Rapid greening method for desert land with mechanized operation

Abstract

The invention discloses a rapid greening method for desert land with no tillage, no irrigation, no fertilizer, no care, and fully mechanized operation. The method includes the following steps that domestic garbage and solid waste from agriculture, forestry and animal husbandry are processed into high-quality guest soil for water retention and fertilizer conservation; the high-quality guest soil ismade into a block or granular material which is easy to transport and lay; plant seeds are evenly stirred in the guest soil; a special paver is used for laying the guest soil on the desert land wheregrass does not grow; the guest soil is compacted by a roller carried by the paver; the compacted guest soil can prevent wind, fix sand, absorb water and promote rooting, germination and greening of plants to achieve regeneration of desert vegetation. No care is needed during the period.

Description

technical field [0001] The present invention relates to a treatment technology of no-tillage, no-irrigation, and no-nursing of desertified land (desert, rocky desert, and saline desertification); more specifically, the present invention relates to a method of using domestic garbage and adopting fully mechanized operation A method for rapidly greening desert land. Background technique [0002] With the development of the economy, the deterioration of the ecological environment has become more and more serious, and it has reached the point of non-heavy governance. According to the statistics of the United Nations Environment Program (UNEP), the areas that have been and are expected to be affected by desertification in the world account for 35% of the global land area. Deserts and desertified land occupy 55% of Africa, 19% of North and Central America, 10% of South America, 34% of Asia, 75% of Australia and 2% of Europe. Deserts and desertified lands cover 95 percent of the l...

Problems solved by technology

This technology can play a role in preventing quicksand from moving in the short term (2-3 years), but it has obvious shortcomings: 1. The cost is high

Building an acre of grass grid requires a material cost of 800 yuan, while the material cost of artificial vegetation technology (AVT) is only about 400 yuan; 2. Low efficiency

The grass grid technology is all manual operation, which is labor-intensive and low-efficiency. One laborer can only plant 0.2-0.3 mu a day, while the artificial vegetation technology is all mechanized operation, which greatly reduces labor intensity, and the work efficiency is dozens of times that of manual operation.

3. The function of the grass grid technology is single, it only plays the role of preventing the drift of quicksand, and it cannot green the desert. To green the desert, other planting technologies are required.

Liquid membrane technology does have a good effect in quickly fixing moving sand, but it also has quite a few defects: 1. The effect is single, it can only fix sand, cannot plant plants, and cannot afforestation; As a permanent cure, the life of the liquid membrane is only two years. After two years, the liquid membrane will be completely degraded and the mobile sand dunes will be exposed again; 3. The cost is high and it cannot be applied to desert control on a large scale; 4. Since the liquid membrane uses chemical products as the basic raw materials , after its degradation, it will still produce secondary pollution, which is not conducive to environmental protection

This technology seems to be very novel in theory, but there are still many problems before the real large-scale promotion and use: 1. The cost is too high

This method collects and pulverizes various waste organic matter (including domestic garbage), adds adhesive, water, nutrients, plant seeds, etc., stirs, and then lays, and the matrix nutrient layer is mainly organic matter; its disadvantage is that this method is not applicable Unlike ordinary domestic waste containing a large amount of inorganic matter, the place for stacking and retting should not be far away from the place where it is paved, and it is not suitable for long-distance transportation. There are certain conditions
