Problems solved by technology

[0004] After searching the documents of the prior art, it is found that Chinese patent documents, such as CN105712754A, is a special biochar-based soilless organic seedling-raising substrate for rice. In this invention, bamboo fibers are mixed with fermented particles, and ethanol solution is added for centrifugation to obtain The sediment is dried and pulverized, and the pulverized powder is roasted in a muffle furnace to obtain a special biochar-based soilless organic seedling raising substrate for rice; there are problems of high energy consumption and low production efficiency
For example, in CN103951515A, a kind of ecological agricultural cultivation soil, its preparation method and its application, the invention takes multifunctional multi-component ecological fertilizer, ecological organic substrate, mineral substrate and soil, and prepares ecological agricultural cultivation soil by compounding; there are high raw material source costs, Does not conform to the concept of harmonious development of green environmental protection
For example, in CN104584725A, a method for rapid fertilization of yellow soil tobacco fields is newly organized. This invention improves farmyard manure through base application, arranges wide and narrow ridges alternately, combines narrow and wide ridges with organic fertilizers, respectively fertilizes, green manure, straw mulch, etc. Steps; there are problems such as slow seedling raising speed and suitable for long-distance transportation of seedlings

Embodiment 1

[0066] The substrate for raising seedlings is made of the following raw materials by weight:

[0067]

[0068] (1) The agricultural and forestry wastes (crop straws) are cut and dedusted through pretreatment, and then enter the separation section, and the hemicellulose, cellulose and lignin stock solutions are separated by physical and chemical methods, and straw light ash and a small amount of organic liquid are produced, The separated hemicellulose is a liquid phase, and the lignin stock solution is separated, concentrated, purified and spray-dried to obtain solid lignin, and a membrane-treated supernatant is produced. A small amount of organic liquid and the membrane-treated supernatant are mixed and called For organic waste.

[0069] (2) Biomass sludge preparation:

[0070] ①The hemicellulose liquid enters the wastewater treatment system, and the suspended solids are removed in the pretreatment stage to produce primary sludge, the biochemical treatment stage removes a ...

Abstract

The invention belongs to the technical field of matrix preparing, and particularly relates to a matrix for culturing seedlings and a preparing method thereof. The matrix for culturing seedlings is prepared from biomass sludge, straw light ash, organic wastewater and a microorganism fermenting agent. The matrix for culturing seedlings is economical, efficient and good in safety, healthy seedling cultivating is facilitated, the matrix is not influenced by the weather, and application prospects are good.

Description

technical field [0001] The invention belongs to the technical field of substrate preparation, and in particular relates to a seedling-raising substrate and a preparation method thereof. Background technique [0002] With the progress and development of my country's agricultural modernization, crop production is changing from the traditional individual form to modern industrialized production that is scientific, intensive, commercial and market-oriented. As an important part of the industrialization of crop seedlings, industrial seedling cultivation has become a symbol of high technology. Industrialized seedling cultivation can give full play to the advantages of modern greenhouse facilities, shorten the time for seedling cultivation, save the amount of seeds used, and reduce the risk of seedling production. At the same time, it also has the following advantages: ① energy saving; ② high production efficiency; ③ good seedling quality, fast seedling growth, high survival rate;...
