黑龙江西部低山丘陵坡面集水工程抗旱造林试验

Experiments of Anti-arid Afforestation Based on Slopes Catchment Project in Western Hilly Area of Heilongjiang Province

选取4种不同的坡面集水处理(覆膜、撒水泥、刨光、自然坡面)措施,开展了不同坡面集水措施对造林效果影响的试验。结果表明:不同坡面处理措施对土壤含水率、造林成活率及林木生长产生不同影响,其中撒水泥处理措施土壤含水率最高,覆膜处理措施造林成活率最高,且苗木生长效果最好。

Selecting four different slope catchment measures （film, spreading cement, planed, natural slope）, experiments of influences of different slope catchment measures on afforestation effect were carried out. Result shows that., different slope measures produce different effects on soil moisture content, survival rate of afforestation and forest growth, among which soil moisture are the highest by using spreading cement ; survival rate of afforestation are the highest by using film treatment and the effect of seedling growth are the optimal.
