Small watermelon early spring cultivation technology

Planting time

Planted in the early spring in the protected area. Seedlings are sown in late February. The seedlings are 35-40 days old. The seedlings are warmed. They will be planted in the greenhouse in early April and mid-April and will be listed in early June.

Bare land planting in spring sowing from late March to late May, seedling age is about 30 days. Seedlings are cultivated in a protective field. After the final frost period, they are planted on bare ground or covered with small arch sheds.

Seeding

Nutrient soil preparation Nutrient soil preparation methods are many, usually 2/3 peat soil and 1/3 uncultivated field soil are mixed and sieved, or 1/3 rotten farm fertilizer and 2/3 field soil. Add 2 kilograms of superphosphate per square soil, and disinfect with 800 times Carbendazim, or fumigate with formaldehyde.

Seed soaking and germination can be sterilized by soaking in 55C warm water, and constantly stirring until the water temperature is about 30C. After soaking for 4 hours, the seeds are washed, then wrapped with a wet towel and placed in an environment of about 30C to promote germination.

Before sowing * Apply 800 times methyltobutine solution to water the seedling soil. When the seed buds grow to about 0.5 cm in height, sow in the seedling tray. When sowing the seeds, the seeds should be placed flat with the bud tips facing down and covered with 1.5 cm thick fine nutrient soil, and the seedling trays should be poured with 800 times methyltobutine solution, and the temperature should be maintained at 25-30C to ensure that the seedlings are neat. After emergence, the temperature can be maintained at 18-28C. The seedbed should be dry and not wet. Freezing damage should be prevented in early spring to ensure sufficient light.

Field management

The planting generally adopts a multi-vine and multi-fruit whole planting method, with a row spacing of 60-80 cm × 180-200 cm, and 530-730 plants can be planted per acre. It can also be planted with a vertical grid, with a row spacing of 50 cm x 100-140 cm, and double-row planting.

The fertilizer and water are mainly base fertilizer, supplemented by topdressing. Bottom fertilizer is applied or spread with 60 kg compound fertilizer and 3000 kg pig pen. In the future, it is necessary to apply vine fertilizer and bulking fertilizer throughout the growth period.

The whole vine leaves are small because of the small fruit. To achieve higher yields, multi-vine and multi-fruit methods should be used. Generally, 1 main vine and 3-4 sub-vines are kept. When the fruit is left, the * female flowers on the main vine are removed, and the rest can be used. Keep two stubble melons, and the vines should be removed as soon as possible.

Pest and disease control Small watermelon varieties have strong disease resistance. The common diseases are blight, blight, virus disease and anthracnose. Pest and disease control is conducted once every 7-10 days.
