How much is the price of winter watermelons per jin?

With the development of planting technology, watermelons are also available all the year round. Today happens to be the Beginning of Winter, so the price of winter watermelons is more than one jin? According to the relevant market, we can learn that the price of watermelon has risen recently, and the prices of different varieties are also different.

Second, how to grow watermelons in order to achieve high yield?

1. Land preparation and base fertilizer

The soil was deeply turned and whitened for half a month, and then the soil was sprinkled with 50kg quicklime per mu, and then the broken soil was made into a 2.5m trench with a height of 40cm on one side and an inclined border of 20cm on the other; a planting ditch with a depth of 25cm and a width of 40cm was dug on one side of the high border, in which 1000-1500 kg of rotten farm manure, 25 kg of ternary compound fertilizer, 1.5 kg of borax and 4 kg of magnesium sulfate were applied per mu.

2. Select improved varieties

Improved varieties are the premise of high yield and high quality. Rational distribution of early, medium and late ripening varieties can prolong the supply period of watermelon and improve economic benefits.

3. Seed treatment

Sun the seeds for 2 days before sowing to increase the physiological activity of the seeds. Soak the dried seeds in about 55 ℃ of warm water for 6 hours, pour clean water, wash the seed coat with 5% lime water, gently rub with hands until the seeds are not slippery, then rinse with clean water, and air-dry moisture to accelerate germination.

4. Sprouting

Can use greenhouse germination, electric blanket germination, quilt germination and body temperature germination and other methods. The planting area is large, which can be accelerated by greenhouse, electric blanket or at the same time with corn and rice. Budding can be accelerated by body temperature and quilt heating for beginners. 5. Sowing seeds

Put the germinated one-meter-long seed flat on the nutrient soil of the prepared nutrition cup, sprout down (because the bud is the root), put only one germinated seed in each nutrition cup, and cover it with 1 cm thick nutrient soil. sprinkle a little 1000 times topzine water (or other fungicides). Insert the bamboo, cover the film, and press the film with fine mud around it. Then insert another layer of bamboo, about 15 centimeters apart from the first layer, cover with a layer of film, and then press the film around with fine mud. During this period, the temperature in the shed should be kept at 22 ℃ 28 min. After the first true leaf grows, the temperature can be cooled gradually. A few days before emergence, it was lowered by 1 ℃ per day and finally kept consistent with the natural temperature in order to adapt to the natural temperature after planting.

6. Watering

Watermelon watered at least 3 times during the whole growing period, the leaves increased after the watermelon stretched, the sunshine time was long, and the water demand increased, so it was necessary to water the watermelon once. When the young melon grows to the size of the fist, pour the expanded melon water well to ensure the yield and quality of watermelon and normal growth and development. In the future, we can decide whether to water or not according to the climate and soil moisture at that time, and stop watering a week before harvest.

7. Topdressing

Watermelon is a fertilizer-loving crop, and rational fertilization is one of the important measures to ensure high quality and high yield of watermelon. The general principle is: careful application of seedling fertilizer, skillful application of vine fertilizer, re-application of expanded melon fertilizer. Topdressing is mainly quick-acting fertilizer.
