Novel organic substrate and preparation method thereof

Abstract

The invention discloses a novel organic substrate and a preparation method thereof. The method comprises the following steps: using feces of beasts and birds as earthworm food; providing environment suitable for earthworms to grow; sieving the feces generated through being processed by the earthworms into earthworm feces with the grain diameter between 4 and 6 mm; and matching and adding pelhamite, perlite and trace elements for being uniformly mixed to prepare the novel organic substrate, wherein the grain diameter of the pelhamite and the perlite is between 3 and 5 mm. The novel organic substrate comprises the following ingredients in percentage by weight: 58 to 71 percent of earthworm feces, 25 to 35 percent of pelhamite, 3.5 to 6.5 percent of perlite and 0.05 to 0.5 percent of trace elements. The invention has the advantages of simple preparation method, rich resources and low price of adopted materials, changes waste materials into useful materials, reduces the environment pollution, and has sufficient nutrition and stable performance. When being used for flower culture, the invention improves the quality of the flower pit tray seedling culture, and reduces the seedling culture steps such as fertilizing and the like.

Description

technical field [0001] The invention relates to a plant cultivation substrate, in particular to the composition of the flower cultivation substrate and a preparation method thereof, belonging to the technical field of plant cultivation. Background technique [0002] Substrate cultivation refers to a plant cultivation method that fixes its root system through a substrate and absorbs nutrients and oxygen in a certain place or container. According to statistics, 90% of the soilless cultivation forms in the world are substrate cultivation. The soilless cultivation substrate is a growth medium that can provide plants with a stable and coordinated water, air, and fertilizer structure. In addition to supporting and fixing the plants, it is more important to act as a nutrient and water carrier, so that the nutrients and water from the nutrient solution can be obtained. Transit, the plant root system selects and absorbs from it as needed. Substrate is the foundation and core of soi...

Problems solved by technology

[0016] (9) Insufficiency of the existing flowers and trees matrix in the market. The existing flowers and trees matrix in the market often causes compaction of itself and the underlying soil, poor permeability, poor nutrient balance, and small buffer performance, etc., which are not conducive to promoting the growth of seedlings. , and even cause the plants to show deficiency symptoms and some other physiological diseases, which affect the superiority of substrate cultivation; due to irrigation cultivation, various nutrients in the substrate are easily lost and enter surface water and groundwater

Pollution of the environment; after continuous use of most substrates, the microbial community will become monotonous, self-regulation and repair functions will be weakened, harmful microorganisms will breed, causing various diseases, and endangering the normal growth of seedlings
