Method for rapidly breeding improved variety of amorphophallus konjac

Abstract

The invention belongs to the field of plant cultivation, and particularly discloses a method for rapidly breeding an improved variety of amorphophallus konjac. The method comprises the steps of careful selection of seed taros, seed taro drying in the sun, germination acceleration, dicing, seed dressing, sowing and the like. According to the method, the seedling emergence rate of dices reaches 95% or above and the morbidity of soft rot of the amorphophallus konjac is controlled to be 10% by soaking the seed taros with agents, preserving heat to accelerate germination, dressing the seed taros with agents, intensively managing the dices and controlling water, agents, temperature and humidity small environments, so that an effective method is provided for improved variety breeding of the amorphophallus konjac, and green and efficient production of the amorphophallus konjac is facilitated.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a method for rapid breeding of Amorphophallus konjac improved varieties. Background technique [0002] Konjac (Konjac) belongs to Araceae (Araceae) Konjac genus (Amrophophallus Blume), is a perennial herb. Widely distributed in the mountainous areas of Southwest China, it has a long history of cultivation and utilization. Konjac is the only higher plant found so far in the plant kingdom that can synthesize a large amount of glucomannan. Glucomannan is the main storage substance of konjac underground bulbs. It is a high-molecular organic compound. , Thickening, film-forming and other advantages are widely used in food, chemical, medical and health care, environmental protection and other fields. Therefore, konjac has extremely high development and utilization value. [0003] There are 21 species of konjac in our country, at least 13 of which are endemic to our count...

AI Technical Summary

Problems solved by technology

[0005] The above methods of Amorphophallus propagation have their own advantages and disadvantages: For example, although dozens to hundreds of seeds can be obtained at a time through seed propagation, Amorphophallus generally takes 4-5 years to bloom and set seeds, and the obtained seeds can only be planted in 3-4 years. Finished taro, the cycle is too long

(2) Use a large amount of seeds

In addition, because the production of commercial taro and seed taro is interleaved, when developing the production of flower konjac, it happened that the price of flower konjac was high in a certain year, and some taro farmers also sold the seed taro. Implementation of the planting plan

(3) serious disease

(4) It is difficult to transport and store taro species

It is necessary to transfer and transport taro to meet the production needs, and it is easy to cause bruises during the transportation process, causing serious rotten seeds

If a large number of yams are not fully pre-stored, or the storage conditions are not suitable, a large number of rotten seeds will also be caused.
