Method for breeding seed konjac from konjac corms through segmenting with lateral bud

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 [0001] The invention relates to a method for breeding crops, in particular to a method for breeding seed taro by dividing the konjac corm into pieces and cutting into pieces. 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 an...

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

[0007] 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. 01131202.5 announced "A Method for Industrialized Rapid Propagation of Konjac", which is to change the natural growth cycle of konjac rhizome expansion through heat stimulation on the basis of tissue culture seedlings, and the matching growth and cultivation technology realizes the artificial rapid growth of previous generations. Propagation, this method still can only obtain the miniature taro seed below 60g through several generations of propagation, can't meet the needs of producing commercial konjac quickly; The effect is to create pollination opportunities to obtain a large number of low-cost konjac seeds, but it still takes 2-3 years for the konjac seeds to be cultivated into seed taro, which still cannot meet the needs of quickly producing commercial taro

In addition, there are many places in the folk that adopt the method of budding and cutting into pieces to breed taro, but the operation is generally simple, and no attention is paid to disinfection, cutting method, cutting size, germination and cultivation methods, resulting in low survival rate and affecting economic benefits.
