The basic technology of potato virus-free seed potato: first germination and disinfection of the poisonous potato in the room; then, under the aseptic condition of the clean bench, the shoot apex meristem is cut and transplanted in the test tube for cultivation, after about 4 months The shoot apical meristem grew into a test tube seedling; the test tube seedlings were tested for viruses, and virus-free virus-free seedlings were identified from a large number of plants; then they were cut through rapid propagation and propagated in greenhouses and net sheds to obtain detoxification. The micro-tubers or original species can be obtained by re-breeding, and the original species can be re-bred into a first-class seed potato, a second-class seed potato and a third-order seed potato, generally collectively referred to as a virus-free seed potato. Removed the major potato virus, restored the characteristics of the original species, to achieve the purpose of rejuvenation. Therefore, the detoxified potato has no virus, bacteria and fungal diseases within a certain period of time. Its viability is particularly strong, and the yield increase is very significant, generally increasing production by 30% to 70% or even doubling. As a result, the quality of the product is significantly improved, and rot, tip, crack, deformity, and sores that are easily caused by the planting of susceptible seed potatoes are greatly avoided. In addition, the transportation costs of seed potatoes are also significantly reduced. Due to the weight of virus-free mini-tubers only 2-5 grams, only 8-20 kilograms are used per acre.
Anti Bird Net
Anti Bird Net
Anti-bird net is a kind of polyethylene, high-density polyethylene, polypropylene and nylon which are added with anti-aging and anti-ultraviolet chemical additives. It is a kind of plastic woven mesh and anti bird net has the advantages of high tensile strength, heat resistance, water resistance, corrosion resistance, aging resistance, non-toxic and tasteless, and easy disposal of waste. It can kill common pests such as flies and mosquitoes. The conventional use of the collection is light, and the correct storage life can reach 3-5 years.
Bird-proof net cover cultivation is a new environmentally-friendly agricultural technology that increases production and practicality. It builds artificial isolation barriers on the scaffolding, rejects birds outside the net, cuts off bird breeding routes, and effectively controls various types of birds. Spread and prevent the spread of viral diseases. And it has the functions of light transmission and moderate shading to create favorable conditions for crop growth.
The bird-proof net also has the function of resisting natural disasters such as storm erosion and hail attack.
Beyond garden, the anti bird net also be used in airport, building, residential houses, etc.
