Shallow ploughing and loosening soil should focus on tea gardening soil management and create good soil conditions for tea garden production. Affected by factors such as the amount of water needed for winter, there are many problems in the soil moisture of tea gardens. At this stage, a shallow ploughing of loose soil can be carried out on tea gardens. Shallow ploughing and loosening soil can make the soil temperature rise faster, which is conducive to the early germination of spring tea. At the same time, it can also remove weeds in tea gardens, reduce the source of pests and diseases, and ensure the ecological environment of tea gardens is good.
Tea spring shears are pruned by the drought and frost damage tea gardens, lightly trimmed for picking tea gardens, and trimmed for young tea gardens. The low mountains should be carried out in advance, the mountains should be thawed, and the temperature should be stabilized above 15 °C. It is advisable to finish the pruning before the spring tea sprouts.

How to choose a solar Camera?
1. Select a low-power controller. The controller will work 24 hours a day. If its power consumption is large, it will consume part of the power. A good choice is a controller that consumes less than 1 mA.
2. Select a controller with high charging efficiency. The controller of the MCT charging mode can automatically track the high current of the panel. Especially in winter or periods of insufficient light, the efficiency of MCT charging mode is about 20% higher than other charging modes.
3. Select the controller for bidirectional power regulation. Controllers with power regulation have been widely promoted. When there are few pedestrians at night, one-way or two-way lighting can be automatically turned off to save electricity. It can also adjust the power of the LED lights.
In addition to the above power-saving functions, attention should also be paid to the protection functions of the controller for components such as batteries. In addition, when setting the under-voltage protection value of the controller, try to adjust the under-voltage protection value to ≥ to prevent the battery from over-discharging.
