| 摘 要： | 从2004年到2006年,通过3 a对沙地云杉2 a、3 a和4 a生苗木的田间座水覆膜试验,结果表明:座水覆膜可以明显地提高土壤温度,抑制土壤水分蒸发。土壤温度平均提高2℃,土壤含水量平均提高1.87%~2.36%。2 a、3 a和4 a生苗木造林成活率比对照分别提高25%、21.4%和23.8%,苗木高生长量比对照分别提高26%、44%和22%。

| Abstract: | From 2004 to 2006,the nursery stock of picea mongolica of 2-,3-,and 4-year old were used in watering and covering film experiment for three years.The result indicates: Watering and covering film enhance soil temperature obviously,and suppression soil moisture evaporation.Soil temperature increases two degree in average,the soil moisture content increases 1.87% to 2.36%.The survival rate of 2-,3-,and 4-year old nursery stock increases 25%,21.4% and 23.8% compared with the control,the grourth rate in creases 26%,44%,and 22% respetively compared with the control. |
