1. Soaking seeds. After selecting a good variety, it can be properly sun-dried in sunny weather and then screened. Soak the seeds in warm soup for 1 minute, then cool down to 25 degrees. After 6 hours, remove and dry slightly, then germination. (The temperature of the germination is about 28 degrees.) When the seeds are germinated, the seeds are harvested.
2, nursery. Seedlings (average temperature of 15 degrees or more) are about 35 days old. It can be planted in Daejeon at the seedling age of 3-5 leaves.
3. Colonization. Transplanting in mid-May, the planting density can be used according to the variety. Pay attention to water management after transplanting, try to shorten the slow seedling period, and pour the hole, which can not only maintain the ground temperature but also supply sufficient seedling water. Cover the mulch to moisturize and increase the temperature. Water-retaining agent can also be used during transplanting, which can reduce the number of watering, and can be re-watered once in the whole growth period.
4. Fertilization. The base fertilizer is applied once, and the ditch is 30 cm away from the plant, 50-100 kg of potassium sulfate compound fertilizer per mu, or 2-3 squares of decomposed livestock manure. In the middle and late stages, foliar application of potassium dihydrogen phosphate and other supplements can balance nutrient growth and reproductive growth and increase the fruit setting rate.
5, medication. With the application of 2-4 kg per acre or phoxim or avermectin, to control underground pests, nematodes or soil-borne diseases; in the process of planting management, the prevention of viral diseases should be strengthened, every 10 days or so Foliar spray 1 time.
6, watering. Usually watering less, catching key periods such as expanded melon water, and at the same time, chasing quick-acting compound fertilizer to ensure sufficient nutrients of melon and timely watering in case of drought.
