Problems solved by technology

However, the mycorrhizal fungus of Cypripedium is an endophytic fungus, and it will gradually die away from the root system of Cypripedium. Plant mycorrhizal fungi are able to connect with other plant roots or dead organic matter in the soil through exogenous hyphae on the root surface

Embodiment 1

[0025] Step 1, collection of bacteria source: For Cypripedium grandiflora that has been introduced and cultivated for 8 months and has grown well, take 150g of moist rhizosphere soil below 5cm of the surface layer, put it in a container placed in a cool environment, and stir it 3 times to make it Mix evenly to obtain the source soil of bacteria;

[0026] Step 2, collecting crop stalks and livestock manure, preparing polyvinyl alcohol, aldehyde, potassium carbonate, acid (hydrochloric acid of 2moL / L);

[0027] Step 3, preparation of organic waste: organic waste is fermented through aerobic composting, and high-temperature aerobic composting is used to prepare fermented products: the crushed crop straw and livestock and poultry manure are mixed in a mass ratio of 1:1, and the moisture content is adjusted to 45 % Carry out high-temperature aerobic fermentation. When the temperature of the pile body reaches 55°C, turn the pile once a day; stop the fermentation after the temperatur...

Embodiment 2

[0033] Step 1, bacteria source collection: get 3 clusters of Cypripedium grandiflora that grow well under the conditions of wild populations, each get 30g of the wet soil of the root system of Cypripedium grandiflorum below its surface layer 5cm, take 30g, put it into the In a container in a cool environment, stir 4 times to make it evenly mixed;

[0034] Step 2, collecting crop stalks and livestock manure, preparing polyvinyl alcohol, aldehyde, potassium carbonate, acid (hydrochloric acid of 2moL / L);

[0035] Step 3, preparation of organic waste: organic waste is fermented through aerobic composting, and high-temperature aerobic composting is used to prepare fermented products: the crushed crop straw and livestock and poultry manure are mixed in a mass ratio of 1:2, and the moisture content is adjusted to 45 % Carry out high-temperature aerobic fermentation. When the temperature of the pile body reaches 55°C, turn the pile once a day; stop the fermentation after the temperatu...

Abstract

The invention discloses a preparation method of a cypripedium macranthum introduction cultivation substrate. The method includes the steps: firstly, collecting fungus resources; secondly, collecting crop straws and livestock and poultry manure; thirdly, preparing organic waste; fourthly preparing charcoal; fifthly, placing fermented mixed materials of the organic waste and the charcoal on harden ground, spreading the mixed materials into a thin layer, and drying the mixed materials in the sunlight; sixthly, preparing compound macromolecule water and fertilizer conservation materials, and crushing, granulating and screening the materials to obtain substrate particles; seventhly, preparation: mixing the proliferated fungus resource soil and the substrate particles according to weight ratio of 1:3-6:3, and repeatedly turning over and shoveling mixture to uniformly mix the mixture to obtain the special orchid active cultivation substrate. At least one of the crop straws and livestock and the poultry manure is carbonized at the temperature of 450-800 DEG C under anaerobic conditions to obtain the charcoal. The cultivation substrate is good in air permeability, water and fertilizer conservation characteristics are stable, the shortcomings of easy hardening of existing cultivation substrate and difficult water and fertilizer conservation are overcome, and the requirements of cypripedium macranthum growth and development for mycorrhiza fungi can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of cultivation substrates, in particular to a method for preparing a cultivation substrate for the introduction of Cypripedium grandiflorum. Background technique [0002] Cypripedium macranthum Sw. (scientific name: Cypripedium macranthum Sw.): The plant is 25-50 cm high with thick and short rhizomes. Stem erect, slightly pubescent or glabrous, with several sheaths at the base and 3-4 leaves above the sheaths. Leaves elliptic or elliptic-ovate. Inflorescence terminal, with 1 flower, large, purple, red or pink, usually with dark veins, rarely white; petals lanceolate, 4.5-6cm long, 1.5-2.5cm wide, apex acuminate, not twisted , with villous hairs at the base of the inner surface; lip deeply cystic, subglobose or elliptic. Capsule narrowly elliptic, about 4cm long, glabrous. The flowering period is from June to July, and the fruiting period is from August to September. [0003] Cypripedium grandiflorum gro...
