Everyone knows that pumpkin is no stranger to butter. But do you know butter pumpkin? The following Hui Nong network Xiaobian will take you to look at the cream pumpkin and its soilless cultivation techniques in Meizhou, Guangdong. In 2015, the Meizhou Green Fresh Eco-Agricultural Park was introduced to carry out the research on soilless culture of 607 cream pumpkin. The summary of a set of mature pumpkin pumpkin soilless cultivation technology has achieved good results. The output of 667m2 is 4000kg and the output value is 1.2~1.8 million. The annual net income is more than 20,000 yuan, and the investment recovery period is 2 years. 1, the characteristics of butter pumpkin Creamy pumpkin is a short-light crop with a light growth rate of 17~28°C. The suitable temperature for seed germination is 25~35°C, and the suitable night temperature is 18~25°C. It has strong adaptability to climate and is more resistant than other melons. Low temperature, high temperature and drought tolerance, the optimum pH value is 6.4, the yield of 667m2 is over 4000kg, and the planting of 800~1000 seedlings is 667m2. 2, sowing and seedling 2.1 Disinfecting with formalin 1000 times solution soaked for 30~60min, then washed, or soaked in warm water at 55 °C for 30min, and continue to stir, after about 3 hours, the seeds are washed in clean water for 2~3 times. 2.2 The seeds are germinated and picked up with a wet towel. At 28~30°C, the shoots are germinated for 2~3d, and the bud length is no more than 0.5cm. 2.3 Seeding Place the germinated seeds in a 5cm×5cm×5cm sponge block that has been soaked for 1h before placing them on the seedling tray. At a temperature of about 25°C, pour water once a day in the morning and evening, keep it moist, 3~5d Out of the seedlings. 2.4 After seedling emergence, use 500 times of thiophanate for 1 time and spray with low concentration insecticide once. After 3~4 days, rinse the roots of the seedlings with water, wrap the roots of the seedlings with a sponge block, place them in the planting cup, concentrate them in the cultivation tank, and raise the seedlings with 1/2 flow standard nutrient solution. 3, colonization After 7 to 10 days in the cultivation tank, when the leaves are grown to 2 pieces of true leaves, the nutrient cups are placed in the cultivation tank and soaked in the nutrient solution. Planting specifications, plant spacing is 60cm × 40cm. 4. Management of nutrient solution The nutrient solution formula can be selected from fruit or general formula. The nutrient solution management maintains the pH value of 5.5~6.5 during the whole growth period, EC=1.0~1.5ms/cm in the seedling stage, and EC=2.0~2.5ms/cm in the growth period. 5, plant management 5.1 Introduction of vines: When the pumpkin has 7~8 pieces of true leaves, the vines are roped. 5.2 Pruning: Generally, the single vine pruning method is adopted. The side vines of the nodes below 100 cm are all removed, and the above nodes are left with 3~4 side vines, and the rest are removed. 5.3 Pollination: Artificial pollination after opening female flowers. 5.4 Remaining melon: The main vine leaves 1 melon per 1 section, and 1 side melon on the side. 5.5 Topping: The main vine generally leaves 30 pieces of leaves to pick the heart, and the side vines are left behind. 5.6 Thinning: Remove the deformed fruit and mechanically damage the young fruit. 5.7 Picking leaves: Remove the old leaves and diseased leaves of dried yellow. 5.8 Harvesting: It can be harvested about 45 days after flowering. 5.9 Pest Control: The main diseases of pumpkins are virus disease and powdery mildew. The most common measures to prevent and control viral diseases are to control and eliminate aphids. If the diseased plants are found to be removed early, powdery mildew can be used with 50% carbendazim 600 times solution or methyl group. Bujin 1000 times liquid, spray once every 7d, even spray 3 times, can be used alternately. Insect pests include aphids and yellow squashes. The insect pests can be 6% Ai Shishi 1000 times liquid, 3% acetamiprid 1000 times liquid, 7~10d spray once, and even spray 3 times. The above is the Xiaobian net Xiaobian finishing about the Guangdong Meizhou cream pumpkin and its soilless cultivation techniques, have you learned?
