1. Advantages of dust application
Led solar wall lights have the following advantages:
1. Definition of solar wall light
7. Safety. The output power of the solar wall light is completely determined by the solar battery pack, while the output of the Tianyang solar battery pack depends on the temperature of the solar surface, that is, the intensity of the sun. The standard output of solar cells per square meter is about 120 W. Considering the panel area of the solar wall lamp, it can be said that its output voltage is very low, and it is an absolutely safe light.

(1) Control effect The dust has a long time, uniform distribution and good adhesion. The granules can be deposited in various parts of the plant, and can spread to the hidden parts of the plant. Even if the protected area is not tightly sealed, it will not affect the prevention and control. effect.
The operation is convenient, labor saving, time saving and medicine saving. No need to add water to the powder spray, it is not restricted by the water source, the spraying time is short, and the interval between medications is long, the medication is less, and the utilization rate of pesticides is higher.
(2) Improved farmland microclimate The conventional spray method uses a large amount of water, which increases the humidity of the air inside the protected area, resulting in aggravation of the disease. If the aerosol fumigation method is used, the medicament is easily decomposed at a high temperature to reduce the efficacy, and harmful gases are generated during the combustion process, which is not conducive to vegetable growth. The dust method does not increase the humidity in the shed, and the requirements for the sealing conditions of the protected area are not strict. It is allowed to prevent suitable diseases and pests while creating suitable environmental conditions, which is conducive to the healthy growth of vegetables.
2. Dust-applied agents are selected in the shed room. The common dusting agents are the following.
(1) 5% chlorothalonil dust is used to control downy mildew, anthracnose, early blight, late blight of various vegetables.
(2) 5% downy mildew dust is used to control downy mildew, rickets and cucumber blight of various vegetables, tomato late blight and so on.
(3) 6.5% of the moldy mildew dust is used to control gray mold, leaf mold and anthracnose of various vegetables.
(4) 10% anti-mildew dust is used to control cucumber downy mildew and tomato late blight.
(5) 12% gram of charcoal dust is used to control cucumber anthracnose and black star disease.
(6) 12% benefit dust is used to control gray mold, leaf mold, early blight and late blight of various vegetables.
(7) 10% B dust is used to control bacterial diseases such as bacterial bacterial leaf spot.
(8) 5% cockroach dust is used to control pests such as aphids and whitefly.
3. Dust application notes
(1) Pay attention to the choice of the dust of the counterpart. It must be understood that the dust preparation is different from the wettable powder. Dust preparation should use dust preparation, and WP cannot be used instead of dust. Use dust to be used, such as control of cucumber downy mildew, tomato late blight, use 10% anti-mildew or 5% chlorothalonil dust; control cucumber anthracnose, black heart disease, use 5% chlorothalonil or 12% gram Charcoal dust and so on.
(2) Pay attention to the selection of a suitable duster. It must be applied with a duster and cannot be replaced by other instruments. It is advisable to use a domestic harvesting type 5 or 10 hand-cranked duster. Before the application, close the greenhouse or the greenhouse, and then measure 1 kg per mu (1 mu = 667 square meters, the same below), put the pesticide into the sprayer medicine box, and adjust the powder volume to 200 grams per minute. about. The duster and dust must be kept dry and no wet or caking agents should be used.
(3) Pay attention to the spraying time. When the sunlight is strong in the morning to the afternoon, the dust spraying effect is low. Therefore, it is advisable to apply the medicine in the morning or evening on sunny days, and spray the medicine on cloudy and rainy days. Applying the best after closing the shed in the evening.
(4) Pay attention to the spraying method to spray directly on the vegetables, whether it is uniform or not, the effect is very poor. Only when the powder is evenly sprayed, the effect will be good. Do not spray again within 3 days after dusting, so as not to wash away the powder and reduce the efficacy. Generally, the medicine is sprayed before the onset or at the beginning of the disease, and then sprayed once every 7 to 10 days, and the medicine is continuously sprayed 2 to 3 times depending on the condition.
(5) Pay attention to the safety operation rules of pesticides when spraying safety operation. It is required to wear long-sleeved overalls, goggles, masks and protective caps. The hands and other exposed skin must be cleaned after work.

2. Working principle of led solar wall light
In addition to the components of traditional wall lights, solar led wall lights also have components that traditional wall lights do not have, such as solar panels, controllers, and batteries. Its specific working principle is as follows: during the day, when the sun shines on the solar cell, the solar panel will convert the thermal energy generated by the light radiation into electrical energy, and the battery will be charged and stored through the charge controller. When the night comes, the controller will control the discharge of the battery to meet the needs of night lighting.
3. Features of solar powered led wall light
1. The primary feature of the solar wall lamp is that it can be charged automatically. When the sun shines during the day, the solar wall lamp can use its own components to convert light energy into electricity and store the electricity, which is impossible for traditional wall lamps.
2. Solar wall lights are generally controlled by intelligent switches, and they are automatically turned on by light control. Usually it will automatically turn off during the day and automatically turn on at night.
3. Since the solar wall lamp is driven by solar energy, it does not need an external power supply or complicated wiring, and the work is very stable and reliable.
4. Ultra-long service life, the solar wall lamp uses semiconductor chips to emit light without filament. Under normal use, the lifespan can reach 50,000 hours, compared to 1,000 hours for incandescent lamps and 8,000 hours for energy-saving lamps. Solar wall lights can be said to be very long-lived.
5. We know that ordinary lamps and lanterns contain two elements, mercury and xenon. The used lamps and lanterns after use will cause great pollution to the environment. But the solar wall lamp is different. It does not contain the two elements of mercury and xenon, so the waste solar wall lamp will basically not cause environmental pollution.
6. Health. The light of the solar wall lamp does not contain ultraviolet rays and infrared rays, and this kind of light will not cause harm to the human eyes even if it is in contact for a long time.
