Effects of saline water irrigation on plants growth of the Tarim Desert Highway shelter-belt
摘要
Abstract
Afforestation experiment under saline water irrigation of different mineralization in Xiaotang, and location investigation of the shelter％ belt along the Tarim Desert Highway under saline water irrigation of different mineralization were done. Survival rate, height, crown width, ground diameter, aboveground biomass, seed setting condition,and such conventional growth index were selected. Effects of saline water irrigation of different mineralization on growth conditions of Haloxylon ammodendron , Calligonum arborescons , and Tamarix ramosissima under was analyzed and compared. The results show that the mineralization of irrigation water had significant effect on germination and survival, vegetative growth ,and seed setting of 3 plants,meanwhile ,integrative manifestation was inhibition with rising of irrigation water mineralization, and there is nearly relationship between salt stress and the threshold of irrigation water mineralization. Haloxylon ammodendron had no seed setting when mineralization was above 20 g/L,but survival and growth almost were not affected. The survival threshold of Calligonum arborescons and Tamarix ramosissima was 15 -20 g/L,and salt-resistance thresholds were about 15 g/L and 20 g/L. The sequence of salt-resistance ability of 3 plants was Haloxylon anmodendron, Tamarix ramosissima and Calligonum arborescons.关键词
