Vegetable greenhouse non-woven fabric factory helps the transformation and upgrading of the greenhouse planting industry

In the past, due to the high latitude and low winter average temperature in northern my country, open field cultivation was difficult due to low temperature restrictions under natural conditions. Winter Tibetan cabbage, potatoes, and radishes have become the main types of vegetables consumed by most residents in winter. Constrained by the lack of water resources and the large temperature difference between day and night, my country's high-altitude areas have been in short supply of vegetables and fruits for a long time. In recent years, with the large-scale promotion of gardening facilities such as solar greenhouses and plastic greenhouses in these areas, the shortage of winter vegetables and fruits and limited varieties have been greatly improved, and the local 'vegetable basket' and 'fruit plate' have been greatly improved. 'The balanced supply capacity of products guarantees the diversity of the people's fruit and vegetable consumption. Unlike the open-air cultivation of vegetables and fruits, which can only be concentrated from April to October, and is highly dependent on the weather and rain of the natural environment, the production of vegetables and fruits under the protection of solar greenhouses and plastic greenhouse facilities can basically achieve 'all year round'. Taking Qinghai Province as an example, after the large-scale development of facility agriculture, the types of vegetables have grown from crude vegetables to more than 20 varieties of pepper, broccoli, bean sprouts, bitter chrysanthemum, etc., and strawberries and grapes have been added to fruits. , Ginseng fruit, nectarine, watermelon, papaya, blueberry and more than a dozen varieties. From a national perspective, my country’s per capita vegetable consumption was 190 kg in 2014, of which facility vegetables accounted for 32.3%. Generally, non-woven fabrics for vegetable greenhouses are commonly used, and in use, they can ensure the growth temperature of greenhouse vegetables to a certain extent, thereby promoting their growth. Of course, in addition, this kind of greenhouse non-woven fabric also has better cold-proof and heat-preservation effects, which can effectively ensure the growth of crops, and it also has strong wind resistance, which can effectively ensure the stability of the greenhouse. . In addition, the greenhouse non-woven fabric can also be cultivated according to the different growing seasons of crops, thereby effectively improving its production efficiency. Non-woven fabrics are used in vegetable greenhouses. In addition to being used as packaging bags, packaging rice noodles and other foods, non-woven fabrics can also be used as a new type of covering and thermal insulation material. It is used as greenhouse thermal insulation in the production of vegetables in the greenhouse. Good insulation effect. Through vegetable farmers’ application practice, non-woven fabrics are used as a “second-pass” insulation material at the bottom of the grass thatch in the production of vegetables in the shed, which can significantly improve the thermal insulation performance of the shed, which is 2℃～3℃ higher than that of the grass thatch, which is beneficial Vegetables grow. In addition, the application of non-woven fabrics on the shed using the roller shutter machine can also protect the grass thatch and extend its service life. Use multiple non-woven fabrics to stitch together to wrap the entire back wall and fix it with steel wires to reduce heat loss from the back wall; it can prevent rain and snow and protect the wall; it can be covered and weeded to reduce pests and diseases entering the shed. The reason that my country's facility agriculture is large but not strong, and its efficiency advantages have not been fully demonstrated, has a lot to do with the low quality of key elements such as equipment, agronomy, and manpower. To promote the transformation and upgrading of facility agriculture and improve quality and efficiency, we must grasp the key link of improving the quality of elements. In terms of equipment, on the basis of the introduction of large-scale intelligent greenhouse facilities and technologies from abroad, the research and development of common key technologies and equipment for facility agriculture should be strengthened, and facility agriculture technology and equipment, especially covering materials, should be included in the national catalog of encouraging scientific and technological development as soon as possible. To produce high-end covering materials that can adjust temperature and optimize sunlight waves. Incorporate more key mechanical equipment that is conducive to the development of modern facility agriculture, especially those small and multi-functional sheds (rooms) that are suitable for the development of my country's facility agriculture, into the agricultural machinery purchase subsidy catalog in time, and encourage farmers to use advanced facilities and equipment . In terms of agronomy, strengthen the cultivation and promotion of good varieties with good quality, high yield and suitable for facility cultivation, focus on the integration of agricultural machinery and agronomy, and promote the application of new technologies such as straw reactors, green integrated prevention and control of diseases and insect pests, and resistance to continuous cropping obstacles. In terms of manpower, in accordance with the requirements of “scientific and technical personnel directly to the households, direct access to the fields with fine varieties and methods, and direct access to the technical essentials”, increase the training of facility agricultural planting techniques and field management techniques; improve labor training methods, where conditions permit By means of financial subsidies, etc., facilities agriculture trainees will be selected to develop facilities agriculture areas at home and abroad to train key talents for facility agriculture development. The non-woven fabric can be directly covered on the small arch shed in the arch shed, and the effect of heat preservation and cold protection is outstanding.
