Application of plastic film in agriculture.

Application of plastic film in agriculture.

In agriculture fields, in order to protect the plant and prevent water from loss, farmers use plastic films as bedding, and with the rapid pace of agricultural development, which greatly increased the demand for plastic film, plastic film.

The survey found that in developed countries, agricultural plastic film is more than 50% of all the total with agricultural polymer products, China ranks first in the amount of agricultual film in the world, the demand for up to 150 million tons per year, and each year 15% speed increase.

Role: To promote crop growth.

Common agricultural and mainly polyvinyl chloride polymer, polyethylene, polypropylene, unsaturated polyester resins and the like. In recent years, plastic film showing two significant effects: heat and moisture, it has been widely used in agricultural production. For example, the production of plastic film greenhouses or greenhouses can carry rice, cotton and melons, fruits, vegetables, nursery and cultivation.

Carried rice seedlings with plastic film can save seeds, improve crop resilience. Because plastic shed temperatures, moisture suitable for germination and seedling growth of rice to prevent cold and cold, avoid birds pecking child to avoid Rot Simiao phenomenon, reaching food production. Plastic film can also be cotton breeding, cotton extend the growing season, increasing resilience, cotton seed saving, so brocade flower production. With plastic film melon, fruit, vegetables, nursery cultivation, production can only grow exponentially and can be an early market, improve the quality and extend the supply period.

Growing vegetables tend to be restricted by natural conditions, lower north, the annual average temperature in China, the cold season is generally difficult to eat fresh vegetables, plastic greenhouses north in the cold season can grow fresh vegetables, fresh vegetables extend the supply of rich people's food basket.

In addition, the plastic film can also prevent insects and frogs, germination, deterioration, etc. In winter, used to cover agricultural products stacked in the open so you can keep warm. Plastic film can also be stored fruits and vegetables, greatly extend the shelf life of fruits and vegetables, reduce economic losses due to decay caused. Visible plastic film to agricultural production brought no considerable economic value.
