A CULTIVATION SUBSTRATE UNIT FOR USE IN CULTIVATION OF PLANTS, PARTICULARLY FOREST PLANTS

摘要

Plants are grown in shaped suitable substrates 16 which rest on a support 10. Between the support 10 and the substrates 16 are provided two nets 17, 18. Periodically the roots are sheared either by moving the nets relative to one another, or by the action of a blade or wire 14 moving between the nets. This shearing aids growth since the removal of each root tip results in the growth of several root tips. IMAGE
