Agricultural film, as an important material indispensable to agricultural production, to improve crop yield and quality, enhance the market competitiveness of agricultural products has a pivotal role. However, there are many types of agricultural film on the market, the quality of good and bad, how to correctly buy agricultural film has become a problem of concern to the majority of farmers. In this paper, from the types of film, performance, purchase skills and the use of precautions, etc., for the majority of farmers to provide a practical guide to the purchase of agricultural film.

First, understand the types of film

Agricultural film is mainly divided into plastic film, non-woven fabrics and biodegradable film and so on. Among them, plastic film is one of the most commonly used, with good heat preservation, moisturizing, pest control, weed control and other functions. Nonwoven fabrics, on the other hand, are used in some special planting needs due to their good air permeability and durability. Biodegradable film is a kind of environmentally friendly agricultural film, can be gradually degraded under natural conditions, reduce the pollution of the environment.

Second, grasp the performance indicators of agricultural film

When choosing agricultural film, farmers need to pay attention to the following performance indicators:

1. light transmission: the light transmission of agricultural film directly affects the photosynthesis and growth and development of crops, so the purchase should choose a good light transmission performance of agricultural film.

2. thermal insulation: the thermal insulation performance of agricultural film determines the growing environment of crops, should choose the appropriate thermal insulation performance according to the local climatic conditions when purchasing.

3. Durability: the durability of agricultural film is directly related to the service life and economic benefits, when buying should choose stable quality, durability of the product.

4. environmental protection: with the improvement of environmental protection consciousness, more and more farmers began to pay attention to the environmental performance of agricultural film. Selection should choose biodegradable, non-polluting environmentally friendly agricultural film.

Third, the purchase of agricultural film skills

1. Look at the packaging: regular manufacturers of agricultural film packaging will be marked with product name, specifications, production date, shelf life and other information, farmers should carefully check the packaging when shopping to ensure that the purchase of regular products.

2. Touch texture: high-quality agricultural film feels smooth, soft, with a certain degree of elasticity. The poor quality of agricultural film is rough, hard and brittle, easy to tear. 3.

3. Smell: regular manufacturers of agricultural film in the production process will strictly control the quality of raw materials, so made of agricultural film odor is small. While low-quality agricultural film may be made of poor-quality raw materials, the odor is larger, and may even have a pungent odor.

4. Stretch test: stretch the film to a certain degree and then release it to observe its retraction. High-quality agricultural film retraction is good, while poor-quality agricultural film is poor retraction, easy to deformation.

Fourth, the use of agricultural film precautions

1. Reasonable laying: make sure the ground is smooth and free of debris when laying the agricultural film, and reasonably adjust the laying angle and tightness according to the demand of crop growth. #Agricultural film recycling#
2. Timely Replacement: Agricultural film will gradually deteriorate and break during the process of use, farmers should check and replace the damaged agricultural film in time to ensure its normal function.

3. Scientific management: In the process of using agricultural film, farmers should adjust the management measures according to the growth of crops and climatic conditions, such as timely ventilation and watering.

4. Recycling: For the abandoned agricultural film, farmers should actively recycle it to reduce the impact on the environment.

In summary, the correct purchase of agricultural film is important for improving agricultural production efficiency and protecting the environment. The majority of farmers in the purchase of agricultural film should fully understand the types of agricultural film, performance indicators and purchase skills, and pay attention to scientific management and recycling in the process of use. Only in this way can ensure that the purchase of high-quality, environmentally friendly agricultural film for agricultural production to provide strong protection.
