| 摘 要： | 通过在辽西北半干旱石质山区进行不同材料覆盖保墒造林试验研究,结果表明:覆盖对土壤温度的调节因覆盖材料的不同而表现出不同的效果——地膜覆盖能提高土壤温度,覆草和覆石均降低土壤温度;造林后覆盖,土壤平均含水率比对照提高0.39%～2.34%,覆草效果最好;不同覆盖材料均能提高大部分树种的造林成活率,以覆草效果最好,覆膜次之。

| Abstract: | Afforestation experiments with different materials were conducted in semiarid rocky mountain in western Liaoning.Result shows that adjust of mulching on soil temperature show different effect with different mulching materials-mulching can increase soil temperature;straw mulching and stone mulching all decrease soil temperature;the mean moisture content of soil mulching after afforestation increase by 0.39%-2.34%,the straw mulching being the optimal;different mulching materials could improve the afforestation survival rate of most tree species;the effect of straw mulching is optimal,film mulching followed. |
