专利号201420788151.3),可有效收集降雨和降雪,为树木地下根系及时提供和储备水分,有效提高山区雨水和雪水的利用率及苗木成活率和生长量。通过试验结果表明:该种雨水收集器促进水分下渗,改变不同月份和不同深度土壤相对含水量,为栽植的祁连圆柏(Sabina przewalskii)收集雨水后成活率、树高和冠幅较常规树坑浇水和树坑集雨分别提高了14.7个百分点、11.3cm、14.2cm和35.2个百分点、16.8cm、18.7cm,差异均达到了极显著水平。
Aiming at the problems such as water supply difficulties, survival rate and growth rate after seedling planting in mountainous area, a rainwater collector was designed (a rainwater collector designed with utility model patent No. 201420788151.3) which can effectively collect Rainfall and snowfall provide timely supply and reserve of water to underground roots of trees and effectively improve the utilization of rainwater and snow water and the survival rate and growth rate of seedlings. The results show that the rainwater collector can promote the seepage of water, change the soil relative water content in different months and different depths, and the survival rate of the collected Sabina przewalskii rainwater is higher than that of the conventional tree pit Watering and rainstorms increased by 14.7 percentage points, 11.3 cm, 14.2 cm and 35.2 percentage points, respectively, reaching 16.8 cm and 18.7 cm respectively, reaching significant levels.
