NATURALLY SELECTING AND ABSORBING WATER CULTURE DEVICE OF PLANT NO.2

摘要

PURPOSE: To greatly grow the whole plants for a long period of time and to aim a distinguished increase in production of agricultural products by developing a method of water culture based on an utterly new general idea. ;CONSTITUTION: (a) Various nutritive elements required for plants are divided into two groups by a subsidiary culture tank 2, made into mist and supplied to plants at an early stage of planting. (b) A culture solution made into mist is diffused by wind pressure of a fan and rooting is quickened to serve respiration of roots. (c) Nutritive salts are divided into two groups and diluted to avoid deterioration of liquid manure composition caused by chemical reactions of the mutual salts. (d) A separator 3 is set to prevent coexistence of the salts, roots can be introduced by mist to both sides of the separator without depending upon a hand, labor is reduced in this method and rooting is also excellent. (e) A great number of independent liquid manure pots 4 are laid in each element at the bottom of a main culture tank 1 so that the whole elements can be freely selected in 'required amount in the case of necessity'.;COPYRIGHT: (C)1994,JPO&Japio
