The fruit tree is used several times a year to kill the fungicide . Since someone asks, see how the experts answer:
Each fruit tree is different, and even a big tree is not the same. Different areas of prevention and control are different. This asks the wife to be general.
The main common pathogens of apple trees are: deciduous diseases (including: spotted leaves, brown spots, round spots, etc.), and the fruits are harmful to anthrax and mildew.
When the flower falls 70%-80%, it is a critical period for controlling diseases such as anthrax and mildew. The main drugs are: phenidazole, mancozeb, propidium zinc, carbendazim, thiophanate-methyl;
The first time to control the fallen leaves was in June, the weather gradually turned hot, and the pathogens began to harm the fruit trees. This period can be prevented by Bordeaux mixture. After about 20 days, use mancozeb, tebuconazole, and carbendazim. Also prevent Red Spider!
The weather in each place, the planting structure is different, and the management plan is different. The specific situation can be discussed together!
In the spring, the clearing garden is usually in the first half of the germination, and the reddish period of the flower is red. The spraying of about 80% of the flowers is started for 3 consecutive times, with an interval of 7-10 days, and then the bagging begins. It is generally not necessary to use emulsifiable concentrate before bagging, and generally powder is not used. They are all high-grade fungicides. The management after bagging is relatively extensive, and the difference is also large depending on the region.
Apple usually takes 10-12 times a year. According to the situation, 11 times of medicine is normal. They are: dry branches (dormant period). In mid-to-late March, the red stage of flowering (mid-April) is three times for bagging ( From the beginning of May to the beginning of June, the mid-May of May, the 20th day after the Xiehua, the late 2-3 days after the Xiehua in the late May, the 2-3 days before the bagging, the bag is usually 5-6 times after the bagging. Once again
The working principle of a Medium Flow Peristaltic Pumpis like a snake swallowing an egg. The hose is constantly squeezed through the roller to make the hose generate pressure and push the liquid forward. Our designers make the Peristaltic pump head and hose fit perfectly by designing precise roller size and pump head structure. So as to achieve the purpose of accurate liquid metering transmission or filling
1. Clean and pollution-free: the fluid only passes through and touches the Peristaltic Pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. With stop valve function, no siphon, no seals, stop valve and check valve function.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
