After the citrus harvest, the Qingyuan is right.
Scientific citrus post-harvest cleaning work in addition to cleaning the orchard, killing pests and diseases, but also need to pay attention to soil-cultivation, deep-turning and anti-freezing of the whole park, which should be carried out in a targeted manner according to the basic conditions of the local orchard.
Restoration of tree potential after harvesting
Generally, after harvesting, the orangery can not be trimmed immediately. According to the citrus variety, age, cultivation management, climatic conditions, pest occurrence, etc., the counters are selected and sprayed in appropriate weather to evenly spray and prevent shearing. Oral infection bacteria, combined with foliar fertilizer to quickly supplement nutrition and restore tree potential.
Plastic trimming clean orchard
After the first spray, the temperature is lowered until the spring buds, and the citrus trees are trimmed in winter.
Pruning: Cut off the branches and leaves of pests and diseases, and remove the diseased leaves, dead branches and residual fruits of scale insects, Mongolian cattle, ulcer disease and soot; remove the weeds around the net orchards and bring them out of the garden. Trim the wound in time to apply grease, seal the wound and protect the wound from healing.
Cleaning: comprehensively remove weeds and nearby parasitic plants, completely remove lichens, mosses, dead piles and rotten fruits; excavate yellow dragon disease plants, remove dead trees or trunks damaged by beetles, resin diseases, etc.; Butterfly moths and mediators.
Plastic surgery: using the big branch pruning technique, sawing the vertical branch, "opening the skylight" to reduce the height of the canopy; thinning the dense cross branches, pulling the erect branches with ropes to open the crown.
Spraying and spraying to kill pests and diseases
The ecological environment conditions in winter are not conducive to the survival of pests and diseases, the activities of pests and diseases are weak, and the distribution is relatively concentrated, which is convenient for prevention and treatment. At this time, the citrus tree is applied once again, which can completely kill the winter pests and diseases and ensure high yield in the coming year.

Mini Camera Introduce
1. Wired camera
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
