Description

A plant-growing yarn for planting lawns and its production process and its woven products

technical field

The invention relates to a vegetable yarn used for planting lawns, and also relates to a production process of the vegetable yarn and a woven product using the vegetable yarn.

Background technique

China has a vast territory, with great differences in climate and soil, and the natural environment of each region also has great differences. With the development of my country's economy and society, as well as the enhancement of people's awareness of environmental protection, the government has increased investment in sand prevention and sand production, water conservation and soil stabilization, river and ditch management, and urban greening. Planting turf is a common management or greening method, but the usual method of planting turf is to shovel out the turf in the grass garden with a shovel, transport it to the place to be planted, and then divide it into small pieces of turf and plant it. However, due to the thin turf, the grass roots are easily damaged during the planting process, and the water loss is large, which affects the survival rate of the seedlings after planting.

As an important part of the environmental ecosystem, the lawn can beautify the environment, purify the air, prevent soil erosion, etc. It is an indispensable part of modern urbanization. In order to meet the development needs of urbanization, it has become an important topic to study how to save urban space and how to increase the urban green area. Among them, the development and planting methods of soilless grass mats have been promoted to an important position. Lawn is an important part of urban afforestation, and it is the most widely used variety in afforestation in various countries in the world. Grass blanket is a kind of lawn grass that can be easily rolled up like a carpet, with a specification of more than 1 square meter, can be cut at will, light in weight, construction method, and convenient transportation. The production of ordinary turfgrass is generally to sow grass seeds or grass stems in the soil, grow into a lawn after a certain period of time, and then shovel the turf with roots and soil together. It is produced 1-2 times a year, and a layer of about 20mm of soil must be taken away each time we shovel. This kind of turf has a long growth cycle and low efficiency, which has a destructive effect on cultivated land and easily causes water and soil erosion. Or make it into the form of a grass blanket, but the bottom layer generally used in the prior art is made of plastic material. As we all know, the plastics we usually use have many hazards:

1. Seriously affect our health. When the temperature reaches 65°C, the harmful substances in the disposable foam plastic tableware will penetrate into the food, causing damage to the human liver, kidneys and central nervous system. If the discarded plastic products are sticky with pollutants, they will become a hotbed for the survival and reproduction of mosquitoes, flies and bacteria, endangering human health.

2. The main raw materials of plastic bags used in daily life are polyethylene and polyvinyl chloride. When people are exposed to vinyl chloride, symptoms such as edema of wrists and fingers, skin hardening, etc. may also occur, such as splenomegaly and liver damage.

3. If it is buried underground, it will take about 200 years to rot, which will have a negative impact on the pH of the soil and deteriorate the soil environment. After the plastic film used in the farmland ages, it will be broken and left in the field without decomposing and rotting. Destroy the land structure, hinder the water absorption and root growth of plants, and affect the harvest of crops. According to investigations, if each field contains 3.9 kilograms of residual film, the yield of corn can be reduced by 11-23%, and the yield of wheat can be reduced by 9-16%. Moreover, this kind of pollution is difficult to eliminate. Seriously affect the growth of crops. If the livestock eat the plastic film, it will cause digestive tract diseases of the livestock, and even death. If it is landfilled, it will directly occupy the land, and it will be difficult to degrade within 1000 years, affecting the soil structure; if it is burned, it will produce harmful gases and pollute the atmosphere.

Therefore existing straw blankets have been far behind the country's goal of vigorously promoting energy conservation, emission reduction, and environmental protection.

CN201947623U discloses a grass blanket, the bottom layer is a plastic isolation layer, and the isolation layer is laid with a matrix layer composed of natural plant fibers, organic fertilizers and nutrient soil, and the matrix layer is provided with a curved protective net. Grass seeds are added to the matrix layer. The protective net is metal net or polypropylene net. The beneficial effect of the utility model is that it can create suitable growth conditions for the vegetation in the environment with harsh climate conditions.

CN2212882Y discloses a grass blanket, which is characterized in that, on the non-woven cushion layer made of plant fibers, a mixed layer composed of seeds, fertilizers, water-absorbing agents and medicines is fixed and supported, and 100 % The seed protection fiber layer with a thickness of 0.5 to 2.0 centimeters made of rotten plant fibers, and the top is a tensile protection mesh layer with a rotten cotton thread or rotten plastic processed into a mesh of 1 × 1 centimeter.

CN92100044.8 discloses a kind of seed tape, it is characterized in that, the seed tape is to be connected together by cellulose fibers by intertwining and slight adhesion between each other, or water-soluble adhesive or viscous resin, which A non-woven fabric is cut into a tape and the seeds are wrapped in it, and a fiber filament that can decompose in the soil is wrapped on the seed tape by a seed tape production device.

Although the grass blanket disclosed above can grow under harsh conditions, is strong and durable, can create suitable conditions for vegetation to grow, has a simple structure and is easy to carry, but there are some defects at the same time: the existing raw materials use the discarded straw of natural crops, although it solves the problem of The environmental pollution of crops is not easy to store for a long time, it is perishable, and the process is complicated, the air permeability of the grass blanket is poor, the lawn is uneven after growing due to the different number of grass seeds, it is not resistant to trampling, and a large area of grass blanket is covered On the surface of the soil, an airtight plastic material is used as the base layer. Since the plastic is difficult to degrade in a short period of time, it will affect the soil structure, easily cause soil damage, and seriously affect the environment.
