Non-woven felt mulch has many advantages and is suitable for replacing ordinary mulch
Ordinary plastic film has many disadvantages:
Agricultural plastic film has been widely used in fruit tree greenhouses, open field fruit tree cover, etc. Agricultural mulch has the functions of moisturizing, heat preservation, insect resistance, disease prevention, and weed growth inhibition, which is beneficial to the growth and development of fruit trees, improves the yield of fruit trees, and improves the efficiency of fruit industry, and plays a pivotal role in modern agricultural production.
The wide application of agricultural film mulching technology not only promotes the development of fruit production, but also causes great pollution to China's ecological environment. The application of white mulch film needs to spray herbicides to prevent weeds; although black mulch film can play a role in weeding, it also pollutes the environment, and is easy to be weathered and damaged, and the weed control effect is not ideal. Moreover, both mulches have the problem of poor air permeability, which is not conducive to the normal growth of fruit tree roots.
Non-woven felt mulch
Non-woven felt mulch is a new generation of environmentally friendly materials, which are degradable materials, and can be recycled. There is no residual material, and it is internationally recognized as an environmentally friendly product that protects the earth's environment. It has the characteristics of good air permeability, strong toughness, non-toxic, odorless, and non-combustible, and can be adapted to different occasions by adding water-repellent or hydrophilic materials to meet the production needs of different environments such as sheds or outdoor fields.
Aiming at the application of non-woven felt materials in agriculture, the manufacturing process is improved to make it breathable, water-permeable, weed-proof, and controllable in service life. This year, the application experiment was carried out in the southern mountainous area of u200bu200bJinan, and the weeding effect was very obvious.
Felt mulch film can inhibit the growth of weeds, thereby reducing the labor cost of weeding and the impact of herbicides on the ecological environment of orchards. Through experiments, the weeding effect of covering the non-woven felt mulch film is very good. When the grass seed germinates, due to the extremely low light transmittance of the non-woven felt, the unearthed weeds can hardly receive sunlight. Photosynthesis fails to synthesize organic matter necessary for life activities, and eventually dies. Due to the heavy rainfall in summer this year, grass has become a headache for many fruit tree growers, especially near the trunk. If there is no covering, manual weeding is required 4-5 times. Grass does not grow in the early stage of black plastic film, and after the film is damaged in the later stage, In the case of long grass, if the non-woven felt mulch is covered, grass grows only in the place where the coverage is not strict or when the soil is covered, and it needs to be removed manually 1-2 times. It is worth noting that the malignant weeds growing between the rows should be removed while the fruit trees are covered. When the remaining weeds grow to 50 cm, the grass should be manually or mechanically mowed in time, and the grass should be mowed 3-4 times a year, which is very useful for soil improvement. help.
Compared with plastic mulch, the color non-woven felt mulch has better air permeability, can maintain good respiration of fruit tree roots, promote root growth and metabolism, and prevent root rot caused by anaerobic respiration, etc. problem.
Because of the large amount of light radiation absorbed by the colored felt and the effect of heat preservation, the ground temperature of the orchard can be increased by 2-3℃. When the outside temperature is low in early spring or late autumn, the increase of ground temperature can significantly promote the vitality of fruit tree roots, enhance root growth, and maintain the absorption of water and inorganic salts by roots and the storage rate of root organic matter. At the same time, the increase of ground temperature can also prolong 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 the safe wintering of fruit trees and the growth of the next year.
At the same time, the orchard covered with non-woven felt mulch film can effectively maintain soil moisture, reduce the adverse effects of drought on the growth of fruit trees, reduce the frequency of watering, and the range of changes in soil moisture is relatively flat. It is beneficial to maintain a good growth environment for fruit trees and enhance resistance to diseases.
Designed and colored non-woven felt mulch film has the advantages of traditional mulch film, such as temperature raising, moisture retention, weed prevention, etc., and has the unique advantages of air permeability, water permeability, and degradability. In addition, its manufacturing process is simple and its service life is controllable. , Environmental protection and pollution-free, and the price of non-woven felt manufacturers is low, there will be broad development and application prospects in modern agriculture.
