In order to prevent vegetable seedling diseases, some fungicides should be applied to the seedbed soil during nursery. However, many farmers do not know what medicine to use and how to use it. Now introduce four kinds of disinfection methods to vegetable farmers.
First, the seed bed soil disinfection method. This method is to add formaldehyde, methyl bromide, chlorinated bitter and other chemicals into the soil to seal and fumigate. The sterilization is relatively complete. In addition to killing the bacteria in the soil, it can kill the nematodes and grass in the soil, but it also kills. The beneficial microorganisms in the soil. Therefore, this method should only be used when soil pests and diseases are particularly severe.
Second, before sowing, cover the soil and Jin Lei Duomi mixed uniformly, the amount of soil per square meter seedbed plus Jin Lei Duomi 5 ~ 7 grams. Then 1/3 of the medicinal soil was spread on the seedbed and the remaining 2/3 of the medicinal soil was evenly covered on the seed. It has good control effect against common blight and damping-off diseases at the seedling stage.
3. For every 1000 kg of nutrient soil, use 40% formalin 250 g to 60 kg water, mix and stack, cover with plastic film for 24 hours, spread the film evenly on the seed bed after 10-15 days. Can sow.
4. Use 25% of Rhizoctonia 50 grams to 50 kilograms of water. Mix and mix 1000 kilograms of nutrient soil. Mix evenly on the edge of the spray. Accurately spread on the seedbed after 1 hour of accumulation.

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.
