Greenhouse Psammophyte Cultivation Substrate

Abstract

The invention discloses a greenhouse psammophyte culture medium. Four different matrix layers, namely a base layer, an original soil layer, a nutritive layer and a covering layer, are sequentially paved from bottom to top, wherein the base layer is one or a mixture of more than one of quartz, feldspar, mica, kaolinite, limestone and granite, the thickness of the base layer is 30-80cm, and particle size is 1-5cm; the original soil layer is obtained by mixing chestnut soil, gray desert soil and desert sandy soil in volume ratio of (1-2):10:(1-3), and the thickness of the original soil layer is 20-60cm; the nutritive layer is a mixture of organic matters, inorganic minerals, inorganic fertilizer, microelement fertilizer and microbial fertilizer, and the thickness of the nutritive layer is 20-100cm; and the covering layer is formed by vermiculite and / or volcanic rock, and the thickness of the covering layer is 5-10cm. The greenhouse psammophyte culture medium is easy to produce and low in cost and can obviously improve the transplanting survival rate of greenhouse landscape psammophytes when applied to cultivation of the greenhouse landscape psammophytes.

Description

Technical field [0001] The invention relates to the field of horticulture cultivation. More specifically, the present invention relates to a greenhouse sand plant cultivation substrate. Background technique [0002] With the development of the national economy, various landscape greenhouses based on modern glass greenhouses have developed rapidly. The landscape greenhouse is a landscape space that can be controlled by an artificially constructed environment and meets the independence of plant growth. It is used to collect plants that grow in different regions, climatic conditions and their living environment, and comprehensively display plant forms, communities, habitats, cultural and economic uses It is a plant cultivation facility that realizes the functions of plant ex-situ conservation, science education, and leisure travel. [0003] The landscape greenhouse collects and conserves representative plants from all over the world, showing the rich biodiversity and its characteris...

Problems solved by technology

[0005] At present, in most landscape greenhouses in China, there are few cultivation substrates simulating the landscape of their original environment substrates, and most of them are directly used for cultivation with mixed nutrient substrates. However, the survival rate of this mixed nutrient substrate is Low, and the cost of the mixed nutrient matrix of the fully formulated fertilizer type is relatively high. In order to meet the indoor growth requirements of psammophytes, promote psammophytes to be strong, and better show the landscape of the original environment, the present invention is based on the psammophytes. Growth habit, development of a cultivation substrate for psammophytes in greenhouses
