Embodiment 1

[0016] 1. Soil testing: In March, soil was taken from desertified soil with a vegetation coverage rate of 15% for testing (the test instrument was a TFC-1B soil fertilizer tester), and soil available nitrogen, available phosphorus, available potassium, total nitrogen, and total nitrogen were measured. Phosphorus, total potassium, and organic matter content are lower than the soil standards of "Green Planting Soil";

[0017] 2. Select vegetation: select seeds of desert-resistant plants, Achnatherum splendens seeds that have a growth advantage in the local area, and the purity of the seeds is 96%;

[0018] 3. Soil preparation: shallow plowing and light raking of the soil, the depth of shallow plowing is 11cm;

[0019] 4. Fertilization: The following components are counted in parts by weight: fertilizer includes 62kg of peat, 12kg of ammonium carbonate, 8kg of phosphorus pentoxide, 12kg of potassium oxide, 2kg of zinc fertilizer, 2kg of sulfur fertilizer, 2kg of nitrogen-fixing b...

Abstract

The invention discloses a desertification soil management method, which relates to a soil source improvement method and belongs to the field of the environmental management. According to the desertification soil management method, the problems of small possibility of popularizing the desertification soil management method on a large scale as well as the defects of aggravated soil desertification, and big investment, high cost and slow effect on treating desertification soil are solved. The desertification soil management method comprises the following steps of testing soil, selecting vegetation, preparing soil, fertilizing and sowing. In the fertilizing step, fertilizer comprises the following components in parts by weight: 45-60% of turf, 11-20% of ammonium carbonate, 5-10% of phosphorus pentoxide, 9-18% of potassium oxide and 1-3% of nitrogen-fixing bacteria, wherein the fertilizer and the soil are mixed in parts by weight of 1:4-2:7, and the application amount of the turf on each acre is 30-50kg. According to the desertification soil management method, the desertification soil is fundamentally managed, the soil physicochemical property is changed, the soil fertility is improved, and the soil desertification situation is thoroughly changed.

Description

technical field [0001] The invention relates to a method for improving soil sources, which belongs to the field of environmental management, in particular to a method for controlling desertified soil. Background technique [0002] The Hexi Corridor on the Northwest Plateau of China is the throat of the world-renowned ancient Silk Road, and it is also an extremely thirsty corridor. The Shiyang River Basin is located at the eastern end of the Hexi Corridor, and there is a vast oasis in its downstream called Minqin Oasis. Due to the large increase in population, people reclaim wasteland with unreasonable resources in Minqin, especially in the areas where the protection forest system is not perfect and the irrigation measures are not perfect. Large-scale and disorderly land reclamation has resulted in the destruction of the transition zone protection system between the oasis and the desert. Without the anti-sand barrier, the expansion of deserts to oases accelerated. The incr...
