Problems solved by technology

At present, konjac seed taro comes from asexual propagation method, that is, after planting konjac and harvesting commercial taro, there are still a few (generally within 10) rhizomes for taro seeding, and the propagation coefficient is too low
Under natural circumstances, the parents of konjac sexual reproduction all need 3-4 years of early vegetative growth and cultivation to have inflorescences, and it is possible to flower

Embodiment 1

[0009] Take 20 4-year-old konjac seed taros with flower buds and store them in an 8°C freezer in early March, and plant them in mid-May as male parents; ) after soaking for 3 hours, planted as the female parent; from the first ten days of June, the male parent produced a large amount of pollen, and obtained a large number of sexual seeds through artificial pollination.

Embodiment 2

[0011] Take 30 3-year-old konjac seed taros with flower buds and store them in a 5°C freezer in early March, and plant them in mid-May as male parents; ) after soaking for 2 hours, planted as the female parent; from the first ten days of June, the male parent produced a large amount of pollen, pollinated by insects, and obtained a large number of sexual seeds.

Embodiment 3

[0013] Take 40 4-year-old konjac seedlings with flower buds and store them in a 15°C freezer in early March, and plant them in mid-May as male parents; soak 15,000 kg of rhizomes with 1,000 mg / L gibberellin (GA3) in April After 0.5 hours, plant as the female parent; from the first ten days of June, the male parent produces a large amount of pollen, and obtains a large amount of sexual seeds through artificial pollination.

Abstract

The invention provides a rapid reproduction method of konjac. In the method, rhizome without flower buds in those years or annual-triennial konjac is induced for flowering by induction of gibberellin (GA3) on the flower buds of the konjac, thus lowering cost of obtaining female parent; and meanwhile the flowering season of male parent is regulated and controlled to meet the flowering season of the induced female parent for creating the chance of pollination by inhibition of low temperature on growth of the flower buds of the konjac. Compared with a natural condition, the method can help rapidly increase the female parent material in quantity with low cost; the male parent can be successively cultivated after low-temperature storage, thus ensuring that the male parent meets the flowering season of the induced female parent; and a great quantity of low-cost konjac seeds can be obtained by hybridization of a small amount of the male parent and a great amount of the induced female parent.

Description

Technical field [0001] The present invention involves the field of agricultural complexity technology, especially a fast way of konjac. Background technique [0002] Konjac is a special economic crop with high economic value. Konjac powder has been widely used in industries such as food, medicine, petroleum, chemical industry, and light textile.Bottleneck.In addition to the prone to soft rot disease in konjac, the lack of a large amount of taro in production is the root cause.At present, the konjac breed is derived from asexual species, that is, after planting konjac harvesting product taro, there are several (usually within 10) root stems for breeding taro, and the variety coefficient is too low.In natural circumstances, parents who have sex with sexual reproduction of konjac need to have 3-4 years of early nutrition growth and cultivation to have inflorescences, and they can also bloom and pollinate seeds. Although each ears have 50-300 seeds, it takes time because it takes tim...
