Application of edible fungus mycelia in water retention and sustained release of fertilizer of soil, desertified land and stony desertified land

Abstract

The invention discloses application of a biodegradable straw mycelia material prepared by adopting edible fungus mycelia to ferment straws. The straw edible fungus mycelia material is a growth matrixusing the straws rich in fibers as edible fungus mycelia, and the edible fungus mycelia is used for binding and forming the straws. The novel degradable material can be used as a moisturizing materialand a salt-resistant material of the soil, the destertified land and the stony desertified land, can also be used for fixing inorganic fertilizer and organic fertilizer, and is made into a sustained-release fertilizer material for cultivating plants. The raw materials are simple and easy to obtain, the production cost is low, a great amount of agricultural waste can be treated, the prepared material can be widely applied in the agriculture and forestry, the whole production process is green, no secondary pollution is produced, after the material is applied to the soil, the water retaining performance of the soil is improved, as biomass is slowly degraded, the fixed fertilizer is released to fertilizer the soil, an effect for resisting the drought, retaining the water and promoting the plant growth as well as resisting the salt and alkali for a long time can be achieved, the biodegradable straw mycelia material can substitute the commercially-available chemically-synthesized water-retaining and sustained-release fertilizer, so that the pollution for the soil can be further reduced.

Description

technical field [0001] The present invention relates to a kind of straw resource utilization and a large amount of water-absorbing and water-retaining fiber material, in particular, relates to the application of a kind of straw edible fungus mycelium material in water retention and fertilizer slow-release in soil, desertification land and stony desertification land, It belongs to the application of new degradable materials in soil water retention, desertification and stony desertification control. Background technique [0002] The total area of ​​arid and semi-arid regions in my country is 4.55 million km 2 , accounting for 47% of the country's land area, the lack of water resources has become an important factor restricting the sustainable development of my country's agriculture and forestry. In the sandy land of arid and semi-arid regions, the low survival rate of afforestation is an urgent problem to be solved. There are many factors affecting the survival and growth of...
