Preparation method of multi-function volcanic-ash water absorbing and storing nutrient bag for desert

Abstract

The invention discloses a preparation method of a multi-function volcanic-ash water absorbing and storing nutrient bag for desert. The main point of the technical scheme is that the multi-function volcanic-ash water absorbing and storing nutrient bag for desert is a cylindrical cloth bag made of geotextile, the upper part of the cylindrical cloth bag is open and is used for adding a multi-functionvolcanic-ash water absorbing and storing nutrient conditioner for desert, and the bottom of cylindrical cloth bag is a closed round bottom. After the water absorbing and storing nutrient conditionerin the multi-function volcanic-ash water absorbing and storing nutrient bag for desert absorbs water and is expanded, sealing packaging is carried out for obtaining the finished product of the multi-function volcanic-ash water absorbing and storing nutrient bag for desert. The multi-function volcanic-ash water absorbing and storing nutrient bag for desert is suitable for various greening plants ina desert, and can timely provide water and nutrition required in the plant growth process, so that the survival rate of the planted various greening plants is improved, normal growth and developmentin the desert is ensured, the large-area afforestation rate in the desert is accelerated, the ecological environment of desertification land is improved, and the spread of desertification is prevented.

Description

Technical field [0001] The invention relates to a desert water storage and absorption bag, in particular to a preparation method of a multifunctional volcanic ash desert water storage and absorption nutrition bag. Background technique [0002] The final result of land desertification is mostly desertification. The types and distribution of desertification in China are: 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 mankind. China is one of the countries with the largest area of ​​desertified land and the most affected people in the world. [0003] Controlling land desertification is not only a major ecological and environmental issue, but also a very serious problem of sustainable social and economic development facing our country. Controlling...

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
