Nursery technology
Small greenhouse awning nets were used to cover nursery. The middle and lower reaches of the Yangtze River were planted on July 20-25, and planted from late August to early September. The seedling age was controlled at 28-35 days, and about 50 g per mu were used.
1. Seedbed selection: The seedbed should be high-lying and easy to drain, and the former has not been planted with plots of eggplant, melon and bean vegetables. According to the size of the seedbed planted, the seedbed can be generally 1.5m wide. 40-60cm long single or 20-30cm double, flat surface, digging a drainage ditch around the seedbed.
2. Preparation of nutritious soil: nutrient soil is best to use the mud in the next year or the field soil or garden soil not planted with vegetables, the sun through the sun, heap stuffy spare, the proportion of nutrition soil formula: 80-85% of the soil, 15- 20% of pigs, cows and poultry manure treated with high temperature, plus appropriate amount of plant ash and a little superphosphate, fully mix evenly, nutrition soil is well equipped, and can be installed, usually 10cm10cm or 8cmcm of plastic nutrients, The soil thickness is about 6-8cm, and then it is discharged into the seedbed.
3. Sowing: Before sowing, soak seeds for 1-2 days, use constant temperature hot water of 50-55°C, soak for 20-30 minutes or soak for 20-30 minutes with 10% sodium phosphate aqueous solution, and rinse with water. Seeds can be germinated and can be sowed directly. Generally, the seedlings cultivated in the fall season are suitable for direct seeding. Before sowing, the seedlings are soaked with nutrients. After the water is soaked, a small hole is tapped with the index finger, and 2 full seeds are put into each hole. The cover soil is about 0.8-1cm thick, and the surface is covered with agricultural non-woven fabric or thin straw curtain.
4. Set up a sunshade net: After sowing is completed, use a bamboo pole or arch rod to take a small arch shed on the seedbed. The height of the shed is 0.8-1.2m, and then use the shade net to cover the lower cover film. The gap around the lower part of the shed can not be covered by 15-20cm. Eli is airy and light-transmitting, sunny days do not cover the film, rainy days, cover the film, and remove the film after rain.
5.Management: This is the key point for the cultivation in late autumn. As the saying goes: "The seedlings are well received". In August, the temperature is higher. Seedlings can emerge 5-7 days after sowing. The surface covering (non-woven or thin straw curtain), the bed surface should always be kept moist at the seedling stage, if the lack of water can be used to fill the water with a fine hole watering can, to avoid drying, watering should be in the morning and evening In the rain, it is covered with rain and the film is removed after the rain. At the same time, to achieve and time seedlings, remove weak caps, captains and other weak seedlings to ensure that each seed has a strong seedling. For the prevention of viral diseases, virus A or phytophthora should be sprayed twice at the seedling stage. If the seedlings lack of fertilizer, 0.2% potassium dihydrogen phosphate and 0.2% urea can be added at the same time as the spraying (if the underground pests are found in the seedlings, they are killed by the bran mixed with saussurea). Before planting, lightly apply the fertilizer once, fight the insecticidal fungicide again, and pour enough water.

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.
