Soilless cultivation

Soilless cultivation refers to a cultivation method in which a nutrient solution is poured without using natural soil. In the production of vegetables, it has the advantages of high yield, early maturity, water saving, light disease, and the ability to produce pollution-free quality vegetables. According to experiments, the cost of the nutrient solution used to produce 1 kilogram of vegetables is only a few cents. Urban residents can use verdant, roofless vegetables on the roof. The method is simple and effective. The methods of soilless cultivation of several vegetables are introduced here, providing new ways for vegetable growers to grow vegetables. (1) The new technique of soilless cultivation of leeks uses deep 18--20 cm pots or wooden troughs, with a 1-2-1 cm depth of sand in Henan, to prevent colonization. Choose the root of leeks in open field for more than 2 years, cut the old roots and leaves to leave the shortened stalk roots and insert them into the pots. The 3-4-strain is a rake with a spacing of about 33 cm. After the new root grows, it will be poured with nutrient solution. Generally, it will be poured once every 1 day, poured with 1 nutrient solution, poured once every 1 to 2 days in spring, summer and autumn, and poured in 3 to 5 days in winter. Times, no rain and no rain in the afternoon. Ye Huang more poured, less black leaves pouring nutrient solution. Nutrition formula: 15 grams of urea, potassium dihydrogen phosphate 2,25 grams, 15 kilograms of water, can be poured 1,5 square meters. (2) The new technique of soilless cultivation of cucumber does not slow down seedlings, and the transfer of rods for fertile seedlings shortens the growth period of soilless cultivation, increases the number of cultivated pods, and increases the total yield. Put the sticks on the sticks after the shift, only one main vine and 1--2 side vines are left, and the rest are erased. At the top of the melon, it is topped with 5--6 leaves. Soilless cultivation of cucumber disease is light, can be continuous species. In the period of strong cucumber crops, it is possible to plant seedlings, and when Huang returns to a fruitful period, it can be eliminated. In addition to planting seedlings of cucumbers that have been previously bred, the cucumber seedlings that thrive and produce more results are always maintained in the sand basin, thereby doubling the yield and increasing the benefits. (3) New technology of soilless cultivation of watermelon Watermelon soilless cultivation can improve 15-20 days of maturity, high yield, good quality, and high economic efficiency. A porcelain pot or plastic bag with a diameter of 30 cm and a height of 45 cm is used. The lower part is filled with a 15 cm pebble block and the upper part is filled with 8 to 90% of clean sand. Sprouting the watermelon seeds sowed in the river sand, sowing 1 - 2 tablets per pot and finally leaving a strong seedling; or use a nutrition bag to raise the seedlings and then transplant them into the river sand to disregard the sowing seedlings and just grow leaves. Transplanting seedlings began to be fed with nutrient solution, and the amount of each plant was 200--500 g. The upper and lower plants were applied once. The amount of seedlings at the seedling stage could be smaller, and the amount at the later stage could be caused. When the temperature is high and the light is strong, it can be added once at noon. Only one main vine or one side vine and one to two melons can be preserved per plant. Keep 7--8 leaf topping in front of the melon. Other management is the same as general cultivation. Nutrition formula: 15 grams of urea, 5--10 grams of calcium nitrate, 3,5--4 grams of dihydrogen phosphate, potassium nitride 1,8 grams, ferric chloride 0,35--0,4 grams, Borax 5, 6 grams, manganese sulfate, copper sulfate, zinc sulfate 1,5 grams each, nutrient solution PH value of 5,5-6.

Laser Knee Massager combine Red light and laser light to reduce the knee pain, And it also has heat and massage function.

Laser Knee Massager Product Features:
1. large LCD display, the device working details can be see clearly.
2. 808 nm laser irradiation, quickly relieve knee pain.
3. Carbon fiber infrared heating, deep to repair damaged tissues.
4. Humanized design, 90 degree exterior shape, no need extra handheld during the treatment.

Function 1

• laser light

[Mechanism] through the wavelength of 808nm, single laser output of the maximum power of 5mW laser irradiation of the nasal cavity or acupuncture points to the blood into a large number of photons, photons absorbed by blood cells and converted into internal energy, activation of blood cells, improve its ability to deform Oxygen-carrying capacity, improve blood flow and viscosity, improve blood rheology parameters, play to eliminate inflammation, reduce blood viscosity and lipid levels.

• LED red light rejuvenation

The red light with wavelength of 625nm has the characteristics of high purity, strong light source and uniform energy density, and is effective in skin care and Health Care treatment. Red light can improve cell activity, promote cell metabolism, so that a large number of collagen secretion of collagen and fibrous tissue filling itself. Red light for a variety of skin, can promote blood circulation, so that collagen regeneration, so that the skin is more smooth, improve the skin c dry, hair loss, hair follicle damage alopecia are improved.

Function 2

 â€¢ Carbon fiber is far infrared

 â€¢ The sun is the source of life, in all the sun rays, far infrared rays can penetrate the skin and subcutaneous tissue, promote blood circulation, quickly absorbed by the living body, known as the "light of life"; carbon fiber heating wire power, , The carbon crystal molecules to do "Brownian movement", carbon molecules friction and collision between each other, resulting in a large number of wavelengths in the 6 ~ 14um of the far red line.
