乌兰布和沙漠东北部覆膜对杨树苗期土壤水热变化及成活率的影响
Effects of Plastic Film Mulching on Soil Water and Heat Changes and Survival Rate of Poplar Seedlings in Northeast of Ulan Buh Desert
摘要
Abstract
[Objective]To study the influence factors of survival rate of protection forest tree species in the northeast of Ulan Buh Desert.[Method] Afforestation with plastic mulching in northeastern Ulan Buh Desert,the effect of single film covered,two sides covered with film,uncovered on the soil moisture content,soil temperature,survival rate,preserving rate,growth index.[Result]The results showed that the soil moisture content of different mulching methods showed an upward trend with the increase of soil depth,soil water content from large to small followed by two sides covered with film,single film covered,CK.After watering for 15 days,in the 0-10,10-20,20-30,30-40,40-50 and 50-60 cm soil layers,the soil moisture content of film mulching increased by 43.6％,34.6％,32.9％,25.8％,18.0％ and 7.1％,respectively.Soil temperature from large to small followed by two sides covered with film,single film covered,CK.5,10,15 and 20 cm soil layers on two sides covered with film were increased by 0.9,0.8,1.1 and 0.8 ℃,respectively.Survival rate and preserving rate from large to small followed by two sides covered with film,single film covered,CK.New shoot increment from large to small followed by two sides covered with film,single film covered,CK.[Conclusion] It was suggested that afforestation with plastic mulching can be considered to use in northeastern Ulan Buh Desert.关键词
