Problems solved by technology

In view of the low number of arbuscular mycorrhizal fungal spores in the soil of the extremely arid desert area in the lower reaches of the Tarim River, and the low probability of arbuscular mycorrhizal fungal infection and colonization in the root system of Populus euphratica, a method was developed to increase the rate of transplanting young plants of Populus euphratica in the extremely arid desert area. Survival method
[0004] The patent No. 201110026829 is a method of inoculating arbuscular mycorrhizal fungi to increase the survival rate of artificial seedlings of Populus euphratica. It is aimed at the survival rate of seedlings and seeds with a plant height of 15-30 cm. The method does not determine the inoculation agent Dosage and soil sterilization methods are not convenient for large-scale production operations, and this method uses Hoaglund nutrient solution during seedling cultivation, while Hoaglund nutrient solution is generally not applied during plantation

Abstract

The invention discloses a method for increasing survival rate in transplanting populus euphratica shoots in an extremely arid desert area. The method includes the steps of populus euphratica shoot preparation, plant pit preparation, bacterium agent selection, transplanting vaccination and plant pit coverage. Formation of arbuscular bacteriorhiza in populus euphratica shoot roots is mainly promoted by means of one-time replenishing a moses ballon mold agent during transplanting of the populus euphratica shoots, so that the survival rate in transplanting the populus euphratica shoots can be increased, and drought resistance of the populus euphratica shoots can be improved. A novel method is provided for conservation and recovery of natural populus euphratical forests in the arid areas and manually structuring populus euphratical forests in the extremely arid desert areas.

Description

technical field [0001] The invention belongs to the technical field of restoration and reconstruction of degraded vegetation in arid areas, and in particular relates to a method for improving the survival rate of young Populus euphratica plants transplanted in extreme arid desert areas. Background technique [0002] Populus euphratica, also known as Populus euphratica or Populus heterophyllum, is a tall deciduous tree of the genus Populus in the Salicaceae family. It is the oldest and most primitive species of desert riparian forest in the genus Populus. It is one of the first batch of 388 rare and endangered plants identified in my country. . China is the country with the largest distribution range and the largest number of Populus euphratica in the world. 89.1% of the Populus euphratica forest area is concentrated in the Tarim Basin in Xinjiang. It plays a very important role in maintaining and regulating the fragile ecosystem balance in arid desert areas. However, due to ...
