Abstract
A method for breeding seed konjac from konjac corms through segmenting with a lateral bud is disclosed. The specific method and the benefits thereof are as follows: the terminal bud of each konjac corm before overwintering storage is removed so as to start and promote the physiological activity of lateral buds in the overwintering period; after overwintering, the konjac corm is segmented so that the dominant lateral buds of the corm are more obvious; after transverse cutting of the corm, the corm is vertically cut so that the upper half part of the corm is divided into four pieces, thereby ensuring that each piece is provided with the dominant lateral bud and also ensuring that the weight of each piece is between 50 g and 80 g; therefore, the expansion coefficient of each segment is increased when enough nutrients for survival are present; before seeding, dormancy breaking and germination acceleration are performed so as to germinate the segments in advance; as a result, the growth period is prolonged; in addition, diseased seeds can be discovered before seeding to avoid losses; an appropriate cultivation method is capable of accelerating the konjac to sprout and come up out of the ground as soon as possible; a konjac dedicated callusing chemical and a seed konjac dedicated segmenting cutter are used, thereby avoiding wound infection; and a systematic breeding method through segmenting with the lateral bud is capable of increasing the survival rate and the expansion coefficient and improving the economic benefit.
Description
Technical field
The present invention relates to the mating system of a kind of crops, particularly a kind of konjak corm divides the lateral bud stripping and slicing to breed the method for kind of taro.
Background technology
Konjaku other Ming Amorphophalus rivieri belongs to the perennial perennial root stem tuber of Araeceae herbaceous plant; Mainly originate in the torrid zone, the Eastern Hemisphere, subtropics, China is one of original producton location, and all there is distribution in province mountain areas such as Sichuan, Hubei, Hunan, Yunnan, Guizhou, Shaanxi, Guangdong, Guangxi, Anhui, Fujian, Taiwan; Amorphophallus species is a lot, and there is more than 260 kind in the whole world, in state-owned 21 kinds, wherein 8 kinds be China peculiar.
China is shown in " Mingyi Bielu " of Wei Jin Tao Hongjing in period the earliest about the applicating history of konjaku, and first year konjaku is as medicine, later successive dynasties doctor work is all compiled, and Compendium of Material Medica has been introduced konjaku in detail as the instructions of taking of Chinese medicine and processing, modulator approach.
Konjaku is useful basic food, and to the too much people of edible animal property acid food, konjaku is eaten in collocation, can reach food acid, soda balance, and is favourable to health; At present health care, the medical function of konjaku many clinical experimental studies have been made all over the world; The conclusion basically identical; Wherein the main component konjaku glucomannan belongs to water-soluble hemicellulose, and its outstanding alimentary health-care function is to bring into play the regulating action of dietary fiber to nutritional imbalance, contained non-water-soluble fiber in the greengroceries such as it and Chinese cabbage, celery; Original shape discharge person is different after getting into human body, and it can participate in the metabolism of human body and influence intestinal changing to helping healthy direction; Konjaku is except that containing a large amount of Glucomannans; The amino acid and 10 kinds of mineral trace elements and the abundant food fiber that also contain alkaloid, pectin, 17 kinds of needed by human body; It is the unique plant that contains a large amount of Glucomannans of biosphere; Modern rich man's diseases such as high fat of blood, high cholesterol, diabetes, adiposis, constipation are had good preventive and therapeutic effect, are the desirable healthy food of the elderly, receive the favor of world's health food market deeply; In Japan, konjaku becomes the indispensable delicacies of seat seat already, is described as " magic power food ".
Konjaku glucomannan also has performances such as thickening, emulsification, gelling, bonding, water conservation; Its powder promptly can be used as major ingredient and makes various food; Also can be used as food additives to improve the quality of other food; In food industry, be used as food additives such as thickener, suspension emulsion, emulsifier, stabilizing agent, quality improver, be widely used in cereal product, meat products, beverage, flavouring, the bean product; Also can be used for fields such as cosmetics, textile industry, building industry, edible film, environmental protection, historical relic's protection in addition.
Owing to the extensive use of konjaku and all over the world to the understanding of konjaku, make that the market demand of konjaku is increasing, formed three big markets such as Japanese market, Korea S and market, Southeast Asia, American-European market at present.Needed both at home and abroad 900,000 tons of fresh Amorphophallus rivieris in 2006, and only 520,000 tons of output can't be satisfied the demand far away.
Since the eighties in 20th century, Chinese konjaku has begun industrialized development, but because of starting to walk evening; Planting technology is quantum jump very never, particularly breeding aspect the konjaku kind taro, exists a lot of not enough; Because konjaku is a perennial plant, seed will pass through 2-3 and cultivate, and could come manufacturer's article taro as kind of a taro; In order to accelerate the speed of production of konjaku, people have thought a lot of ways, and now popular is root-like stock mating system, tubercle propagation method and stripping and slicing propagation method etc.; These methods are compared with seed growing, have accelerated the speed of breeding greatly, but still a lot of not enough.The patent No. 01131202.5 has been announced " method of the quick culturing Amorphophallus rivieri of a kind of batch production "; This method is on the basis of tissue cultivating seedling, to change the self-sow cycle that the konjaku rhizome expands through thermostimulation; Supporting grown cultures technology realizes the artificial breeding fast of earlier generations; This method still can only obtain the miniature taro kind below the 60g through the several generations breeding, can't satisfy the needs that go out the commodity konjaku fast; Number of patent application 201010271821.0 has been announced a kind of konjaku quick-breeding method; Utilize the inducing action of gibberellin to the konjaku bud; Create pollination machine and can obtain in a large number konjaku seed cheaply; But the konjaku of seminal propagation still needs 2-3 could train the improved variety taro, still can't satisfy the needs that go out the commodity taro fast.In addition, among the people also have a lot of local methods that adopt the budding stripping and slicing to breed kind of taro, but generally all simple to operate, do not note sterilization, block cutting method, stripping and slicing size and vernalization and cultivation method, causes survival rate not high, influences economic benefit.
