Seedling culture substrate using fermentation material to replace imported turf and preparation method thereof

Abstract

The invention discloses a seedling culture substrate using a fermentation material to replace imported turf and a preparation method thereof. The seedling culture substrate is prepared from the components in parts by weight: 50-65 parts of a mixed fermentation material, 15-20 parts of perlite, 10-15 parts of vermiculite and 10-15 parts of coco coir, wherein the mixed fermentation material is formed by mixed fermentation of vinasse and / or wool washing sludge and vinegar residues, and the vinasse is cassava vinasse. According to the preparation method, the vinasse and / or the wool washing sludge are / is fermented separately and then stacked with the fermented vinegar residues for further fermentation to obtain the mixed fermentation material, and then the mixed fermentation material is mixed with the perlite, the vermiculite and the coco coir for the fermentation again to obtain the seedling culture substrate. The mixed fermentation material is used for replacing the imported turf, so that the cost of the substrate is reduced, and the substrate is rich in nutritional ingredients and beneficial to seedling culture. According to the preparation method, a stacking fermentation mode is adopted, the fermentation effect is guaranteed, material turning links are reduced, and the substrate property can be controlled easily; and meanwhile, the seedling culture substrate using the fermentation material to replace the imported turf and the preparation method thereof has good green, environment-friendly and economic values.

Description

technical field [0001] The invention relates to a seedling raising substrate which uses fermented material instead of imported peat and a preparation method thereof. [0002] technical background [0003] In recent years, the way of raising vegetable seedlings in my country has been rapidly developing from traditional flat bed seedling raising and nutrient pot seedling raising to plug seedling raising, which has greatly promoted the research on the application of seedling raising substrates. In order to ensure the quality of seedlings, peat rich in nitrogen, potassium, phosphorus, calcium, manganese and other elements is listed as the preferred material. However, the peat charcoal produced in my country has a high degree of decomposition, a relatively high proportion of particles with a particle size of less than 0.5mn, a small saturated water holding capacity, and a high content of total N, total P, and total K, which makes the configured cultivation substrate difficult.

Problems solved by technology

However, the peat charcoal produced in my country has a high degree of decomposition, a relatively high proportion of particles with a particle size of less than 0.5mn, a small saturated water holding capacity, and a high content of total N, total P, and total K, which makes the configured cultivation substrate difficult. Slow emergence, poor plant uniformity, low seedling growth index, etc., so most of the seedling substrates use imported peat; under normal circumstances, the proportion of peat in the composition of the seedling substrate reaches 70%, which undoubtedly makes the The cost of seedlings has increased significantly

[0004] Some domestic scientific research institutes have more or less carried out some development and research on seedling substrates to replace imported peat, but they have not yet reached the practical stage. How to screen out suitable for plant growth conditions to cultivate high-quality seedlings and reduce seedling cost Material to replace the expensive imported peat, has become the focus of current seedling substrate screening and research
