Nutrient organic medium for dendrobium planting

Abstract

The invention discloses a nutrient organic medium for dendrobium planting. The nutrient organic medium is prepared from the following raw materials in parts by weight: 24 to 26 parts of pine bark, 38 to 42 parts of cottonseed cake, 28 to 30 parts of watermelon stalk, 3 to 4 parts of expanded perlite powder, 2 to 3 parts of polyacrylic acid, 1 to 2 parts of zinc chloride, 35 to 39 parts of plant ash, 1 to 2 parts of gamma-polyglutamic acid, 44 to 46 parts of wheat straw, 2 to 3 parts of urea, 18 to 20 parts of peat soil and a proper amount of water. By adopting the nutrient organic medium, the dosage of grass carbon as a non-renewable resource is reduced; materials are taken locally, and a large quantity of readily-available raw materials such as pine bark and watermelon stalk are adopted, so that the production cost of a culture medium is lowered remarkably; meanwhile, scientific configuration is performed specific to the nutrient demand features of dendrobium, so that the growth of dendrobium roots and stalks is facilitated, the goods quality of the dendrobium is improved, and the economic benefit of planting is increased.

Description

technical field [0001] The invention relates to the technical field of nutrient substrates, in particular to a nutrient organic substrate for planting dendrobium. Background technique [0002] Substrate cultivation is an important cultivation method, which is a soilless cultivation method that absorbs nutrients through the substrate. Due to its low requirements on the soil environment, simple equipment, water and fertilizer saving, etc., it is adopted by the majority of planting producers. application. With the continuous development of my country's planting industry and the continuous expansion of the planting area, the use of cultivation substrates is also increasing. The traditional substrates prepared from single raw materials such as peat and vermiculite or simply mixed can no longer meet the needs of planting. At this stage, the substrate generally has a single nutrient. At the same time, the physical properties of the substrate during use are unstable, poor water abso...

Problems solved by technology

With the continuous development of my country's planting industry and the continuous expansion of the planting area, the use of cultivation substrates is also increasing. The traditional substrates prepared from single raw materials such as peat and vermiculite or simply mixed can no longer meet the needs of planting. In this stage, the substrate generally has a single nutrient. At the same time, the physical properties of the substrate during use are unstable, poor water absorption, easy to collapse, and low added value. It is impossible to achieve high application value for specific cultivation objects and environments, which affects the growth of economic benefits.
