METHOD FOR RAISING YOUNG SEEDLING OF JAPANESE HORSERADISH AND APPARATUS FOR RAISING

摘要

PURPOSE: To mass-produce Japanese horseradishes of good quality for the full year by keeping the water temperature, quantity and quality of a culture water and a material, etc., of a culture medium in a state optimal for the raising of the Japanese radishes. ;CONSTITUTION: A frame for hanging each forward feeding tool for young seedlings set so as to successively extend a gap between the roots of the seedlings and culture water flowing down on a highly tilted water flowing panel 1, a medium tilted water flowing panel 2 and a low tilted water flowing panel 3 and the flowing culture water according to the growth of the seedlings is installed on both sides of an apparatus for raising and the forward feeding tool for the young seedlings is successively fed forward to a higher part. The water temperature of the culture water is kept at 12-15°C and the flow velocity thereof is kept at 20cm/see. The flow velocity is further increased according to the growth of the seedlings to always keep the water quality neutral. A culture medium internally filled in the forward feeding tool for the young seedlings is constructed from a composite material prepared by drying cellobiose or cellulose powder, an aqueous solution of chitosan and starch by heating and zeolite, vermiculite, etc.;COPYRIGHT: (C)1994,JPO
