Growth adaptability analysis of different mulberry varieties in coastal muddy saline-alkali soil
The growth adaptability indexes of different varieties of mulberry were studied in coastal saline-alkali land,which provided reference for the development and utilization of economic resources in coastal saline-alkali land of Zhejiang Province.The survival rate,fruit agronomic traits of 12 varieties planted on the muddy saline-alkali soil,as well as the soil physical and chemical properties in Wenzhou were compared and analyzed to determine the relative salt tolerance of each variety.The survival rate of different mulberry varieties varied greatly,the survival rate of Hebei Hong,Guoxuan 3 and 72C002 was the highest,more than 80%,while the survival rate of Qiong46 and Jinqiang 63 was lower,less than 30%.The growth performance of Hebei Hong,Qiangsang 3 and Guoxuan 3 were consistent with soil desalting ability,that is,the species with higher survival rate had less salt damage.Through the evaluation of agronomic indexes and salt-tolerance adaptability indexes of different mulberry varieties in coastal saline-alkali land,the suitable varieties of mulberry varieties are Hebei Hong,Qiangsang 3 and Guoxuan 3.
