Rigging colonization when the seedlings 3 leaves 1 heart, seedling age 25 to 30 days can be planted. 3 to 4 days before planting, appropriate watering should be performed according to soil moisture. When the soil surface is slightly dry, the ridges will be ridged. The ridge width is 80 cm and the ridge height is 15-20 cm. During the planting period, part of the grass curtains were covered with shade, and the plants were planted in wide and narrow rows, with one ridge and two rows, 80 cm in small rows, and 100 cm in large rows. The ridges were finely leveled, and dark ridges were opened on the ridges. The dark grooves were 10 cm deep. 15 cm wide. According to the planting distance of 50 centimeters, the planting hole is planted, 250 to 500 milliliters of seedling water is poured per hole, and then the seedlings are taken from the nutrient bowl (maintaining the nutrient soil is intact) and planted in the hole, and the seedlings are protected at 1600 to 2000 plants/mu. Management of pre-planting management. Immediately after planting, pour a large amount of water and pour enough water to make it take root quickly. After the water infiltration, the soil should be slashed immediately to improve the soil permeability, and the cultivator should be deep cultivated away from the seedlings. The multiple cultivators can control the seedlings to grow long and the flower buds can differentiate and enrich. In combination with cultivators, the ridges are refurbished and fully covered with a 2 m wide, 0.006 mm thick mulch. Hanging vines: When the plants have 8 leaves, they are hung and tied. When the pruning grows weak, it is first to hang the vine, and the strong growth is slow and then hangs the vine for 1 to 3 days, so that the plant height is the same and the shade is not blocked. When hanging vines and vines, the lateral buds formed on the main vine are promptly removed. Fall vines: When the melon vines are high, with the harvest of the lower fruits to be promptly vines, the plants and leaves are evenly distributed. When falling, remove the old leaves, yellow leaves and pests. When removing the old yellow leaves, the wound should be kept away from the main vine to prevent the pathogen from infecting the wound. Fertilizer management: Before covering the membrane and harvesting the root melons, it is generally not necessary to top-dress with water. This stage lacks fertilizer, which can be sprayed with foliar fertilizer. After the first melon is harvested, the first water can be poured. Do not allow the water to flow onto the mulch. Follow the water to top up a small amount of fertilizer, mainly nitrogen, phosphorus, and potassium fertilizers, each time about 30 kg. Bio-fertilizer can be applied in a more appropriate manner. The second watering is generally carried out about 15 days after the first watering. Since continuous harvesting consumes large amounts of nutrients, the amount of topdressing should be increased during this watering. 30 kilograms. In the deep winter season, the number of waterings should be reduced so that no drought or water is poured. In the early spring season, it is poured every 5 to 7 days. Each time watering is added to the ternary compound fertilizer. After entering the month of May, the amount of watering increased again, which can play a cooling role. In addition, foliar fertilizer can be sprayed on each spray. Strengthening the immune system refers to enhancing the immune system of the human body. Immunity is the body's own defense mechanism, which is the body's recognition and exclusion of virus and bacterial invasion, the aging, damage, death, and degeneration of its own cells, as well as the identification of its own cells and the treatment of mutant cells and virus-infected cells in the body. Our company is able to produce pharmaceutical raw materials for strengthening immunity, mainly including:Levofloxacin Hydrochloride,Minoxidil,Meloxicam,Clindamycin hydrochloride,Nebivolol,Amikacin,paracetamol,Gabapentin,Norfloxacin hydrochloride,Neomycin sulfate,streptomycin sulfate,Erythromycin,Baclofen,Dexamethasone,Duloxetine hcl,Ibuprofen,Bupropion HCl, baclofen,Rivaroxaban.

Greenhouse Zucchini cultivation essentials
Select seedlings generally choose disease resistance, low temperature resistance, high yield and high quality varieties. Use 300-400 grams per acre. Treated seeds are used to construct nursery seedlings in a solar greenhouse. Seedling temperatures before seedling exhumation are maintained at 28°C to 30°C during the day and 16°C to 20°C at night. When 70% of the seedlings begin to unearth, they must remove the mulch in time, strengthen the ventilation, reduce the temperature of the shed, and prevent the seedlings from growing in length. The shelf temperature should be controlled at about 25°C during this period. When the two cotyledons leave the ground to continue to increase ventilation and even remove the entire film, the shelf temperature is appropriate to about 20 °C, when the first true leaves flattened, the hypocotyl height has been basically set, this period can increase the temperature, See more sunlight, promote rapid growth of seedlings.
