摘要
通过对榆林毛乌素沙地樟子松林地沙层水分状况的测定 ,以及对樟子松不同造林密度试验研究表明 :造林密度与沙层水分状况密切相关 ,提出榆林毛乌素沙地樟子松造林的适宜密度为 5 6株·6 6 7m-2 ,即造林株行距为 3m× 4m。
By determining water of sand land of inus sylvestris Linn.var.mongolica Litv.in Yulin Maowusu desert and studying different afforestaion densities of Pinus sylvestris Linn.var.monglica Litv.,the result showed that the afforestaion density of Pinus sylvestris Linn.var.mongolica Litv. was relative with water of sand land closely,and the fittest afforestaion density in Yulin Maowusu desert was 56 trees·667 m^(-2)(i.e.3 m×4 m).
