New pp nonwoven mulch in the modern agricultural development prospect

For biodegradable plastic materials research and development, and in some European and American countries and Japan have begun to PP non-woven material was applied to agricultural production. PP non-woven fabric is a new generation of environmental protection material, has good strength, air permeability, high tenacity, non-toxic, no smell, no combustion characteristics, and can be by adding the repellent or hydrophilic material to change its different characteristics of water so as to adapt to different situations of material production requirements, at the same time can be changed through flexible production process to meet the relative or outdoor field of different environments, such as the production requirements. Non-woven materials belong to biodegradable materials, and can be recycled use, don't release harmful gases during burning, also do not have any left over material, is internationally recognized as protect earth's environment environmental protection product. In developed countries, non-woven material instead of plastic film used in agricultural production early. For non-woven materials applied in agriculture, Qingdao agricultural university and Qingdao WoNong modern agriculture co. , LTD. Jointly developed a pp nonwoven mulch. For ordinary non-woven fabric manufacturing process was improved, and formed the production of agricultural non-woven patent formula, make its have breathable, waterproof, prevent grass, use fixed number of year under control. And in the shandong weihai, yantai, Qingdao, Beijing and other regions has carried on the experiment and the promotion, the effect is very obvious. Non-woven fabric membrane can inhibit the growth of weeds, thereby reducing the labor costs of used for weed control costs and the use of herbicides to orchard ecological environmental impact. Experiments show that the best weed control effect of black non-woven fabric, after the grass seed germination, due to low light transmittance of black non-woven, unearthed weeds can hardly accept the illuminate of sunshine, preventing this directly lead to the photosynthesis, make weeds cannot normal activities necessary to organic synthesis of life and eventually death. Non-woven insulation moisturizing ability of main size is determined by its thermal resistance and moisture resistance, depends on its thickness, pore number per unit area and single pore size, the ability to absorb heat is mainly decided by non-woven surface color, can do so by changing the above several factors to improve the effect of temperature and humidity, at the same time and the largest PVC film is different, non-woven fabric with air permeability, can maintain the root respiration, promote the growth of root system and metabolism, and prevent caused by anaerobic respiration and root rot, etc. For orchard covered black non-woven membrane, because the non-woven fabrics absorb light radiation and heat preservation effect, can make the ground temperature increase 2 - 3 ℃, in the early spring or late autumn outside temperature is low, the improvement of ground temperature can significantly promote the root of life activity, which can increase the root growth, root to water and to maintain the base of the absorption of inorganic salts and organic matter storage rate. Ground temperature at the same time improve can also extend the soil microbial activities within time, increasing the amount of decomposition and nutrient release, effectively improve the level of the fruit tree nutrition absorption, for fruit trees safe wintering provide sufficient nutrients and the growth of the next year. Orchard surface using non-woven fabric cover in improving soil temperature at the same time, also can maintain soil moisture effectively, to a great extent, alleviate the nature of the dry weather produced adverse effect on fruit tree growth, at the same time can reduce the frequency of the water, soil moisture content change relatively gentle, is beneficial to maintain good growth environment, enhance resistance to disease. Pp nonwoven mulch with traditional film temperature, keep moisture, prevent the advantages, such as grass and breathe freely, the distinct advantage of the permeable, biodegradable, and it has simple manufacturing process, use fixed number of year controllable, environmental protection no pollution, in the modern agriculture will have wide development and application prospects
