1. What is the gap between traditional spraying technology and technical requirements for prevention and control of vegetable pests and diseases in protected areas in China?
The rapid development of cultivated area of ​​protected vegetables in China in the past decade has enabled hundreds of millions of farmers to move towards becoming rich, improving and improving the living standards of urban and rural residents in China. As the cultivated area of ​​protected areas continues to develop, the occurrence of pests and diseases is becoming more and more serious.
In the protected area facilities: poor air mobility, large temperature and humidity: large crop cultivation density, large growth period, high plant height, dense leaves: serious cultivation and other factors. In particular, low temperature and high humidity are important conditions for causing serious diseases.
Traditional plant protection technology - characteristics of wettable water spray technology:
Wettable powder medicines are generally valid for 6-7 days. The technical standard for treatment of medication is: once every 6 days, for 3 consecutive treatment procedures. Adding water to dilute, degrading the drug effect, carrying heavy weight, the syrup is easy to contact with the skin, the spraying time is short, the spraying operation time is long, and the labor intensity is large. Spraying drugs to increase the humidity in the greenhouse is easy to cause conditions that are beneficial to the pathogens. The control effect has dropped significantly. The protected cultivation density is large, the growth period is long, the plants are high, the leaves are many, the spray is large and impervious, and the whole sterilization is not achieved, causing the bacteria to infect again. Rain and snow are cloudy, the temperature is low, the humidity is high, the bacteria are easy to be popular, and the spray technology cannot be applied.
At present, plant protection technical measures are generally adopted in China's protected areas: sunny spray treatment - the use of aerosols in the rainy and snowy weather, the general dust prevention - the law of sunny re-spraying.
Disadvantages of a kind of medicine a, water spray:
1. Wet powder medicine due to the drug-reducing period of 6-7 days, China's spray treatment takes "6 days, 3 times in a row" treatment measures, causing people to delay the treatment of the disease, resulting in economic losses : Multiple spraying has 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 and preventable disease, disease can not be cured, harvest can not be guaranteed, the result is the most serious loss.
b, aerosol:
c, ordinary dust agent:
It can only be prevented, can not be treated, and after spraying 2~3 times, due to the large amount of drug, the accumulation of dust seriously affects the photosynthesis of crops, and the crop yield is greatly reduced.
Due to the high cost, large cost and poor effect of traditional plant protection technology, under the current situation that the pests and diseases of the protected areas are getting heavier and the losses are getting larger and larger, it is impossible to guarantee the highest yield and the highest benefit of the vegetables in the protected areas. Traditional plant protection technology is lagging behind the development of protected cultivation techniques, and has become a limiting factor for the high-yield and high-efficiency development of protected vegetables in China. Therefore, what kind of plant protection technology is chosen, which saves effort, saves effort, saves medicine, and has remarkable effects. It is urgent to achieve a cure for vegetable pests and diseases. Our unit and the China Institute of Ultrafine Dust Institute jointly developed the electric spray. Technology>> solve this problem.
2. Dynamic spray technology The electric spray technology is a new generation technology of traditional manual spray technology, and it has more transcendence functions in the protected area. This technology was highly praised by Professor Li Mingyuan, a plant protection expert of the Chinese Academy of Agricultural and Forestry Sciences. The electric spray technology has advanced domestic level and filled a domestic gap.
The electric spray technology is a new plant protection technology that uses the "Electric Ultrafine Dust Sprayer" to spray "New High and Small Ultrafine Dust" to prevent and control various vegetable pests and diseases in the protected area.
The technology has the advantages of labor saving, labor saving, and remarkable drug-saving effect. The effective period is more than 20 days, and the application is not restricted by climatic conditions. It has the function of curing vegetable pests and diseases, low cost and high efficiency.
"Electric ultra-fine dust sprayer" and "new high-efficiency ultra-fine dust" complement each other, inseparable, forming a new unified electric spray technology.
3. What is the function of the electric ultra-fine dust sprayer?
"Electric Ultrafine Dust Sprayer" is a special medicine and lighting tool for multi-functional spraying of high-efficiency ultra-fine dust. The machine has reasonable structure, light and beautiful appearance, easy operation, high power and high efficiency.
Features:
The medical device is suitable for all kinds of greenhouses and large and small arches. The high speed and large airflow of the machine enable the ultra-fine dust to float in space for a long time. The machine sprays evenly and covers a large area. The dosage of each shed is 0.3~0.6 kg. The machine can adjust the dosage of the crop height and the severity of the disease. It takes only 5 minutes to spray each acre. Ample electricity can be sprayed on the shed area of ​​10 acres. Spraying is not restricted by climatic conditions, and weather such as yin, rain, snow, and clear can be sprayed.
4. What is the efficiency of the new high-efficiency ultrafine dust?
The new high-efficiency ultra-fine dusting agent is China's ultra-fine dusting agent research institute. It specializes in the development and production of crop pest and disease resistance and authorizes me to have no exclusive operation in the country.
efficacy:
The effect is remarkable, and the vegetable pests and diseases are cured once. Long spray time: less use, less accumulation of leaf dust, does not affect the photosynthesis. Ultra-miniature, large floating capacity, strong penetrating ability, to achieve all-round control of crops. The high-tech formula does not age the leaves, and after 5 days of spraying, the leaves turn green. Valid for more than 20 days.
5, the scientific and technological content of electric spray technology 1, rapid spraying, 2, significant effect, 3, to achieve a purpose of curing pests and diseases.
4, do not delay the timing of treatment. Minimize pest and disease losses. 5, the effective period of up to 20 days, 6, the interval of spraying time is long, 7, the cost of medication is lower than the cost of spraying. 8. The new high-efficiency ultra-fine dust contains a variety of trace elements, 9. It can greatly improve crop yield.
Practice has proved that the electric spraying technology can significantly improve the vegetable yield of greenhouse vegetables by more than 20%; the cost of medicine is reduced by 25% compared with the traditional spraying method; the spraying speed is 30~60 times faster than the traditional spraying, which greatly reduces the efficiency. Labor intensity has liberated labor productivity.
The characteristics of electric spray technology can be summarized as: low cost, high work efficiency, high output, high efficiency.
