Problems solved by technology

[0002] Konjac corm contains high organic glucomannan, which is a kind of soluble semi-fiber, has the properties of gelation and gelation, and can be used in food industry, chemical industry, pharmaceutical industry, agriculture, environmental protection and other fields. With the development of konjac The value of the product is increasingly valued by the market. At present, konjac planting has been carried out on a large scale in the Yangtze River Basin. However, due to the low natural reproduction coefficient of konjac, it takes four to five years to form a commodity, and it is difficult to form an industrial scale.
In recent years, some people have begun to explore the use of tissue culture technology to obtain a large number of high-quality seedlings, but how to shorten the natural growth cycle of annual konjac rhizome expansion has not yet achieved substantial progress

Embodiment 11

[0008] Embodiment 11), transplanting of tissue culture seedlings: the culture medium on the konjac tissue culture seedlings is washed clean with clear water, transplants in the vermiculite seedling tray that is housed in disinfection, covers the film insulation 10 days; Then uncovers the film survival rate 98%. % or more; 2), strong seedling cultivation: place the tissue cultured seedlings at a temperature of 20-25°C, a humidity of 70-80%, and a light of 1000-1500LUX to cultivate the seedlings for 20-25 days and enter the head replacement stage; 3), miniature Fast-growing taro cultivation: In a suitable environment, the tubers expand rapidly after changing heads. Increasing the amount of nutrients applied to the substrate is an important measure for fast-growing cultivation. The nutrient solution is sprayed once a week. The nutrient solution contains the following active ingredients: N:P : K: Ca: Mg: B: Fe = 250: 200: 300: 60: 10: 4: 2: 8 mg / L. The fertilization cycle lasts fo...

Embodiment 21

[0009] Embodiment 21), rooting bud transplanting, the rooting bud of tissue culture is grown to be 0.5-1 centimeter konjac and transplanted in the sterilized vermiculite, the sterilized vermiculite of 3-5 millimeter is covered on the bud point, humidity 90-100%, temperature 28-35°C, without light, without film covering. One week, the plant height of konjac seedlings is 3-4 cm, and the emergence rate is more than 90%; 2), the strong seedlings are cultivated, and the konjac seedlings are moved to a humidity of 70-80%, a temperature of 25-30 ° C, and a light of 1000-1500LUX conditions for 25- 40 days, enter the head-changing period; 3. The fast-growing cultivation of miniature taro, in a suitable environment, the tubers will expand rapidly after changing the head, and the total increase in the amount of nutrients applied to the substrate is an important measure for fast-growing cultivation. Spray the nutrient solution once a week : The nutrient solution contains active ingredient...

Abstract

The present invention provides an industrial quick propagation method of konjak, and is characterized by that on the basis of group-cultivating seedling thermal stimulation is used to change natural growth period of konjak rhizome intumescence, and matches it with growth cultivation technology to implement ortificial quick propagation of first several generations of konjak. The industrial quick propagation method of konjak includes the following steps: cultivating konjak implementing one generation intumescence period and making thermal stimulation at 40-45 deg.c to force senility treatment, then implement next generation intumescence period under the condition of normal culture. As compared with existent planting technology of konjak it possess the following advantages: 1. test tube seedling transplating, can reduce cost by three times; 2. utilizing greenhouse, and can produce miniature konjak the same year; 3. shortening production period, can implement 2-3 generation intumescence, can obtain 30-60 g miniature konjak by cultivating 3-5g miniature konjak, the same year.

Description

technical field [0001] The invention relates to a method for industrialized rapid propagation of konjac, which belongs to the technical field of plant cultivation methods, and is especially suitable for industrialized rapid propagation of the first, second and third generations of konjac. Background technique [0002] Konjac corm contains high organic glucomannan, which is a kind of soluble semi-fiber, has the properties of gelation and gelation, and can be used in food industry, chemical industry, pharmaceutical industry, agriculture, environmental protection and other fields. With the development of konjac The value of the product is increasingly valued by the market. At present, konjac planting has been carried out on a large scale in the Yangtze River Basin. However, due to the low natural reproduction coefficient of konjac, it takes four to five years to form a commodity, and it is difficult to form an industrial scale.
