Black melon melon high yield, high quality, resistance to storage and transportation, is a very promising variety of winter melon vegetables. The average yield is 8,500 kg per 667 square meters (1 mu). First, choose a deep sandy loam, sit north to south, sunny, not only have water irrigation, but also to ensure that the water can be drained within 4 hours of block fields, avoid continuous melons. Second, seed treatment and seedling soaking 1 day before the sun type 2 hours (9-10 morning or 16-17 hours). First soak in warm water of 55°C for 30 minutes, or dip in 50% solution of 50% carbendazim wettable powder 400 times for 30 minutes, wash and wash, then dip for 4 hours in 400-fold love solution, and then wash and wash. With gauze wrapped in the incubator germination. Each pack does not exceed 1 kg and the temperature is 30-32°C. It is best to use a thermostat to ensure proper temperature and humidity. Self-made incubators should be packed in thick cardboard boxes, installed with 40-watt bulbs and a thermometer, and the temperature inside the box should be adjusted according to the degree of opening and closing of the lid. The germination process is washed with water once a day, 3-4 days can germinate, germination of seeds can be live, but the management costs more work, not easy to grow seedlings, nursery seedlings should be used nutrition, especially in cold winter and spring weather, to use mulch Arch cover. Protect seedlings, currently promoting 88cm black plastic seedlings. The greenhouse seedling temperature should not exceed 35°C. Open the shed in sunny weather. Otherwise easy to grow tall seedlings. The nutritious soil was cleaned with a compost of compost and the sandy loam without melons was mixed by 1:4. 1% powdered superphosphate was added, and 0.1% compound fertilizer water was sprayed. The mixture was mixed and the germination seeds were laid flat. Soil 1cm, spray water to maintain semi-dry semi-dry state, dry at 10 o'clock in the morning, watering 1 time, melon seedlings grow a true leaf, with 5 kg of human waste watered 50 kg spraying, while spraying 70 % Thiophanate 800 times liquid to prevent disease. Insect pests were sprayed with 40% water-containing phosphorothiophene 1500 times. 2 true leaves can be transplanted into Daejeon. 3. Before the transplant, the site is well-prepared and finely grounded. There is no weed, and the field ditch is cut around the field scene. Grooves are planted at a distance of 70cm from the planter, and the furrows are planted to fill the soil (400kg of beef and sheep manure). Superphosphate 25kg) Plow the second furrow from the planting point of the melon seedlings in the direction of extension 30cm and apply the decomposed fertilizer to the back ground (chicken manure, cow manure 750kg, potash 25kg, and phosphate fertilizer 50kg). And then from the third furrow 30cm plow, under the application of compost fruit fertilizer back to the soil (farmers 250 kg, 50 kg of medicinal cakes, compound fertilizer 15 kg). Then the sorghum was leveled and a hole was planted in the first furrow. Fourth, colonization of 600 plants per 667 square meters. Before planting, sprinkle melon seedlings to prevent graft rooting. Don't remove the nutrient decidua during transplantation. Do not injure the root. Select a healthy seedling to plant at each hole. When soil is used, use your hands to compact the soil around the plant so as not to affect the growth of the root and prevent it from breaking or scraping. The back ground was slightly higher than the acupuncture point. Prevent water and rot from rooting, and apply enough water after planting. The nutrition cup membrane cleared out of the park. Fifth, pressure vines use the roots of the gourd joints to carry out pressure vines so that adventitious roots form secondary absorption groups and increase nutrient supply. Pressing vines when the main vines grow to 60cm, the squaring face deep 3cm, the main vines 6-7 with soil pressure, do not hurt melon vines or melon leaves, vines after two weeks began to produce new roots, one by one to form the root group After the vines are pressed, they cover the straw and suppress evaporation and weeds. Sixth, scaffolding with iron wire, fishing nets can reduce the cost, but the best cross-bracket. Ventilation ventilation conducive to the growth of melon, but also easy to manage operation, the stent with a long 2.5 meters of wood or a large bamboo cross cross-frame, due to the weight of black melon melon, to set the rods to hang melon, cranial attention to integrity, neat Shelf. Seven, leaving the fruit in the main vines 18-20 when the female flowers, after every 4-5 ginseng a female flower, to stay in the best section of the melon is 28-35 section, choose to leave a symmetrical between the melon However, it is affected by the weather at this stage. It is necessary to remove excess melons until the implementation is finalized. Only in this way can high yield be achieved. After the fruit is set, leave 10 leaves into the main vine topping heart. All side vines are removed to avoid competition with the main vine. Attention should be paid when side vines are removed. To avoid wound infection. VIII. Pollination If the weather is good and the temperature is high, wax gourd can be pollinated by the honey bee, but the melon blooms, the temperature during the fruit setting period is low, and the bee activity is very small. It must be pollinated artificially. The pollination should be done before 9:00 a.m., and the action should be light and non-abrasive. The hair of the young melon, otherwise it is easy to yellow and drop fruit. Each male pollinated 3 female flowers. Nine, fertilizer and water management seedling stage, pumping vines require less fertilizer, fruiting period, especially fruit set, it will have sufficient fertilizer and water, fruit development, the demand for fertilizer and water and reduced, in addition to the first stage under the foot fat meal, management 200 kg of compound fertilizer is needed throughout. The top dressing distribution is: 30-40% before pumping. The flowering period is 60-70%, and it is finished in the middle of the result. After fruit set, potassium dihydrogen phosphate, urea, and compound microelement fertilizer were sprayed together to prevent and control insecticides. (Baoqing County Seed Field Huang Deqing)
