Like fertilizers, pesticides and seeds, mulch is an important agricultural material, which plays an important role in "enriching rice bags and filling cabbage seeds", increasing agricultural production and increasing farmers' income. However, since the plastic film is a high-molecular compound polyethylene, which is a non-decomposable plastic, if it is not recycled in time after use, it will damage the soil structure and affect the growth of the root system of crops; the residual film left in the field will be blown to the front house by the wind The back, fields and treetops will affect the appearance of the village. Therefore, strengthening the scientific use and recycling of plastic film to prevent and control the "white pollution" of farmland residual film is of great significance for promoting the green development of agriculture.
Plastic film use and recycling laws stipulate that violations should be punished
Article 88 of the Law of the People's Republic of China on the Prevention and Control of Soil Pollution: In violation of the provisions of this Law, the producers, sellers and users of agricultural inputs fail to promptly recycle the packaging waste or agricultural films of agricultural inputs such as fertilizers, or If the pesticide packaging waste is not recycled in a timely manner in accordance with the regulations and handed over to a specialized agency or organization for harmless treatment, the competent agricultural and rural department of the local people's government shall order it to make corrections and impose a fine of not less than 10,000 yuan but not more than 100,000 yuan; If the person is an individual, a fine of not less than 200 yuan but not more than 2,000 yuan may be imposed.
Article 65 of the Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Wastes: Units and other producers and operators that generate agricultural solid wastes such as straws, discarded agricultural films, and pesticide packaging wastes shall take recycling and other measures to prevent environmental pollution. measure.
Article 6 of "Measures for the Administration of Agricultural Films": Prohibit the production, sale, and use of agricultural films that are explicitly prohibited by the state or that do not meet mandatory national standards. Encourage and support the production and use of fully biodegradable agricultural films. Article 15: Agricultural film users should pick up non-fully biodegradable agricultural film waste in the field before the expiration of the use period, and hand them over to recycling outlets or recycling workers, and shall not arbitrarily discard, bury or incinerate. Article 16: Agricultural film producers, sellers, recycling outlets, waste agricultural film recycling enterprises or other organizations should cooperate and adopt various methods to establish and improve the agricultural film recycling system, and promote the recycling of waste agricultural film, disposal and reuse.
Article 29 of the "Hebei Province Soil Pollution Prevention and Control Regulations": Prohibit the production, sale and use of agricultural inputs that are explicitly prohibited by the state and the province. Producers, sellers and users of agricultural inputs shall promptly recycle the packaging wastes and agricultural films of agricultural inputs such as pesticides and fertilizers in accordance with relevant national and provincial regulations, and hand over the packaging wastes of pesticides to specialized agencies or organizations for processing. Harmless treatment.
Actively use thickened high-strength mulch film and fully biodegradable plastic film
What is thickened high-strength mulch film?
It refers to the thickened high-strength plastic film with a thickness of more than 0.015 mm. Experts said that thickening high-strength mulch film has a good effect on heat preservation and moisture retention, which can promote crop production, and it is easier to pick up and recycle after use, which can ensure the recyclability of mulch film from the source.
How to use thickened high-strength mulch?
Suitable crops: vegetables, cotton, corn, etc.
Key points of field mulching technology: According to the regional climate characteristics and production actuality, each region should choose a reasonable mulching method and time, and focus on key links such as soil preparation and fertilization, ridge mulching, and timely and appropriate moisture sowing. According to product performance indicators, timely improve sowing, mulching and other supporting equipment and agronomic measures.
What is fully biodegradable mulch?
It refers to a film prepared with biodegradable materials as the main raw material, which is used to cover crops and has biodegradable properties. It has the characteristics of increasing production and quality, being environmentally friendly, and requiring no recycling for use.
How to use fully biodegradable mulch?
Suitable crops: potatoes, peanuts, garlic and other suitable crops with high economic benefits.
Key points of field mulching technology: It is advisable to choose a plot with convenient irrigation and drainage, sufficient water source and loose soil structure, and properly plough the land according to the moisture content at the time of planting, remove the crop residues and stones in the soil, ensure the smoothness of the soil surface, and avoid premature damage of the mulch film during the laying process. .
When the soil moisture content is suitable, the soil is prepared, and the rotary tillage is generally performed more than once. The organic fertilizer can be applied to the soil along with the rotary tillage operation to avoid the direct contact of the mulch film with the organic fertilizer.
When laying, the mulch film should be properly tensioned and close to the soil bed, and an appropriate amount of soil can be covered every 2 to 3 meters to prevent wind.
When using the drip irrigation system, try to avoid long-term contact with the drip irrigation tape when laying the mulch.
In arid areas, the frequency and amount of irrigation can be appropriately increased, and long-term water storage on the film should be avoided to prevent premature degradation of the plastic film.
After the mulch film is used, it should be recycled in time to protect the soil environment of the cultivated land
Main points of mechanical recycling technology of waste plastic film: After the crops are harvested, for the land leveling and mulching planting concentrated contiguous areas, use a single-type residual film recovery machine with appropriate width or a combined operation machine for straw crushing and returning to the field and residual film recycling;
For areas where film mulching is not concentrated and contiguous and the field area is small, a small single-type residual film recovery machine or a double-type combined operation machine is used;
Before sowing in the next season, recycling machinery such as spring-tooth type and rake type can be used to recover the residual film in the plough layer.
Scientifically use and recycle plastic film to protect the soil environment of cultivated land, benefiting the country, the people and everyone. Before the crops are planted and after harvesting, it is necessary to pick up and recycle the waste mulch film remaining in the cultivated land in time, and hand over the picked up waste mulch film to the relevant recycling outlets in time for later processing and reuse.
Use plastic film scientifically and rationally, actively pick up and recycle waste plastic film, control the "white pollution" of farmland, and promote the green development of agriculture!
