Abstract

The invention provides a freeze thawing resistant afforestation planting base material suitable for extra-high altitude regions and a use method of the freeze thawing resistant afforestation plantingbase material suitable for extra-high altitude regions. The freeze thawing resistant afforestation planting base material suitable for extra-high altitude regions comprises a three-layer structure, wherein an upper layer is a freeze thawing resistant permeable layer, a middle layer is an isolating layer, a lower layer is a water retention layer, the freeze thawing resistant permeable layer comprises clay, coarse-crushed highland barley straw, casein, water repellents and water, the water retention layer comprises clay, fine-crushed highland barley straw, yak excrement and urine, casein, waterretaining agents and water, and the isolating layer is a degradable plastic film. The planting substrate provided by the invention has the beneficial effects of being higher in intensity and freeze thawing resistant properties, and capable of reducing water and soil erosion phenomena caused by frequent rain washing, and besides, capable of providing ample moisture for plant growth.

Description

technical field [0001] The invention relates to the technical field of planting substrates, in particular to planting substrates suitable for ultra-high altitude areas. Background technique [0002] my country's ultra-high-altitude areas have the characteristics of high and cold winters. The greening substrate's repeated freezing and thawing will reduce its strength, so it cannot resist the frequent rain erosion in the rainy season, resulting in soil erosion and reducing the greening effect. Therefore, the freeze-thaw resistance of the greening substrate can be improved. It will be conducive to the development of greening work in ultra-high altitude areas, reduce the cost of greening maintenance, and improve the effect of greening. The climatic characteristics of ultra-high altitude areas cause surface evaporation to be greater than precipitation. The growth of vegetation in greening work requires a lot of water, and the commonly used method to increase the freeze-thaw resist...
