大连岩质海岸黑松造林关键技术综合运用及效果

通过在大连岩质海岸进行黑松造林试验研究,结果表明:采用春季内顷斜面集雨小坑整地和等高梯面扬角平台整地方式,采用容器苗雨季雨前分片造林等综合造林技术措施,可获得较好的造林效果,造林成活率达到86.37%~87.9%,而对照造林成活率为65.4%~71.8%。该综合技术提高造林成活率明显。

Integrated Use and Effect on the Key Technologies of Pinus thunbergii Afforestation in Rocky Coast of Dalian City

Experiments of Pinus thunbergii afforestation in the rocky coast of Dalian City were conducted.Result shows that optimal afforestation effect can be obtained by land preparation methods with a small pits in inward tilt for collecting rainwater and a surface platform having angle with outside high and inner low angle and integrated technologies of afforestation by using container-seedlings before a rain in rainy season;the survival rate is from 86.37%to 87.9%,while the CK is from 65.4% to 71.8%.This integrated technologies can increase the survival rate significantly.
