Embodiment 1

[0015] When the sporangia turn from red to yellow, and the cover of the sori is opened to reveal black spores, the mature spore fern leaves are picked, and the back of the leaves is placed on a large white paper, and after 5 days, Gently shake the leaves with your hands, then remove the leaves, remove the collected spores, and put them in paper bags for later use. Mix the matrix sand + peat + perlite (1:1:1, volume ratio) thoroughly; put the spores in a container filled with clean water, stir evenly, and make a suspension; draw the suspension containing spores with a syringe The turbid liquid is evenly poured on the substrate in the pot, and gently suppressed on the surface of the substrate with a round wooden board with handles, so that the spores and the substrate can fully contact. The pot is placed in an impermeable plastic turnover box, and the bottom of the box The water level is kept at about 1.5cm to ensure that the substrate can fully absorb water and ensure the moist...

Abstract

A conventional Dryopteris erythrosora spore propagation method is mainly characterized in that Dryopteris erythrosora spores are prepared into suspension and the suspension is evenly poured onto mediums contained in an earthen pot by using a syringe; sowing mediums are mixtures of sand, peat and pearlite which are mixed by volume ratio of 1:1:1; the earthen pot into which the spores are sown is put into a transfer case, the height of the water-soaked bottom of the transfer case is 1.5cm and the water-soaked bottom of the transfer case is covered by plate glass; the spores are cultured in the sunshade position of a greenhouse at 25 DEG C to 35 DEG C under the condition that direct sunlight is avoided; juvenile sporophytes are obtained after culture and are respectively transplanted into transplanting mediums I which are formed by leaf mould, peat and sand in an evenly mixing way by volume ratio of 1:1:1, transplanting mediums II which are formed by sand, pearlite and peat in an evenly mixing way by volume ratio of 1:1:1, transplanting mediums III which are formed by peat and garden mould in a mixing way by volume ratio of 1:1, and reference mediums which are formed by garden mould; and the juvenile sporophytes are cultured under the same conditions. By using the characteristic that the germination and the fertilization of the spores need water and by applying pot planting, water soaking and moisture preservation to Dryopteris erythrosora spore propagation, the germination rate of the Dryopteris erythrosora spores, the seedling rate and the survival rate of the transplant sporophytes are effectively improved; in the propagation process, any sterilization process is not required, the processes are reduced, the pollution is reduced, the cost is saved, the operation is simple and convenient and the rapid propagation and the mass production of seedlings are facilitated; the survival rate of the transplanted juvenile spore seedlings reaches more than 85 percent.

Description

technical field [0001] The invention relates to a spore propagation method for ferns, in particular to a quick and easy spore propagation method for propagating Trichofern spp. Background technique [0002] Dryopteris erythrosora is a medium-sized terrestrial fern of the evergreen herbaceous plant belonging to the family Dryopteridaceae. Widely distributed in East China, South China and Southwest China, it grows in acidic or weakly acidic soil, prefers a damp environment, and is distributed below 300m above sea level in Jiangsu. The rhizomes of Trichofern erythrophylla grow obliquely, and the leaves gather at the top of the rhizomes. A rare evergreen ornamental fern in Nanjing. Under the cultivation conditions, the red fern began to germinate and roll its leaves in early March, and began to unfold its leaves in early April. The sporangia appeared around April 5, and matured around June 10. With the new leaves The germination and spore maturity period can be extended to th...
