The light transmittance of the anti-aging spunbonded nonwoven film decreases with the increase of the thickness of the film. The light transmittance of 16g white spunbonded nonwoven film is about 85.6%, while only about 60% of 30g white spunbonded nonwoven film. The permeability of the spunbonded nonwoven film decreases with the increase of the thickness of the film, and increases with the increase of the external wind speed and the increase of the internal and external temperature difference.
The testing pilot results of the Ministry of Environmental Protection indicate that rural surface water is slightly polluted, with a soil sample exceeding the standard rate of 21.5%. The pollution of farmland and vegetable soil is relatively serious. After covering with plastic film and reducing the use of fertilizers, the natural environment of the soil can be restored, the water and gas storage capacity can be improved, and the permeability can be greatly improved, which can effectively prevent the occurrence of root rot, wilt, and viral diseases.
Reducing the use of fertilizers and pesticides in plastic film will greatly reduce the content of nitrite, heavy metals such as lead, arsenic, cadmium, chromium, and mercury in the soil. The produced agricultural products contain very few nitrite, heavy metals, and are far below the residue standards of Japan, the United States, and the European Union. The production process does not add any hormones or regulators, thus ensuring the safety of food.
After covering with plastic film in early spring, it can prevent the emergence of pests that often overwinter in the soil under trees, prevent and reduce the reproduction and infection of pathogens that harm fruit trees in the soil, thereby preventing and reducing the occurrence and development of pests and diseases. In addition, plastic film covering improves the environment for root growth, making the tree robust and greatly enhancing its disease resistance
Rice seedling cultivation covered with spunbond non-woven plastic film has solved the problem of high yield caused by dead seedlings and rotten roots of rice
Corn has solved the problem of not spraying herbicides and not growing grass in corn fields: herbicides have a great destructive effect on the soil, and for the sustainable development of agriculture, it is always necessary to avoid using herbicides. The method of not growing grass is to plant corn in the stubble field after wheat harvest and cover it with spunbond non-woven plastic film, which is both environmentally friendly and high-yield
Cotton has solved the problems of falling buds and flowers, not setting peaches, and low yield caused by cotton overgrowth: cotton overgrowth is caused by excessive topdressing, water and fertilizer imbalance, cotton overgrowth is caused by overgrowth, and there are also pest factors. Falling flowers are caused by flowering, rain, and water entering the stamens. Only when the cotton tree is strong and long can it achieve non flourishing, non falling buds, and non falling flowers. By using film covering technology, we can reduce the use of fertilizers and achieve higher yields.
Peanuts solve the problem of insufficient flower growth and low yield, as well as the harm of white grubs and high pesticide residues caused by irrigation. Peanuts are crops with rhizobia, which fix nitrogen in the air. There is no need for fertilizer at all. The reason why peanuts are not fully grown is due to leaf spot disease and early defoliation. The defoliation is caused by spraying "paclobutrazol". Therefore, as long as you apply fertilizer, peanuts will flourish, and spraying "paclobutrazol" to control their growth. If you spray "paclobutrazol", peanuts are prone to leaf spot disease. If you get leaf spot disease, they will begin to fall. Peanuts with a growth period of more than 150 days will die of early defoliation in less than 120 days, How can peanuts grow full? The way to make peanuts grow full is; After wheat harvest, spunbonded non-woven fabric film is used, which has high yield and good quality.
Soybeans have solved the problem of low yield, non podding, and non seed bearing in soybean plants. Soybeans are also nitrogen fixing crops with rhizobia, which are prone to vigorous growth when applied with fertilizers. In addition, their high density can easily lead to situations such as lack of sunlight, non podding, and non seed bearing. This is also related to fertilizer and water imbalance. Only by covering with spunbond non-woven fabric film to make it strong and strong can it inhibit its growth
After reducing the use of fertilizers, agricultural products such as grains, cotton, oil, melons, fruits, vegetables, tobacco, tea, and meat, eggs, and dairy products contain extremely low levels or no longer contain carcinogenic or pathogenic toxins. In addition, the breathing air is clean, thus protecting future human health.
