The soil type is red-yellow soil or mountain-sand sandy loam, the organic matter content is ≥2.2%, and the soil pH is 5.5 to 6.5. (2) Seedling breeding. Choose a line with early fruit set, high fruit rate, large fruit, multiple seeds, heavy weight, good quality and resistance to pests and diseases. Fully mature, disease-free seeds are selected for breeding, and the roots planted in the field are propagated. (3) Cultivation management. 1. Field planting technology: The soil is thawed until the roots are planted before germination, and the roots without pests and diseases are selected and disinfected before planting. Planting density: 50 to 60 plants are planted per 666.7 m2 (mu) in Daejeon production. Generally, after three years, shed rotation is carried out, and roots are excavated and replanted once. 2. Introduction and pruning: After emergence, each plant leaves 1 to 2 strong buds as the main stem, removing excess buds and lateral buds at the base of the main stem. When the main stem grows to 1.5 m, the core is picked up in time, leaving 3 to 4 branches. At the beginning of the bud period, the core is extracted to promote the development of the flower buds, and the fruit setting rate is increased. During the fruit expansion period, the side branches of the fruit node and the long branches of the fruitless fruit are cut. 3. Male plants and pollination: Male plants are planted on the side of the planting wheel, and the growth is controlled by multi-vine pruning without fertilization. The growth height is controlled within 2m. It is usually a natural pollination, or it can be artificially pollinated by spraying the mist at 6 am to 7 am. 4. Fertilizer use: (1) Base fertilizer: Apply the base fertilizer to the opened colonization hole in the first half of the month.
