Method for increasing calligonum drought stress resistance recovered by manpower on arid desert

Abstract

The invention relates to a method for improving drought stress resistance of artificially restored Calligonum rubicundunm in a drought desert area, which comprises the following steps of nursery stock selection, early soil preparation, early nursery stock treatment, irrigation treatment and the like, and utilizes a feedback regulation system formed through drought induction of partial root systems of the Calligonum rubicundunm to improve the adaptive capacity of the Calligonum rubicundunm to the drought so as to achieve the aim of improving the integral drought stress resistance of the artificially restored Calligonum rubicundunm in the drought desert area and avoid converse succession after the artificial assistance measures are cancelled. The method realizes survival and growing development of artificially restored Calligonum rubicundunm seedlings by means of the drought stress resistance of the Calligonum rubicundunm seedlings under the natural conditions of precipitation amount less than 100 mm and drought climate after the artificial assistance measures are cancelled.

Description

Method for Improving the Drought Stress Resilience of Artificially Restoring Azalea Jujube in Arid Desert Area technical field The invention relates to a technique for improving the drought stress resistance of vegetation restoration in arid desert areas, and in particular to a method for artificially restoring the drought stress resistance of Jujube japonica in the arid desert area. Background technique The total area of ​​arid and semi-arid regions in my country accounts for about half of the total area of ​​the country. The national desert and desertification land area reaches 1.533 million square kilometers, accounting for 15.9% of the country's land area. It is one of the countries with the largest desert area, wide distribution and the most serious desertification hazards in the world. Xinjiang is located in the hinterland of the Eurasian continent and has a typical continental arid climate. Most areas are in semi-arid, arid and extremely arid areas. The soil develo...

AI Technical Summary

Problems solved by technology

The traditional flood irrigation along the surface or single irrigation along the planting ditch for artificially restored vegetation often has the disadvantages of low water resource utilization efficiency and serious evapotranspiration waste, and the artificially restored Jujube seedlings in the arid desert area have no artificial irrigation assistance and lack of natural resources. Under the condition of precipitation, it is often difficult to survive in the later stage due to insufficient resistance to drought

Degradation and reverse succession of restored vegetation often occur, reducing ecological restoration performance
