Choose high-quality, disease-resistant, high-yield, wide-adaptability, good commercial, and suitable for market demand.
Second, nursery
Use high quality seedlings produced in the nursery of this base.
Third, the sowing period
Greenhouses, greenhouses and open field cultivation were planted in August-September, mid-December and mid-March, respectively.
Fourth, colonization
1. Fertilize 6,000 kg of chicken manure per acre, 30 kg of diammonium phosphate, 15 kg of urea and 20 kg of potassium sulfate compound fertilizer. After fertilization, fully plowing, the depth of cultivated land is 20-30 cm. Then make a fuss and smooth your face. Cover film compaction.
2, when the time of planting melon seedlings up to 4 leaves 1 heart, choose sunny. Greenhouses, greenhouses and open field cultivation were planted in September-October, January and April respectively.
3, colonization method spacing 80 cm, spacing 30 cm, size and size of seedlings planted.
4, the temperature in winter to prevent frost insulation, keep the shed within the daytime 25-28 °C, no less than 12 °C at night.
5, Feishui potassium sulfate compound fertilizer 15-20 kg and urea 15-20 kg alternating topdressing, point application. When the winter is cold, 20-40 kg of diammonium phosphate should be topdressed. When necessary, supplemented with foliar fertilizer. On the basis of pouring enough water for colonization, generally do not water before sitting in the melon, watering after sitting on the melon, and keep the stem dry and wet alternately.
6, hanging loofah planting slow seedlings, began to hang.
7, when the entire vine spread when the vines, in time around the vine. When the melon spreads to the top of the rack and begins to fall, the leaves of the lower part of the main vine below 50 cm are completely removed, and the melon vines are coiled and reattached.
8, pruning generally leave the main vine melon. Before sitting on the melon, remove the branches on both sides of the main vine. If the main vines sit less, you can leave the seeds vines; after vines, leave 1-2 leaves topping.
9. Pollination and flowering At 7-9 am on the same day, flowering or artificial pollination is performed.
10. During the growing process of fruiting melons, the old leaves, diseased leaves and tendrils should be removed in time, and the root melons of the diseased melon, insect melons, malformed melons and the lower part of the main vine below 50 cm should be promptly removed. For curved melons, use small bricks or clods for hanging weights, tie them to the top of the melon with a string and hang straight.
V. Pest Control
1. The selection and use of pesticides strictly control the application amount and safety interval. Loofahs rarely suffer from diseases and insect pests, but they are prone to downy mildew, epidemics, etc. under conditions of prolonged rain, humidity, lack of light, and poor ventilation. At this time, the condition must be controlled at the initial stage.
2. Downy mildew mainly damages the leaves and can be sprayed with 72% Kelu WP 133-180g/mu, 250g/l Amisida (azoxystrobin) Suspension 32ml/mu, or 70% Antai Health (Prosenzin Zinc) WP 150 g/Mu, 40% Dakkon (chlorothalonil) Suspension 120-140 ml/Mu, 52.5% Fast-acting (?-keto-urea cyanogen) WP 23 g/mu. Spray once every 5-7 days after onset
3. In the onset stage of the epidemic disease chamber, use 40% Dakkonin (chlorothalonil) suspension 120-140 ml/mu, or 60% pybutromycin (Pyraclostrobin-Sensin) water dispersible granules. 60 grams / mu spray control. Spray once every 5-7 days after onset.
4, powdery mildew 1 to enhance ventilation, watering or cloudy days pay attention to air release. 2 At the beginning of the disease, spraying 40% dakoon (chlorothalonil) suspension 120-140 ml/mu, 400 g/liter Fuxing (fluorosilazole) EC 7.5 ml/mu, 430 g/l tebuconazole suspension 15 ml / Acres, 25% pyraclostrobin EC 20ml/mu. Spray once every 5-7 days after onset.
5. Bacterial diseases 1 Use disease-free seeds. 2 Seeds were soaked in warm water at 45°C for 10 minutes and sowed after disinfection. 3 At the beginning of the onset of spraying, 500 times of the WP can be killed, or 3% of the WP can be 80 g/mu. Spray once every 5-7 days after onset.
6, aphids, whitefly 1 with yellow traps to kill adult, and hang in the seal pest network; 2 cultivate insect-free seedlings; 370% imidacloprid WP 1000 times, 20% acetamiprid soluble powder 10 g/mu, 2000iu/ Ml. Bacillus thuringiensis suspension 20-30 ml/barrel. Spray once every 5-7 days.
6. Harvesting
Cut or break along the middle of the fruit handle, gently neatly discharged into the package.
