1, species selection. Select early-birds, Liaoxian No. 1, Teza 4 and Ningye 60.
2, sowing nursery. Before sowing, per kilogram of base chicken, 1,000 kilograms of chicken manure and 45% of three yuan compound fertilizer. To make a 1.2-meter-wide curtain, 0.2 meters high and 0.2 meters wide. In late February, the “cold tail warmer†was selected to sow fine crops and the amount of 5-6 kilograms per mu was used. Live sowing is better, point distance is 15-20 centimeters, spacing is 30-35 centimeters, sowing 8000-9000 holes per acre, 2-3 grains per acupoint and 1.8-220,000 acre per acre. After sowing, cover 2-3 cm thick fine soil, immediately after sowing, cover a layer of mulch on the entire sagger surface, and fasten the sash around the shed, increase moisture and promote seedling. After the seedlings cotyledon top soil, the sunny days were selected to scratch the mulch in a timely manner, and the seedlings were grown.
3, temperature control. Appropriate temperature in the shed before the emergence of 15-25 °C; Qimiao timely ventilation, keep 20-25 °C during the day to prevent high temperature and lengthy; after mid-March, the temperature is getting higher, should strengthen ventilation, in mid-April exposing the film of the greenhouse.
4, fertilizer and water management. Normal seedlings should not be fertilized, such as leaves affected by low temperature wrinkles, per acre with 50 grams of yellow leaf enemy fertilizer 50-45 kilograms of water, selected sunny afternoon spray. In the early stage of flowering, boron fertilizer and paclobutrazol are sprayed, and 45% of compound fertilizer is applied per acre to 20 kilograms. Fertilizer can be combined with cultivator to promote root growth. After sowing, seedlings should not be watered; excessive drought at seedling stage can be watered in an appropriate amount to promote hairy roots; water management during flowering and seeding period can grasp the principle of “dry flowers and dampnessâ€, and the water content at the initial stage of flowering should be less, and the humidity of the general assembly should fall out of flower. After watering, promote the growth of earthworms, but prevent the accumulation of water in the field.
5. Pest control. During the period of greenhouse seedlings, the low temperature and humidity in the shed period can easily lead to standing dead seedlings, and can be controlled by 200 grams of chlorothalonil smoke agent per acre. At the 4-leaf stage, soybeans were sprayed with chlorothalonil and carbendazim and sprayed once a week. In early spring, the occurrence of insect pests was lighter and occurred occasionally. The main insect pests were soybean meal, black maggot, and other low toxicity pesticides such as chlorpyrifos and chlorfluazuron. The use of methamidophos and other highly toxic pesticides was strictly prohibited. 7 days to prevent and control 1, even defense 2-3 times.
6, timely harvest. In mid-May, timely picking of soybean meal in batches, and morning market, in order to obtain higher economic benefits.

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.
