辽西干旱丘陵区竹节壕整地方式对油松移植苗造林质量的影响

Effects of Site Preparation of Bamboo-trenches on Afforestation Quality of Pinus tabulaeformis in Arid Hilly Area of Western Liaoning Province

造林成活率不高一直以来对辽西干旱丘陵区植被的重建及恢复有很大的影响。为解决这一问题,试验研究了竹节壕整地方式对油松移植苗造林质量的影响。结果表明,通过在造林前进行竹节壕整地,对土壤含水量及造林成活率均有明显的影响,与未整地的处理相比,土壤含水量增加了53.55%~74.48%,造林成活率平均提高28.94个百分点。

In order to solve this problem, the effect of bamboo trench preparation on the quality of Pinus tabulaefor- mis seedlings was studied in this experiment. Result shows that soil moisture content and afforestation survival rate were significantly affected by soil tarton preparation before afforestation. Compared with untreated treatment, the water content in soil increase by 53. 55%-74. 48% ;the survival rate increase by 28. 94%.
