Seedling substrate using coffee processing residues as raw material and preparation method thereof

Abstract

The invention relates to the technical field of substrate preparation, and specifically discloses a seedling substrate using coffee processing residues as a raw material and a preparation method thereof. The seedling substrate consists of the following components in percentages by volume: 30%-34% of the coffee processing residues, 7.5%-8.5% of cow dung, 22.5%-25.5% of puffed perlite and 22.5%-25.5% of vermiculite; and the pH of the seedling substrate is 6.5-6.9, the total porosity is 71%-75%, and the water holding porosity is 49%-51%. The seedling substrate is prepared through three steps of raw material collection and pretreatment, fermentation and seedling substrate preparation. The seedling substrate prepared by using the coffee processing residues as the raw material has the advantagesthat the raw materials are easy to obtain, the formula is reasonable, nutrition is balanced, the seedling substrate is soft and breathable, and the operation technology is easy to grasp, so that theseedling substrate can effectively promote the growth and development of aboveground and underground parts of seedlings, therefore, the seedling cost is reduced, and the seedling cycle is shortened.

Description

technical field [0001] The invention relates to substrate preparation technology, and its specific field is a seedling cultivation substrate and a preparation method using coffee processing residues as raw materials. Background technique [0002] The seedling substrate is the carrier for the growth and development of seedlings and one of the key factors affecting the quality of seedlings. The seedling substrates used in the early days were mostly made of natural soil, which was not only high in quality, but also poor in water retention and ventilation. Since the mid-1970s, solid seedling substrates such as rock wool, polyurethane foam, glass fiber, phenolic resin, and polyester plastics have been widely used, which has promoted the formation and improvement of industrial seedling raising technology systems. The most used light seedling substrate. my country started late, but developed rapidly. Many domestic scholars have used the seedling substrate prepared by peat soil, ...

AI Technical Summary

Problems solved by technology

In view of this, the research and development of the excellent formula and manufacturing technology of the seedling substrate with coffee husk as the main raw material can not only provide a theoretical basis and specific technical methods for the substrate utilization of coffee husk from agricultural and forestry organic waste in Yunnan Province, but also solve the problem of In Yunnan forestry production, the traditional soil plastic bag seedlings have problems and defects such as large size, heavy weight, inconvenient transportation, and insufficient nutrients.
