Cultivation Techniques of Postharvest Extension of Watermelon

Fertilization at seedling stage

No fertilization at seedling stage, less or no application of increased cranberry fertilizer, swelling of melon fertilizer can be applied more properly. Usually combined with 667 square meters of water applied urea 7.5-10 kg, potassium sulfate 5 kg

Post fertilization

Late to prevent premature aging, with 0.2% -0.3% potassium dihydrogen phosphate solution for extra-root fertilizer. For the water should be dominated, and beware of melon fields

Pruning

The double vine pruning method should be used to select a strong side vine on the main vine base at 3-5 knots, and remove the remaining direction. After the main vine on the young cucumber is stable, the main vine growing point can be removed.

Artificial pollination

At 6-9 a.m. each day, the male flowers that are open on the day can be removed, and the petals are peeled off. Evenly, the stigmas of the female stigmas should be applied uniformly, but the ovary and hairs should not be damaged.

Cover a small shed

After entering the result period, the temperature dropped and the film should be covered with insulation at a proper time. More than a small arch cover, arch shed 40-50 cm wide and 1 meter wide.

After covering the first vine, the melon body is coiled to the left so that the length of the melon body does not exceed 1 meter. Then the arches shall be inserted on both sides before and after the plant, and the film shall be covered with a tight soil around it.

Cover the early morning sunny morning when the outside temperature reaches 25°C, open the ventilation on the leeward side of the arch shelter and cover it again at about 4 pm; in the late days, it will only be ventilated at noon on sunny days.

Period fertilization, pruning, snoring and artificially assisted pollination to cover small sheds.
