Planted in mid-March and put on sale in early July, such as early spring ruby; Late-maturing varieties are sown in mid-April and harvested in August, such as Xinong No.8; If the seeds are sown in late June, they will not be harvested until September and October in autumn.

Watermelon planting method:

First of all, you need to dig a hole every 50 cm on the ridge of the selected land, then take the cultivated watermelon seedlings out of the Petri dish and put them into the hole dug in advance, and then you need to water them. After watering, it is necessary to cover the watermelon seedlings with a thin layer of fine soil to avoid evaporation or loss of water.

Water watermelon at least 3-5 times in the whole growth process, and water it in time after stretching to avoid water shortage and inhibit the growth of watermelon seedlings. When the watermelon grows to the size of a fist, it needs to be watered in time, which can ensure the normal growth of watermelon and thus have better quality.

No matter whether it is watering or raining, we should pay attention to the fact that there is no water in the field, which may lead to poor root respiration and death of watermelon seedlings. Because watermelon is a fertilizer-loving crop, it is necessary to ensure sufficient fertilizer on the premise of ensuring sufficient water. Generally, it only needs topdressing twice. It is recommended to use 20-25kg urea and 0/0-/0/5kg potassium sulfate per mu.
