Problems solved by technology

At present, the research on the substrate of Dendrobium is limited to considering the influence of substrate porosity, air permeability, water retention capacity, cultivability and epiphysis on the growth of Dendrobium, and there are few studies on the absorption of nutrients and active ingredient content of Dendrobium by substrate. Considering the comprehensive impact of

Embodiment 1

[0022] In terms of weight percentage, mix 70% camellia oleifera husk, 10% camellia oleifera meal, 5% chestnut shell, 5% walnut shell, and 10% polyurethane slow-release fertilizer, spread it on bluestone or bricks or install After potting, water it to make its humidity about 60%. After planting tissue cultured Dendrobium seedlings or transplanting Dendrobium seedlings, the survival rate is 99%. The average plant height, stem diameter, leaf length, leaf width, etc. are significantly better than other substrates. After one and a half years of growth in substrate cultured dendrobium, the chemical composition was detected, and the polysaccharide content of dendrobium was 49%.

Embodiment 2

[0024] In terms of weight percentage, mix 60% camellia husk, 20% camellia oleifera meal, 5% moss, 5% pine bark, and 10% polyurethane slow-release fertilizer, spread it on bluestone or bricks or put it in a pot After that, water it to make its humidity about 60%. After planting tissue cultured Dendrobium seedlings or transplanting Dendrobium seedlings, the survival rate is 99%. The average plant height, stem diameter, leaf length, leaf width, etc. are significantly better than other substrates. The chemical composition of the cultivated Dendrobium was detected after one year of growth, and the polysaccharide content of Dendrobium was 47.9%.

Embodiment 3

[0026] In terms of weight percentage, mix 50% camellia husk, 25% camellia oleifera meal, 5% moss, 5% chestnut shell, and 15% polyurethane slow-release fertilizer, spread it on bluestone or bricks or put it in a pot After that, water it to make its humidity about 60%. After planting tissue cultured Dendrobium seedlings or transplanting Dendrobium seedlings, the survival rate is 99%. The average plant height, stem diameter, leaf length, leaf width, etc. are significantly better than other substrates. The chemical composition of the cultivated Dendrobium was tested after one and a half years of growth, and the polysaccharide content of Dendrobium was 49.98%.

Abstract

A dendrobium cultivation matrix and a preparation method thereof are provided; the dendrobium cultivation matrix comprises tea oil processing residue oil tea fruit casing and oil tea dregs, organic inserts, and a biomass polyurethane slow release fertilizer; oil tea dregs after oil, tannin, and saponin extraction, and other ingredient after disinfection treatment are mixed by weight ration as the following: 30-70 of oil tea fruit casing, 10-40 of oil tea dregs, 10-30 of organic inserts, and 10-20 of biomass polyurethane slow release fertilizer; the said ingredients are uniformly mixed, and are filled in a basin or paved on the ground for cultivating dendrobium sprouts; the matrix is good in air permeability, can keep water, is uniform in water absorption, good in intergrouth property, high in survival rate, excellent in dendrobium growth vigor, can provide effective active ingredients for the dendrobium, has bactericidal effect, is hard to mildew, has no pathogen, and insects can hardly hide. The dendrobium harvest time of the dendrobium planted in the matrix can be 1-2 years, and dendrobium polysaccharide content can reach 40-50%.

Description

Technical field [0001] The invention involves a plant cultivation substrate and preparation method, especially a Dendrobium cultivation substrate and its preparation method with tea oil processing waste. Background technique [0002] CamelliaSpp.abel is an important wooden oil crop in my country. With the development of the camellia industry, the national category has 4 million hectares, the annual production of tea oil is 518,000 tons. At the same time Tons, more than 155 tons of oil tea meal.The main components of camellia and fruit shells are cellulose (13.87-20.95%), semi-cellulose (34.21-49.34%) and lignin (30.07-36.23%), as well7.67-13.8mg · G -1 To.Compared with pine bark, fir, sawdust and other tree species, the fiber crystal of the categaining shell (X-ray37.4-49.4%), the semi-cellulose content is high, and the cellulose non-crystalline zone and semi-cellulose can be very goodWater absorption and water preservation.Tea meal (also known as tea seed cake, alias tea bran, t...
