摘要
在黑龙江省半干旱地区通过全面整地、开沟整地、穴状整地和不整地对樟子松、云杉、落叶松和银中杨的造林成活率、保存率以及树高和地径生长量影响的试验研究,结果表明:开沟整地可大大提高针叶树的造林成活率和保存率,同时可有效提高樟子松和云杉的林木生长量。
Through the whole, pits, holes land preparation in semi-arid area in Heilongjiang Prov. on the effect of survival, preserving rate , growth increment of tree height and DBH, the results showed that pits land preparation could increase the forestation survival and preserving rate, and could increase effectively the growth of Pinus sylvestris vat. mongolica and Picea asperata .
