Description
Technical Field
The invention belongs to the field of plant cultivation, and particularly relates to a method for fast breeding improved varieties of konjak.
Background
Konjak (Konjac) belongs to the genus of the family of Araceae (Araceae) and Ammophagullus blume, which is a perennial herb. Is widely distributed in southwest mountain areas of China, and has long cultivation and utilization history. Konjak is the only higher plant in the plant world which can be used for synthesizing a large amount of glucomannan so far, and the glucomannan is the main storage substance of underground corms of konjak, is a high-molecular organic compound, and is widely applied in the fields of food, chemical industry, medical health care, environmental protection and the like due to the advantages of good gel solubility, gel property, thickening property, film forming property and the like. Therefore, konjak has extremely high development and utilization value.
There are 21 types of konjak in China, at least 13 types of konjak are peculiar to China, and the konjak is mainly distributed in hilly areas of mountain areas in south provinces. There are 15 kinds of Yunnan, 8 kinds of Guangdong, 6 kinds of Guangxi, 5 kinds of Taiwan, 4 kinds of Hunan, 3 kinds of Fujian, jiangxi and Sichuan, and 1-2 kinds of provinces such as Hubei, guizhou, zhejiang, anhui, jiangsu and the like. From the distribution range of seeds, the konjak is the main current cultivar in China. However, as the planting period of the konjak flower is prolonged, the cultivation area is enlarged, the soft rot hazard is more and more serious, the continuous cropping obstacle is serious, and finally the planting area is reduced sharply. Soft rot and continuous cropping obstacle are main factors for restricting healthy development of the konjak planting industry, and no method for effectively solving the two problems at home and abroad is available so far, and healthy seed konjak can only be cultivated from seed konjak propagation.
The propagation method of the konjak can be divided into sexual propagation and asexual propagation, and asexual propagation is adopted in the production practice at present. The vegetative propagation has the advantage of relatively stable inheritance of the trait, and can be realized by a root-stem propagation method (formed by germination of adventitious buds on konjak tubers, which is an extremely important propagation material in konjak production), a tuber-cutting propagation method (50-150 g of healthy bulbs per cut), a block-cutting propagation method (in order to reduce wounds as much as possible, each cut block weighs 150-250 g), a bud-dividing propagation method (the terminal buds are cut or destroyed before storage, lateral buds can be promoted to germinate in spring in the coming year, the buds are cut during planting, only one bud is reserved on one cut block), a tissue culture propagation method (seedling production is realized by using a tissue culture technology) and the like.
The above propagation method of the konjak has the advantages and disadvantages: if the seeds are propagated, tens to hundreds of seeds can be obtained at a time, the konjak flowers and seeds are generally planted for 4 to 5 years, the obtained seeds can be planted for 3 to 4 years to form commercial konjak, and the period is too long. The cutting propagation and bud propagation modes not only belong to the lagging propagation technology, but also cause infection of germs by the wound, thereby causing epidemic diseases; the propagation of the rhizomes or the small bulbs is the main propagation mode, but the traditional planting method adopts a mode of selecting big and small to propagate seed taros, generally 3-5 rhizomes or small seed taros are formed by one 3-4 years of seed taros, and the propagation speed is slower.
In addition to tissue culture propagation methods, other asexual propagation methods have the following characteristics: (1) low reproduction coefficient and long production period. The propagation coefficient of the konjak is low, the konjak can be propagated for only one season in 1 year, and the propagation coefficient is difficult to exceed 1:20 in 1 year. (2) the seed amount is large. Under the current high planting level, the weight gain of the konjak (in the commodity production stage) is approximately 1:4-1:6, if the cultivation target is 4 tons/667 square meters, 0.8-1 tons (large seed konjak, small seed konjak, large seed konjak) are planted, and the seed konjak size is required to be 0.25-0.5 kg. And because the production of commodity taro and seed taro are carried out in a crossing way, when the production of the flower-shaped taro is developed, the selling price of the flower-shaped taro is good after a certain year, and some taros sell the seed taro, so that the seed taro is insufficient in the coming year, the seed source is unstable, and the implementation of a planting plan is influenced. (3) disease weight. In the process of adopting the asexual propagation method, diseases are easy to occur, such as the failure of disease comprehensive control, the yield reduction and the seed-borne disease of the taro are caused, the seed-borne disease of the taro can influence the improved variety and the planting in the next year, the seed degeneration is caused, and the method is the most critical problem in the seed propagation and production of the konjak. And (4) the difficulty in transferring and storing the seed taros is high. Along with the development of the konjak planting industry, the seed quantity of konjak is greatly increased. The production needs are met by the transportation of the seed taros, and the seed taros are easy to damage in the transportation process, so that serious seed rot is caused. If a large amount of taros are not fully pre-stored or the storage conditions are improper, a large amount of rotten seeds can be caused. Based on the characteristics of asexual propagation, a sound fine variety breeding technology is necessary to be established to prevent variety deterioration.

Amorphophallus rivieri cut propagation growth characteristics and yield analysis [ J ]. Changjiang vegetables, 2018, (10): 66-69.). Whereas the 500g konjak block cutting propagation coefficient of the invention is as high as 20.
Although there is no report on the incidence of the cutting propagation in the literature, the cutting propagation technology is not applied to production, mainly because the incidence of diseases in the later period of the cutting propagation is high, because the main propagation path of the soft rot of konjak is a wound, and the cutting propagation wound is large. The invention has the advantages that the cut seedling rate reaches more than 95%, the incidence rate of soft rot of the konjak is controlled to be 10%, an effective method is provided for the fine seed breeding of the konjak, and the green and efficient production of the konjak is facilitated.

Note that: each treatment was 100 pieces of konjak, repeated three times; the letters of each index in the same treatment represent that the difference is not extremely significant (P > 0.01), and the letters represent that the difference is extremely significant (P < 0.01). From Table 1 we can see that the sprouting and dicing sequence has the greatest effect on the emergence of konjak, and the thiourea and brassinosteroids have a remarkable effect on sprouting. The wilt-rick, the phenylate-allo-thiamethoxam and the monopotassium phosphate have the functions of improving seedling emergence and effectively controlling diseases, and the three have synergistic effects, wherein the difference of the number of plants is very obvious; the number of the harvested plants is different due to the different numbers of the plants, and the later-period yield is extremely remarkable. The seed dressing agent is changed into carbendazim and pilycine, and the two agents have good effects on bacteria and fungi, but have poor effects in preventing and controlling konjak diseases.
