Cherry tomatoes cultivation
1. Variety The varieties currently on the market are mini, super-sweet, loving, 139 and so on. Their average fruit weight is about 15 grams, with 18-22 fruits per panicle. The fruit is small and round, and the dark red is the top grade. Resistant to transportation and storage, the market supply period can reach 4 months.
2. The temperature of cultivated soil in greenhouse is stable at 10°C and above is suitable for planting, while the temperature of cherry tomato in greenhouse is 78-80 days, which means that it is 70-80 days before the planting period. For seedlings under the seed period. The best way to raise seedlings is to raise live seedlings in a single seed. The nursery soil should be half of farm fertilizer and garden soil, plus one-thousandth of ammonium sulfate and potassium dihydrogen phosphate, sieving, and mixing. . Sowing to the emergence of soil temperature 25-30 degrees. The minimum temperature at night is not less than 10 degrees. Seedling watering to see dry see wet, can not be pouring water. Nursery sheds often ventilate and control the disease. Under normal circumstances, no fertilizer is applied at the seedling stage. When the seedlings were found to be thin and de-fertilized, 30 grams of urea and potassium dihydrogen phosphate could be sprayed on the leaves, and they could be mixed with 15 kg of water, sprayed once every 4-6 days, and normal growth could be resumed 3-4 times. To 7-8 leaves, see buds can be planted.
3, planting soil temperature stability at 10 degrees or more for the appropriate period of planting. 667 square meters of Shi fertilizer maturity 15 cubic meters, 7-10 kilograms of urea, superphosphate 70-80 kilograms, 40 kilograms of potassium sulfate, spread the ground and deep-turn 30 centimeters twice to reach the full layer of fertilization. For a width of 1-1.1 meters, 20-30 cm high ridge. The ridge roof is planted in double rows with a 40 cm spacing. Plant spacing 60-70 cm, about three plants per square meter planted. Planted foot water for 3-4 days before planting, and forbid any manure and manure after planting. Cover transparent plastic film. Covering the mulch from both sides of the ridge roof, it is better to cut the membrane in the seedlings.
4. Management After planting fruiting period, it is necessary to control the fertilizer and water. In addition to special droughts, it is generally not watered nor top-dressed. The temperature is controlled at 13-25 degrees. From the beginning of fruit enlargement period, the ground should always be kept moist. Each time the furrow irrigation should follow the water, 50mg of potassium dihydrogen phosphate per ridge. When the seedlings are thin, add 50 grams of urea once or twice. Each seedling has 2-3 lateral vines under the first flower head and 3-4 vine prunes. Lateral vines should be removed after the vines should be left undisturbed, so that cultivating roots is conducive to root growth. Should stay in top notch, timely framing vines. Winter greenhouse cultivation in the flower bloom period, can be used to set fruit Ling, tomato No. 2, 2.4-D and other anti-dropping spray flowers and fruits. Apply paper cover behind the ear during spraying to prevent the liquid from falling onto the vine and inhibiting growth. Harvesting begins 60-70 days after planting and can be harvested continuously for 4-6 months.
5. Pest control pests are mainly leafminers and whitefly. Leafminers can be controlled by predator sprays. Whitefly can be controlled with extermination and smoke agent No. 4. Diseases include gray mold, leaf mold, and viral diseases. Botrytis cinerea and leaf mold are mainly to strengthen the prevention and control of air-evacuation, temperature-control and moisture-removal, and promptly control the spraying of Accelerated Keling, Acetaminophen, Propylazem, Garrinone and Smokers No.1 and No.3. Viral disease must completely eradicate maggots and managers cannot work while smoking, controlling the source of infection. Seedlings, seedlings, seedlings, and so on, are all effective measures to control the occurrence of viral diseases.

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°,
