西藏阿里地区沙地柏引种栽培技术研究

Study on Introduction and Cultivation Techniques of Sabina vulgaris in Ali Area,Tibet

通过土地整理和土壤改良,设置了保水、混交和覆土越冬对比试验,系统开展了引种地和试验区对比研究,对沙地柏成活率、保存率、生长情况进行了分析。结果表明:存活率表现为保水处理组(90.99%)>混交处理组(87.39%)>对照组(74.09%),生长量表现为保水试验组(5.13 cm)>混交处理组(4.77 cm)>对照组(3.35 cm);经过2年引种驯化,试验区土壤pH较对照组降低了0.09,土壤中有机质含量有所增加。

Ngari area has few vegetation and extremely bad natural environment.In order to improve the local ecological environment,the cultivation experiment of introduction of Sabina vulgaris in Yulin into Shiquanhe area was carried out.the survival rate,growth and soil improvement of Sabina vulgaris were analyzed by setting up water retention comparison test,mixed comparison test and soil covering winter comparison test.At the same time,the climatic factors in Ali area of Yulin were compared and analyzed.the results showed that the law of survival rate was as follows:water retention treatment group(90.99%)>mixed treatment group(87.39%)>control group(74.09%),and the law of growth was as follows:water retention experimental group(5.13 cm)>mixed treatment group(4.77 cm)>control group(3.35 cm);After 2 years of planting,After two years of introduction and domestication,soil pH in the test area decreased by 0.09 compared with the control group,and soil organic matter content increased.
