Method for breeding commercial konjac by using terminal buds in konjac bud pits

Abstract

The invention discloses a method for breeding commercial konjac by using terminal buds in konjac bud pits. The method has the advantages that a knife special for digging the konjac bud pits can ensure that the dug bud pits have skin, pulp and terminal buds, the mass of each bud pit dice can also be ensured between 200 and 250 grams, and a callus agent special for konjac can be coated during digging to ensure that the bud pit dices can be prevented from being infected and improve the survival rate and the piece weight of the commercial konjac; and wound healing can be quickened by a proper soaking method, plant diseases and insect pests can be reduced by a proper sterilization method and a proper preservation method, and the expansion rate of the bud pit dices and the piece weight of the commercial konjac can be improved by a proper sowing method; and by a systemic method, the konjac seed source can be increased, the survival rate can be improved, and the yield can be improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, in particular to a method for propagating commercial taro with konjac bud nests and terminal buds. Background technique [0002] Konjac, also known as Konjac, belongs to the perennial tuber herbaceous plant of Araceae; it is mainly produced in the tropical and subtropical regions of the Eastern Hemisphere, and China is one of its origins. Sichuan, Hubei, Hunan, Yunnan, Guizhou, Shaanxi, Guangdong, Guangxi, Anhui, Fujian, Taiwan There are many kinds of konjac, there are more than 260 varieties in the world, and 21 kinds in China, 8 of which are endemic to China. [0003] The history of the application of konjac in our country was first seen in Tao Hongjing's "Famous Doctors" in the Wei and Jin Dynasties. Konjac was first recorded as a medicine, and later medical works of all dynasties were compiled. method. [0004] Konjac is a beneficial alkaline food. For people who eat too much anima...

AI Technical Summary

Problems solved by technology

In 2006, domestic and foreign demand for fresh konjac was 900,000 tons, while the output was only 520,000 tons, far from meeting the demand

However, there are still some problems in its specific operation method, such as fertilizing only the ditch bottom and cover fertilizer, which does not improve the overall fertility of the soil

[0008] Since the 1980s, Chinese konjac has started to develop industrially, but due to the late start, there has been no major breakthrough in planting technology, especially in the breeding of konjac seed, there are many deficiencies. Since konjac is a perennial plant, the seeds have to pass Only after 2-3 years of cultivation can it be used as a kind of taro to produce commercial taro. In order to speed up the production speed of konjac, people have thought of many ways. Now the more popular methods are rhizome propagation method, small tuber propagation method and cutting propagation method, etc. Compared with seed breeding, these methods have greatly accelerated the breeding speed, but there are still many shortcomings

Patent No. 200610010884.4 announced "a high-efficiency cultivation method for fine varieties of Yunnan plateau flower konjac", which adopted a set of effective measures to improve the yield and quality of konjac, but this method could not improve more provenance; patent application number 201010271821.0 has announced a kind of fast propagation method of konjac, utilizes gibberellin to the induction of konjac flower bud, creates pollination opportunity to obtain a large amount of low-cost konjac seeds, but the konjac of seed propagation still needs 2-3 years to be cultivated into kind of taro, Still can’t meet the needs of fast commercial taro; The growth and cultivation technology realizes the artificial rapid propagation of previous generations. This method can only obtain miniature taro seeds below 60g through several generations of propagation, which cannot meet the needs of rapid production of commercial konjac; The method of breeding commercial taro is generally simple to operate, and no attention is paid to disinfection, digging and cutting methods, size of digging pieces and cultivation methods, resulting in low survival rate and seriously affecting economic benefits
