in horticulture, the simplest type of structure for raising seedlings in sheltered ground. In the central region of the European USSR seedbeds are used for growing cold-resistant vegetables and other crops that are to be planted in the open ground between May 10 and June 10. After the seedlings are transplanted, the seedbeds are used for growing vegetables and flowers. Seedbeds measure 150 cm across and have plank sides. Seedbeds lack trenches (cold seedbed) or have a trench 30–40 cm deep (warm seedbed). Cold and heated beds are also used as seedbeds. On cold nights, seedbeds are covered with mats, bast, and other protective materials. Plants in beds are always kept under impermeable, transparent polymeric films.
