When is the best time to plant watermelon? What are the planting methods?

Watermelon is a good fruit in summer. Watermelons in China are the most famous in Xinjiang, Lanzhou, Gansu, Dezhou, Shandong, Liyang, Jiangsu and other places. So when was the watermelon sown and what are the planting methods? Next, let's tell you.

The best sowing time of watermelon is that the planting time of early spring watermelon and greenhouse watermelon is from March 10 to 20, the watermelon in small and medium-sized greenhouse can be delayed by about ten days, and the watermelon in solar greenhouse can be five or six days earlier than that in greenhouse. The management of watermelons in protected areas in early spring should be strengthened after planting, and the key points of management are temperature, humidity, fertilizer and water, flower and fruit protection. There are summer sowing and autumn harvest season of watermelons, when the climate is warm, but also coincides with the National Day Mid-Autumn Festival, market consumption is larger, the price is also higher, has a certain development prospects. The sowing date of autumn watermelon is relatively strict. Jiangxi generally matures normally in the middle and last ten days of July, but it is more safe to sow in early July. Proper early sowing can increase fruit shape and sugar content.

Now there are many kinds of watermelons on the market, and they are very chaotic. Some units often exaggerate the characteristics of watermelon varieties, such as disease resistance, fruit size, sugar content, yield and so on. Therefore, it is reminded that melon farmers should not only read the introduction on the packaging, but also know more about the variety, such as the source of the variety, breeding units and breeders.

For the cultivation of watermelon, we should first choose the suitable environmental conditions for watermelon growth. The suitable growth temperature of watermelon is 18 ℃-32 ℃. Watermelon is a drought-tolerant crop, but it needs a lot of water during the whole growth period. Especially in the growing, spreading and expanding stages, especially to meet the water demand, good quality and high yield can be obtained. Sufficient light is also the most important condition for the cultivation of watermelon. During the whole growth period of watermelon, at least more than 600 hours of light is needed to meet the needs of growth, flowering and fruiting. Watermelon is a deep-rooted crop with delicate root system, dry tolerance and moisture tolerance, so it should be cultivated in sandy loam with good drainage, deep soil layer and fertile soil quality.

Planting watermelons can not only be direct seeded in the field, but also can be raised and transplanted. Seedling transplanting, generally the seedling age is between 20 and 30 days, then the seedling sowing should be 20 to 30 days before the late frost period. Seedling breeding must have protective facilities, and now small arch sheds are often used, and electric hotlines are laid under the nutrition bowl beds in the arch sheds. The nutrient bed soil for raising seedlings should have water retention and good ventilation, at the same time contain appropriate amount of nutrients and there is no hidden danger of diseases and insect pests. Cotyledon seedlings can be cultivated with clods, while large seedlings must be cultivated in containers, such as paper bags, plastics and flowerpots. When cultivating large seedlings with 3 leaves and 4 leaves, the diameter of the container should not be less than 8cm, and the height should be about 10cm.

Finally, we should also pay attention to the timely picking of diseases and insect pests, so that we can eat sweet and delicious watermelons in the hot summer.
