Description

An expandable desert greening brick and greening culture tank

technical field

The invention relates to the technical field of ecological environment protection and transformation, in particular to an expandable desert greening brick and a greening cultivation tank.

Background technique

The land area affected by desertification on the earth is more than 38 million square kilometers. At present, about 6 million hectares of land in the world experience desertification every year. The increase in sandstorms since the 1990s is directly related to the deterioration of ecology and the spread of desertification in northern my country. The average annual expansion rate of desertified land in northern my country has been expanding at a rate of 2,460 square kilometers per year since the 1990s. Desertification has caused serious losses to agriculture, animal husbandry and people's living property in many countries and regions. China is one of the countries most seriously harmed by desertification in the world. The area of desertified land has reached more than 3,000 square kilometers every year, and the annual direct economic loss due to desertification exceeds 54 billion yuan. Therefore, finding an effective method of desert control and reducing the economic loss caused by desertification has become a national and even a worldwide issue. At present, the desertification control methods used in the world mainly include planting trees and grasses, returning farmland to forests, chemical sand fixation, etc. Although these methods have certain effects, there are deficiencies in varying degrees:

(1) Planting trees and grass, returning farmland to forests and other methods: In the past few decades, the state has invested a lot of manpower and material resources in the prevention and control of desertification. The Beijing-Tianjin sandstorm source control project, etc., because the annual rainfall in 90% of my country's desertified areas is below 400 mm, except for local areas with better water conditions, they cannot meet the conditions required for "afforestation". Recent studies have shown that, Only about 10% of the desertified land has been treated, and 12% of the desertified land has been restored to varying degrees. The state of "partial reversal, overall deterioration" has not been fundamentally changed, and the situation of land desertification is still severe.

(2) Chemical sand fixation: mainly cement slurry, water glass, petroleum products and polymers, etc., but the disadvantages of using these methods are low and thin solidified layer, incomplete curing, and easy to cause secondary pollution , Poor anti-aging performance, etc.
