Problems solved by technology

[0005] However, in the process of artificially planting Cymbidium orchids, the cultivation substrate with peat as the main material not only has poor adsorption and can easily cause the loss of nutrients, but also easily causes soil compaction during long-term use, which seriously affects the growth of Cymbidium orchids. Normal growth, need to be resolved urgently

Abstract

The invention discloses a cymbidium hybridum culture medium. The culture medium taking peat as a main material is poor in adsorbability and extremely likely to cause loss of nutrient substances, and soil hardening is extremely easy to cause in long-time use, so that normal growth of cymbidium hybridum is seriously influenced. The cymbidium hybridum culture medium is prepared from the following raw materials in parts by weight: 100 to 200 parts of peat, 10 to 20 parts of bark, 40 to 60 parts of mushroom dreg, 20 to 60 parts of wormcast, 1 to 2 parts of 2-acrylamide-2-methylpropanesulfonic acid, 4 to 10 parts of hyperbranched polyamide-amine and 0.2 to 4 parts of ceric ammonium nitrate. The invention further discloses a preparation method of the cymbidium hybridum culture medium. The cymbidium hybridum culture medium has unique physicochemical properties such as rich pores, large specific surface area, strong adsorbability and stability, the soft and loose structure state of the medium can be maintained according to the growth characteristics of cymbidium hybridum, hardening of the medium is avoided, and the water-retaining property and air permeability of the medium are enhanced.

Description

technical field [0001] The invention relates to the technical field of cultivation substrates, in particular to a cymbidium cultivation substrate and a preparation method thereof. Background technique [0002] Cymbidium hybrid (scientific name: Cymbidium hybrid) is a horticultural species of the genus Orchid. It is selected from large-flowered original species such as exclusive spring, tiger head orchid, ivory white, jasper orchid, beautiful flower orchid, and yellow cicada orchid through multiple generations of hybridization. It is a perennial evergreen herb with well-developed root system, cylindrical, fleshy, thick and plump. The plant height can reach 150 cm, and the pseudobulbs are thick and coaxial. Pseudobulbs have nodes and hidden buds on the nodes. The leaves are clustered, the leaves are banded, leathery, the racemes, and the tepals are petal-shaped. The flowers are large, and the flower colors are red, yellow, emerald green, white, and multiple colors; the frui...
