Description

Biological rain collection material assembly block and production method

technical field

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

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 limited rainfall resources and improve the utilization rate of rainwater resources to improve the water shortage in arid and semi-arid areas. The patent applicant once disclosed the invention patent with the patent No. 03143265.4 "A Method for Rapid Artificial Propagation of Lichens". Lichens and mosses can live in various environments, and are especially resistant to drought and cold. They are pioneers in the pioneering of the plant world. Utilizing its biological characteristics as a rainwater collection material to collect surface runoff, the rainwater collection surface for crop supplementary irrigation plays an important role in rainwater utilization. However, since the construction process of biological rain-harvesting surfaces is the process of breeding and cultivating biological rain-harvesting materials, it requires high-intensity manual management measures, labor-intensive, and cumbersome operations, so it is difficult to popularize and apply them in vast mountainous areas and deserts.

2. The culture medium used is cotton gauze with a mesh of 1×1mm ^2. Before use, the gauze is completely immersed in water, and after drying, it is cut into gauze pieces of 50×50cm ² and mixed with 1% carboxymethyl cellulose material. (CMC) or starch; the substitute for the above-mentioned cotton gauze can also choose chemical fiber non-woven fabric or paper with better strength, mainly as the support of biological materials, and requires water and air permeability, as the culture medium is transparent up and down.

3. Spread the vegetable garden soil that has passed through a 50-mesh sieve in a plastic tray of 50×100×15cm ³ . The soil thickness is 5cm. After the soil surface is leveled, spread the gauze taken from the CMC on the soil surface (or directly Spread in the field), remove the air bubbles between the gauze and the soil surface, water it thoroughly with a watering can, and evenly spread on the gauze mixed with urea 0.08g, KH ₂ PO ₃ 0.38g, MgSO ₄ .7H ₂ O 0.13g and NaCl 0.13g of 100g lichens and moss sieved soil; in the above biological materials can also include water absorbing agents, such as: PMA (polyacrylamide), starch-acrylonitrile graft copolymer, starch-acrylic acid graft copolymer, acrylic acid wait.
