Planting techniques and methods of reclaimed watermelon field

Most of the watermelon varieties cultivated in the greenhouse are early-maturing varieties, which creates time conditions for watermelons to bear melons again.

According to the experiment, after the current stubble watermelon is picked, the new vine can grow after cutting off 7-10 old vines, and the second stubble melon can be harvested in 40-45 days, with a yield of about 950 kg per mu, with considerable benefits.

1. Cultivate new vines

The method of cutting vine regeneration should be adopted for watermelon to bear melon again, that is, after the first stubble melon is harvested, cut off the old vine at 30-35cm from the root, use the latent buds in the basal leaf axils to germinate or leave 1-2 strong new vines at the base of the old vine, and the rest are cut off. With this method, the position of sitting melon is low, and the vine grows rapidly and exuberantly. Watermelon has the advantages of fast ripening, large type and high yield, which is 500-600 kg higher than other methods per mu.

2. High yield measures

(1) protect the root system. In the management process of fertilization, watering and weeding of the former stubble melon, it is necessary to carefully and carefully protect the root system from damage and grow normally and healthily.

(2) Fertilizer and water management. The first stubble melon was applied with available nitrogen fertilizer 3 days before harvest, generally 15-20g urea per plant.

Watermelon should be watered in time after harvest to promote the growth of new vines, expand the leaf area and create conditions for melon. When the plant has 80% melon, apply fertilizer again, generally applying 10 kg of potassium sulfate, 10 kg of potassium dihydrogen phosphate, 5 kg of urea or 500 kg of fully mature organic fertilizer and 20 kg of total compound fertilizer.

(3) clear the garden to prevent disease, after the first stubble melon harvest, clean up the field weeds, rotten melons, diseased plants, residual leaves, and remaining melons, and spray 500 times carbendazim or 600 times chlorothalonil and 0.2% urea continuously for 2-3 times to control the disease. The cut old melon vines should be transported out of the field in time, and the melon field should be cleaned up.

(4) pruning of new vines, generally using the method of leaving one melon per plant, because the old vines are cut off, the new vines germinate strongly, quickly and bear more fruit.

In order not to affect the normal growth of selected melons and to promote the rapid expansion and early ripening of the second stubble melons, the branches and small fruits born after vine cutting were all cut off so that nutrients were supplied centrally.

(5) other management is the same as conventional cultivation.
