A kind of method that improves the rate of asexual reproduction of konjac

Abstract

The invention provides a method for increasing the vegetative propagation rate of konjak. The method comprises the steps that firstly, 50-250 g konjak is selected as seed konjak; secondly, the seed konjak is soaked with a 1-naphthylacetic acid and 6-benzylaminopurine solution; thirdly, the soaked seed konjak is naturally dried in air and then wrapped with pentahapto disinfecting powder for disinfection; fourthly, storing is carried out, wherein a propagation material is stored at the room temperature in a temperature preservation mode; fifthly, ridging is carried out; sixthly, pentahapto disinfecting powder is evenly scattered and applied to ridges at the amount of 25 kg per mu before sowing and seeding for disinfection; seventhly, sowing is carried out in the period from the first ten days to the last ten days in April; eighthly, management is carried out, wherein weeding and disease prevention are carried out; ninthly, harvesting is carried out, wherein the seed konjak is dug out in the period from the last ten days in October to the middle ten days in November. By means of the method, the propagation coefficient is increased, and multiple pieces of konjak can be obtained through one seed. The method is easy and convenient to implement, high in adaptability and easy to apply and popularize in a large area.

Description

technical field [0001] The invention relates to a method for improving the asexual reproduction rate of konjac taro, which belongs to the technical field of agricultural cultivation and relates to the category of plant asexual reproduction. Background technique [0002] Konjac is a perennial herb of Araceae Konjac. Its various unique physical and chemical properties make it widely used and developed. It has expanded from a single food application to the fields of medicine, chemical industry, textile, printing and dyeing, and petroleum. Konjac has been The World Health Organization has identified it as one of the top ten health products, and has the reputation of "industrial monosodium glutamate" and "intestinal cleaner". It has wide uses, great development potential, and good market prospects. It is called a sunrise industry in the new century. [0003] At present, there are many methods of breeding konjac.

AI Technical Summary

Problems solved by technology

[0003] At present, there are many methods of breeding konjac. When sexual reproduction is adopted, the sexes of konjac are not ripe, and it is difficult to obtain propagation materials (hard seeds) in natural production methods; the tissue culture propagation method, due to high cost and large investment, is not suitable for taro. Farmers cannot pass it on; propagation by cutting into pieces can certainly increase the reproduction coefficient, but it is rarely used in production because it causes more wounds and is easy to cause diseases.

At present, most of the production uses asexual propagation methods such as bulblets and rhizomes for cultivation, but the propagation coefficient is low, and it is difficult to meet the demand for production seeds.

With the expansion of artificial cultivation and large-scale planting area, the shortage of provenance has become more apparent, and the number of planted taro is seriously insufficient, which has become a problem and bottle stem in konjac production, restricting the stable and healthy development of the entire konjac industry

[0004] The propagation coefficient of konjac is low, and the amount of species used is large. The existing traditional propagation methods can no longer meet the needs of production. Therefore, it is imperative to explore new and applicable propagation methods
