example 1

[0038] Konjac taro rapid propagation method:

[0039] The planting site of this example is located in Xiaobao Village, Xingshan Town, Majiang County, Guizhou Province, with an altitude of 1000-1100 meters. The area is 10 mu.

[0040] 1. Selection of taro

[0041] The kind of taro is selected from two-year-old konjac tubers with no damage, no mildew, no scar, flat mouth, small nest, thick terminal bud, smooth surface, spindle-shaped appearance, neat germ embryos, basically the same size, and a single mass of less than 150g. Bamboo baskets and plastic baskets should be used for transporting taro seeds, and soft bags and silk bags should not be used for transporting taro seeds.

[0042] 2. Seed treatment

[0043] Before cutting into pieces, pick out the taro and sun-dry the seeds for 1-2 days, soak the seeds with 10 million units of agricultural streptomycin 600--700 times solution for 1 hour, pick up and dry them for later use.

[0044] 3. Cutting method

Abstract

The invention provides a fast propagation method for seed konjak. According to the invention, corm and rhizome of konjak are distributed with a great number of latent buds; when the corm of the konjak is used as a seed, only terminal buds are germinated into seedlings, while one part of the latent buds are differentiated into a root system, and the other part of the latent buds are latent and do not germinate. The method provided by the invention stimulates the latent buds to germinate into seedlings mainly through stripping and slicing of the corm, matches with seedbed management measures like use of a cut healing agent, fine adjustment of physicochemical environment of soil, improvement of microbial communities and control of the occurrence of soft rot disease, improves an original propagation coefficient of 3 to 5 times to 15 to 20 times, realizes fast propagation of the seed konjak, and is applicable to industrial production.

Description

technical field [0001] The invention relates to a method for rapid propagation of konjac taro, which is suitable for factory production and belongs to the technical field of plant cultivation. Background technique [0002] Konjac mainly uses bulblets and rhizomes as propagation materials, and its propagation coefficient is low. During the breeding process, encountering high-temperature and high-humidity weather, soft rot and downy mildew often occur explosively, resulting in serious yield loss or even failure. Insufficient supply of improved varieties restricts the development of konjac industry. [0003] Konjac bulbs and rhizomes distribute many hidden buds. When konjac bulbs are used as seeds, only the top buds germinate into seedlings, and some of the other hidden buds differentiate into roots, and some are hidden. The method mainly cuts the corm into pieces, stimulates the germination of the hidden buds, increases the original 3-5 times the reproduction coefficient to ...
