Method for improving plant planting desert

Abstract

The invention relates to a method for improving a plant planting desert, which is realized by the following steps: adding 140 to 170kg of liquid film, 0.6 to 8kg of calcium magnesium phosphate, 0.01 to 0.2kg of ammonium molybdate and 0.4 to 5kg of nitragin of this family into 800 to 1300kg of water, stirring, dissolving, then adding 4 to 50kg of leguminous forage seed, stirring evenly, sowing on the sand of one hectare and enclosing and banning grazing for 3 to 5 years; and sowing 7 to 30kg of gramineous forage grass seed on the sand after the primary period, relieving enclosure and grazing banning after enclosing and banning grazing for 2 to 3 years and keeping the pasturage strength at 5 to 10 animals / year to achieve the ecological equilibrium of animals and plants so as to finish the improvement of the desert. By using the method, the usability of soil can be increased, the soil obtains sufficient water and nutrients, a woodland with large area can become a source of forest, the condition that the growth rate of the forest is greater than the exploitation rate is kept, the forest provides more oxygen gas used by organisms and assists to lower a warming phenomenon, buildings can be constructed again in part of regions with desertification reversion by the windproof protection of the forest, and the volume and the utilization rate of the soil are increased.

Description

technical field

[0001] The invention belongs to a method for desert improvement, in particular to a method for planting desert improvement. Background technique

[0002] China is one of the countries in the world where desertification and sandification have a large area, wide distribution, and serious hazards. Serious land desertification and sandification threaten my country's ecological security and sustainable economic and social development, as well as the survival and development of the Chinese nation. The status quo of desertified land: In 2004, the total area of ​​desertified land in the country was 2.6362 million square kilometers, accounting for 27.46% of the total land area, distributed in Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, Liaoning, Jilin, Shandong, Henan, Hainan, Sichuan, 498 counties (banners, cities) in 18 provinces (autonomous regions, municipalities directly under the central government) of Yunnan, Tibet, Shaanxi, Gansu, Qinghai, Ningxia, and Xi...
