In 2017, the Qingdao Experimental Base in Fujian changed the plastic trays to non-woven fabrics

Non-woven fabrics replace plastic trays to raise tobacco seedlings online According to the Tobacco Institute of the Chinese Academy of Agricultural Sciences. Recently, the 2017 spring and summer tobacco planting work of the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences in Qingdao Test Base of Fujian Province was successfully completed, and a total of 3,000 kinds of test materials were arranged More copies. For seedling cultivation this year, one is to change the self-prepared substrate to purchase a special seedling substrate; the second is to adjust the support material of the seedling tray, and to change the plastic tray to a black non-woven fabric with heat insulation and air permeability; the third is to conduct a multi-batch and multi-environment preparatory test; New fungicides are used to disinfect the nursery greenhouse and nursery trays; the fifth is to use temperature and humidity sensors to monitor the nursery temperature and humidity in real time and take timely measures; the sixth is to maintain communication with the teams, strengthen management, and ensure that various technologies are in place. Through the close cooperation of the base management office and the relevant innovation team, this year's tobacco seedlings emerge quickly, fully emerge and grow strongly. Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of directional or random fibers. Non-woven fabric is a new generation of environmentally friendly materials. Non-woven fabrics are moisture-proof, breathable, flexible and light , Non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low price, recyclable and so on. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. Because non-woven fabric has the appearance and certain properties of cloth, it is called cloth.　　 Recently, the fake planting of spring tobacco has started one after another. In the next step, the base management office will do a good job in the management of the fake planted tobacco seedlings to ensure the smooth development of various scientific research work this year.
