Title: Cultivation method for plants and device for the same
Inventor: KUDO FUMIO
IPC: A01G31/02
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a cultivation method drastically reducing the use of Sphagnum palustre, reducing the cultivation cost, and capable of labor saving of the replanting work of plants such as orchids or the like. SOLUTION: Wood pieces 3 are obtained by forming woods such as a Japanese cypress, white cedar or the like into particles having 3 mm of diameter. A seedbed 4 is obtained by filling the wood piece 3 in s seedbed case 2. A seedling of the orchids 6 is planted to the seedbed 4 in a situation in which the root of the orchids 6 is wrapped with the Sphagnum palustre 5. Forming the seeded 4 utilizing the wood pieces 3 drastically reduces the consumption of the expensive Sphagnum palustre 5. The planting intervals of the orchids seedling are capable of extending because the area of the seedbed 4 is enlarged and the frequency of replanting work can be reduced.
