How to grow winter melon? How to grow winter melon

Cultivation of winter melon.

1. Cultivation season: winter melon likes high temperature and has strong heat resistance, the higher the temperature in the appropriate temperature range, the faster the growth and development, so it is necessary to arrange its growth period in the high temperature season, and the production is generally ranked after the cucumber during the planting period.

2. Sowing time: winter melon is generally to be cultivated with seedlings, the seedling age is 40 50 days, and the appropriate sowing date can be determined according to the local climatic conditions, the purpose of cultivation and the type of variety, small winter melon can be sown in early February, and large late-maturing winter melon can be sown in mid to late February.

3. Soaking seeds to promote germination: winter melon seeds germinate slowly and the germination potential is relatively low, and measures such as high temperature scalding should be used before germination to make the seeds absorb water normally. The seeds germinate properly under the condition of 25 30 and can germinate after about 4 5 days.

4. Seedling management: winter melon seedlings grow slowly, and the seedling stage requires high temperature. In order to increase the bed temperature, the seedbed should be prepared in advance and the soil should be turned over. In order to meet its nutrient requirements, the bed soil should be prepared in advance, and should be mixed with more well-rotted organic fertilizer to make it loose and fertile.

5. Timely planting: The root system of winter melon is developed, and it should be deeply cultivated and leveled before planting to prevent water accumulation and cause blight and rooting. When planting, 3000 5000 kg of decomposed organic fertilizer should also be applied locally, and the density varies according to the cultivation method, climatic conditions and varieties.

Dig a pit and bury the melon seeds.

Winter melons are usually planted from January to March in spring and July to September in autumn. However, winter melon is cultivated in a wide range. Therefore, the planting time in each place is different, and the planting time is still based on the local time.

Generally, when planting, it is best to choose a place with good drainage and loose soil. Fertilizer is used more when winter melon is planted, so it is necessary to apply enough base fertilizer before planting. In this way, the yield will be higher when planting.

When planting it is time not only to apply enough fertilizer. Drainage measures are also indispensable when preparing the land. Winter melon needs a lot of water when planting, but if the water can't be discharged, it will cause various diseases of winter melon, so the drainage measures should be dug before planting.

When planting winter melons, it is most important to soak the planting with water overnight, and then you can take it out for planting. When planting, it is best to use the method of burrowing. After planting 1 or 2 seeds at a spacing of 35 to 45 between the seeds, it is time to cover the soil and water it.

This eliminates the need for transplantation after the seedlings have grown.

After the winter melon comes out, you can see that the seedlings of ** have not grown, and the seedlings should be replenished in time. When the seedlings are growing, there are more water requirements. Therefore, after the seedlings grow, they should be watered in time.

In this way, there is enough water to grow. After watering the seedlings, the seedlings should be watered once after 3 days have passed when the seedlings have grown.

After the seedlings have grown to more than 25 cm, it is time to build a rack for the seedlings. This can not only make the winter melon more ventilated, but also less diseased. It also saves the planting area.

After the bottom of the house is built, as long as the sprouts of the winter melon are placed on the shelf, it will grow on its own. After the seedlings are valued, it is time to fertilize the seedlings for the first time. This time, urea can be applied mainly in order to make the seedlings compete more quickly.

When the seedlings are about to bloom, a second fertilization is required. Phosphorus and potassium fertilizers can be used for fertilization this time. In this way, the petals have enough nutrients for fruit set.

After the winter melon sets the fruit, the vines of the winter melon should be thinned with flowers and fruits. Pinch off some useless stems to keep them ventilated. Pinch off some of the flowers or fruits that grow too densely, so that the remaining flowers and fruits can grow normally.

When the winter melon begins to swell in fruit set, it is necessary to apply the third fertilization. This time it is best not to use some kind of monoattribute fertilizer. It's best to use some fast-acting compound fertilizers.

Try to apply a small amount and more when fertilizing to avoid the situation that only seedlings grow but not melons after fruiting.

When the melon grows to the point that the leaves and rhizomes are a little yellow, it can be harvested. Don't wait too late for harvesting, otherwise the melon may die.

Winter melon planting row spacing and plant spacing, detailed explanation of planting techniques.

1. Winter melon likes temperature and is heat-resistant, the appropriate temperature for seed germination is 28 30, and the suitable temperature for seedling growth is 20 25. Winter melon is suitable for transplanting seedlings, and can be planted when 2 3 true leaves; It can also be planted at 4 to 5 true leaves, but the seedling age generally cannot exceed 40 to 50 days. Planting must be carried out when the average ambient temperature reaches 16 or more.

The sowing date is calculated according to the planting time and seedling age. In the middle and lower reaches of the Yangtze River, sowing is generally in early to mid-February.

2. Winter melon seed coat is thick and has mucus, which is easy to cause rot seeds if it is not well handled, and most of the seeds float on the water surface when soaking, and the germination is not neat when germinating, so winter melon is one of the vegetable seeds that are difficult to germinate. The commonly used method of soaking seeds is to soak the seeds of winter melon seeds in water for half an hour, scrub them repeatedly by hand, scrub off the mucus on the outside of the seed coat, soak the seeds in 50 60 warm water, stir while soaking the seeds, and reduce the water temperature to about 30. Since the winter melon seeds float on the water surface when soaking, they should be pressed with something when soaking.

After soaking seeds for a day and night, take them out to dry, and promote germination at 25 30 times, and scrub them with water once a day in the morning and evening during germination, and germination can occur after 3 or 4 days.

3. Winter melon has high temperature requirements, so when winter melon seedlings are raised, the seedbed should have a higher temperature, especially to increase the soil temperature. Can be used to brew hot hotbed and electric furrow seedlings, electric furrow seedlings are easy to operate, good effect, can be laid according to 100 120 watts of power per square meter, 50 60 grams of seedbed seeds per square meter, after sowing some water, so that the seeds and the soil contact, cover the soil 1 2 cm, cover the ground eggplant shed film, buckle the small arch shed. Energize and heat up to control the ground temperature at 20 25, when more than 50% of the top buds are unearthed, remove the mulch, and sprinkle some fine soil to prevent the seeds from "wearing hats".

After the seedlings are ready, reduce the soil temperature to 18 20 to prevent growth, and generally do not water before transplanting.

4. When the winter melon cotyledon turns from yellow to green, the seedlings are generally transplanted once, and the ground temperature is controlled at 25 28. After 3 4 days of slow seedlings, gradually reduce the temperature, which is conducive to cultivating strong seedlings. When the first true leaf is exposed, the soil temperature is controlled at 25 28 during the day and 18 20 at night, and the temperature is natural at day and night, so that under normal circumstances, except for the noon on a sunny day, the ground temperature is higher than the air temperature for a long time every day, and the development of the root liquid front and leaf area increases, which can inhibit the growth.

When the winter melon seedlings grow to one leaf and one heart, the temperature is controlled at 17 at night and about 22 during the day. When the seedlings are three-leaf and one-hearted, they can be planted. Pest control during seedling rearing is the same as cucumber.
