1. Powdery mildew: 45% chlorothalonil in the early stage of the disease, 250-300 grams per 667 square meters in 4-5 in the shed, lighted in the closed shed for 1 night, the next morning ventilation, 7 days smoked 1 Second, depending on the condition, continuous smoking 3-4 times; the initial stage of the disease with 20% powder rusting emulsion 2000 times solution, or 40% sulfur suspension 600 times solution, or 50% sulfur suspension 250 times solution, or "agricultural resistance 120" 200 times Liquid spray; using 27% high-lipid film emulsion 70-140 times solution, sprayed on the leaves at the beginning of the disease, spray once every 7-14 days, even spray 3-4 times.

2, gray mold: smoking method with powdery mildew. It can also spray 1kg of 6.55% GM powder per 667 square meters, spray once every 7 days, and spray 2 times; spray 40% Shijiale Suspension 1200 times solution or 65% methicillin WP at the beginning of the disease 1000-1500 times liquid, or 70% methyl thiophanate WP 800 times solution. Spray once a day for 7 times and spray 2-3 times continuously. Pharmacy rotation is used.

3, downy mildew: smoking method with powdery mildew. It can also be sprayed with 5% chlorothalonil dust per kilogram of 667 square meters, sprayed once every 7 days, and even sprayed 2-3 times; 70% ethylphosphorus manganese zinc wettable powder 500 times solution is found after the central disease plant is found. Or 72.2% Plex aqueous solution 800 times solution, or 40% ethyl phosphorus aluminum wettable powder 200 times solution, or 64% anti-virus 矾 400 times liquid spray, 7-10 days spray 1 time, according to the development of the disease to determine the number of medications. It is also possible to use a sugar nitrogen liquid, that is, brown sugar or white sugar 1% + 0.5% urea + 1% vinegar + 0.2% ethyl aluminum phosphate, and spray the leaf surface once every 7 days.

4. Aphids: use 10% imidacloprid wettable powder for 5-16 grams per 667 square meters, or spray with 2.5% deltamethrin emulsifiable concentrate 1000-1500 times. When spraying, pay attention to even spraying on the back of the leaves; Use a smoke-killing agent, 400-500 grams per 667 square meters, dispose of 4 piles, ignite with a dark fire, and seal for 3 hours.

5. Whitefly: Spray with 10% imidacloprid or 3% acetamiprid WP 1000-1500 times.

Hearing aid manufacturers strive to optimize their wireless hearing aid offerings both in terms of connection reliability as well as power efficiency. Variance across patients and listening conditions can make optimizing wireless hearing aid systems a complex process.

Factors such as connection distance, proximity of reflective surfaces, interference from other wireless devices, and energy loss through body absorption must all be factored into the hearing aid design. For example, indoor wireless performance may be very different from wireless performance experienced outdoors, where the only reflective surface may be the ground on which the hearing aid user is standing. Furthermore, individual differences in body geometry increase the variability that wireless engineers must account for when designing a system that provides each user with a consistent and reliable experience.
