1 Select high-yield and high-quality varieties such as Meikang No. 9 and Zihua Huabao that use early-middle-maturing and easy-to-eat cucumbers. 2 Cultivate strong seedlings in the middle of February in the Yangshuo greenhouse. Take fertile field topsoil and high-quality decomposed farmhouse organic fertilizers that have not been planted in Solanaceae and melons within 2 to 3 years, and nutrient soils are prepared at a volume ratio of 3:1. Diluted potassium dihydrogen phosphate 850 grams, urea 400 grams, potassium sulfate 150 grams per 1000 kilograms of nutrient soil, 50% phoxim EC with 800 times liquid and 36% thiophanate-methyl (thiophanate) suspension The agent 500 times evenly sprayed into the nutrient soil for insecticidal sterilization. Seeds were soaked in warm water of 65°C for 15 minutes before sowing, and stirring was continued. The stirring was stopped when the water temperature dropped to 30°C, then soaked at room temperature for 6 to 8 hours, then soaked in 0.1% potassium permanganate solution for 15 minutes, and the dosage was submerged. Seed for the degree, then rinse with water, wash out the mucus on the seed coat, drain the water and wrap it in a wet towel, place it at 28～32°C, germinate, and rinse with water 1 or 2 times a day during the germination. Wait 60 % Seeds can be sown when exposed. The nutrient bowl filled with nutritious soil will be poured into the bottom water. One seed will be placed in the center and a 1.5 cm thick nutrient soil will be covered after sowing. Then spread a layer of phoxim poisonous soil on the bed to kill the underground pests and cover the small shed. After sowing, the bed temperature is maintained at around 28°C during the day and 18°C ​​to 20°C during the night. After the seedlings are unearthed and before the third true leaf, the temperature cannot be higher than 25°C during the day and 14°C to 15°C during the night. 3 Planting deep ploughing and soil preparation, combined with deep ploughing of high-quality rotten farms per acre, include 6,000 kg of muscle fertilizer, 150 kg of superphosphate, 15 kg of urea, 25 kg of potassium sulfate, and 50% phoxim EC per acre before the depression is flattened. 0.1 kg, 30 kg watered for spraying to kill the underground pests, if the soil moisture is poor, can be filled with water once. Then ridging film, ridge height 20 cm, ridge width 70 cm, ridge distance 120 cm, ridge width 50 cm, ridge cover 90 cm wide film. 15 to 20 days before planting, the shed film is used to improve the temperature and security of the shed. During the planting period, the average daily minimum temperature in the plastic greenhouse should be stable above 13°C, and the soil temperature should be above 12°C. The local area is generally planted in the middle and late March. Colonization was performed in a single row, with a ridge (line) distance of 120 cm and a spacing of 60 cm. The planters were planted with a transplanting device and 926 plants per acre were planted. The planting depth was the same as the height of the nutrient bowl. The planting water was planted on the side of planting, and the seedlings were graded and the sick and weak seedlings were removed. 4 After planting, the daytime temperature was kept at 28-30°C and 12°C at night. Extend the vine to the flowering period, the daytime temperature is 23 ~ 27 °C as well, can not be higher than 28 °C, the night temperature of not less than 15 °C. When the greenhouse temperature exceeds 32°C, it gradually releases air, and it is strongly advised not to suddenly increase the wind to prevent flash seedlings. The air outlet is closed when the temperature of the shelf falls to 20-22°C. During the period from the melon period to the melon period, the temperature during the day is maintained at 30-32°C, and it is appropriate for about 15°C at night. After the melon sits steadily, the melons can be filled with water, and the swollen melon can be applied. The melons can be watered 10 to 12 cubic meters per mu, and the decomposed farmyard manure or chicken manure can be used for 1500 kilograms, the oil residue 300 kilograms and the ternary compound fertilizer 20 kilograms. Pouring 3 times of water 15 days before harvesting, 1/3 of the above fertilizer was applied to the roots of the watermelon before each watering. When the second or third female flower of the main vine is open, pollination is conducted at 9:00 to 11:00 am, and each male flower grants 2 to 3 female flowers, leaving only 1 melon per plant. Generally double vine pruning, in addition to retaining the main vine, in the base of the plant from 1 to 4 leaves a strong lateral branch as a secondary vine, in the main vine after 9 leaves a melon, if the melon can not sit on the vice vine to stay melon Pressure vines are carried before the young melons sit. When the young larvae reach the big fists, they can pick up the heart from the main and vice vines to promote the growth of the young larvae. With the expansion of the melon, under the melon pad dry soil or hay, etc., when the watermelon grows to a large bowl mouth every 5 to 7 days turn 1 melon, so that the melon shape round, uniform coloring. Fold the melon to be soft in the afternoon and carry the cucurbit handle to avoid touching the melon.
