Description

Plant cultivation device for collecting water and preventing evaporation

The invention relates to the technical field of forest restoration in desertified areas, in particular to a plant cultivation device for collecting water and preventing evaporation, which is suitable for afforestation projects in desertified areas and provides more favorable growth conditions for afforestation seedlings.

There is already a huge amount of land on the earth today, and due to human factors such as deforestation, irrational farming and animal husbandry, or natural factors such as climate drought, it is gradually developing towards the process of desertification. The United Nations Convention to Combat Desertification clearly defines desertification as "land degradation in arid, semi-arid and semi-humid dry areas due to various factors (including climate change and human activities)". At present, drylands account for about 40-41% of the earth's land area, and about 10-20% of the drylands have been desertified. These land degradations lead to reduced productivity and more difficult access to natural resources and opportunities, especially in agriculture-based areas. In developing countries, it is enough to directly cause the residents to live in poverty. In order to combat land desertification in arid areas, forest land restoration is a fundamental control method. Planting appropriate trees on arid land adjacent to deserts not only resists desertification, but also has the functions of water and soil conservation and water conservation.

The seemingly easy-to-achieve plan of forest land restoration is often affected by various factors in actual implementation, which leads to the death of the planted tree seedlings, and ultimately falls short of success. Among them, the more important thing is that after the seedlings are transplanted to the dry land, certain protection and stable water supply must be applied to the seedlings for a period of time, so that they can resist drought and strong wind in the initial stage of transplantation. For this reason, one of known technology puts a section of PVC protective tube on the transplanted seedlings to make it grow in the protective tube to resist strong wind, but if this PVC protective tube is not reclaimed, it will form non-decomposable garbage. pollution, and recycling one by one will increase the cost of forest land restoration, so it is not a good technical solution.
