【摘要】 为了研究和筛选沙地柏在黄土丘陵沟壑区的造林关键技术,在安塞县采用正交试验设计等方法设计造林。研究结果表明:（1）采用生根粉溶液浸根+保水剂与根部土壤混合处理时,沙地柏造林成活率、保存率最高,分别达到100.00%、98.45%;（2）抗旱造林技术的优组合为:50×10^-6生根粉溶液浸根、20 g保水剂与根部土壤混合和秸秆覆盖造林穴坑;（3）在沙棘林下,沙地柏造林成活率、保存率可以达到较高水平,分别为99.04%和95.74%,但生长量显著低于荒草地。更多还原

【Abstract】 In order to study and screen the key technologies of Sabina vulgaris afforestation in loess hilly-gully region, afforestation was carried out in Ansai county using orthogonal test design. The results showed that i) the survival rate and preservation rate by the treatment that the root was soaked with 50×10^-6 root powder solution and water retaining agent 10 g and mixed with root soil were the highest, which could reach 100.00% and 98.45 % respectively; ii) the best combination of seedling root treatment and covering treatment is: 50×10^-6 root powder solution soaking root plus 20 g water retaining agent mixed with root soil, and straw covering the pit afterwards; iii) the survival rate and preservation rate of Sabina Vulgaris afforestation in Hippophae rhamnoides forest land can reach 99.04% and 95.74%, respectively, but the growth increment is significantly lower than that of afforestation on grassland.更多还原
