Winter melon is not only thick and juicy, but also fragrant and refreshing. It also has the effect of clearing the heat, so it is loved by consumers.
A. Winter melon basin sowing shed
Winter melon time should be chosen around February 10, in early May can be harvested. Small shed and open field sowing time can be based on the ground planting habits. Plant 1700-2000 plants per mu with 150-200 grams of seeds. Yield of 5000 kg, production value of about 4000.
B. Winter melon soil selection
Winter melon on the soil requirements are not high, but winter melon is most afraid of continuous crop, as planted melon and more diseased vegetable fields are not suitable for planting winter melon.
C. winter melon seedling management soaking seeds
①Soak the seeds first with
Soak the seeds in hot water at 55 degrees Celsius for 3 minutes, and keep stirring the seeds in the hot water.
Soak in water for 15 hours, changing the water every 7-8 hours. Change the water and scrub with your hands to wash the surface mucus away.
③Strain up well with gauze
Put in hot water at 40 degrees Celsius and wash again, shake the water hard and gently bite through the shell of the pointed end first. Add a small amount of clean river sand to the seeds, and tie them up again with a food bag outside.
D. Winter melon electric blanket germination.
Start with a cardboard box and place the pint-sized bag with seeds in the box (no more than 150 grams of seeds per bag). Put the carton on the bed during the day, turn on the electric blanket to low temperature, and cover with a quilt. At night when there are people can not turn on the electricity, every 10 hours to check the dryness and humidity, generally after 2 to 3 days can be sprouted.
E. Winter melon electric hot line seedlings
First, make the seedbed ground finely, 1.1 meters wide and 17 meters long surface. Water the bottom water thoroughly (the wet soil layer is around 4 cm), then smoothen with sand while splashing with 800 times solution of carbendazim and octosulfuric acid.
(1) After smoothing
Use nylon rope to pop into 8 cm wide line, and then use a knife to cut into 8 cm X 8 cm square.
(2) An electric wire
Lay the wire at a spacing of 8 cm along the compartment surface and press it gently in the seedbed. Depth of 1-2 cm can be, electric wire in the seedbed generally around 6 times, the remaining can be hung on the small shed bamboo piece.
(3) Square grid
Pick a 1 cm deep nest in the middle put a well sprouted seed and cover it with a small handful of moist fine soil. After making a compartment, lay a layer of mulch flat on top, cover the shed and connect it to the power supply.
(4) Winter melon seedlings
When 70% of them are out of the ground, you can cut off the power and remove the mulch.
(5) The weather is particularly cold
The outside temperature is below 2 degrees Celsius, and the inside of the shed is below 5 degrees Celsius. Electricity can also be properly supplemented for a few hours at night.
(6) Winter squash sown after April 1
Directly sow dry seeds by scattering the seeds on a watered seedbed, covering with soil, laying the ground cover and covering the shed.
F. Winter melon disinfection
Fields with more diseases in the previous period can be sprinkled with 3g-5g of diclofenac at 1 square meter. Or sprinkle with 100 kg of quicklime per mu, tilling and mixing can be done. The field with more insect pests can be scattered with 1 kg of phoxim mixed into toxic soil, and then tilled and mixed. Fertilizer application of a one-time application of a full base fertilizer.
①Mature human and animal manure
3000 kg, 40 kg of phosphorus fertilizer, 20 kg of potassium fertilizer, 10 kg of urea.
②Retrotted farmyard manure
1000 kg, 100 kg of rotted oilcane, 30 kg of phosphorus fertilizer, 10 kg of urea and 10 kg of potassium fertilizer.
③Retrotted chicken and duck manure
3000 kg, urea 10 kg, potassium fertilizer 20 kg.
④ Transplanting of winter melon seedlings raised in the greenhouse
Generally, they can be transplanted after 25 days (one leaf and one heart or two leaves and one heart).
⑤ Before transplanting winter melon
First, make a good nest on a well-made compartment (1.5 m open compartment, wrapped in a ditch) with two rows per compartment. The distance between nests is 50 cm, and the center of the nest is 20 cm from the edge.
⑥When transplanting winter squash
Do not scatter the square soil, the square topsoil parallel to the compartment surface, do not plant too deep and too shallow.
⑦ After planting winter melon
watering enough root water, the amount of watering according to the soil dryness and humidity. Then cover the mulch and draw out the seedlings.
⑧ Winter melon in the introduction of seedlings
You can open the opening of the mulch a little bigger, so as not to damage the seedlings. Use a small amount of fine soil to press the opening, and after planting, you can pour a small amount of water on the mulch and cover the shed.
G. Winter melon temperature management
Hang thermometers inside both the greenhouse and the shed. The thermometer should be hung in the center of the greenhouse, 30 cm from the top growing point of the crop. Pre-shed can be inserted upside down on the soil.
1. Temperature inside the winter melon shed
Above 35 degrees Celsius can be ventilated (when the sun is high, the vent can be opened wider, and vice versa is small), the afternoon temperature below 25 degrees Celsius can be closed.
2. Winter melon moisture management
Observe the growth of melon seedlings, if the moisture is not enough. Seedlings do not grow fast, the color is dead black not green, we need to make up water.
3. See if there is water on the mulch
If the soil is wet or not, pour some water on the mulch or uncover the mulch and water it according to the specific situation.
4. After transplanting winter melon on the frame
If the temperature is normal, after 25-30 days, you can set up the frame (seedling height is about 50 cm). Generally build a herringbone frame, with 1.5 m-2 m shelves, 1.5 m-1.8 m away from a group. 5. l.5 m high about bundled on the horizontal bar50 cm high from the ground in each side of a bundle of horizontal bars, and then bundle the seedlings in the following horizontal bars.
H. Winter melon pollination by immersion
When female flowers appear on winter squash, cut off the lateral branches below. The female flowers between 8-15 leaves seated melon is better, in the fixed melon to 8-15 leaves of flowers selected two for hand-pollination.
1. Winter melon in the morning
Pick a male flower in full bloom, remove the petals, and dip the heart of the flower against the heart of the female flower. Or use 5mls of seated melon spirit to 1kg of water with a micro sprayer and spray the melon fetus once.
2. Fixed fruit whole branch
When the melon grows to egg size, we should set the fruit, leaving a fruit shape between 8-15 leaves, good growth of the melon.
3. Winter melon on top of the melon
Leave 10 leaves to pick the tip, and cut off all the leaves of the side branches above the melon.
4. Young melon
There are about 1 pound to hang melon, the melon can be hung on both sides of the crossbar, all hanging on the crossbar.
5. Winter melon fertilization after hanging melon
Fertilize once, dig a small pit in the middle of the compartment every 4 nests. Mix 1000 kg of animal and human manure water (organic fertilizer), 10 kg of urea and 2000 kg of water in 667 square meters and pour it in the dug pit (if you have automatic irrigation equipment, you can use more efficient and fast water soluble fertilizer).
6. Soil is dry
You can also irrigate a shallow water for furrow irrigation, not diffuse irrigation.
7. Before irrigation
Reinforce the melon frame to prevent the frame from collapsing after irrigation. Harvesting winter melon early spring cultivation mainly highlight an early, so winter melon – grow up on harvesting (generally 20 days after fruiting), can not wait until the melon is old and then pick.
