The new pp non-woven mulch film has a bright future in modern agriculture

For the research and development of biodegradable mulch materials, PP non-woven materials have been applied to agricultural production in some European and American countries and Japan. PP non-woven fabric is a new generation of environmentally friendly materials. It has the characteristics of good strength, breathability, strong toughness, non-toxic, odorless, non-combustible, etc., and can be changed by adding water-repellent or hydrophilic materials to change its different water characteristics to adapt to The production requirements of materials in different occasions can be flexibly changed to meet the production needs of different environments such as in the shed or outdoor field.


Non-woven materials are degradable materials and can be recycled. They do not release harmful gases when burned, nor do they have any leftover substances. They are internationally recognized as environmentally friendly products that protect the earth's environment. In developed countries, non-woven materials have long replaced plastic films in agricultural production.


Aiming at the application of non-woven materials in agriculture, Qingdao Agricultural University and Qingdao Wonong Modern Agriculture Co., Ltd. jointly developed a pp non-woven mulch film. The manufacturing process of ordinary non-woven fabrics is improved, and a patented formula for the production of agricultural non-woven fabrics is formed, so that it is breathable, water-permeable, weed-proof, and has a controllable service life. Experiments and promotion were carried out in Weihai, Yantai, Qingdao and Beijing in Shandong, and the effect was very obvious.


Non-woven mulch film can inhibit the growth of weeds, thereby reducing the cost of labor for weeding and the impact of the use of herbicides on the ecological environment of the orchard. Experiments have shown that the black non-woven fabric has the best weeding effect. When the grass seeds germinate, due to the extremely low light transmittance of the black non-woven fabric, the unearthed weeds can hardly receive the sunlight, which directly leads to the failure of photosynthesis. The effect prevents weeds from normally synthesizing organic matter necessary for life activities and eventually die.


The thermal and moisture resistance of a non-woven fabric is mainly determined by its thermal resistance and moisture resistance. It depends on its thickness, the number of pores per unit area and the size of a single pore. The ability to absorb heat is mainly determined by the color of the surface of the non-woven fabric. By changing the above factors, the effect of increasing temperature and maintaining humidity can be achieved. At the same time, the biggest difference from PVC mulch is that non-woven fabric is breathable, which can maintain good respiration of fruit tree roots, promote root growth and metabolism, and prevent Root rot and other problems caused by anaerobic respiration.


For the orchard covered with black non-woven mulch, the ground temperature can be increased by 2-3°C due to the large amount of light radiation absorbed by the non-woven fabric and the effect of heat preservation. When the outside temperature is low in early spring or late autumn, the ground temperature can be increased significantly Promoting the life activities of the root system can not only increase the growth of the root system, but also maintain the absorption of water and inorganic salts by the root system and the storage rate of root organic matter. At the same time, the increase in ground temperature can also extend the activity time of microorganisms in the soil, increase the decomposition and release of nutrients, effectively improve the nutrient absorption level of fruit trees, and provide sufficient nutrients for fruit trees to survive the winter safely and grow in the following year.


The use of non-woven fabrics on the surface of the orchard can not only increase the soil temperature, but also effectively maintain the soil moisture, to a large extent, reduce the adverse effects of dry natural weather on the growth of fruit trees, and at the same time reduce watering The frequency and the change of soil moisture are relatively gentle, which is conducive to maintaining a good growth environment for fruit trees and enhancing resistance to diseases.


pp non-woven mulch film has the advantages of traditional mulch film, such as temperature raising, moisture preservation, and weed control, and has the unique advantages of air permeability, water permeability, and degradability, plus its simple manufacturing process, controllable service life, environmental protection and no pollution There will be broad development and application prospects in modern agriculture
