| 摘 要： | 采用地膜和杂草覆盖造林,平均成活率比对照分别提高25%和9%;地膜规格以30 cm2为宜;杂草覆盖面积以60 cm2、厚10 cm2为好。侧柏覆膜造林的生长进程一直高于对照,3~4月生长较快,4~8月生长中庸,9月以后生长缓慢,10月初停止生长。不同土层含水量为:5 cm层平均提高了30.6%,10 cm提高了23.4%,15 cm提高了10.6%。不同土层温度的变化趋势为,5 cm层较对照提高了12.2%,10 cm层提高了8.7%,15 cm层提高了4.1%,30 cm层提高仅1%。

| Abstract: | Afforestation with mulch produces a higher survival rate,25% and 9% over the contrasts respectively.The scale of polyfilm is preferably 30cm2 and covering straw 60Cm2 and 10cm thick.The techniques produced better effects on the growth of cypress over the contrast, with fastest growth during March and April,moderate during April to August,and slowest in September and a cease of growth in October.The soil moisture in 5cm deep is is increased by 30.6%,10cm deep by 23.4% and 15cm deep by 10.6%.Under the same condition,the temperatures in different depths of soil tend to be higher than the contrast,12.2% over the contrast for 5cm deep of soil,8.7% over for 10cm deep soil,4.1% over for 15cm deep soil and only 1% over for 30 cm deep of soil. |
