杨树苗木调运中水分散失对栽植成活率和生长量的影响

Effect of evaporation on survival rate and shoot growth of poplar in transportation

通过对比试验研究了新疆杨苗木起挖后不同器官在不同时期水分散失对栽植成活率和新梢生长量的影响。结果表明:苗木不同器官含水量、发芽率、成活率和枝条生长量随着晾晒时间的延长而降低,在不采取任何保护措施的情况下,新疆杨的最佳栽植时期是起挖后6d内。并建议在苗木调运和栽植过程中采用根系蘸泥浆、包裹塑料薄膜、截干和重剪等方法减少根系水分散失,逼迫树干潜伏芽萌发来提高成活率和生长量。

Effects of evaporation on survival rate and shoot growth of xinjiang poplar are studied in different period after digging by contrast test.The result showed that moisture content of different organ,germination percentage,survival rate,and shoot growth are decreased with drying time extended,best planting time of xinjiang poplar is six days after digging with nothing is did.The measures are suggested for increased survival rate and shoot growth,such as roots are dipped in mud and wrapped with plastic film for decreased evaporation in transportation,trunks are cut with saws or clippers for increased germination percentage of latent buds in planting.
