1. Method of cultivation and seedling raising in the facility (1) Night cool seedling is a method of raising seedlings of strawberry seedlings with low temperature and short daylight. Strawberry seedlings were treated for 20 days at 141°C and daylight for about 8 hours/day. The treatment usually starts in mid-July and the fruit matures from late October to early November. (2) Low-temperature dark seedling is a method of raising seedlings of strawberry seedlings by using cold storage at low temperatures and dark conditions. The strawberries were treated at 141°C and 90% humidity for 15 days. The cost is lower than the night cold nursery. Treatment begins in mid-August and begins in early November. (3) High-cold seedling is a method to promote the flowering of strawberry seedlings by moving flat seedlings to cool, high-altitude mountains in summer. In mid-September, flower bud differentiation was the target, and in mid-August, the mountain will be harvested in late November. (4) Nutrient seedlings The flower buds were induced by controlling the nitrogen nutrition status of the plants. Generally in mid-September, flower buds differentiated and harvested in late November, harvesting about 10 days earlier than nursery seedlings. In recent years, labor forces have been invented in various producing areas, such as the "Elevated Nutrient Ravioli Seedling Raising Act" and the "Three-Dimensional Shelf Rafting". 2 Facilities cultivation techniques (1) Selection of shallow dormant early maturing varieties such as Fengxiang, female peaks, earth girls, Xingxiang, Zhang Ji and Li Hong etc. (2) Preparation before planting 1 Soil disinfection The greenhouse is closed, the soil surface Cover with old agricultural film compaction. The use of solar heat disinfection, or disinfection with drugs. 2Ploughing and fertilization combined with deep ploughing, applied ripe compost (1t/667m2), reuse of basal fertilizer, and long-acting fertilizer accounted for more than 50%. (3) Plant colonization immediately after the formation of flower buds. The spacing between rows is 25 to 35cm and 20 to 25cm. After planting, water should be fully watered according to the principle of a few times, and slowly reduce the number of watering after survival. (4) The mulching film covers the mulching film. (5) When Gibberellin is about to bud, spray 5~10mg/l gibberellin, spray 10ml per plant. (6) Insulation Axillary buds are differentiated and then heated by a heater and cooled by a ventilation fan. The room temperature is controlled at 25-28°C during the day and 7-10°C at night. In the early stage of warming, the humidity in the greenhouse is high, which can easily cause gray mold, powdery mildew, etc., and reduce humidity through ventilation. The ground temperature is increased by the use of electric heating lines (positioned before the mulching film) to heat or circulating water pipes (embedded at the time of boring) to transport hot water. (7) Electric lighting In order to maintain the stance, use the electric lamp to extend the lighting method. The incandescent lamp is generally 4kw per 667m2. There are two ways to extend the light: one is to continuously light for 2 to 3 hours after dark, and the other is to light 10 to 15 minutes per hour after dark until dawn. (8) The application of co2 during daytime application of co2, co2 concentration: from late November to the end of February, 0.075%; in March, 0.05%; after April, 0.03%. (9) Stocking bees to promote pollination and fertilization The beehives are moved into the greenhouse 8 days before flowering, and they are moved out 30 days before harvest. Each 667m2 stocking bees 1 to 2 groups. (10) Top dressing and plant rearrangement depend on the variety and tree vigor. (11) harvesting and storage appropriate picking, picking into the cold storage until the market, cold storage temperature 2 ~ 5 °C. Recently some of the production areas in the cold storage plus ozone generator sterilization and preservation, the effect is good. In Japan, strawberry cultivation facilities are generally produced by labor-saving methods, and their common features are elevated; they are cultivated with substrates (peat, compost, etc.) or nutrient solution, and the “Pleasant Cultivation Greenhouse System†of Kagawa Prefecture is constructed with water pipes. About 1m gantry, the substrate is peat soil, electric lighting heating, drip irrigation, fertilization (via drip irrigation) and co2 application in the greenhouse are all regulated by the integrated environment automatic control system. Hand-work is mainly for picking leaves, fruit thinning and harvesting. 3 Open cultivation techniques Key points Before planting, combined with ploughing, the basal fertilization per 667m2 is about 2t, accounting for 75% of the amount of fertilizer. Cover film before late February. After the winter, ditch drainage, removal of old leaves, diseased leaves and excess axillary buds, control of gray mold, powdery mildew, aphids and leafhoppers. In late March, take a simple plastic shelter to cover the rain. During the flowering period, straw is planted in the garden to improve fruit quality. In the northeast of Japan, the climate is relatively cold, often using seedbed nursery, open cultivation, flower buds generally differentiate in the late one year in late September, due to delayed emergence, harvested and listed in the following year of June to August. At this time, it is a low season for strawberry harvesting in the southern producing areas. It not only extends the supply period of strawberries, satisfies the needs of consumers, but also has high economic benefits.
