Problems solved by technology

2. Lack of disease-resistant varieties
The species of Amorphophallus konjac planted by the local owner is seriously degraded, with poor disease resistance and low yield
3. Insufficient provenance and low breeding coefficient of taro
In the southern Shaanxi area, a large number of seeds need to be transferred from other places every year, which seriously affects the quality of the seeds themselves and increases the input of

Embodiment 1

[0036] A method for promoting the germination of konjac latent buds to rapidly produce seed taro, comprising the following steps:

[0037] Step 1, screening of bulbs

[0038] Screen out the seed bulbs with a quality of 60-150g for subsequent use;

[0039] Step 2, seed bulb processing

[0040] Select sunny days for treatment at the end of September after the bulbs are harvested.

[0041] (1) Terminal bud treatment: wash and dry the bulbs, and then use a small iron spoon to dig out the entire terminal bud along the direction of the terminal bud nest. The depth of digging is 0.2-0.3cm; Potassium acid solution to disinfect the small iron spoon, soak and disinfect once every time you dig, soak for 20s.

[0042] (2) All the axillary buds inside the terminal bud nest and along the direction parallel to the top of the bud nest are removed, subject to the absence of axillary buds, that is, the thickness of the cut is 0.1-0.2 cm, and the stems at the bottom are collected for subseque...

Embodiment 2

[0059] A method for promoting the germination of konjac latent buds to rapidly produce seed taro, comprising the following steps:

[0060] Step 1, screening of bulbs

[0061] Screen out the seed bulbs with a quality of 150-250g for subsequent use;

[0062] Step 2, seed bulb processing

[0063] Select sunny days for treatment in early October after the bulbs are harvested.

[0064] (1) Terminal bud treatment: wash and dry the bulbs, and then use a small iron spoon to dig out the entire terminal bud along the direction of the terminal bud bud nest. The depth of digging is 0.3-0.5cm; Potassium acid solution to disinfect the small iron spoon, soak and disinfect once every time you dig, soak for 20s.

[0065] (2) Divide the corm into two along the direction parallel to the bottom of the terminal bud nest. The specific cross-cutting position is based on the bud scar at the base of the terminal bud on the cut surface of the lower part of the corm. The average thickness of the cut ...

Embodiment 3

[0081] A method for promoting the germination of konjac latent buds to quickly produce seed taro is basically the same as the method of embodiment 1, the difference is that in step 3 (1), the ridge width is 1.5m, the furrow width is 1m, the row spacing is 45cm, and the plant spacing is 30cm;

[0082] Bioreactor preparation: waste mushroom residue left after harvesting shiitake mushrooms + EM bacteria and Bacillus subtilis used in production are mixed at a mass ratio of 1:1 + crushed to 2-3cm dead leaves;

[0083] The specific stacking method of the bioreactor: apply hole application between the two rows of konjac in each ridge. The depth of the hole is consistent with the sowing depth of konjac. The average hole depth is 20cm, and the hole diameter is 15-17cm; Leaves, the mass ratio of the two is 2:1, followed by spraying the compounded bacterial agent suspension, the total concentration of bacteria is ≥10 6 cfu / mL, until the discarded fungus residue is wet; finally, cover wit...

Abstract

The invention belongs to the technical field of biology, and particularly relates to a method for promoting sprouting of resting buds of konjac to fast produce taros. The method mainly comprises the steps of screening of seed corms according to the size specifications, treatment of the seed corms, treatment with different concentrations of hormones, treatment with a section healing agent, selection of the winter sowing time and land parcels, plastic film mulching in cooperation with biological reaction stacks, and the like. By means of the production method, a reproduction rate of the konjac taros reaches 16-22, a disease incidence is relatively reduced by 27% or above, the emergence stage and the full seedling stage are advanced by 41 days or more and 48 days or more respectively, an emergence rate reaches 96% or above, and the production and planting costs are effectively saved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for promoting the germination of konjac latent buds and rapidly producing seed taro. Background technique [0002] Konjac is a perennial herbaceous plant belonging to Araceae Konjac. It contains a large amount of soluble dietary fiber-glucomannan, which is the seventh largest nutrient for the human body. One of the characteristic industries of "X", which plays an important role in the economic development of southern Shaanxi, poverty alleviation, rural revitalization and ecological protection, and is also the most promising industry in our province to become the world's number one. [0003] However, with the continuous expansion of the planting area, some bottleneck problems have also appeared, resulting in a decrease in the planting area year by year and a decrease in output, which seriously restricts the development of the konjac industry. The specific manifes...
