Efficient konjac seed ball cutting propagation method

Abstract

The invention discloses an efficient konjac seed ball cutting propagation method, and belongs to the technical field of konjac planting. The method comprises the steps that a strong konjac bulb of theweight being 1 kg or above is selected as a seed corm for cutting propagation; the seed corm is dried under the sun for 1-3 days, then an agricultural streptomycin solution is sprayed to a main bud and the bulb of the seed corm, and then drying is conducted; the dried seed corm is placed in a ventilated and dry room one month before konjac is planted for germination acceleration until the konjacbud grows to 0.4-0.6 cm; a sterilized cutter is adopted for horizontally and longitudinally cutting the seed corm subjected to germination acceleration around the circle of a konjac bud pit, and the konjac seed ball is cut into pieces; the konjac seed ball pieces are soaked in a talcum powder-agricultural streptomycin-thiophanate methyl mixed solution to make a cut opening uniformly covered with the solution, but the bud pit is not stained with the talcum powder-agricultural streptomycin-thiophanate methyl mixed solution, and then the konjac seed ball pieces are dried in a dry and ventilated environment for 13-16 days; the dried konjac seed ball piece are planted in the ground, and konjac land preparation, fertilization, planting and field management are conducted according to the conventional method.

Description

technical field [0001] The invention relates to a high-efficiency konjac bulb cutting propagation method, which belongs to the technical field of konjac planting. Background technique [0002] Konjac ( Amorphophallus Blume ), is a perennial herbaceous plant of the genus Konjac in the family Araceae. Konjac bulbs contain a large amount of glucomannan (KGM), which is not only widely used in the food industry as a food additive, but also in agriculture, medicine, chemical industry and other industries. At present, the market demand for konjac has increased significantly, and the supply of konjac bulbs has been in short supply for many years. In recent years, the planting area of ​​konjac has increased year by year, and there is a tendency to continue to expand. There is a huge demand for konjac seed for propagation. In the production process of konjac seed taro, the propagation method of corm cutting is also commonly used, but the wound of konjac corm is larger after cutting...

AI Technical Summary

Problems solved by technology

In the production process of konjac seed taro, the propagation method of corm cutting is also commonly used, but the wound of konjac corm is larger after cutting, and it takes a long time for the wound to heal, which greatly increases the infection of soft rot bacteria probability, seriously affecting reproductive efficiency

In the prior art, plant ash is used to cover the wound, but there is still a susceptibility rate of nearly 30% in plant ash coverage, and it is urgent to find a more effective breeding method
