Qi Tian No. 1 melon greenhouse cultivation

Qi Tian melon, early maturity, 82 days of growth, strong resistance. Because of its good quality, sweet and crisp taste, and high sugar content, it is well received by the elderly and children. Early listing, high prices, and good economic value. The yield of greenhouses per mu is about 1,600 kg. The main cultivation techniques are summarized as follows:

First, the main features

Sprawl, strong growth potential, mainly cranberries. The melon is pear-shaped, measuring 12 centimeters long and 8 centimeters wide. The young rind is greenish and has a shallow groove. The ripe melons are yellow-white, the flesh is white-green, the melons are orange, the flesh is 1.9 centimeters thick, and the average fruit weight is 280 grams. More resistant to downy mildew, anthrax, and powdery mildew.

Second, the cultivation techniques

1, nursery seedlings in early March, planting in early April, seedling age 30-35 days.

Bed soil preparation: Fertile soil 40%, Chen Ma excrement (or peat soil) 40%, 10% of large surface, furnace ash slag 10%, plus 2 kg of diammonium phosphate per cubic meter of nutrient soil. The nutrition bowl or nutrition block is 10 cm in diameter and 8 cm in height.

Seed treatment: Use hot water at 55°C for 15-20 minutes and stir continuously. Wash and soak seeds, and wrap it with a damp cloth after 12 hours, and germinate at 28-30°C.

Sowing: When the shoots are 0.5 cm long, one seed is sowed in each nutrient pod and the soil is covered with 1 cm. A layer of plastic film can be placed on the seedbed.

Seedbed management: The temperature after sowing is 28°C during the day and 18°C ​​during the night. After emergence, remove the covered mulch. The daytime bed temperature is controlled at 25-28°C and 13-15°C at night. Generally, it is not watered during the seedling period, and it can be sprayed in small amounts when there is water shortage.

2. Planting and fertilizing: Before planting, 20 days, the fully decomposed organic fertilizer will be applied to 4,500 kg per acre (cake kg 80 kg, diammonium phosphate 30 kg, mixed and applied to the surface, deep ridged, ridged. 80-100 cm wide and 15 cm high.

Colonization: Two rows of ridge colonization, plant spacing 30-35 cm, planting about 2500 plants per acre, 7-10 days after planting heat preservation seedlings, when the temperature reaches 30 °C ventilation and ventilation.

3, field management of temperature and humidity management: After planting suitable growth temperature control at 20-30 °C, but with the outside temperature gradually increased, to increase ventilation, prolong the release time. The humidity in the booth is maintained at 50-60%.

4, top dressing and water management Topdressing: fruit expansion period, per acre phosphorus ammonia 20 kg, if the base fertilizer is insufficient, can spray potassium dihydrogen phosphate in the flowering period. Moisture management: sub-suspension, water before flowering, and water swelling. The water must not be too cold and the amount of water should be appropriate. Stop irrigation 10 days before fruit ripening.

5, pruning vines, greenhouses, melons with hanging cranium three-dimensional cultivation. Pruning is done before flowering. Generally use 3 or 4 vine pruning. When the main vine grows 4-5 leaves, hang the vines and use the vine pods on the main vines 8-10. Each cranberry retains 1 melon, and each 2-3 melons, each vine spreads in front of the melons. 3 leaves topping, the main vine grows to 20 leaves when the tip of the vine.

Third, pest control

Chemical pest control with biological pesticide pestochlor against acarids, aphids. Use phoxim to control underground pests such as tigers and earthworms.

Chemicals prevent seedling stage blight: spray with 5% 500-1000 times Jinggangmycin. Fusarium wilt: Spray with 300-700 times penicillin with 2% water. Bacterial Keratopathy: Streptococcus leaf spray.

Fourth, timely harvest

From July to September, when it is cooked, it will be listed on the market, with the best quality, and it will be harvested at 7 minutes when transported long distance.
