Problems solved by technology

[0005] However, for arid areas where guest soil spraying technology is used for greening, since water cannot be fixed in the spraying layer, the construction covering layer will gradually wither and peel off with the disappearance of nutrients and water.
The greening effect is not ideal, the duration is not long, and it also increases the cost of greening

Embodiment 1

[0023] A kind of greening spraying method that is used for arid area of ​​the present invention, it comprises the following steps:

[0024] 1) First prepare a soil composition, the soil composition weight components include 10-20% sandy soil, 50-75% animal and plant fertilizers, 2-10% acidic soil flora, 5%-organic decomposition flora 25% and 7%-25% of nitrogen-fixing bacteria. After in-depth ratio research and soil effect test, it is found that when the components in the soil composition are mixed according to the above ratio, its effect on soil improvement is the best;

[0025] 2) Then add the fermented straw bark to the soil composition first, then add vermiculite and perlite to form a soil composition with aggregate structure for water retention, and the straw bark should be crushed into a length of 5-10 mm before fermentation It is in the form of fibers, which are added to the soil composition to form a supporting skeleton of the aggregate structure. The diameter of vermic...

Embodiment 2

[0055] The present embodiment is basically the same as Example 1, except that the weight component of the soil composition is preferably sandy soil 10%, animal and plant fertilizer 50%, acidic soil flora 5%, organism decomposing flora 15% and Nitrogen-fixing bacteria 20%.

Embodiment 3

[0057] The present embodiment is basically the same as Example 1, except that the weight component of the soil composition is preferably sandy soil 12%, animal and plant fertilizer 60%, acidic soil flora 10%, organism decomposing flora 8% and Nitrogen-fixing bacteria 10%.

Abstract

The invention discloses a greening hydro-seeding method used for arid areas.. Firstly preparing a novel soil composite; then adding straw bark into the soil composite, then adding vermiculite and perlite; mixing, adding water to and stirring the soil composite formed into aggregate structures, bonding agents and seeds, spraying the mixture on areas to be greened through a wet spraying machine; after spraying, firstly spraying water-retention agents and then covering thin films on a hydro-seeding layer formed on the areas; at last, arranging a plurality of drip irrigation tubes in the areas and digging water storage pools communicated with the drip irrigation tubes in the areas. The greening hydro-seeding method can improve germination rate and survive rate during early hydro-seeding stages, and moisture required by plant growth can be maintained through a plurality of water retention and water supply methods. The greening hydro-seeding method used for arid areas is simple in construction method, low in construction cost and suitable for being popularized in large scale in arid-area side slope greening hydro-seeding.

Description

technical field [0001] The invention relates to a greening spraying method, in particular to a greening spraying method used in arid areas. Background technique [0002] With the rapid economic and social development and the acceleration of urbanization, the construction of infrastructure in China has also accelerated, and a large number of exposed slopes have been formed due to the implementation of construction projects such as transportation, water conservancy, mining, and electric power. These exposed slopes not only affect the ecological environment and landscape, destroying the natural ecological balance of the area, but also some slopes have serious hidden dangers of geological disasters, affecting the safety and stability of the main project, and even endangering people's lives and property safety. Therefore, slope greening has very important environmental protection and practical significance. Slope greening can not only beautify the environment, conserve water sour...
