Preparation method of dendrobium matrix

Abstract

The invention discloses a preparation method of a dendrobium matrix. The dendrobium matrix comprises a matrix fertilizer layer and a water filtering layer paved at the bottom of the matrix fertilizerlayer; the matrix fertilizer layer consists of 30-70% of saw dust, 10-40% of saw dust and 20-40% of a decomposed organic fertilizer, wherein the decomposed organic fertilizer is prepared by compostingcow dung, chicken manure, saw dust, potassium feldspar powder, phosphate rock powder and dolomite powder according to a weight ratio of 1:0.4:1:(0.12-0.2):(0.08-0.16):(0.08-0.16); and the filtering layer is formed by mixing potassium feldspar powder and dolomite powder according to a ratio of (1-2):1. The dendrobium matrix has remarkable advantages of looseness, air permeability, fertilizer conservation, water conservation and low cost. Dendrobium officinale cultivated by using the matrix prepared by the method can be harvested about one year in advance, and is superior to dendrobium officinale cultivated by other methods in appearance, internal quality and other aspects.

Description

technical field [0001] The invention belongs to the technical field of the substrate preparation method for cultivating dendrobium, and in particular relates to a preparation method of the dendrobium substrate. Background technique [0002] The substrate for cultivating Dendrobium prepared by prior art methods also has defects in air permeability, fertilizer retention, and water retention, and the price is high, which increases the cost of Dendrobium; the nitrogen, phosphorus, and Potassium fertilizer, and calcium and magnesium ions are relatively deficient, and there is no water filter layer to regulate the water content of the substrate in cultivation, and discharge excess water and nutrient solution. The harvesting period is generally only 2 to 3 years [0003] The southern part of my country has a subtropical monsoon climate, with concentrated and large rainfall every year, and the erosion of rainwater will cause the soil of tea gardens to harden; and because most of the...

Problems solved by technology

[0003] The southern part of my country has a subtropical monsoon climate, with concentrated and large rainfall every year, and the erosion of rainwater will cause the soil of tea gardens to harden; and because most of the soil in hilly areas is heavy in texture, poor in structure and low in fertility, the quality of tea leaves is not good, and the production efficiency is not good. high
