摘要
沙区气候环境条件恶劣,特别是近年气候变化异常,致使沙区造林成活率较低。试验得出:整地比未整地地块造林成活率提高17.09个百分点;整地秋季埋根造林比翌年春季植干造林成活率提高6.3个百分点;未整地秋季埋根造林比翌年春季植干造林成活率提高9.3个百分点;实施林农复合经营是非常有效的一种抚育方式;采伐迹地造林,整地是造林成败的关键环节,通过农事活动整地,可及时清除伐根,改善地力。
Unusual climate results in lower afforestation survival rate in sandy area. Afforestation survival rate under soil preparation is 17.09% higher than that under non-preparation soil.Suvival rate under planting by root in autumn is 6.3% higher than that under planting by stem in the next year under soil preparation. Planting by root in autumn improves 9.3% more than that of planting by stem under non-preparation soil. Agroforestry is an effective tending means. Soil preparation is the key of improving afforestation survival rate,for it cleans up stumps and raises soil fertility.
