Description
Technical Field
The invention relates to the technical field related to seed cultivation, in particular to a rapid breeding method for konjac seedling seeds.
Background
The seed of konjak is the sexual organ of konjak obtained by natural or artificial pollination after the konjak blooms. The growth process of the konjak seedling seeds is the process that the konjak seeds are dormant for a long time after being mature, germinate and emerge, and finally form small bulbs.
The propagation mode of konjak mainly adopts the bulb and the rhizome of konjak and other asexual propagation modes. The main problems are that the konjac adopts asexual propagation for a long time, the seed source is single, the disease of the progeny is easy to accumulate, the degeneration is very serious, and the yield and the quality of the konjac are directly influenced. The seed propagation of the konjak seedlings can not only give play to heterosis, enhance disease resistance and improve propagation coefficient, but also prevent the konjak seeds from degeneration, which is an effective way for solving the virus-free propagation of the konjak seeds. However, because the dormancy period of the konjak seedling seeds is long under natural conditions, the emergence rate is extremely low (the emergence rate of farmer sowing is lower than 30%), and the konjak seedling seeds are difficult to be directly applied in production. The invention utilizes modern facility gardening and soilless culture technology, and aims to increase the source of the konjac seeds, improve the emergence rate of the seedling seeds, accelerate the breeding process of the konjac seeds, enhance the resistance of the konjac seeds and further improve the yield and the quality of the konjac seeds.
For example: the application number CN201210364297.0, entitled "a method for rapidly propagating No. 1 Delhi seed taro" provides the steps of seedling seed cultivation, seed harvesting and preservation, seedling substrate preparation, plug seedling, field transplantation, field management, harvesting and storage, and the seed taro is rapidly propagated by utilizing No. 1 Delhi seed, the propagation multiple of the seed taro is up to 600 times, and is more than 150 times of that of conventional block-cutting propagation. The method solves the problems of low propagation coefficient, serious virus accumulation and fast degeneration of the seed konjac in the propagation of the seed konjac, and has the advantages of simple operation method, good seed konjac quality and low cost. The defect is that the breeding method belongs to the traditional seedling raising method and cannot ensure higher seedling rate. And (II) the sowing time is limited, and the method is similar to a field propagation method. And (III) breeding new taro seeds by using the seedling seeds can be omitted greatly due to small harvest of the taro seeds.
For another example, the application number is CN201310407197.6, the invention name is 'a water culture seed reproduction method of konjak micro seed taro', and the proposed method is that a non-rooted konjak tissue culture seedling with the height of 4-5cm is cut off by a knife from a leaf stem and a tumor-shaped callus of a base part of the seedling, the tissue culture seedling is washed by water and then wrapped by a sponge at the base part of the tissue culture seedling, the tissue culture seedling is planted in a plug tray and cultivated by tap water indoors in a water culture way, and N is sprayed every 7 days after the tissue culture seedling grows for 7 days: p: k: ca: the mass ratio of Mg is 23: 1: 21:4: 1, nutrient solution with the total concentration of 225mg/L, wherein the indoor night is 10-15 ℃, the daytime is 20-25 ℃, and the illumination is scattered light; after 3 months of water culture, water culture is not carried out any more, and the plants are naturally transplanted to obtain mature micro seed taro. The method can breed 1.5 g of micro seed konjac on average in three months, greatly shortens the propagation period of high-quality seed konjac, and has low production cost, survival rate and konjac bearing rate of 85-90%. The invention has the defects that the average 1.5 g of the konjak micro seed taro can be bred in three months in the method (I), but the period required by the early-stage tissue culture from callus to bud differentiation to the height of 4-5cm of seedlings is longer, generally 3-6 months (II) are required, only the water culture mode of tissue culture seedlings is mentioned, and the seed growing mode is not mentioned. And (III) the cost is higher by adopting a tissue culture mode.
