Abstract

The invention relates to the technical field of culture substrates, and relates to a culture substrate based on peat sawdust. Raw materials of the culture substrate comprise peat sawdust, coconut chaff and fermented unlined upper garment wood chaff, wherein the quality of the peat sawdust accounts for 40-55% of the total mass of the culture substrate; the quality of the coconut chaff accounts for20-40% of the total mass of the culture substrate; the quality of the fermented unlined upper garment wood chaff accounts for 5-40% of the total mass of the culture substrate; the particle size of theculture substrate is not more than 30mm; and the pH value is 5-7.2. The culture substrate has comprehensive nutrition, and is rich in nitrogen, phosphorus, potassium, organic matter and humic acid, has long-lasting fertilizers, so that the nutrient requirements of long-term growth and development of plants can be met; and the culture substrate has good physical properties, good permeability and structure, proper water-air ratio, decomposition resistance and good physical structure stability, so that the defects of poor air permeability and uneven nutrients of the existing culture matrix can be effectively solved, and the aims of enhancing the air permeability of the culture substrate and fully and uniformly supplying nutrients can be achieved.

Description

technical field [0001] The invention relates to the technical field of culture substrates, more specifically, to a culture substrate based on peat sawdust. Background technique [0002] Substrate cultivation is a cultivation method that can fix the root system of plants in a specific container and absorb nutrients, water and oxygen from it, also known as soilless cultivation. The cultivation medium is the basis of soilless cultivation. In addition to the role of fixation, it also provides the plants with the necessary water, fertilizer, air and heat for the plant roots to absorb and utilize. Peat is one of the traditional cultivation substrate materials. It is a green, high-quality and high-efficiency nutrient soil, which contains a large amount of organic matter and humic acid. It can maintain soil moisture, supply nutrients, and promote plant production. Peat is divided into woody peat and herbaceous peat. South my country is dominated by woody peat, which is formed by bu...
