Drought Resistance and Heavy Metal Adsorption Capacity of Mulberry in Alpine Regions

Abstract

Mulberry is an important perennial economic crop. It is the pursuit of modern mulberry breeders to continuously improve the drought resistance and heavy metal adsorption capacity of mulberry varieties. In this paper, three excellent mulberry varieties were introduced and cultivated in the alpine region, and the drought resistance of mulberry seedlings under different drought degrees and different days of drought was analysed. The root powder of mulberry seedlings was ground and dissolved by combining physical and chemical methods. The heavy metal ions are taken as an example. The heavy metal adsorption capacity of the root powder of mulberry seedlings under different initial ion concentrations and different pH values is analysed. The experimental results show that the drought resistance of different varieties is different. The concentration of heavy metal ions and pH value can only be achieved.
