Fruit tree gum disease mainly occurs on fruit trees with weak trees and large trees. The disease is mainly caused by pests and diseases, improper fertilization, poor drainage, excessive pruning in summer, freezing injury in winter, sunburn, and excessive results. The prevention and control of the disease is: increasing organic fertilizer, reasonable application of nitrogen, phosphorus, potassium and trace elements, enhance tree vigor, and increase resistance to disease.
Minimize wounds during pruning, apply 5 bumeite lime sulfur to large wounds, collect dead branches and burn, prevent pupal pests, and reduce sources and wounds.
Scratch treatment spots. The lesions are limited to the surface and should be promptly removed after the spring. At the same time, apply 402 anti-disease 50 times solution or 50 mg Formamide arsenic in the wound, and then apply Bordeaux slurry protection; or directly apply 5 Baume degree of lime sulfur agent for prevention and treatment, and the effect is remarkable.
Before serious orchard germination, spray 40% methine WP 100 times. The growth period is combined with other disease prevention and spraying protection on branches.
The advantages are that the technology is mature, the industrial Network Camera technology is directly transplanted, the signal interference is not feared, and it is stable and reliable;
The disadvantage is that the installation is complex and requires wiring. It can only be accessed through a computer. The scope of use is limited and it is not suitable for home use.
2. Wireless camera
The advantages are that there is no need for wiring, the installation and increase of cameras are relatively convenient, and the cost of Internet access is low;
The disadvantage is that it will be interfered by the signal, which may affect the definition and transmission speed of the picture.
Extended data
Now the technology of solar energy monitoring is mature, and solar energy can be used to solve the problem of power supply. Outdoor monitoring can also choose more advanced solar energy monitoring. Remote monitoring without power and network is no longer an imagination.
1. Simple installation: install by yourself without inviting construction personnel;
2. Adjustable angle: 360 degree rotation, no dead angle monitoring;
3. No electricity connection: solar power generation and built-in lithium battery power supply;
4. No wiring: no wall chiseling or decoration damage.
matters needing attention
The configuration of the solar power supply system requires the customer to provide the total power consumption of each load equipment,
It is necessary to know the local lighting conditions and the duration of continuous operation of the equipment
Spring fruit tree flow gum disease
Defoliation of fruit trees mainly damages the trunk and main branches of peach, plum, apricot and other fruit trees. Swelling at the site of the disease, after the brown part of the wood becomes brown, a clear gel is secreted from the lenticels or the wound. It gradually turns yellow-brown to brown in contact with the air. It becomes a black lump over time and the bark at the site of the disease is rough and turtles. Cracked, difficult to heal, when the disease is severe, the tree vigor is weakened, and even the whole plant dies.
