Abstract
The invention discloses a hydroponic breeding method of konjac minitype seed-tubers, and belongs to the technical field of agricultural breeding and propagation. The method is characterized in that petioles and basilar tumor-like callus tissue of non-rooted konjac tissue culture seedlings with a height of 4-5 cm are separated by using a knife, the tissue culture seedlings are washed with water, and then the base of the tissue culture seedlings is covered with a sponge; the tissue culture seedlings are implanted into a hole tray for indoor hydroponics by using tap water, and the tissue cultureseedlings are sprayed with a nutrient solution with a mass ratio of N to P to K to Ca to Mg being 23:1:21:4:1 and a total concentration of 225 mg / L every 7 days after growing for 7 days, wherein the nighttime indoor temperature is 10-15 DEG C, the daytime temperature is 20-25 DEG C, and the light is scattered light; and hydroponics is no longer carried out after 3 months of hydroponics, and the plants are allowed to do sprout tumble naturally, so as to harvest ripe konjac minitype seed-tubers. According to the method, konjac minitype seed-tubers with an average weight of 1.5 grams can be bredin three months, so that breeding cycle of konjac high-quality seed-tubers is greatly shortened, production cost is low, and survival rate or seed-tuber set rate reaches 85%-90%.
