I. Planting Time
It is reported that watermelon is usually planted in March to April. The early maturing varieties are planted in mid-March, and the late maturing varieties are postponed to late April. The climatic conditions at this time are more suitable for the growth of watermelon, which can make it germinate faster. However, there are also autumn sowing, which is counter-seasonal watermelon.
II. Management Methods
1. Land Selection
It is suitable to choose sandy loam soil with deep soil layer, loose and fertile soil, and convenient irrigation and drainage. The field should not have planted melon crops in the past 5 years for dry land and 3 years for paddy field.
2. Land Preparation and Fertilization
Deeply plow the watermelon field before winter and prepare the land before transplanting. The watermelon field should have three ditches to keep the field dry after rain and the soil loose and flat.
3. Transplanting
The day before sowing, water the seedling tray thoroughly in the afternoon. When sowing, place the germinated seeds flat in the seedling tray, one seed per tray, cover with 1 centimeter of fine soil, and cover with a film.
4. Pruning and Pressing Vines
Generally, a three-vine pruning method is adopted. When the main vine has 8-9 leaves, select the main vine and two strong lateral vines, and remove all other daughter vines and granddaughter vines.
5. Setting Fruit
Select the second and third female flowers on the main vine or the first and second female flowers on the lateral vines to set fruit.
6. Topdressing
When the young fruit is as large as an egg, fertilize according to the growth of the plant. Generally, apply 45% nitrate sulfur or potassium sulfate controlled-release fertilizer 15-20 kg per 667m2.
7. Water Management
In the seedling stage, try to reduce watering, or even not water, to promote the formation of a developed root system. Control water before flowering and fruit setting to prevent excessive growth. After fruit setting, ensure sufficient water supply to facilitate fruit expansion and increase weight.
8. Harvesting
Harvesting should be done in the morning, preferably on a sunny day.
