摘　　要：青海省大部处于干旱、半干旱地区,保持土壤水分、提高树木成活率成为造林关键问题。在樟子松、云杉等树种造林中应用集雨托盘进行抗旱造林对比试验,结果表明:覆盖集雨托盘显著提高了北山林场云杉幼树树高和冠幅的生长及其存活率、高生长率、冠幅生长率;覆盖集雨托盘显著提高了平安县油松幼树当年高生长量及其生长率和存活率;覆盖集雨托盘显著提高了大通县樟子松苗木树高生长量、存活率和高生长率;覆盖集雨托盘显著性提高了都兰县枸杞苗木冠幅生长量,提高了其冠幅生长率和存活率。Most of Qinghai Province is in the condition of arid and semi-arid,the annual rainfall is few,and the evaporation is large.So how to keep the soil moisture and improve the survival rate of afforestation has become a very dangerous problem.This study is based on the rainwater collection tray developed by Qinghai Futeng Ecological Technology Co.,Ltd.as a test material and carries out a comparative experiment to get optimal measures for drought resistant afforestation.Result shows that:Rainwater collection tray significantly improved the growth of tree height and crown of Picea spp.in Beishan Forest Farm,and significantly increased its survival rate,high growth rate and crown growth rate;the cover of rain tray significantly improved the annual high growth of Pinus tabulaeformis in Ping’an County,and increased its high growth rate and survival rate,while covering rain pallet significantly increased the high growth rate of Pinus sylvestris seedlings in Datong County,and increased the survival rate and high growth rate;covered rainwater tray significantly increased the crown growth of wolfberry seedlings in Dulan County,and increased its crown growth rate and survival rate.
