Embodiment Construction

[0018] The present invention will be further described below in conjunction with the production of lichen-moss mixed biological rain-collecting material assembly block as an application example.

[0019] 1. The lichens and mosses are taken from the slopes of the Taihang Mountains in Yuanshi, Hebei Province. They are soil crusts with lichens and mosses, about 2mm thick, crushed and passed through a 50-mesh sieve for use;

[0020] 2. The culture medium used is 1×1mm 2 Mesh cotton gauze, soak the gauze in water completely before use, cut it into 50×50cm after drying 2 Gauze block, and soaked in 1% carboxymethyl cellulose material (CMC) or starch; the substitute of the above-mentioned cotton gauze can also choose chemical fiber non-woven fabric or paper with better strength, mainly as biological material The support also requires water and air permeability, as the culture medium is transparent up and down.

[0021] 3. Spread the vegetable garden soil that has passed through a 50...

Abstract

The invention provides a method for producing the biological assembly material for the rain collecting and maintaining and provides a half-finished product of biological crust which can be lied instantly and is facilitating for transportation and easy for mass production, which creats favourable conditions for the large-area spread and use. The said material concludes: the culture medium employing a kind of fibrous material, the surface soil lied on the culture medium with the coverage of lichens or moss which is used as the rain-collecting biological material. The invention is used for the repairing and constructing of the rain-collecting slope in the arid or half-arid area, which can increase the slope runoff coefficient and collecting efficient, and possesses the characteristics of durability, environmental protection, soil and water conservation, improvement of the soil physicochemical deseription and promoting the soil development, etc. The rain-collecting material possesses a great potential for usage.

Description

technical field [0001] The invention relates to a production technology of a biological rain-collecting material assembly block, and belongs to the technical field of artificial propagation of lower plants and rainwater utilization. Background technique [0002] In arid and semi-arid areas, groundwater and surface water resources are seriously or seasonally scarce, and rainfall is the only large water source available. However, due to the very uneven distribution of rainfall in a year, it is seriously misaligned with the water demand period of crops, resulting in insufficient water becoming a bottleneck limiting plant growth. At the same time, the utilization rate of rainfall is low, the efficiency of water production is low, and the runoff generated in the rainy season is easy to cause serious soil erosion, leading to soil erosion and degradation, and the continuous deterioration of the ecological environment. Therefore, it is very important to artificially regulate the li...
