Cultivation techniques of muskmelon in open field in spring

The open field cultivation of muskmelon in spring has the advantages of low input cost and easy management, so it is the best choice for farmers to increase their income in a short time. Optional varieties such as Xiangmi 900, Sabai series and so on. The main results are as follows: 1. After soaking the seeds and selecting the varieties, the seeds can be dried properly in fine weather, and then screened. Soak the seeds in warm soup with 55 degrees water for 1 minute, then lower the temperature to 25 degrees, then fish them out a little after 6 hours, and then accelerate the germination (the germination temperature is about 28 degrees). When the seeds germinate and show white, sow the seeds. 2. The 65-hole black hole plate can be used to raise seedlings, and the seedling age is about 35 days (the average temperature is above 15 degrees). The seedlings can be planted in the field at the age of 3 to 5 leaves. 3. transplanting in the first and middle of May, the planting density can be suitable according to the variety, pay attention to water management after transplanting, shorten the slow seedling period as far as possible, and hole watering, which can not only preserve the ground temperature but also provide sufficient slow seedling water. Cover with plastic film to moisturize and increase the ground temperature. Water-retaining agent can also be used when transplanting, which can reduce the number of watering, and can be watered again in the whole growing period. 4. Apply enough base fertilizer at one time, open a ditch 30 cm away from the plant, apply 50-100 kg potassium sulfate compound fertilizer per mu, or 2-3 square of mature livestock and poultry manure. Or 50-100 kg ternary bio-organic fertilizer, foliar spraying of potassium dihydrogen phosphate and Fengshou No.1 in the middle and later stages can balance vegetative growth and reproductive growth and improve fruit setting rate. 5. Apply 2-4 kg of tianoxijing or phoxim or avermectin per mu with fertilizer to control underground pests, nematode diseases or soil-borne diseases, and strengthen the prevention of virus diseases in the process of planting management. foliar spraying of phytopathrin and protective fungicides once every 10 days or so. 6, watering usually less watering, seize the critical period such as expanded melon water, at the same time to apply quick-acting compound fertilizer to ensure adequate nutrients of muskmelon, timely watering in case of drought. 7. Management should choose the appropriate way of pruning and pruning according to the characteristics of the variety, such as Xiangmi 900 can grow naturally without pruning and branching, while Sabai muskmelons need five vines to leave 3 or 4 melons. 8, taboo muskmelon mostly avoid continuous cropping, avoid watering when the soil is hot, avoid chlorine fertilizer, weeding during flowering period, avoid nitrogen fertilizer, avoid rape stubble planting, avoid planting under big trees. Hope melon farmers pay attention to and refer to planting to ensure a good harvest.
