The method is beneficial to greatly improving the germination rate and the seedling rate of the sub-plants, shortening the seedling time, breaking through the seasonal limitation of the plant-divided seedling of the ciliate desert-grass and realizing annual production.
Description
Technical Field
The invention relates to the technical field of pteridophyte seedling culture, in particular to a pteris vittata seedling culture method and device.
Background
Ciliate desert-grass is a kind of terrestrial fern, and is widely distributed in warm and humid mountain forest in tropical and subtropical areas in the south of Qinling mountain in China. As an arsenic super-enrichment plant, the arsenic super-enrichment plant has great potential in the technology of restoring soil polluted by compound heavy metal, and has been successfully applied to the field restoration of the soil of the polluted farmland in the southern mining area of China. Meanwhile, the ciliate desert-grass can be used as a pot culture for appreciation, the feathery compound leaves of the ciliate desert-grass are extremely beautiful and evergreen in four seasons, are relatively shady, and are one of the popular indoor leaf-watching plants.
Since ciliate desert-grass is not flowering and fruitless, it can not be propagated by seeds. In the prior art, the propagation of ciliate desert-grass generally adopts three methods of mature spore propagation, plant division propagation and tissue culture propagation. Tiny spores need to be treated in advance during spore propagation, the seeding quantity is not easy to control, seedling culture failure is easy to cause due to mildew infection through high-density seeding of spore powder, and the spore germination rate and the germination time are extremely easy to be influenced by environmental factors. The operation of tissue culture and spore propagation is more complicated, the requirements on the professional and technical properties of operators are higher, and the plant division propagation is widely applied to the propagation of the ciliate desert-grass due to the characteristics of fast seedling formation and low operation technical requirements. But the time suitable for the propagation of the plant is limited, mainly focusing on 5-6 months; the propagation coefficient of the plant division propagation is lower, generally, only 2-3 plants can be propagated by one stock plant, and the propagation material waste is serious.
Disclosure of Invention
The invention mainly aims to provide a ciliate desert-grass seedling raising method and equipment, and aims to solve the technical problems of limitation of ciliate desert-grass propagation expanding operation time and low propagation expanding coefficient.
In order to achieve the purpose, the invention provides a ciliate desert-grass seedling culture method, which comprises the following steps:
cutting the rhizome of the ciliate desert-grass mother plant into sub-plants;
sequentially and respectively soaking the strains in a carbendazim solution, a copper quinoline copper tebuconazole solution and an amino acid water-soluble fertilizer;
placing the daughter plant into a plug tray, and covering the daughter plant in the plug tray with a culture medium;
and performing moisture preservation culture, temperature control culture and light supplement culture on the strains in the plug tray.
Preferably, the daughter strain is 1-5cm in length and/or comprises 1-3 germinating nodes.
Preferably, the concentration of the carbendazim solution is 1000-2000 times of the solution, and the soaking time is 5-30 minutes; the concentration of the quinoline copper tebuconazole copper preparation solution is 1000-2000 times of that of the solution, and the soaking time is 5-10 minutes; the concentration of the amino acid water-soluble fertilizer is 50-100 times of the concentration of the amino acid water-soluble fertilizer, and the soaking time is 5-10 minutes.
Preferably, the culture medium is a mixture of peat soil and hydrated lime with the mass ratio of 100 kg: 1-10 kg.
Preferably, the size of the peat soil particles is 1-14 meshes, and the water content of the peat soil is 50% -75%.
Preferably, the ciliate desert-grass seedling raising method is applied to seedling raising equipment, the seedling raising equipment comprises a box body and an atomizing spray head,
the step of performing moisture-preserving culture on the daughter plants in the plug tray comprises the following steps:
and putting the hole disc into the box body, and starting an atomizing nozzle arranged above the hole disc at intervals of 3-6 hours for spraying for 5-20 seconds each time so as to keep the humidity of the culture medium at 50-75%.
Preferably, the ciliate desert-grass seedling culture method is applied to seedling culture equipment, the seedling culture equipment comprises a box body and a heater,
the temperature-controlled culture of the plug tray comprises the following steps:
and putting the plug tray into the box body, and starting a heater to keep the temperature in the box body to be more than 18 ℃.
Preferably, the ciliate desert-grass seedling raising method is applied to seedling raising equipment, the seedling raising equipment comprises a box body and a light supplement lamp,
the light supplementing culture of the plug tray comprises:
and (3) putting the plug tray into the box body, and after the centipede grass plant grows out a green bud, starting a light supplement lamp, wherein the light supplement time is 6-10 hours each time, and the light period is 12-15 hours.
Preferably, after the steps of performing the moisturizing culture, the temperature-controlled culture and the light-supplemented culture on the plug tray, the method further comprises the following steps of:
when the green bud of the ciliate desert-grass grows to 3-5cm high, carrying out conventional seedling hardening and transplanting and field planting.
In addition, in order to achieve the above object, the present invention also provides a ciliate desert-grass seedling raising device, comprising:
the box body is internally provided with a support piece;
the plug is arranged on the support piece and used for placing the ciliate desert-grass seed plants and the culture medium;
environmental control system, including light filling device, water spraying system and heater, the light filling device is used for carrying out the light filling to the sub-trunk in the cave dish of putting into the incubator and cultivates, water spraying system includes atomizer, water spraying system is used for moisturizing the cultivation to the sub-trunk in the cave dish of putting into the incubator, the heater is used for carrying out the temperature-controlled cultivation to the sub-trunk in the cave dish of putting into the incubator.
