Abstract:In order to confirm key parameters of best time and frequency and position of Zizania Caduciflora harvest management,the experiment was conducted in different months, different times and different positions over ground by outdoor and field simulation,to study the growth and physiological characters of Zizania Caduciflora regeneration rate and stem length and so on. August was better for regeneration of Zizania Caduciflora. In October, compared with August,regeneration rate was decrease 29.6%,the length and diameter of regeneration plant respectively decreased 26.9% and 25.9%. Repeat harvest had inhibiting effect to subject,compared with August and October single cutting,maximum regeneration ratio of repeated cutting for the same pieces of experiment quadrat had decrease 37.1% and10.6%.thus, harvest management should be based on single cutting. On the phytal zone (depth of water50cm), along with water level was better, the regeneration rate was 100%.
