Spring melon open field cultivation has low input cost and is easy to manage, which is the best choice for farmers to increase their income in the short term. Optional varieties such as Xiangmi 900, Shabai series, etc.
Soaking seeds
After selecting a good variety, it can be properly sun-dried in sunny weather and then screened. Soaking in warm soup can be soaked in 55 degree water for 1 minute, then cooled to 25 degrees. After 6 hours, remove it in 100 times solution of new high fat film (can evade underground pests, isolate virus infection, strengthen respiratory intensity, increase seed The germination rate) is slightly dry, and then germination (the germination temperature is controlled at about 28 degrees). When the seeds are germinated, the seeds are sown.
Nursery
65-hole black seedling tray can be used to raise seedlings (average temperature above 15 degrees) and seedling age is about 35 days. It can be planted in Daejeon at the seedling age of 3 to 5 leaves.
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. After transplanting, 600-800 times of new high-fat film can be sprayed on the seedlings and the ground to prevent the water from evaporating on the ground, the moisture of the seedlings is not transpiration, the pests and diseases are isolated, the seedling period is shortened, the new environment is quickly adapted, and the watering can be reduced. frequency.
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. Or ternary bio-organic fertilizer 50-100 kg, the young fruit period begins to spray the strong melon tiling liquid to increase the fruit pedicle, improve the nutrient transport, prevent falling flowers, fruit drop, cracked fruit, stiff fruit, deformed fruit, etc. (every 7- Spray 3 times in 10 days).
Medication
With the fertilizer, 2-4 kg or phoxim or avermectin can be used to control underground pests, nematodes or soil-borne diseases. The prevention of viral diseases should be strengthened during planting management. Foliar spray application of plant disease + new high lipid membrane protection every 10 days or so.
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.
management
Due to the characteristics of the variety, the appropriate pruning method is adopted. For example, Xiangmi 900 does not need to pruning and snoring, and can be allowed to grow naturally; while Shabai series melon needs five to four whole melons.
Taboo
Most melons are not heavy, avoid watering when soil heat, avoid chlorine fertilizer, avoid weeding during flowering, avoid applying nitrogen fertilizer, avoid rapeseed cultivation, avoid planting under the big tree.
