Method for improving survival rate of afforestation of non-woven fabric container seedlings in arid mountains

Abstract

The invention discloses a seedling growing matrix capable of improving the survival rate of afforestation of non-woven fabric container seedlings. The seedling growing matrix is composed of a matrix host material and a water-retaining agent. The matrix host material is composed of the following constituents, by weight, 40-50 parts of turf, 50-60 parts of fermentation carrier matrices and 10-20 parts of vermiculite. The addition quantity of the water-retaining agent is 3-4%. that of the matrix host material. The seedling growing matrix is suitable for cultivating container seedlings and applicable to improving the survival rate of afforestation of the non-woven fabric container seedlings in arid and barren mountains, and furthermore, the matrix and plant growth promoting rhizobacteria are used in a combined mode, so that the survival rate of afforestation is higher. The invention further discloses a method for improving the survival rate of afforestation of the non-woven fabric container seedlings. The method includes the steps that the seedling growing matrix is used for cultivating the non-woven fabric container seedlings first, before the non-woven fabric container seedlings are transplanted and fixedly planted, the plant growth promoting rhizobacteria are inoculated, and then transplanting and fixed planting are carried out.

Description

technical field [0001] The invention relates to a seedling raising substrate and a method for improving the survival rate of afforestation of non-woven fabric container seedlings in arid mountainous areas. Background technique [0002] According to statistics, the area of ​​arid and semi-arid regions in the world accounts for about 35% of the land area. The arid and semi-arid regions in my country have a vast territory, involving 12 provinces, municipalities and autonomous regions in the northeast, northwest and north China, accounting for about 52.5% of the total area of ​​the country. %. The resulting land desertification has made my country one of the most serious desertification hazards in the world. The arid and barren mountainous areas are the most severely affected by drought. The survival rate of afforestation in these areas is low, and soil erosion is serious. Therefore, increasing the survival rate of afforestation is a key factor for improving the ecological envi...

Problems solved by technology

However, drought will reduce the number of rhizosphere growth-promoting bacteria in the rhizosphere soil of plants, thereby changing the biological activity of the rhizosphere soil, which is not conducive to the absorption of nutrients and water by plants, thereby reducing the ability of plants to adapt to drought stress

At present, there is a lack of effective methods to improve the drought resistance of seedlings and the survival rate of afforestation in the afforestation of non-woven container seedlings.
