CN105152744A - Seedling growing matrix improving pteridium aquilinum spore seedling rate - Google Patents

Abstract

The invention relates to a seedling growing matrix improving pteridium aquilinum spore seedling rate. The seedling growing matrix is prepared from the following raw materials: 100-150 parts of minced reed, 10-15 parts of urea formaldehyde foamed plastic, 50-60 parts of pine needle mulch, 5-8 parts of bone meal, 5-8 parts of silicate bacterial fertilizer, 0.05-0.07 part of kinetin, 1-1.5 parts of betaine, 0.001-0.003 part of spermidine, 3-5 parts of inositol residue, 0.08-0.1 part of vitamin B1, and 0.24-0.3 part of vitamin B2. The seedling growing matrix is relatively light, possesses relatively good moisture retention and insect-pest prevention effects, is capable of improving spore vitality and germination ability and inducing spore to germinate earlier, and is capable of substantially improving the seedling rate of pteridium aquilinum spore.

Description

A kind of seedling medium improving bracken spore seedling rate

Technical field

The present invention relates to a kind of pteridophyte cultivation matrix, be specifically related to a kind of seedling medium improving bracken spore seedling rate.

Background technology

Fiddlehead is a kind of per nnial herb, grows at theropencedrymion or broad-leaf forest with gap and hill covered with grass ground, has huge underground rhizome, can prevent erosion; Ground petiole and spire can be done edible wild herbs and eat, there is the effects such as wind dispelling wets, calms the nerves, diuresis, with its unique flavor, nutritious, and favor by people, a large amount of spores utilizing fiddlehead to produce carry out artificial propagation, are the effective ways improving fiddlehead breeding coefficient, in prior art, directly in matrix, sow bracken spore makes its Germination And Seedling in many employings, and different substrates has larger impact to bracken spore seedling rate.

Summary of the invention

The present invention, to improve for the purpose of bracken spore seedling rate, provides a kind of bracken spore seedling medium.

The technical solution used in the present invention is, a kind of seedling medium improving bracken spore seedling rate, and its substrate formula is:

Reed 100-150 part, urea-formaldehyde foamed plastics 10-15 part, pine soil 50-60 part, bone meal 5-8 part, silicate bacterial fertilizer 5-8 part, kinetin 0.05-0.07 part, trimethyl-glycine 1-1.5 part, spermidine 0.001-0.003 part, inositol dregs 3-5 part, vitaminB10 .08-0.1 part, Lin Suanna Vitamin B2 Sodium Phosphate 0.24-0.3 part.

Substratum quality of the present invention is comparatively light, has better moisturizing and insect-pest effect, can improve vigor and germination Lee of spore, and inducing spore is sprouted ahead of time, can significantly improve the seedling rate of bracken spore.

Embodiment

Embodiment 1: a kind of seedling medium improving bracken spore seedling rate, its substrate formula is:

Reed 100 parts, urea-formaldehyde foamed plastics 10 parts, pine soil 50 parts, bone meal 5 parts, silicate bacterial fertilizer 5 parts, kinetin 0.05 part, trimethyl-glycine 1 part, spermidine 0.001 part, inositol dregs 3 parts, vitaminB10 .08 part, Lin Suanna Vitamin B2 Sodium Phosphate 0.24 part.

Embodiment 2: a kind of seedling medium improving bracken spore seedling rate, its substrate formula is:

Reed 150 parts, urea-formaldehyde foamed plastics 15 parts, pine soil 60 parts, bone meal 8 parts, silicate bacterial fertilizer 8 parts, kinetin 0.07 part, trimethyl-glycine 1.5 parts, spermidine 0.003 part, inositol dregs 5 parts, vitaminB10 .1 part, Lin Suanna Vitamin B2 Sodium Phosphate 0.3 part.

Below in conjunction with control experiment, the present invention will be described:

Select ripe fiddlehead brown oidium of gathering then, after fully rinsing with sterilized water, equivalent is seeded in matrix of the present invention, every square metre of sowing 9-10 grain common vetch dish spore, growth humidity remains on 75%, and growth temperature remains on 26 DEG C, and growth intensity of illumination keeps 24 h light at 1800lx.

After planting, sprout, enter the protonema phase after 5-6 days, enter the gametophyte phase after 8-9 days after spore 1-2 days, after 26-27 days, sporophyte first leaf is carried out, and seedling rate can reach 62.18%.
