FIELD: agriculture, in particular, plant root investigation devices. SUBSTANCE: apparatus has horizontal frame with poles fixed on straight and acute corners. Crossing bushings are secured on poles in equally spaced relation. Poles are provided with openings. Apparatus has flat forks defined by spokes. Plank is connected with hypotenuse part of frame through pivot joint. Poles are mounted in L-shaped channel adjacent to roots. Plant stem is retained between frame hypotenuse part and plank. Forks are positioned with their one outer spoke in bushing and with their other outer spoke - in opening so that they penetrate through plant rootage. EFFECT: increased efficiency and provision for determining rootage elements coordinates under laboratory conditions. 3 cl, 2 dwg |
