'鲁柽1号'盐碱地造林成活率及生长特性分析OA

To investigate the survival rate and growth conditions of Tamarix chinensis Lour.in saline-alkali land,after surveying the degree of salinity and alkali in Pingluo County,Ningxia,using the'Lucheng No.1'variety as the experimental material,the soil moisture content,survival rate of afforestation,plant height,canopy width,current growth branches,etc.,as well as changes in soil moisture were analyzed.The results showed that the Taole Town area of Pingluo County was a severely saline-alkali area,but the moisture content was relatively high;the Pingluo immigrant area was a moderately saline-alkali area,while the Pingluo forest land wasteland was a slightly saline-alkali area with the lowest moisture content.The survival rate of severely saline-alkali land was the lowest,decreasing by 84.39%compared to the slightly saline-alkali land;the growth indicators of'Lucheng No.1'decreased with the increase in salinity and alkali degree,with a decrease of 17.34%to 37.34%in severely saline-alkali land compared to the slightly saline-alkali land.Through correlation analysis,it was found that salinity was negatively correlated with plant survival rate and growth conditions,and was significantly negatively correlated with survival rate.The above results can provide technical support for the afforestation and demonstration application of'Lucheng No.1'in saline-alkali land.
