Buy plastic film to prevent white pollution
Because mulching has the functions of increasing temperature, keeping water, conserving fertilizer, improving soil physical and chemical properties, increasing soil fertility, inhibiting weed growth, and reducing disease, it also has the function of reducing humidity under continuous rainfall conditions, thereby promoting plant growth and development. Early flowering results, increase production, reduce labor costs and so on. In recent years, the use of mulch-covered crops has increased year by year, and the annual use of plastic film has increased rapidly. However, in order to save costs, many farmers' friends purchase ultra-fine membranes that are strictly forbidden to use. After they are laid, they will form small fragments one by one under the irradiation of sunlight. They are not easily recycled, causing residues in the fields and forming large areas of white pollution. With the continuous increase of plastic film residues, they are buried in the ground when they are cultivated and it is difficult to remove them. Many farmers have to plant crops on the garbage dump. Relevant experts pointed out that this status has exceeded the upper limit that can be tolerated by farmland ecological environment. If it does not speed up governance, it will further deteriorate. To this end, CCTV conducted special reports today.
Therefore, the majority of farmers’ friends must choose mulches according to regulations. The state has strict regulations on the thickness of mulch, the thickness of mulch is 0.014mm, the thickness of microfilm is 0.008mm, and the thickness of ultrafine film is 0.005mm. The standards recently promulgated by the state are strictly prohibited. The use of a plastic film of less than 0.008 mm, that is to say ultrafine membranes, is forbidden. The first consideration for this is the problem of white pollution, because the price of too-thin plastic films is reduced, but it can cause serious white pollution.
