The key to high yield of early melon seedlings

Cultivation of melons in the early spring is a time-to-market and high-efficiency market. However, it is difficult to grasp the seedling raising technology, especially in rainy and snowy weather, it is very difficult to succeed in raising seedlings by conventional methods. Here is a brief introduction of the experience of some successful farmers to readers.
First, the fire seedlings nursery: In the greenhouse to dig 2 meters wide, 6 meters -7 meters long, about 20 cm deep seedbed, remove the soil and set aside the bottom and build back into the Long fire. In Shantou digging fire stoves, fire stove with brick chimneys, chimney height of 1.5 meters, fire stoves, chimneys outside the greenhouse, loaded with nutrients: 50 kg of chicken manure per plant, superphosphate 2 kg -3 kg, take The earth excavated in the fire pit is sieved with a sieve and mixed with fertilizer. It is put into a nutrition bowl with a height of 8 cm and a diameter of 10 cm. Appropriate varieties such as Elizabeth and Champion were planted in due course. Soak seed before nursery, in the coal furnace, with a small pot (or enamel cylinder) Shengshui, burn to 50 ° C, the seeds into the pot, stirring for 10 minutes. If the temperature exceeds 50°C, cool water may be added, and when the temperature is less than 50°C, the fireproof opening may be loosened. After 10 minutes, the pan was turned off and stirring was continued until the water temperature dropped to 20°C. Then soak for 3 hours, remove and place in a ventilated, warm place, maintain a certain temperature for germination. Seeding begins when 80% of the seeds are white. Usually sowing in early December, sowing 2 - 3 seeds per pot, then cover 0.5 cm -1 cm of fine soil. The ground temperature is maintained at 15°C-22°C, and the seedlings can be produced within 3 days to 5 days.
Second, the seedbed management: After the seedlings are out, one must prevent "high-legged seedlings" and the other must prevent "miseous disease". Control measures: (1) The temperature in the shed must be controlled at 25°C-30°C during the day and 15°C-18°C at night. To prevent and control "miseous disease", 800 mg -1000 times of hymexazol was used to infuse 800-1000 times of high-activity active liquid fertilizer into the seedbed.
Third, transplanting and planting: First apply the base fertilizer, leveling and thinning, when the seedlings grow 3 - 4 true leaves, the ground temperature can reach above 13 °C can be planted when planting spacing 120 cm, 30 cm spacing, every 667 Planting 1800 plants - 2000 plants. After colonization, spraying chlorothalonil plus all-natural spring plant growth agents every 7 days to 10 days until the picking of the melons. Watering 3 times throughout the growing season. After the first water is slowly growing, the second water is sitting on the melon, and the third water is ripe at the melon 8. After harvesting the head crop, 25 kg of urea and 25 kg of compound fertilizer were topdressed and then watered.
Fourth, strict management: In order to increase the fruit setting rate, it is necessary to conduct artificial pollination, or to sit with flowers and flowers. Hanging vine pruning, when the main ranch grows 6 - 7 leaves when hanging vines. Destroy all the vines in the 5th section so that they sit on the side vines that grow on the 8th -10th section. When the main stem grows 20 leaves, it picks up its heart, and when the vine grows, it takes 2 to 3 leaves to pick it up. Temperature control after planting: keep at 27°C-30°C during daytime, not lower than 20°C during night, reduce ventilation after easing seedlings, keep at 20°C-30°C during flowering, not lower than 15°C during night, maintain at flowering daytime 28°C-30°C, not lower than 15°C at night.
