Problems solved by technology

However, the raw materials of the above-mentioned slope protection nets are plastics or non-woven fabrics, etc., which are not degradable under natural conditions. If they are left in the soil for a long time, they will pollute the soil, thereby affecting the penetration of plant roots to the surroundings; It is fixed on the slope, and then covered with soil around and above the slope protection net, which will increase manpower and material resources, resulting in an increase in cost

Embodiment 1

[0033] The rice stalk fiber bundles and water hyacinth obtained after silk rubbing and separation are separated by a fiber separator, and then refined by a high-consistency refiner to form a physical mechanical pulp, then added to a yellow cardboard, and pulped through a beating tank , add water-retaining agent, fertilizer-retaining agent and turfgrass seeds, stir and mix to form a slurry with a mass concentration of 0.8%, and mold it through pulp molding equipment to directly produce the semi-finished product of the bottom plate of the turf board. After air-drying or 10~ Drying at a low temperature of 25°C can produce a finished bottom plate. Wherein 35 parts by weight of rice stalks, 40 parts by weight of water hyacinth, 8 parts by weight of yellow cardboard, 5 parts by weight of lawn grass seeds, 6 parts by weight of water-retaining agent, and 6 parts by weight of fertilizer-retaining agent.

[0034] Figure 1~2 The bottom plate 5 of the soilless lawn is given, which is a ...

Embodiment 2

[0040] Mix soybean stalk fiber bundles and reed stalk fiber bundles obtained after silk rubbing and separation, and then use a high-consistency refiner to refine pulp to form physical mechanical pulp, then add yellow cardboard and pass through the beating tank Pulping forms a slurry with a mass percentage of 1.0%. Add a water-retaining agent to the slurry, stir and mix it, and mold it through a pulp molding equipment to directly produce a semi-finished lawn bottom plate. After air-drying or 10 ~25℃ low temperature drying can make the finished bottom plate. Among them, 40 parts by weight of soybean stalk fiber bundles, 40 parts by weight of reed stalk fiber bundles, 5 parts by weight of yellow cardboard, and 6 parts by weight of water-retaining agent.

[0041] In the same way, the wheat stalk fiber bundles and dried cow dung obtained after silk rubbing and separation are separated and pulped, added with yellow cardboard for beating, added with water retaining agent, mixed evenl...

Embodiment 3

[0044] Cut the dry reed stalks into small pieces of about 5cm, soak them in lime water for 45 minutes, rinse them twice with clean water, add dry cow dung, mix them, and then process them with a wire separator, and use a high-consistency refiner to refine After the physical mechanical pulp is formed, the yellow cardboard is added, and the pulp is made through the beating tank. Add water-retaining agent, fertilizer and ryegrass seeds to the slurry, stir and mix to form a slurry with a mass concentration of 2.5%, and mold it through pulp molding equipment to directly produce the semi-finished product of the bottom plate of the lawn board. After air drying or low temperature drying at 10~25℃, the finished bottom plate can be obtained. Wherein, 30 parts by weight of reed stalks, 30 parts by weight of dry cow dung, 5 parts by weight of yellow cardboard, 5 parts by weight of water-retaining agent, 8 parts by weight of ryegrass seeds, and 2 parts by weight of fertilizer-preserving ag...

Abstract

The invention discloses soilless lawn and a preparation method of the soilless lawn. The soilless lawn comprises a bottom plate and an upper cover, wherein the bottom plate is mainly prepared by using fiber biomass or mixing the fiber biomass with low-grade biomass, carrying out devillicating treatment by a devillicating machine, then carrying out pulp grinding for forming physical mechanical pulp, adding paper boards for pulp making, adding water-retaining agents and / or fertilizer retaining agents and / or grass seeds, uniformly mixing materials via stirring, carrying out molding forming, and drying the materials; and the upper cover is mainly prepared by using low-grade biomass or mixing the low-grade biomass with the fiber biomass, carrying out devillicating treatment by the devillicating machine, carrying out pulp grinding for forming physical mechanical pulp, adding paper boards for pulp making, adding the water-retaining agents, uniformly mixing materials via stirring, carrying out molding forming, and drying the materials. The biomass materials are adopted, the goal of fixing the lawn can be reached, in addition, the normal growth of the lawn cannot be influenced, because the biomass materials can be degraded by microbes, the nutrition is provided for the growth of the lawn, and in addition, the soil pollution caused by the use of plastic or nonwoven lawn plates is avoided.

Description

technical field [0001] The invention belongs to the fields of agricultural environmental engineering and biotechnology, and relates to a soilless lawn and a preparation method thereof. Background technique [0002] In order to prevent soil erosion on slopes, people mostly plant lawns on various slopes and slope protection zones. However, due to the impact of rainwater and the inclination of the slope, other substances are needed when the flat lawn is fixed on the slope. The slope protection technology of vegetation is developing very fast at present, and for example, the patent No. 99251700.1 and the patent No. 200520079346.1 are "vegetation slope protection net" and the patent No. 00221956.5 is "vegetation slope protection net with cushion net". However, the raw materials of the above-mentioned slope protection nets are plastics or non-woven fabrics, etc., which are not degradable under natural conditions. If they are left in the soil for a long time, they will pollute the...
