Water chestnut gardens with water sources should be watered in time. For those relying on natural rainfall, the tree trays should be trimmed in time to ensure water for the later growth and nutrient accumulation of chestnut trees, laying a good foundation for next year's production.
Loosen the soil in time to cultivate the soil of the chestnut orchard, and bury the weeds shallowly within the projection range of the canopy, in order to loosen the soil and increase soil organic matter. Generally combined with basal fertilizer application, the depth is generally 20 to 30 cm. Attention should be paid to the depth of the canopy and the shallowness of the trunk during culturing. When turning the soil, purposely damage a small part of the root system in order to make new roots and enhance the absorption of fertilizer and water.
Pruning and shaping the number of parent branches on chestnut trees and their strength are important indicators that determine the yield of the coming year. The main purpose of pruning is to make the chestnut tree's inner and outer parts, upper and lower parts to be able to produce strong fruiting branches, make full use of space, try to increase the fruiting parts, prevent the branches outside the crown from being too dense and high, and to ensure that the inner chamber is ventilated. Light. All the slender branches and male flowering branches that are too dense should be thinned out, and a small part of the branches should be shortened to cultivate strong newer branches to lay the foundation for the next year. Following the principle of pruning should be early but not late, light and not heavy, cut off diseased branches, dead branches, overlapping branches, thin branches, and hanging branches. The cut branches should be taken out of the orchard and treated or burned separately.
Disease and pest control After picking fruits, attention should be paid to clear the garden in time, cut off dead branches and branches with serious diseases and insects, and remove the branches and leaves that fall off the ground, and burn them or bury them.

There is no doubt that solar monitoring has brought great convenience to people. It saves a lot of manpower and material resources without having to stick to the post for 24 hours as before. Not to mention that the current surveillance cameras have the function of motion detection. As long as someone enters a certain range, it will automatically alarm and capture the scene. What is the function of the solar monitoring system?
1. Solar panel: The solar panel is an important part of the mobile phone software of the solar power generation system, and also a part of the practical value of the mobile phone software of the solar power generation system. Its function is to convert the professional ability of radioactive substances in natural light into electric energy, or send them to storage batteries, or promote load work.
2. Solar controller: The solar controller is used to control the operation of mobile phone software in all systems, and has the functions of overcharge protection and overcharge maintenance for the battery. In areas with large temperature difference, the qualified controller shall also have the function of temperature compensation. In the mobile phone software of the solar road lamp system, there must be light control switch and time control solar road lamp operation.
3. Battery: generally valve controlled maintenance free lead-acid battery. In the mobile phone software of small and medium-sized systems, in cold weather areas, a solar gel battery needs to be configured, which can be used at low temperatures, with high efficiency and is not vulnerable to major damage. Its function is to store the electric energy of the solar panel when the sun shines, and then release it under certain conditions.
4. Variable frequency power supply: split wave type and sine wave type. In order to provide power for 220VAC electrical products, it is necessary to convert the DC stabilized voltage power supply in the solar power generation system software into AC circuit energy, so DC AC variable frequency power supply is required.
