Manufacturing method for combined type volcaniclastic rock desert water storage and absorption device

Abstract

The invention discloses a manufacturing method for a combined type volcaniclastic rock desert water storage and absorption device. According to the technical scheme adopted by the invention, the key point is that the manufacturing method comprises the following steps of: connecting a tapered water storage tube on the bottom of a porous water storage and absorption cylinder tube; placing a multifunctional volcaniclastic rock desert water storage and absorption nutrient bag in the porous water storage and absorption cylinder tube, wherein a multifunctional volcaniclastic rock water storage and absorption nutrient conditioning agent is in the multifunctional volcaniclastic rock desert water storage and absorption nutrient bag; forming a plant growth slot in the upper part of the porous waterstorage and absorption cylinder tube through a flange disc; and adding volcaniclastic rock compressed nutrient soil in the plant growth slot, thereby forming the combined type volcaniclastic rock desert water storage and absorption device. The combined type volcaniclastic rock desert water storage and absorption device is suitable for planting various desert greening plants in the desert, can timely provide water and nutrients needed in a desert greening plant planting process to increase a survival rate of various planted desert greening plants, ensures normal growth in the desert, increaseslarge-area forest planting speed in the desert, and improves the ecological environment of desertification land.

Description

technical field [0001] The invention relates to a desert water storage and absorption device, in particular to a preparation method of a combined pyroclastic desert water storage and absorption device. Background technique [0002] The final result of land desertification is mostly desertification. The types and distribution of desertification in China include four types of desertified land: wind erosion desertification, water erosion desertification, freeze-thaw desertification, and soil salinization. Desertification is no longer a purely ecological and environmental problem, but has evolved into an economic and social problem, which brings poverty and social instability to human beings. China is one of the countries with the largest desertified land area and the most affected population in the world. [0003] Controlling land desertification is not only a major ecological and environmental problem, but also a very serious social and economic sustainable development proble...

Problems solved by technology

[0008] The disadvantages of the above-mentioned patents are: the invention is only a water storage and delivery device, which cannot store water in the desert into the water storage and delivery device, and cannot be used to transform arid areas such as barren lands and deserts, and cannot improve the quality of arid areas. Survival rate of planted plants

[0010] The disadvantage of the above-mentioned patent is: among the raw materials used in this invention, corn stalk pith, sawdust, red brick crumbs and attapulgite clay powder can absorb a small amount of water.

Corn straw pith contains a certain amount of fat, its moisture content is ≤30%, and the moisture content of sawdust is ≤40%. Corn straw pith and sawdust can absorb a small amount of water; The water absorption rate after boiling for 5 hours is ≤25%, and the red brick particles can only absorb a small amount of water; the attapulgite clay powder in this invention is a powdery product processed by high-quality attapulgite through beneficiation, drying, grinding and other processes , those skilled in the art know that attapulgite clay powder has not been modified, and when its water absorption rate is ≥ 40%, it appears as a paste-like substance, which is just a binder, which cannot continue to absorb water, and the water absorption effect is not good. it is good
