High-yield cultivation of green honeynet melon in greenhouse

Cuimi is a netted melon variety introduced from Taiwan's Nongyou Company. It has beautiful color, sweet taste and strong fragrance. The use of solar greenhouses to suspend wintering cultivation will generally yield 3000-5000 kg of melon per acre, with clear economic benefits.

First, cultivate strong seedlings. In early December, a sunny nutrient bowl was selected for seedlings, and the seeds were sown after the seeds were germinated and exposed. During the seedling stage, the shed temperature is maintained at 25-30 ° C during the day and 15-18 ° C at night. Spray the chlorothalonil solution once after the seedlings are planted and before planting, and spray the potassium dihydrogen phosphate solution 2-3 times when the seedlings are strong.

Second, timely colonization. One week before planting, separate preparation and basal fertilizer, apply 5000 kg of rotten inorganic fertilizer, 250 kg of rotten chicken manure or cake fertilizer, 100 kg of superphosphate, and 30 kg of potassium sulfate per acre. Rake flat after deep turning, ridge according to size, large line spacing of 90 cm, small line spacing of 60 cm, ridge height of 25-30 cm. Seedlings with 3 leaves and 1 heart stage and seedling age of 35-40 are planted in the clear and sunny afternoon, 1 row per ridge, 35-40 cm plant spacing, 2200-2500 plants per acre. After planting, cover with plastic film and cover with grasshopper.

Third, field management. Do not ventilate for 3 days after planting. After slow seedlings, the shed temperature was maintained at 27-33 ° C during the day and 13-18 ° C at night. When the shed temperature is lower than 10 ℃ at night, a layer of rain-proof film is covered on the grasshopper, and it should be heated at night when it is cold. On a clear day at midnight, the shed temperature starts to reach 28 ° C, and the ventilation time depends on the temperature in the shed. On a cloudy day, the air is properly released without reducing the shed temperature. After planting, the seedlings are watered once, and when the size of the melons and eggs is watered once. Separate watering and fertilization, each application of 25 kg of diammonium phosphate or ternary compound fertilizer. Foliar fertilizer needs to be sprayed multiple times during the melon swelling period. Melon reticulate formation period severely controls watering and atmospheric humidity.

Fourth, plant adjustment. When the vine is 30-40 cm long, it is hanging, and when the main vine has 26 leaves, it is topping topping. Distinguish the melon positions reserved in sections 10-13 and 18-20, select two melons in the melon-retaining positions, and remove the lateral vines at other nodes. At flowering period, 7 to 10 pm every day, the flower will be used for sitting. When a single melon weighs 250-300 grams, hang the melon handle from a wire with a rope and put on a net bag.

Fifth, prevention and treatment of diseases. Secondary diseases of overwintering cultivation of netted melon are luxuriant and downy mildew. Alternately irrigate the roots with methyl tobzine and methyl benzylphosphine to prevent luxuriant diseases, and spray toxins such as toxins, mancozeb, and plexic to prevent downy mildew.
