To cultivate watermelon in an energy-saving solar greenhouse, to achieve high yield and quality, we must grasp the following links: 1. Choose medium-sized or small melon hybrid varieties with strong growth, strong adaptability, more female flower nodes, moisture resistance, disease resistance, high yield, high quality, thin skin and strong toughness, storage and transportation resistance, suitable for dense planting. 2. Scientifically regulate the light, temperature and humidity in the facility so that each growth stage of the watermelon plant is in the most suitable ecological environment for growth and development, improve photosynthetic efficiency, and promote the growth and development of plants and fruits. 3. Reasonable dense planting, hanging seedling management, and scientifically spreading vines, as soon as possible to increase the early leaf area of ​​watermelon plants, increase, and maintain a suitable leaf area coefficient (about 2.5). 4. According to the characteristics of watermelon growth and development, according to the principle of "promoting, controlling and promoting", we should do a good job in soil, fertilizer and water management, timely and timely spray fertilizer outside the roots to regulate the vegetative and reproductive growth relationship. It not only guarantees the healthy growth of the watermelon, but also has enough leaf area. It can also sit on the melon in a timely manner, and the nutrient input center can be transferred to the young melon in a timely manner to promote the expansion of the melon and improve the quality. 5. Increase the application of carbon dioxide gas fertilizer to provide raw materials for photosynthesis at a super level, improve the photosynthetic efficiency, and increase the production of watermelon organic nutrition. 6. Do a good job of artificial pollination and inserting tags to ensure that the melons are seated in time and suitable for picking melons. 7. Do a good job of comprehensive prevention and control of plant diseases and insect pests, minimize the occurrence of various plant diseases and insect pests, and ensure that the plants can grow and develop normally and flower and form melons.
