Special orchid culture media for subtropical regions and preparation method thereof

Abstract

The invention discloses a special orchid culture media for subtropical regions and a preparation method thereof. The culture media comprises semi-weathered purple sandshale, slag, topsoil, rice husk, edible fungi cultivation residual materials and pine bark fragments with the volume ratio of 0.15-0.20:0.10-0.15:0.10-0.15:0.15-0.20:0.15-0.20:0.20-0.25; or semi-weathered purple sandshale, pine barkfragments, tea seeds or rapeseed meal and sawdust with the volume ratio of 0.17-0.25:0.45-0.50:0.03-0.05:0.25-0.30. According to the invention, the subtropical regions have abundant deposits of the semi-weathered purple sandshale which contains a plurality of trace elements required by the orchid and has the advantages of loose structure and moderate density, thus the media weight can be reduced,and the water permeability is good; semi-decomposed wood chips, coal slag, pine barks and edible fungi cultivation residual materials are recycled and supply nutrition to the orchid, thus the huge market potential is shown.

Description

technical field

[0001] The invention belongs to the field of research and development of orchid cultivation substrates in subtropical regions, and in particular relates to two subtropical region-specific orchid cultivation substrates and preparation methods thereof. Background technique

[0002] Orchids are elegant, beautiful and mysterious plants. In ancient my country, orchids were often praised as gentlemen, elegant scholars, and youren. Orchids are famous flowers in China and the world, and they are also very popular flowers. In nature, orchids have different habits and are distributed in different geographical environments. Therefore, it is very important to choose a suitable cultivation substrate for cultivation under artificial conditions. The quality of growing orchids lies in growing the roots. To grow the roots well, the key is to choose clean, loose, breathable and moisturizing plant materials. At present, the plant materials used for orchid cultivation at home a...

Examples

Embodiment 1

[0057] The raw materials are taken according to the volume ratio of semi-weathered purple sand shale: slag: soil: rice husk: edible fungus cultivation residue: pine bark fragments = 0.15: 0.10: 0.10: 0.15: 0.15: 0.20; then follow the following preparation steps:

[0058] 1) The raw material of semi-weathered purple sand shale needs to be selected and processed as follows: choose a block with a diameter of 0.5-3cm, and a thickness of 1-5mm, and a length and width of 1-5cm. Purple sand shale debris block, turned and passivated sharp water chestnut, set aside;

[0059] 2) Preparation of mixed raw materials of slag and soil: sieve the cinder produced after coal combustion (particle size 1-2cm) and mix with the plow layer soil according to the volume ratio of the above raw materials for use;

[0060] 3) Preparation of mixed raw materials of rice husk, edible fungus cultivation residue and pine bark fragments: mix rice husk, edible fungi cultivation residues and pine bark fragments ...

Embodiment 2

[0063] The raw material formula is semi-weathered purple sand shale: slag: soil: rice husk: edible fungus cultivation residue: pine bark fragment volume ratio = 0.20: 0.15: 0.15: 0.20: 0.20: 0.25; rice husk, edible fungus cultivation residue 1. The pine bark fragments were naturally heaped and rotted for 2-3 months into a semi-decomposed state, and other preparation steps were the same as in Example 1. The obtained substrate is used for cultivating orchids, and the growth is obviously better than that of orchids cultivated on common substrates.

Embodiment 3

[0065] The raw material formula is semi-weathered purple sand shale: slag: soil: rice husk: edible mushroom cultivation residue: pine bark fragment volume ratio = 0.18: 0.12: 0.12: 0.18: 0.18: 0.22; the preparation steps are the same as in Example 1. The obtained substrate is used for cultivating orchids, and the growth is obviously better than that of orchids cultivated on common substrates.
