Cucumber downy mildew, angular spot, and powdery mildew are the major diseases that cause cucumber production reduction. In order to reduce the pollution of chemical pesticides, pollution-free pesticides should be used as much as possible. The following describes several methods of preparation of pollution-free pesticides. First, black sugar M enzyme method Black sugar pesticide is a pollution-free cucumber pesticide, downy mildew, powdery mildew and other diseases. Its synthetic components do not contain toxic substances, can be absorbed through the leaves, enhance the physiological activity of the leaves, while increasing the effective bacteria, promote the photosynthesis of the leaves, create more adequate nutrients, so that plants have a stronger resistance to pathogens, Prevent the invasion of harmful pathogens. Its production method is: brown sugar (brown sugar can also be) 4kg, biological M enzyme 300g, boiling water 9kg, a clean porcelain jar (15kg load). The porcelain cans are first cleaned (preferably sterilized), dried, and the brown sugar is poured into a can, followed by boiling water to completely dissolve the sugar. When the soup temperature drops below 30°C, slowly add the enzyme and gently stir to make it fully mixed. Then, with a sterilized bleached cloth, seal the lid of the can, place it in a warm place (18-35°C), stir once a day, and add the appropriate amount of vinegar in the first stirring (about 5mL). ), 5--10d fermentation foam. With the continuous production of new bodies and the polymerization of enzymes, the white spots on the surface of the nutrient solution appear first and a layer of white film is formed. This results in a black sugar pesticide solution, which has a potency of 3 months and can be placed in a cool shade. Stored, diluted 1000 times when sprayed. Second, sugar, wine, vinegar, M enzyme, sugar, wine, vinegar, pesticides can control a variety of diseases and insect pests of cucumber. It can also prevent fruit star disease and scab. The production method is simple and effective. Production method Mix the AM bio-agent stock solution (product of Gansu Dasheng Bio-Engineering Institute), brown sugar, white wine (above 30°C), vinegar, and water in a ratio of 1:1:1:1:10 and mix the liquid. In a polyethylene plastic container, close the lid and put it in room temperature fermentation. Confirm that the temperature of the solution does not exceed 40°C. After a few days, the fermentation broth will generate gas and the container will bulge. Then, the lid needs to be loosened, the gas released, and then the lid tightly closed immediately. After the first gas generation, the gas needs to be placed every 3 days or so. If the gas is no longer generated, it means that the fermentation has been completed and a pungent odor can be smelled. The fermentation time is about 15 days in summer and 20-30 days in winter. Sealed at room temperature for 2 to 3 months. If the smell of vinegar disappears, it means that it has failed. The standard dilution of pest control fluid is 1000 times. If the effect is not obvious after spraying, the dilution ratio can be gradually increased to 50-200 times, and the young leaves and seedlings should not be lower than 800 times. Both sides of the leaves, young stalks should be sprayed. The most basic purpose of using the formulation liquid is to prevent the occurrence of pests and diseases, and it should be used as soon as possible. If pests and diseases occur in large quantities and then used, the effect is not ideal. Third, urine sugar in the growth of cucumber in the late, if the poor fertility, growing weak, there will be symptoms of malnutrition. It has been reported that the ratio of nitrogen sugar concentration in the sap of cucumber plants decreases to 2 or less, and downy mildew is prone to occur; if the ratio of sap concentration is increased to more than 2.2, the occurrence of downy mildew can be prevented. According to tests, disease-resistant varieties have high sugar content, while susceptible varieties have low sugar content. Therefore, some people also called downy mildew disease "low sugar." Thus, through nutrition supplements, prevention and control can be achieved. According to the test, urea 0.2kg + sugar (white sugar, brown sugar can be) 0.5kg + water 50kg. During the prosperous period, spray once every 5 days, spray 4 to 5 times continuously, and the control effect is about 80%. It is usually sprayed in the morning, sprayed on the back of leaves, and used on susceptible varieties. China Agricultural Network Editor
Air Purifier
Dynamic disinfection is a process of disinfection and cleaning of air and surfaces in indoor Spaces. A
new method of safe disinfection that does not cause harm or interference to people and the environment on
site.The charged particles and active oxygen components produced by the low-temperature plasma in the
equipment play a major role in the process of killing bacteria and viruses, and have the effect of
broad-spectrum sterilization. It can not only inactivate aerosol plankton in the air and bacteria
and viruses on the surface of object but also effectively decompose formaldehyde and volatile organic
compounds, degrade all kinds of bad smell and purify it Air environment.A small amount of high purity
zone.
Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to decoration pollution that can absorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc. , bacteria, allergens, etc.), household appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.
There are many different technologies and media in air purifiers that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructured photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Carbon core filter technology, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are used at the same time.
