Bark-utilized planting material and production thereof

Abstract

Abstract PURPOSE:To obtain the title material easy to control water retentivity, resistant to disease and insect pest, excellent in durability and stability, thus suitable as a horticultural medium material by grinding chips of rot-resistant barks followed by impregnation with a liquid fertilizer. CONSTITUTION:Continuous barks peeled off raw wood such as Japanese cedar are chopped by a crusher and the resultant chopped barks are sprayed with water using e.g., a sprinkler to bring the water content of said barks to 50wt.%. Thence, the resulting product is subjected to e.g., a hammer crusher into fine pieces pref. 5-50mm long and 0.01-5.0mm thick, which are then dipped into a liquid fertilizer tank for e.g., 1-3 days followed by hydro-extraction, thus obtaining the objective material.
