采用随机区组试验设计,分别在土壤含盐量、含水量及降水量不同的环境条件下,进行了浇水造林、不浇水造林及不浇水覆膜造林试验研究。方差分析结果表明,不同处理方法,造林成活率无显著差异,而环境条件不同,成活率差异极显著。通过3年造林试验和推广应用,采用不浇水造林技术,土壤含盐量0.70％、0.85％时,造林成活率分别为95％和86％;含盐量在0.7％～1.01％范围内,成活率平均为82％。造林当年平均地径6.3mm,平均树高63cm,主根长达1.20m。认为柽柳不浇水造林技术具有实用性和可行性,可在沿海地区重盐碱地上大面积推广应用。
Using randomized block design, the experiment of watering and afforestation, afforestation without afforestation and afforestation without afforestation were carried out under different soil salinity, water content and precipitation. Analysis of variance showed that there was no significant difference in afforestation survival rate between different treatments and different environmental conditions, with significant difference in survival rate. Through 3 years of afforestation experiment and popularization and application, using non-irrigated afforestation techniques, the survival rates of afforestation with soil salinity 0.70% and 0.85% were 95% and 86% respectively; the salinity ranged from 0.7% to 1.01% The average survival rate was 82%. The average diameter of afforestation 6.3mm, the average tree height of 63cm, the main root length of 1.20m. That tamarisk irrigated afforestation technology is practical and feasible, can be widely used in heavy saline land in the coastal areas.
