Desert greening soil module, and preparation and construction method thereof

Abstract

The invention relates to a desert greening soil module, and a preparation and construction method thereof. The soil module preparation method comprises the following steps: step 1, respectively preparing components according to weight ratios, wherein the components comprise 70-80% of soil (soil for use), 7-15% of an organic fertilizer, 0.5-2% of a soil micro-state active agent, 0.2-1.5% of a soilwater-retaining agent and 9-18.5% of water; step 2, uniformly stirring the components prepared in the step 1, adding water, then carrying out mixing to obtain mortar, carrying out mixing by stirring according to a soil water content ratio of 13-18.5%; step 3, putting the mortar into a mould, and pressing the mortar to form a soil module, wherein a column-shaped body is arranged in the mould, and avertically upward guide pipe hole is formed in the bottom of the soil module when the soil module is formed by pressing; and step 4, preparing a biodegradable conduit, and adding a rooting agent intothe conduit, wherein the rooting agent is a mixture of a soil water-retaining agent and rooting powder.

Description

technical field [0001] The invention relates to dry land greening technology, in particular to a desert greening soil module and its preparation and construction methods. Background technique: [0002] In our country, arid and semi-arid areas account for about half of the country's land area. Drought and water shortage have become the main obstacle to greening vegetation and improving the ecological environment. The dry and water-scarce climate of the desert seriously affects the growth and survival rate of vegetation. The application of anti-drought technology is mainly to transform the ecological environment of desertification and afforestation of barren hills. In recent years, drought-resistant afforestation technology has received widespread attention, and it is particularly important to improve the survival rate of afforestation, better control desertification, and afforestation on barren hills. Therefore, proposing the best vegetation drought resistance measures sho...

AI Technical Summary

Problems solved by technology

The influence of terrain features lies in the redistribution of precipitation by terrain, so this factor will have a significant impact on plant populations, and the general desert greening work is manual operations, including planting and irrigation, which increases the difficulty and cost

[0008] 2.2 Problems in desert planting

Although the concrete block of this building block can have high water permeability and high water retention performance, its shortcoming is: a layer of phenolic water retention cushion 2 is laid on the bottom of the large aggregate sandless concrete 3 to block the downward growth of plant roots, and also There is a defect that the root system is rolled into a group, and the plant root system cannot grow downward

Although the technology of guiding root system dryland tree planting of this patent application discloses the technology of guiding root system to grow downward, there are following problems in this technology: this method needs to drill deep holes, because the desert soil is loose and easy to collapse, it is not easy to successfully punch deep holes , It is not easy to put the bag into the deep hole in time, and it is not easy to succeed. The process of planting trees is complicated and difficult.

①The mountain protection function is low, which will induce landslides, tree falls, flood disasters, etc.

③Poor weather resistance and short life

However, wasting limited water resources, using a large amount of energy, and managing them for a long time is not an act of enriching the earth's environment, but a waste of precious resources.
