(1) Reasonable choice of land and sugarcane and melon varieties. In other words, it is appropriate to choose a fertile ground cover with deep soil and good drainage. Sugarcane is selected from medium-mature, high-yield, high-sugar, and high-stalking varieties; watermelons are selected from varieties with early maturity, good quality, and high flowering rate. (2) timely transplanting seedlings. Sugarcane should be "double-film-covered" in early March; watermelon should be nursed in late March with nutrient-encapsulated seedlings. In the first half of April, the surface climate is stable at 16°C. Daejeon can be transplanted, sugarcane can be planted on the side, and watermelons can be used. . Sugarcane alfalfa width 1.8 meters, watermelon plant spacing 60-70 cm, 450-500 acres of fixed strains. (3) Deeply plowing soil preparation and applying basic fertilizer. In the winter, the sugarcane fields must be deep-turned. After spring, 800 kg of pigs per mu, 10 kg of superphosphate and 7 kg of urea are fully applied to the center of the cane rake and dig to the ground as the base fertilizer. Side can open a good planting cane ditch, per acre and then into the human pig fat 600 kilograms, superphosphate 30 kilograms, urea 10 kilograms or compound fertilizer 50 kilograms. (4) cover the film. Implementation of cane and melon mulching film cover. (5) Strengthen fertilizer and water management and pest control. In the end of May, when the watermelon fruit set was 4-5 days, 700 kg of pig manure and 8 kg of urea were applied per acre to promote the expansion of fruits and vegetables, and attention was paid to the prevention and control of diseases and insect pests in gutter drainage, grass cover, pruning and sugarcane melon cultivation. In mid-June, when watermelons are harvested and vines are harvested, timely lifting of the cane, cultivating, and full-fertilizing of the cane are required in order to achieve double high yields of the cane.
