One is autumn farming. After the tea trees have taken spring, summer and autumn tea, they fully absorb the nutrients in the ground, and the soil becomes more compact. If fertilized at this time, it is not conducive to tea tree absorption. Therefore, tea gardens in the closure of the park, after stopping the tea, should be a shallow cultivation, loose soil, change the soil structure, promote fertilizer decomposition and tea tree root growth, lay the foundation for the next spring tea. The autumn tillage time is from October to November, when the root system is destroyed, it is easy to recover; the autumn tillage depth is about 1 foot, and the thin soil layer can be deeper, and vice versa.
The second is pruning. For the production of tea plantations, mechanical trimming is recommended.
The third is base fertilizer. In combination with applying organic manure in autumn ploughing, 300-500 pounds of oil per acre or 1000-2,000 pounds of livestock manure is used. At the same time, the weeds in the tea garden are buried in the soil.
The fourth is the Qingyuan Garden. Combine deep plowing and pruning to make the clear garden work. The weeds and litters between tea trees are the hidden places of pests and germs. Clearing the garden will help reduce the number of overwintering pests in tea gardens. The specific method is "Sanguang", which means picking up insects, eggs, and worm pods on the light tea tree; removing dead leaves from the light diseased leaves; lichen lichen on stripped light sticks to reduce the base number of overwintering pests in the tea plantation.
The fifth is to lay the grass. Use fireweed, straw, etc. to cover the rows and roots of tea trees to help increase soil temperature and maintain soil moisture. It can also use straw, weeds, or films to cover the cover. After the spring, the cover must be peeled off in a timely manner in order to achieve anti-freeze, promote early germination of the tea tree, and develop strong shoots, thus achieving high quality and high yield of spring tea.
The sixth is to seal the garden medicine. The overwintering pests of tea plants mainly include leaf blight, round spot disease, small green leaf mites, cockroaches, cockroaches, etc. It is recommended to use lime sulfur for prevention and control. When spraying, the top and bottom, inside and outside of the tea plexus, the front and back of the leaves, the branches in the punting, and the weeds on the ground must be sprayed to improve the control effect. The closure of the garden should be completed before the end of November.

The main features:
1)Ideal cold light effects
Using the new LED cold light source, ensure energy saving and environmental protection and long service life up to 80,000hours and more.
The temperature increase of surgeon`s head below 1℃. LED do not engender infrared ray and ultraviolet radiation, without the temperature
rise and tissue damage caused by halogen shadowless light, also it can accelerate the wound healing after surgery, and without Radiation pollution.
With color temperature constant and soft, LED is very close to the sunshine.
1) Excellent shadowless effect
Lamp with the most scientific radian and Multi point light source design, ensure better uniform illuminance. When the lamps are partially occluded,
also can achieve perfect shadowless effect.Lamp panel radius of gyration ≥182cm, the lamp can be pulled to vertical floor, convenient to any angle illumination.
2) Excellent deep lighting
It is based on modularize method by Computer Aided Design, focused to irradiating with more beams of LED. It produces the deep lighting which beams
more than 1200cm,the illumination of center up to 180,000Lux or more, and offer the color temperature that can be adjusted from 3700K to 5000K which
is close to sunshine. Absolutely, it really reflects the color of human tissue and satisfied by all kinds of operating light needs.
3) Advanced control system
The use of liquid crystal display button control, to meet the needs of the medical staff of different patients with the brightness of the operation.
It offers illuminance memory function.
It does not effect using when a single circuit or one bulb is broken.
4) Universal suspension system
Rotating arm, a new type of alloy material is made of eight edge type.
Balanced system using imported arm module, more than 5 group universal joints, every cantilever must has more than 3 joints which can be rotated in 360°,
The structure is light, easy to manipulate, accurate positioning, can provide the maximum range of regulation.The equipped with fatigue correcting unit and
fix position hand handle device, easy to fix position after long time use.
5) Modern laminar lamp
The thickest part of lamp-chimney is not more than 10cm.
The lamp-chimney is made of ABS, The handle on the central of lamp can be detachable, can take high temperature (≤ 134°C) sterilization treatment,
easily adjust, flexible fixed.
