Greenhouse circular cultivation method for cedrela sinensis

Abstract

The invention discloses a greenhouse circular cultivation method for cedrela sinensis. The method comprises the following steps: culturing seedlings, selecting parcel of paddy field, applying special fertilizer for cedrela sinensis, preparing a greenhouse and equipping the greenhouse with automatic sprayers, roller shutters and supplementary lighting lamps; preparing a garden bed in the greenhouse; planting the cedrela sinensis seedlings at the end of November and planting and hole-sowing in the ratio of 150 plants / square meter; fully watering the root-fixing water and watering seedling-returning water for one time after the seventh day; after 17-day dormancy, carrying out sun-shading and adding a cotton quilt; increasing temperature, supplementing light, supplementing humidity and guaranteeing 7-hour light illumination each day; keeping the temperature at 15-30 DEG C; keeping 75% humidity; supplementing light at night and maintaining the temperature; after sprouting for 2-3 days, applying 0.5% of a leaf fertilizer; after sprouting for 3-4 days, applying 5ppm auxin; preventing and controlling plant diseases and insect pests; picking after sprouting for 9 days; ending the picking period, sawing the trunk, only maintaining 10-15 centimeters and maintaining 10 centimeter roots as the biennial cedrela sinensis for continuing the greenhouse cultivation; and leaving the planting hollow at this season as the seedling culture field in the next year. The cedrela sinensis cultivated according to the invention has the advantages of high growth speed, high yield and high quality; the speed of breeding new seedlings is high; the use ratio of land is high; the variety cannot degrade.
