Abstract:
OBJECTIVEThe experiment was conducted to study the dynamic growth rhythm of Achyranthes bidentata under different densities.
METHODThe plant samples were collected to measure the growth rate of each organ.
RESULTUnder different densities, the growing dynamic rhythm of A. bidentata were similar. The growth of main root exhibited a trend of "slow-fast-slow" by stages. The increase of dry root weight was fastest during the period of 30-40 days before harvest. The dry-matter increasing rate of whole plant was fastest in the later period of branching stage. The differences of root yields among the plants growing under different densities were significant.
CONCLUSIONFor high yield and good quality, the density of planting of A. bidentata should be considered.
