The invention discloses an
aquaculture seed
reproduction method for micro seed tubers of konjac, belonging to the technical field of
agriculture breeding and propagation. The
aquaculture seed
reproduction method comprises the steps of segmenting nodular calluses of a petiole and a base thereof of a konjac
tissue culture seedling by using a knife, wherein the konjac
tissue culture seedling grows until reaching the height of 4-5cm and does not root; washing the
tissue culture seedling with water and wrapping the basal of the tissue culture seedling with
sponge, planting in a hole plug and carrying out water-planting indoors by using
tap water, spraying a
nutrient solution once every 7 days after the tissue culture seedling grows for 7 days, wherein the
mass ratio of N to P to K to Ca to Mg in the
nutrient solution is 23:1:21:4:1, the total concentration of the
nutrient solution is 225mg / L, the indoor temperature at night is 10-15 DEG C, the indoor temperature in the
daylight is 20-25 DEG C, and the illumination is
scattered light; carrying out water-planting for 3 months and then stopping water-planting to ensure that plants naturally suffers from sprout tumble, namely, the mature micro seed tubers can be harvested. According to the method, the micro seed tubers with the weight of 1.5g on average of the konjac can be bred, thus the propagation period of excellent seed tubers of the konjac is greatly shortened, the production cost is low, and the
survival rate and the tuber yield reach 85-90 percent.
