High-efficiency Cultivation of Muskmelon in Early Spring

High-efficiency Cultivation of Muskmelon in Early Spring

Victoria Muskmelon is a hybrid of Australian Australian company. The melon is medium in size, golden yellow in the peel, green in the flesh, sweet and refreshing. Warm winter greenhouse cultivation in early spring, listed in early May, the market price of 4-5 yuan / kg, sales, 1/15 hectares of net income 5800-6700 yuan. Its cultivation techniques are:

First, the sowing date: winter warming greenhouse sowing time is generally from mid-December to late January, planting period from late January to early February. The arch sheds are planted in early March, and the nursery period is suitable from late January to early February.

Second, nursery preparation: a small arch greenhouse seedling nursery, seedbed length 5 meters, 1.2 meters wide. A power line with a power of 100-120 W/m2 can be laid at the bottom of the seedbed. Using nutritious lotus seedlings, the nutritious soil was prepared by mixing 6 parts of fertile topsoil with 4 parts of decomposed chicken manure, and then adding 1 kg of diammonium phosphate, 1 kg of potassium sulfate, and trichlorfon per cubic meter of nutrient soil. 60 grams, 80 grams of enemies, fully mixed, cap membrane stuffy for 10-15 days, can be loaded into plastic nursery pots, tightly on the seedbeds, watered to be broadcast.

Third, sowing: seed before sowing by 55 °C warm water soak for 10 minutes, and then warm water at 30 °C for 6 hours, wrapped with wet gauze, placed on 28-30 °C under conditions of germination for 3 days. 3-4 days before sowing, the temperature of the seedbed is increased to above 18°C ​​to sow seedlings. Each germinated seed is sown with 1 grain of germinated seeds, covered with 1-1.5 cm of soil, and the cover film is then warmed to maintain 28-32°C during the day. 17-20 °C at night. Appropriate cooling after emergence, 22-25 °C during the day, 15-17 °C at night. After the appearance of true leaves, the temperature is appropriately increased, during the day, 25-28°C, and at night, 17-18°C. When the greenhouse temperature exceeds 28 °C, timely ventilation.

Fourth, planting: advance buckling before planting, improve the temperature within the shed, the ground temperature is stable above 14 °C, seedlings grow to the four-leaf when the ventilation and hardening seedlings. 1/15 hectares of decomposed chicken manure 3000-3500 kg, 50 kg of diammonium phosphate, 30 kg of potassium sulfate, 3 kg of phoxim, applied after mixing fertilizer, and then diluted 70% of thiophanate 0.5 kg diluted 50 times , buried in the ground with the turning soil. Muskmelon hi light, suitable for ridge planting, large row spacing 90 cm, small row spacing 60 cm, ridge height 25 cm, seedlings planted on ridges, plant spacing 40 cm, 1/15 hectares planted around 1800 plants, digging and planting on ridges Seedlings, the depth of non-buried cotyledons for the degree, then pouring enough water. Immediately after planting, it was covered with a Plastic Film and buckled a small arch film to facilitate the increase of temperature.

V. Management after planting:
1. Temperature: Increase the temperature of the greenhouse and promote the growth of seedlings. Before the flowering, the temperature of the greenhouse shall be maintained at 25-30°C during the day, 16-18°C at night, and ventilation shall be provided when the temperature of the greenhouse reaches 32°C. After the fruit is set, the temperature in the greenhouse is 28-32°C during the day, not more than 35°C, and at 15-18°C during the night, maintaining a temperature difference of 10-15°C. At the same time require sufficient light to facilitate the accumulation of sugar and improve fruit quality.

2. Pruning, hanging vine, stay melon, hanging melon: Victorian melon can be used double vine pruning, the main vine grows to 4-5 leaves topping, promote hair 3-4 vines, retain two healthy cranberries, and the rest erase. When the retained double vines grow to 5-6 leaves, the vines are pulled on a plastic rope and the vines are wound on the ropes as the vines extend. Artificial pollination can be used. Select Sun Man sitting on the vine branch from 8-12. Sun vines have two leaves left after the female flower has been picked and the sun vines without female flowers are promptly removed. The cranberry leaves 20-22 leaves topping. 1 melon per child. When the young melon grows to about 500 grams, the melon should be hoisted in time, and the rope tied to the melon shank near the fruit part, and the melon should be lifted to the position where it is level with the seated melon, so as to prevent the melon from falling.

3. Fertilizer and water management: After the planting, the plant should be irrigated once, and 15-20 kg of urea should be applied during the extension period, and 15 kg of NPK fertilizer should be applied. Water should be applied after fertilization. Within one week after flowering, the water is controlled to prevent the upper stems from growing and affecting the sitting cucumbers. Swelling period is the period when the vines and young larvae require the largest amount of fertilizer. Apply 30 kg of potassium sulfate and add 250 kg of chicken manure. Sprinkle water every 7-10 days, depending on soil moisture. During the growth period, potassium dihydrogen phosphate compound fertilizer can be sprayed on the surface for 2-3 times to promote plant growth and development. Watering is strictly controlled 10 days before maturity to avoid cracking, lowering the sugar content, and affecting quality and flavor.

4. Diseases and pests control: 50% of anti-influx can be used 2000 times or Nonghaha 3000 times to control aphids and leaf miners. The use of 72% Kelu 1000 times or 500 times the metalaxyl manganese spray to prevent downy mildew, 70% thiophanate can be used 700 times or 77% can kill 500 times spray to control the disease, the stem on the lesions It can be applied by thiophanate 50 times into a paste. Powdery mildew can be controlled by 20% Triadimefon 1500 times.

5. Timely Harvest: It takes 35-45 days from flowering to fruit maturation, and it can be harvested when the skin is golden yellow. Shearing should be carried with fruit stalks to keep the fruit fresh and beautiful, packaged for Sinotrans or timely marketed.
