The electric spraying technology believes in science and technology, changes the concept of spraying medicine, promotes traditional agriculture, moves toward modern agriculture, 1, traditional spray technology, and 2. What is the gap in technical requirements for the prevention and control of vegetable pests and diseases in China? 3, electric spray technology: 4, the function of electric ultrafine dust sprayer? 5, the effectiveness of new high efficiency ultrafine dust agent? 6, the technical content of electric spray technology? 1. What are the gaps in the technical requirements for the prevention and control of vegetable pests and diseases in China with traditional spraying techniques? The rapid development of the cultivation area of ​​protected vegetables in China in the past decade has led hundreds of millions of farmers to become a way to make a fortune, and has improved and improved the living standards of urban and rural residents in China. With the continuous development of protected cultivation areas, pests and diseases have become more and more serious. Facilities in the protected area: poor air flow, high temperature and humidity: crop cultivation density, large growth period, high plant height, dense leaves, severe planting and other factors. Especially low-temperature and high-humidity are important conditions for causing serious diseases. Traditional plant protection technology - characteristics of wettable spray agent technology: Wettable powder drug, generally valid for 6-7 days. The technical standard for medication treatment is: 6 days once, 3 consecutive treatment procedures. Dilution with water, degradation of drug efficacy, heavy weight on the back, easy contact with the skin of the medicine, short spraying time, long spraying time, and labor intensity. Spraying and spraying drugs to increase the humidity of greenhouses can easily lead to conditions conducive to the occurrence of germs. The control effect has dropped significantly. The protected cultivation has high density, long growth period, high plant height and many leaves, and the spray is large and impervious, failing to fully sterilize, causing the bacteria to invade many times. The rain, snow, and even the weather, the low temperature, the high humidity, and the prevalence of germs, cannot be applied by spray technology. At present, plant protection technology measures are generally adopted in our country's protected areas: the spray of sunny days, the use of aerosols in cloudy and rainy days, and the prevention of widespread dust agents, the law of spraying in sunny days. Disadvantages of these agents are: A. Spraying of water sprays: 1. Due to drug resistance, which is limited by a period of 6 to 7 days, our country's spray treatment takes “6 days once, 3 times in a row†as a treatment measure, resulting in people The timing of medical treatment was delayed, resulting in economic losses: multiple injections increased the cost of medication, increased labor, and reduced economic benefits. Rainy and snowy weather can not be sprayed with water or powder pesticides, resulting in disease-free prevention, disease can not be ruled, harvest can not be guaranteed, the result is the worst loss. B. Aerosols: C. Ordinary dust agents: They can only be prevented and cannot be treated. After spraying 2 or 3 times, the dust accumulation seriously affects the photosynthesis of crops due to the large amount of pesticides used, which results in a significant drop in crop yield. Due to the high cost of traditional plant protection technology, large cost, and poor results, in the current situation where pests and diseases in the protected areas are becoming heavier and the losses are becoming more and more serious, it has been impossible to guarantee the highest yield and highest efficiency of the vegetables in the protected areas. The traditional plant protection technology is lagging behind the development of protective cultivation techniques, which has become a limiting factor for the development of high-yield and high-efficiency vegetables in China. Therefore, what kind of plant protection technology is selected is not only efficient, provincial, provincial, but also effective. It is imminent to be able to cure vegetable pests and diseases once and for all. The electric spray is jointly developed by our company and China Ultra Micro Dust Research Institute. Technology>> solved this problem. 2. Dynamic spraying technology Electric spraying technology is the replacement technology of traditional manual spraying technology. Application within the protected area is more than a function. This technology has been highly evaluated by Prof. Li Mingyuan, a plant protection expert from the China Academy of Agriculture and Forestry Sciences. The electric spraying technology has reached the domestic advanced level and has filled a domestic gap. Electric spray technology is the application of "electric ultrafine dust sprayer" spray "new type of high and small micro-dust agent" prevention and control of various vegetable pests in the field of plant protection technology. This technology has the advantages of labor saving, provincial power, and provincial drug efficacy. The effective period is as long as 20 days or more. The application is not limited by weather conditions, and has the function of curing vegetable pests at a low cost and high efficiency. "Electric Ultrafine Dust Sprayer" and "New High-Efficient Ultrafine Dust Agent" complement each other and are inseparable, forming a new unified electric spray technology. 3, the function of electric ultrafine dust sprayer? "Electric Ultrafine Dust Sprayer" is a multi-functional spray and high-efficiency micro dust agent for special drug and lighting tools. The machine has reasonable structure, beautiful appearance, easy operation, high power and high efficiency. Function: The medical apparatus is suitable for various greenhouses, large and small sheds. The machine has a high rotational speed and a large air flow, which enables the ultrafine dust agent to float in space for a long time. The machine sprays evenly and covers a large area. 0.3-0.6 kilograms are used per mu of shed. The machine can regulate the height of crops and the degree of disease severity to adjust the dosage. Spraying only 5 minutes per acre. Ample electricity can spray 10 acres of room area. Spraying is not limited by weather conditions, and yin, rain, snow, and sunny weather can be sprayed and used. 4. What is the effectiveness of the new high-efficiency ultra-fine dust agent? The new type of high-efficiency ultrafine dust agent is China National Institute of Ultrafine Powders, which is specially developed and produced by the Bureau of Crop Diseases and Insect Pest Resistance and authorizes me to operate exclusively in the country. Efficacy: Significant effect, to cure vegetable pests again and again. Long time interval spraying: less use, less dust accumulation in leaves, does not affect the role of photosynthesis. Ultra-micro, floating capacity, penetrating ability, to achieve all-round control of crops. The high-tech formula does not cause aging of the leaves, and the leaves turn green after 5 days of spraying. Valid for more than 20 days. 5. Scientific and technological content of electric spraying technology 1. Rapid spraying, 2. Significant effect, 3. Achieving the goal of curing pests and diseases once. 4, no delay in treatment time. Minimize pest and disease losses. 5, the validity period of up to 20 days or more, 6, the interval of spraying a long time, 7, the cost of medication is lower than the cost of spraying. 8. The new high-efficiency ultra-fine dust agent contains various trace elements. 9. It can greatly increase crop yield. Practice has proved that electric spraying technology, prevention and control of diseases and insect pests in greenhouse vegetables significantly increase the yield of vegetables by more than 20%; the cost of medication is 25% lower than traditional spraying methods; spraying quickly improves ergonomics by 30 to 60 times compared to traditional spraying, greatly reducing Labor intensity has liberated labor productivity. The characteristics of electric spraying technology can be summarized as: low cost, high work efficiency, high output, and high efficiency.
