Embodiment 1

[0047] A plan for a certain place in Inner Mongolia Autonomous Region

[0048] 1. Formulate a detailed overall plan for the governance area.

[0049] 2. Do a good job of land leveling in the governance area according to the plan.

[0050] 3. The trench grid plane layout is based on the middle-middle square grid size of 4.5m×4.5m, the trench width is 50cm, and the depth is 70cm. Simultaneously do the burying of the main pipe and branch pipes of the irrigation pipe network, and fill the bottom of the trench with Type I improvement ground, with a thickness of 40cm, and finally backfill the trench to make it level.

[0051] The formula of type I improver is as follows:

[0052] 3.1 Dry cow dung (powder) 35%.

[0053] 3.2 Biomass straw powder 35%.

[0054] 3.3 Weathered coal powder (containing more than 50% humic acid and more than 70% organic plants) 25%.

[0055] 3.4 Agricultural medical stone powder 5%.

[0056] 3.5 After the above four materials are mixed evenly, add an a...

Embodiment 2

[0061] A plan for a certain place in Inner Mongolia Autonomous Region

[0062] 1. Formulate a detailed overall plan for the governance area.

[0063] 2. Do a good job of land leveling in the governance area according to the plan.

[0064] 3. The trench grid plane layout is based on the middle-middle square grid size of 5.0m×5.0m, the trench width is 40cm, and the depth is 60cm. Simultaneously do the burying of the main pipe and branch pipes of the irrigation pipe network, and fill the bottom of the trench with Type I improvement ground, with a thickness of 30cm, and finally backfill the trench to make it level.

[0065] The formula of type I improver is as follows:

[0066] 3.1 Bio-organic fertilizer 75%

[0067] 3.2 Lignite powder (containing humic acid ≥ 50%, organic matter ≥ 70%) 25%.

[0068] 3.3 After the above two materials are mixed, an appropriate amount of agricultural compound probiotics is added, and the effective number of viable bacteria reaches ≥0.2 billion / g...

Abstract

The invention belongs to the technical fields of desertification control and desertification agricultural development and creates technical principle and method for desertification control. Accordingto the method, on the premise of making regional planning and land leveling, measures of applying an I type improver with adsorbing, water-retaining, fertilizer-retaining and impermeable functions toa groove which is excavated according to a square grid, backfilling the groove to be flat as well as applying an II type improver to the surface layer of the desert, performing rotary tillage and thenleveling are taken well; the formulas of the improvers are prepared through scientific combination of various industrial and agriculture organic waste, an excellent organic carbon fertilizer and an agricultural composite microbial agent according to the circular economy development concept and the principle of reducing treatment cost as much as possible; moreover, the wind-proof and sand-fixing measures are taken well by building greenhouses in a staggered way and planting green barriers; and a water source and efficient water-saving irrigation scheme is formulated by combining the specific condition of water resources, high-quality agricultural scientific and technical resources at home and abroad are integrally utilized, and the economic and social benefits of changing the desert into the fertile land are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of desert control and desertification agriculture development, and specifically relates to a set of innovative technologies for ecological sand control to turn deserts into fertile oases. Wrong concept, fundamentally reverse the situation of backward desert control technology. Background technique [0002] The spread of global desertification has caused an imbalance in the ecosystem, and the area of ​​arable land has been shrinking... my country is one of the countries with the most severe desertification in the world. The desert and desertified land in the arid northwest region have become one of the main sources of sandstorms, which have a negative impact on China's industrial and agricultural production. It has seriously affected people's lives and caused huge losses to the country and the social economy. For a long time, desert control has made great achievements and accumulated rich experience, but it i...
