开展了不同初始定植密度和培育管理措施对祁连圆柏(Sabina przewalsbii Kom.)绿化大苗树形和经济效益的试验,结果表明:采用5a祁连圆柏实生小苗培育2m高的绿化大苗,初次定植密度应以0.6m×0.8m的株行距为宜,生长5a后实行隔行整行和保留行隔株带土球移植,从初次定植后每年进行整形修剪,可使II级以上优质苗达到78%,且经济效益高;2m高的祁连圆柏在起苗时土球大小以直径为50cm、厚度为40cm为宜,确保在各种立地条件下造林成活率达到90%以上。
Experiments were conducted on the tree shape and economic benefits of Sabina przewalsbii Kom. Seedlings with different initial planting densities and cultivation management measures. The results showed that the initial planting density of 5 m 0.6m × 0.8m line spacing is appropriate, the growth of 5a after the implementation of interlaced lines and retention lines with soil ball earth graft, from the initial planting after each annual pruning, can make quality class II above 78%, and the economy The 2m high Sabina przewalskii seedlings in the diameter of 50cm when the soil ball diameter, thickness 40cm is appropriate to ensure that in a variety of site conditions afforestation survival rate of more than 90%.
