吉林省西部耐水湿、抗盐碱水田防护林树种优选
Optimized Selection of Tree Species for Shelter Belt of PaddyField on Waterlogging Tolerant Trees and SalinizationResistance Trees in West Jilin
摘要
Abstract
14 trees (varieties) including Populus×canadensiscv.'Serotina' and Populuspsedosimonii×nigracv'Baicheng',etc.were taken as the studied objects.Through consistently investigating and analyzing the cuttings survival rate,afforestation survival rate,preservation rate and the growth,the suitable tree species were optimally selected from the 14 species for the water resistance and alkali resistant paddy soil in the west of Jilin province.The cutting experimental results showed that,of the 14 species,the Populuspsedosimonii×nigracv'Baicheng',(P.psuedo-simonii×P.nigra)×P.euramericanacv.,'heilin3',Salix limprichtii,Ulmuspumila,and salix×'Chuibao109'were of higher cuttings survival rate of 86.1%,86.3%,90.4%,90.9%and 97%,respectively.It was indicated,by further observation of tree height and diameter growth index of the five species,that the Salix limprichtii growth performance was relatively poor,of the annual height growth and diameter growth only 0.73m and 0.84cm,respectively,which had significant difference with other species.After afforestation,the growth of Populuspsedosimonii×nigracv'Baicheng',P.×"Bailin-3",Ulmuspumila and salix×'Chuibao109' were observed.The observation results showed that,the survival rate of P.×"Bailin-3" was only 86%,significantly different from other tree species.Hence,Populuspsedosimonii×nigracv'Baicheng',Ulmuspumila and salix×'Chuibao109'were water and alkali resistance,and were demonstrated to be the most suitable tree species for shelter belt of paddy field in Western Jilin.关键词
