| 摘 要： | 经过连续多年采用不同的整地方式、不同造林密度、不同覆盖保水对辐射松(Pinus radiataD.Don)造林及幼林生长的试验研究,结果表明:(1)干旱地带采用水平沟、短册状整地比穴状整地造林成活率提高2.4~7.8个百分点,保存率提高1.0~7.6个百分点,高生长量提高7.8 cm~28.4 cm,地径生长量提高0.28 cm~0.84 cm。(2)水平沟整地比短册状、穴状整地0~100 cm土壤层含水量全年分别提高1.29个百分点和2.08个百分点,旱季分别提高1.36个百分点和1.37个百分点,雨季分别提高1.16个百分点和2.87个百分点;短册状整地比穴状整地0~100 cm土壤层含水量全年提高0.80个百分点,旱季提高0.01个百分点,雨季提高1.72个百分点。(3)采用1.5 m×2.0 m造林密度,短册状或水平沟整地,采用石块、塑料薄膜覆盖,造林成活率达96%,保存率达90%。 |

| Abstract: | Afforestation experiments of Pinus radiata D.Don were conducted with different kinds of site preparation and the young growths for years.The results showed as follows：（1）The survival ratio of the Pinus radiata plantation planted in arid areas increased by 2.4%~7.8% than the control and its conservation ratio increased by 1.0%~7.6%.Its height increment was 7.8 cm~28.4 cm higher than the control and its ground diameter increment was 0.28 cm~0.84 higher.（2）The preservation ratio of the plantation,the moisture content in soil of 0~100 cm in depth increased respectively by 1.29% and 2.87% than the control in all years,the moisture content in soil of 0~100 cm in depth increased by 1.36% and 1.37% than the control in the dry season and increased by 1.16% and 2.87% in the rain season;the moisture content in soil of 0~100 cm in depth increased by 0.80% than the control in all years.The moisture content in soil of 0~100 cm in depth increased by 0.01% than the control in the dry season and increased by 1.72% in the rain season.（3）The survival and preservation ratios of the plantation planted with rocks or plastic membranes covering,site preparation of level trenches and 1.5 m×2 m of planting density were 96% and 90% respectively. |
