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。
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 ma terials 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.
