Nutrient soil for culturing dendrobium officinale

Abstract

The invention discloses nutrient soil for culturing dendrobium officinale, wherein the raw material components and the weight proportion of the nutrient soil are as follows: 10 to 40 parts of needle-point leaf soil, 10 to 20 parts of chitosan, 5 to 10 parts of pine bark, 1 to 3 parts of slaked lime, 10 to 20 parts of wormcast, 5 to 10 parts of river sand, 0.5 to 1.2 parts of liquorice, 5 to 8 parts of leaf mould, 3 to 5 parts of plant ash, 1 to 2 parts of maize straw putrefaction, 2 to 4 parts of peat soil, 1 to 2 parts of perlite, 0.1 to 0.2 parts of potassium permanganate, 10 to 20 parts of nutrient base fertilizer made of selenium-enriched mineral, 10 to 20 parts of Maifan-stone powder, 6 to 7 parts of ammonium nitrogen, 6 to 7 parts of nitric nitrogen, 10 to 12 parts of water-soluble phosphorus, 12 to 14 parts of water-soluble potassium oxide, 1 to 3 parts of water-soluble magnesium oxide, and 5 to 15 parts of compound nutrient base fertilizer. The nutrient soil for culturing the dendrobium officinale disclosed by the invention has the advantages that the seedlings of the dendrobium officinale can be directly placed into the soil for growth, the nutrient substances are abundant, the water retention capacity and the fertilizer retention capacity are good, the gas permeability of the soil is good, the cost is low, various minerals, such as calcium and phosphorus, are richened, the nutrition can be supplied continuously, and the pollution to the environment is avoided.

Description

technical field [0001] The invention relates to a nutrient soil for cultivating dendrobium officinale, which belongs to the technical field of plant nutrient soil. Background technique [0002] Nutrient soil is a bed soil specially formulated to meet the growth and development of seedlings, containing a variety of mineral nutrients, loose and ventilated, strong in water and fertilizer retention, and free from pests and diseases. Nutritionally, it is generally prepared by mixing fertile field soil and decomposed manure. [0003] Dendrobium is a plant of the genus Dendrobium Sw. of Orchidaceae. There are about 500 genera and more than 15,000 species of Orchidaceae in the world; Dendrobium is one of the largest genera in Orchidaceae. There are about 150 genera and 1,000 species of Orchidaceae in China, which are mainly distributed in the provinces and regions south of the Qinling Mountains and the Yangtze River Basin; most species of Dendrobium are concentrated between 15°30′ ...
