Description

A kind of efficient konjaku bulb rhizome cutting propagation method
Technical field
The present invention relates to a kind of efficient konjaku bulb rhizome cutting propagation methods, belong to konjaku planting technology field.
Background technique
Konjaku (Amorphophallus Blume), it is Araeceae Amorphophallus herbaceos perennial.In konjak corm Containing a large amount of glucomannans (KGM), serve not only as food additives and be widely used in food service industry, also agricultural, medicine, The industries such as chemical industry have wide application.Konjaku demand is significantly increased in existing market, and konjaku bulb is in that supply falls short of demand for many years Situation.In recent years, the cultivated area of konjaku increases year by year, and has the tendency that continuing amplification, and breeding is huge with konjac seed demand Greatly.In konjac seed production process, the modes of reproduction of bulb stripping and slicing is also more commonly used, but after konjak corm stripping and slicing wound compared with Greatly, it and needs a very long time wound that can heal, greatly increases the infection probability of soft rot bacterium, seriously affect Reproductive efficiency.Wound is covered using plant ash in the prior art, but there are still nearly 30% susceptible genes for plant ash covering, urgently Need to find a kind of more efficiently modes of reproduction.
Summary of the invention
The technical issues of for konjak corm rhizome cutting propagation method in the prior art, the present invention provides a kind of efficient konjaku Bulb rhizome cutting propagation method, the present invention pass through the processing to ganoid konjaku taro bulb stripping and slicing, it can be ensured that konjak corm incisional wounds are quick Dry, healing, reduces the germ infection probability of bulb after stripping and slicing, improves konjak corm breeding coefficient.
A kind of efficient konjaku bulb rhizome cutting propagation method, the specific steps are as follows:
(1) ganoid konjaku taro of healthy and strong konjak corm of the weight not less than 1kg as rhizome cutting propagation is chosen;
(2) ganoid konjaku taro of step (1) is placed in 1 ~ 3d of sunning under sunlight, then ganoid konjaku taro main bud and ball is sprayed using agricultural streptomycin solution Then stem dries processing;
(3) 1 month before konjaku is sowed, the ganoid konjaku taro that step (2) dries processing is placed in the indoor carry out vernalization of aeration-drying extremely Konjaku bud is 0.4 ~ 0.6 cm;
(4) using the cutter sterilized to carry out the ganoid konjaku taro that step (3) vernalization is handled, vertically and horizontally stripping and slicing obtains around konjaku bud nest circle Konjaku bulb stripping and slicing;
(5) the konjaku bulb stripping and slicing of step (4) is immersed in talcum powder-agricultural streptomycin-thiophanate methyl mixed solution makes Notch is uniformly stained with but bud nest does not speckle with talcum powder-agricultural streptomycin-thiophanate methyl mixed solution, is subsequently placed in dry and ventilated Dry in the shade 13 ~ 16d of processing in environment;
(6) the dry in the shade konjaku bulb stripping and slicing of processing of step (5) plant lowerly, conventionally carry out konjaku site preparation, Fertilising, plantation and field management.
Healthy and strong konjak corm is normally to fall the healthy bulb excavated after section in end of the year current year in the step (1).
The shape of the health bulb is that subsphaeroidal and bulb bud nest is big, terminal bud is sturdy, and bulb is intact to hurt, is disease-free Evil and mildew;
The concentration of step (2) the agricultural streptomycin solution is 100 ~ 150ppm;
Step (3) germination temperature is 13 ~ 20 DEG C;
The quality of konjaku bulb stripping and slicing is not less than 150 g in the step (4);
Contain bud nest tissue in step (4) the konjaku bulb stripping and slicing;
The mass ratio of talcum powder powder and water is in step (5) talcum powder-agricultural streptomycin-thiophanate methyl mixed solution 1:(0.6 ~ 0.8), the concentration of agricultural streptomycin is 100 ~ 150ppm, the methyl support that the concentration of thiophanate methyl is 800 ~ 1000 times Cloth saliva solution.
Beneficial effects of the present invention:
(1) konjaku bulb stripping and slicing is immersed in the talcum powder mixed liquor containing fungicide by the present invention, and notch is made uniformly to be stained with cunning Mountain flour mixed liquor, notch can rapid draing, the effect of accelerating wound healing, all standing of notch in addition is effective to completely cut off The unfavorable factor of external environment greatly reduces the infection probability of stripping and slicing notch germ;
(2) present invention adds agricultural streptomycin solution and thiophanate methyl in talcum powder solution, can effectively inhibit konjaku stripping and slicing By the harm of bacterium and fungi;
(3) the method for the present invention is simple and efficient, and is suitable for konjaku bulb the factorial production and common peasant household produces.
Specific embodiment
Invention is further described in detail With reference to embodiment, but protection scope of the present invention and unlimited In the content.
