Embodiment 1

[0015] In early November, select the leaves of Osmunda sinensis with sporangia clusters on the back of the leaves, and put them in a polypropylene edible fungus plastic bag. After a month, after seeing the sporangia clusters behind the leaves of Osmunda sinensis stripped off, retract the plastic bag. A large number of mature spores of Osmunda japonica have been installed, put it in a cool place for later use;

[0016] Dig an appropriate amount of vegetable garden soil, dry and crush; add 1000ml of distilled water for every 500g of dry fine soil according to the proportion, boil it for 1 hour, cool and clarify; take the upper clear liquid, put it into a 1000ml Erlenmeyer flask, and add (NH 4 ) 2 SO 4 0.5g, KNO 3 2g, KH 2 PO 4 0.4g, Mg 2 SO 4 ·7H 2 O0.2g, 4g agar powder, add distilled water to the 1000ml mark, stir and heat until the agar dissolves; place 30 petri dishes of 120mm size horizontally, and pour 1000ml of culture fluid into the petri dishes roughly evenly while hot. Cove...

Embodiment 2

[0022] After the temperature warms up in spring, place a foam board with a size of 1m×1.5m×5cm on the built pool. Spread the peat soil and fine sand on the foam board with a thickness of 3-5cm to make several small borders; use distilled water Rinse the plastic bags containing the spores of Osmunda spores one by one to obtain a solution containing spores of Osmunda spores. After filtering, spray evenly on the mixed soil, spraying 50ml per square meter; pour water into the pool, fix the foam board, set up the support, and cover with the film. There is a sunshade net on the roof; the pool should be kept with water in the early stage to create a relatively shady and wet environment for the initial germination and growth of Osmunda spores. At the beginning of April, the solution containing Osmunda spores was evenly sprayed on the seedling bed. The green prothallium germinates from the border, the size is only 0.5-1.0mm; at this time, water is sprayed every day for 15 days; after 5 w...

Abstract

The invention relates to a factory-like rapid cultivation method for dicrano pteris pedata seedlings. The method comprises the steps of dicrano pteris pedata spore collection, artificial cultivation, transplanting and seedbed management. The artificial cultivation is spore transplanting cultivation and comprises the steps of culture medium preparation, spore inoculation, management and the like. The artificial cultivation can also be spore direct seeding cultivation and comprises the steps of cultivation trench building, spore direct seeding, management and the like. Compared with the background art, the factory-like rapid cultivation method has the advantages that dicrano pteris pedata seedlings can be produced in a large scale in a factory-like mode, the dicrano pteris pedata seedling cultivation period is shortened, the seedling emergence number is improved exponentially, the seedling quality and transplanting survival rate are high, and the bag cultivation seedling cost is greatly reduced.

Description

1. Technical Field [0001] The invention relates to the field of biotechnology, in particular to a method for rapid industrialization of seedlings of Osmunda japonica. 2. Background technology [0002] Dicranopterisdichotoma (Thunb.) Bernh. is a Gleicheniaceae pteridophyte. It is widely distributed in various provinces south of the Yangtze River in my country. It is the most important indicator plant in southern red soil mountains under humid and hot climate conditions. It is extremely drought-tolerant and barren, and its traces can always be seen in areas with extreme soil erosion where there is no humus and the available nitrogen, phosphorus and potassium in the soil are almost zero. As long as there are shady and wet conditions, it can always be seen. Osmunda has a well-developed root system, and the underground stem has the characteristics of infinite branching, which can cross branch and nodally root. After the huge root system forms a dense root network, it has strong resist...
