What season is suitable for growing watermelons in South China?

The best season to grow watermelons in South China is to raise seedlings during the Spring Festival and sow in February and March. As long as the temperature can be between 18-35, it can be planted continuously.

1. Live broadcast in the open air

After Tomb-Sweeping Day, it basically entered the frost-free period, and the temperature rose rapidly. Watermelon in the open field can be directly sown with dry seeds or directly sown with big buds after germination. This planting method does not require early maturity, and mainly focuses on high-yield cultivation. Generally, early-maturing or mid-late-maturing varieties with high quality, big fruit and high yield are selected.

2. Plastic film mulching cultivation

There are two ways: "direct seeding with plastic film" and "planting seedlings in advance with plastic film". Now, in some places, it is very good to adopt the cultivation method of "covering the ground first and then covering the ground" with plastic film. Watermelon covered with plastic film was planted in first frost in mid-April. The harvest time is 7~ 15 days earlier than that of direct seeding in the open field, and the yield is increased by about 30%. Generally speaking, middle-maturing or early-maturing varieties are the main varieties.

3. Small arch shed cultivation

On the basis of plastic film mulching, arch shed and plastic film mulching are generally used. Most seedlings are raised first and then planted, and can be planted in the middle and late March. If you cover grass in the shed at night, the planting period can be advanced to the beginning of March, and it can be listed in early June. Because of the early listing, you can leave two crops and have high economic benefits. The main purpose of this cultivation method is to pursue early maturity and high price, and at the same time give consideration to the yield of the second crop of melon. Therefore, it is required to choose varieties with low temperature tolerance, early maturity and good second-crop melon.
