In order to reduce the humidity in the shed, some vegetable farmers choose to cover the mulch in the operation line in order to achieve better dehumidification effect. However, after a long time of stepping on, it is easy to cause soil compaction. Covering some coverings with good air permeability and moisture absorption, the effect is much better than the covering film.
rice husk
After the operation covers the rice husk, it not only reduces evaporation but also exerts a certain moisture absorption effect. More importantly, after laying, the gas permeability is good, it will not lead to soil compaction, and the rice husk can be turned into the soil when the soil is turned over, which can improve the soil, increase the soil permeability, and improve the soil fertility after decomposition. It is a multi-purpose.
Smashing straw
Straw rot is slow, and it will become an obstacle when it is directly placed on the operation line. Therefore, it is recommended to smash the straw, because the surface area of ​​the moisture absorption after the straw is pulverized is increased, and the effect is good. Of course, laying the smashed straw not only absorbs moisture, but also directly prevents the evaporation of water in the soil. These crop straws can release heat and carbon dioxide during the decay process, and increase the temperature in the greenhouse and the photosynthesis of the vegetables.
Peat is also known as peat. Contains a large number of plant residues, humus and a part of minerals that are not completely decomposed. The peat is laid in the operation line, and its moisture absorption effect is better than that of rice husks and straws. It is a good organic fertilizer. It is understood that the price of peat is generally around two to three hundred yuan per square, and the price is easy to accept.
plant ash
Grass ash is a remnant of the burning of herbs and woody plants and is common in rural areas. Because the plant ash is rich in mineral elements, it is also a better fertilizer. The plant ash has good hygroscopicity and will play a certain auxiliary dehumidification effect in the shed; at the same time, the ash can prevent the mollusks such as cockroaches from biting the vegetables, and can provide nutrition for the vegetables after dissolution.

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.
