In recent years, the demand for wax gourd has been increasing throughout the country. The spring wax gourd is rich in nutrients and high in yield. The yield of some varieties can reach up to 10,000 kilograms and the economic benefits are good. The spring techniques for the cultivation of wax gourd are described below. (l) Biological characteristics The whole growth period of wax gourd is 140-200 days. It usually takes 50-70 days for fruiting period. The wax gourd is a thermophilic and heat-tolerant vegetable with a suitable temperature of 20-30 degrees Celsius. The optimum temperature for the vine growth and flowering is 25 degrees Celsius. Melon needs more water, not tolerate early, and the growth period requires sufficient water supply. During the whole growing period of wax gourd, nitrogen is the most, followed by potassium, and phosphorus is a little less. Each producing 5,000 kg of wax gourd requires 30-36 kg of nitrogen, 24-30 kg of potassium, and 24-26 kg of phosphorus. Spring planting varieties are: (a) Daqingpi. Fruit weight 15 - 20 kg, per mu 3000 -4500 kg; (b) Hunan Hou Chi Chong Dong melon. The fruit weight is 40 - 50 kg and the mu yield is 5,000 - 10,000 kg; (c) Jufeng No.1. The fruit weight is 40 - 50 kg, and the yield per mu is about 6000 - 10000 kg; (d) Black skin melon. The weight of single fruit is about 13 - 15 kg, and the yield per mu is 3000 - 3500 kg; (e) Dongguan black melon. The fruit weight is about 10 - 15 kg, and the yield per mu is about 3000 - 3500 kg; (f) Precocious flour. The fruit weight is 13 - 20 kg and the yield per mu is more than 5,000 kg. (2) Cultivation techniques 1 Select melons should be cultivated on sandy loam soil or clay loam with deep soil, loose soil, good drainage, and strong water retention and fertility conservation. At the same time, it should be avoided as a melon crop (preferably several years Uncultivated melon crops are planted on plots to reduce the incidence of disease. 2 Sowing (a) Select sowing time. Spring wax gourd should be sown in late January-early January, so that it can be used in the morning market and high yields can be obtained. (b) Immersion germination. Soak melon seeds in warm water at 55 degrees Celsius, maintain a stable temperature for 15 minutes, then allow them to cool to 30 degrees Celsius, continue soaking seeds for 10 -12 minutes, wash seeds after soaking, and then combine seeds with moist sand. Germinate at a temperature of around 30 degrees Celsius until the seeds are white and the shoots are 0.3 to 0.8 centimeters long. Note that during the germination process, the seeds should be turned frequently and kept moist to facilitate sprouting. (C) sowing. The melon planting - generally using seedling transplanting methods, should be disinfected when disposing nutritious soil. For every 1000 kg of nutrient soil, use 50% carbendazim WP 25-30g to dissolve in water, spray and mix nutrient soil. Cover with film for 2 - 3 days before use. (3) Planting 1 Soil preparation for planting, with a width of 2 m, a width of 0.4 m, and a height of 0.5 m, applying organic fertilizer in the middle of the gully, and 1000 m/mu of soil-fertilizer. 1500 kg, superphosphate or peanut bran 50 kg, before planting 1,000 kg of compost per acre, 30 kg of superphosphate or 20 kg of compound fertilizer. 2 The colonization was planted in a single row and planted in the center of the plant surface with a spacing of 80 to 100 cm. (4) Field management 1 Selection of cultivation methods There are 3 melon cultivars, including gourd, shed gourd and melon. Combining the actual conditions, generally using greenhouse melon cultivation method, the shed height should be 1.8 - 2 meters. 2 Whole vines, vines, and mango vines depend on the result of the main vine, but the melon twigs are strong and should be whole vines. Before and after fruit setting, all lateral vines are removed, and after the fruit is set, some leaves are preserved. Melon vines are mainly taken by each plant in their own circle spacing within the distance from the plant, gourd after the shelves, it is necessary to divert vines, so as not to break vines. Large melons should be crushed at the same time as the vines are introduced. In the soil under the stem sections, shallow ditches of 5–10 cm should be dug, and the 1.6–2 m vines growing in circles around the stems should be covered with fine soil. 3 fertilizer and water management (a) reasonable top dressing. When melon dressing, attention should be paid to the reasonable cooperation of nitrogen, phosphorus, and potassium. Plants can grow vigorously without chasing or chasing. If the leaves are pale or yellow, fertilizer should be top-dressed in time. Before the growth of wax gourd, top dressing should be done. Water and fertilizer should be controlled before and after the opening of female flowers. , 1 - 2 melons should be re-fertilized after fruit set, 15-20 kg urea and 15 kg compound fertilizer per acre, and then top dressing every 2 weeks before harvesting 1 fertilizer, the amount of fertilizer can be reduced appropriately. (b) Moisture management. After entering the mango cultivar, the melon plunged into a larger amount of water and should be filled with horse water for one time. The flowering period is like no watering or less watering. The maximum amount of water is needed during fruit enlargement and the soil should be kept moist to ensure the yield. (5) Pest control 1 Disease prevention and control Phlegm failure is controlled by spraying 70% dexamethasone 300 times, 75% chlorothalonil 800 times or 70% early tyto-tribute 800 times; Manganese zinc 300-500 times, 72% Precizer 800 times or 72% Dupontco WP 600-800 times spray control; Powdery mildew 20% Triadimef 2000 times or 75% chlorothalonil 700 times liquid spray control; anthrax with 70% early jiujiubuzin 800-1000 times or 50% carbendazim 1500 times liquid spray control; sunburn disease covered with fruits or other materials, reduce direct sunlight. 2 Insect pest control Thrips is controlled with 18% insecticide bihydrate 250-400 times liquid or buprofezin 1000 times liquid; observing melon with 90 % crystal trichlorfon 800 - 1000 times liquid or 90% bataan wettability The powder was sprayed with 1000 - 1500 times of liquid to prevent and control; 40.7% of the locusts were sprayed with 1000 times of Lethbene, 50% of baicaleone 1000 times liquid or Bacillus thuringiensis preparations, and 40.7% of the fruit fly was tested. 1000 times liquid, 90% trichlorfon 1000 times or 80% dichlorvos 1000 times liquid spray control; fleas with diclofen 1500 times or 73% g fen enemy 2000 times liquid spray control.
