Summer and autumn pepper seedlings attention

The summer and autumn pepper seedlings are susceptible to high temperature, rain, drought and other weather, and the seedling pests and diseases are serious. In order to ensure the normal growth of seedlings, the following measures should be taken: First, to prevent high-temperature hazards Select well-ventilated plots for seedbeds, build shading sheds, cover with shade nets or non-woven fabrics, shade branches, or on plastic films Spray mud water. After sowing, the nursery bed is covered with rice straw and the seedling cover is immediately removed when 60%-70% of the seedlings are unearthed. Through shading, the temperature is lowered and the light transmittance is reduced, which is conducive to the growth of seedlings. Second, to prevent the danger of heavy storms Select lands with high groundwater drainage around, do seedbeds, and timely discharge of water in case of heavy rain. Shade cooling cover method is best to use "a net and a film" covering method, that is, covering the plastic net film shade net, its shade cooling, anti-rainstorm performance is better than a single shade net coverage effect, before the rainstorm Pull the plastic film down, place the air outlet tightly, surround it with soil, prevent rainwater from flowing into the seedbed, and fix the film line to prevent it from being blown away by the wind. If the seedbed enters the water, the soil will harden and the unfavorable seeds will germinate and become unearthed, which can easily cause a large number of dead seedlings. Third, to prevent drought hazards before sowing, to test the seed germination rate, according to the test results to determine the amount of seeding, seedlings planted in the seedbed after sowing or full irrigation, and then site preparation, sowing water can not use sewage, dirty water, preferably with groundwater . Before seeding, seedbeds should be moistened in shade. According to the weather conditions, a small amount of water can be sprayed on the seedbeds in the morning or evening with a watering can to prevent drought. 4. The main reasons for preventing seedlings from becoming seedlings are insufficient illumination, weak photosynthesis, low nutrient production, high temperature, especially high night temperatures, strong respiration, and consumption of nutrients, resulting in a reduction in dry matter content in the body, combined with nitrogen fertilizer and moisture. Adequate, promoted leggy. In addition, the density of seedlings is too large, blocking each other, lack of light, the seedbed is not ventilated, there is less light around the seedlings, only the top receives more light, prompting the rapid growth of young stems, causing leggy. Seedbed should not be flooded with water, only with a watering can spray water, the amount of watering can not be too large, keep the seedbed see dry see wet, and time seedlings and seedlings, as long as it does not rain, the film should be open, easy to ventilate light , Rainy days, remove the shade, leaving only plastic film to prevent rain, and strive for more scattered light. V. Prevention and control of pests and diseases The effects of high temperature, virus diseases, aphids, cabbage caterpillars and other pests are prone to occur. Fertilization should be applied with adequately decomposed organic fertilizer. The seedbed is treated with carbendazim or formaldehyde and other agents for disinfection. Seeds need to be soaked in warm soup or treated with pesticides to avoid soil-borne diseases. After sowing, poison baits and poisonous earthworms are sprinkled in and around the seedbed immediately. The above measures are taken to reduce the seedbed temperature and prevent the occurrence of virus diseases. The disease-resistant varieties are selected, the insect-proof nets are used to raise the seedlings, and a yellow and yellow seedling bed is set up. Orange trap board, trap and kill locusts, fight drugs in time, commonly used agents are: 75% chlorothalonil, 50% carbendazim, 70% mancozeb, 20% virus A, 1.5% Phytophthora seedling cream, 50% Fluor Double, Xinwansheng, 50% anti-influx, 50% phoxim emulsion, 80% trichlorfon and so on.

Installing Bullet Solar Camera
1. Understand how solar monitoring works
The solar Security Camera mainly relies on its attached solar panel to convert the solar light into electricity and charge the built-in battery for monitoring. The integrated inverter in the monitoring can also convert the DC power from the solar panel to AC power, so as to provide power when the sun comes out. It is stored in its rechargeable battery during the day, and its power can maintain the continuous work of solar monitoring at night.
2. What are the advantages of solar monitoring over ordinary monitoring
Unlike wired common monitoring, it does not need to run wires to connect it to the power supply. They connect to the home safety system via a Wi Fi connection rather than a data cable. As a result, they are true wireless security solutions that are easier to install. With wired cameras, you need to place them on the wall where the power cord runs, or close to the wall outlet. In contrast, you can install additional solar monitoring anywhere, even if there is no outlet nearby.
3. Which functions are necessary in solar monitoring
Camera resolution, field of view, solar panel wattage, night vision, motion activation, remote monitoring and smartphone alarm. The resolution of the camera determines the sharpness of the monitored safety picture. Look for models with High Definition (HD) cameras or better. The field of view describes the coverage of the camera. Security monitoring with a wider view is always better. Night vision and motion activation indicate whether the camera can see at night and start recording when it detects motion in the coverage area. The wattage of the solar panel paired with the security camera indicates how much power it can generate from sunlight. The battery panel with higher wattage can charge the attached battery faster and provide more power for monitoring. Smartphone alerts and remote monitoring are designed to help you monitor your home or office in the absence.
4. Whether the sun monitoring can continue to work in cloudy days
The answer is yes. The solar panels connected to the solar monitoring system generate less power in cloudy and rainy days, but the excess power stored in rechargeable batteries in sunny days can help them survive rainy and cloudy days.
