| 摘 要： | 结合饶阳县万亩综合防护林体系建设,笔者于1984～1985年进行了开沟造林技术的研究,结果表明林木成活率达93％以上,林木总生物量(造林后2.5 a)是不开沟造林的1.6倍,同时改善了土壤的水分、养分状况和林木叶片养分含量,为干旱瘠薄的沙地造林开创了一条新途径。

| Abstract: | In the build-up of the comprehensive shelter fosest system in Rao-yang county,the techniques of trench afforestation were used and studied during 1984 and 1985.The results showed that the survival rate of the trees could be higher than 96%, and the total biomass accumulated in 30 months after afforestation was 1.6 times higher than that of non-trenched. Meanwhile, trench afforestation improved the soil moisture, nutrient status and nutrient content in leaves. Therefore, trench afforestation proved to be a new efficient way for arid and poor sandy land. |
