Embodiment 1

[0021] Preparation of a soilless culture medium suitable for rhododendron plants. Choose 10 parts by volume of mulch with a moisture content (percentage by weight) of 50 to 80%, mix it with 10 parts by volume of perlite to form a matrix, and press 5g / m 3 The rare earth consumption of matrix, dissolving rare earth nitrate with a small amount of water, enters mixing mixer together with leaf humus and perlite, after mixing uniformly, after diluting 500 times with the formaldehyde solution of 40% (percentage by weight), the mixed matrix is ​​sprayed wet, After sealing the plastic film for 2 days and nights, spread out the substrate, dry it in the air or expose it to the sun until there is no formaldehyde smell, and then the required soilless culture substrate can be obtained.

Embodiment 2

[0023] Repeat embodiment 1, have following difference: raw material component is as follows: moisture content 50~80% peat soil 10 volume parts, perlite 8 volume parts, vermiculite 8 volume parts, by 8g / m 3 Rare earth nitrate is added in proportion to the matrix. After diluting 1000 times with 40% chlorothalonil solution, spray the mixed substrate, seal the plastic film for 2 days and nights, spread the substrate and dry it to obtain the required soilless cultivation substrate.

Embodiment 3

[0025] Repeat embodiment 1, have following difference: raw material component is as follows: 10 parts by volume of peat soil with moisture content 50~80%, 5 parts by volume of slag after washing, 5 parts by volume of vermiculite, by 6g / m 3 Rare earth hydrochloride is added in proportion to the matrix. After the matrix is ​​evenly mixed, seal the plastic film, pass high-temperature steam until the temperature of the matrix reaches 90°C, keep it for 30 minutes, lift the film to cool down, and obtain the required soilless cultivation matrix.

Abstract

The invention discloses a soilless culture substrate suitable for ericaceae plants. Leaf mold or turfy soil is mixed with a porous material in a volume ratio of 10:5-20, and then rare earth is added into the substrate according to the use level of 5 to 10g / m3 of the substrate for uniform mixing to prepare the soilless culture substrate through disinfection. The product has the advantages of organic culture substrates and inorganic culture substrates, has the physicochemical properties of appropriate volume weight, electrical conductivity, porosity, pH value and the like, is suitable for culturing rhododendrons, and is an ideal substrate with high quality, sanitation, water conservation and fertilizer saving. The substrate can also be made into formed substrates in any shapes through further processing, so that plant root systems are protected more effectively, and the requirements of plant transportation and transplantation are met.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and relates to the production of a solid substrate for soilless cultivation, in particular to a soilless cultivation substrate particularly suitable for rhododendron plants. Background technique [0002] Soilless cultivation is a new type of cultivation method, which has become an important content of protected gardening and the main form of factory production of horticultural crops. It has been widely used in flower cultivation in recent years. Compared with traditional soil cultivation, it has the advantages of saving water, fertilizer and labor, improving crop yield and quality, avoiding soil continuous cropping obstacles, and not being restricted by geographical conditions. [0003] The cultivation substrate is the basis for plant growth under soilless cultivation conditions. The substrate is a growth medium that provides plants with a stable and coordinated structure of water, a...
