Ecologically agricultural cultured soil as well as preparation method and application thereof

Abstract

The invention discloses ecologically agricultural cultured soil as well as a preparation method and an application method thereof. The preparation method comprises the following steps: A, uniformly mixing organic raw materials and mineral fertilizer raw materials, and adding beneficial bacteria to ferment to obtain a functional multielement ecological fertilizer; B, culturing edible bacteria on a large scale or breeding medium- and small-sized livestock in a fermenting bed on a large scale in a composite heliogreenhouse in a soil wall-crown structure to obtain a byproduct as an ecological organic matrix; C, taking loose coal ash, slags, decomposed coal or gangue with pores as a mineral matrix; D, using common field surface soil; and E, compounding the functional multielement ecological fertilizer, the ecological organic matrix, the mineral matrix and the soil to prepare the ecologically agricultural cultured soil. According to the invention, the multifunctional multielement ecological fertilizer and the ecological organic matrix are produced with high quality and efficiency on a large scale throughout the year dependent on abundant planting and breeding of agriculture and forestry as well as biomass byproduct resources, so that the modern ecologically agricultural cultured soil is built.

Description

technical field [0001] The invention relates to the technical field of modern ecological agriculture, in particular to a basic, common and platform-based ecological soil comprehensive cultivation technology constructed under the guidance of the concept of modern ecological agriculture. Background technique [0002] Greenhouse soilless cultivation has risen in my country in recent years, and soilless cultivation is also called "substrate cultivation" or "organic substrate cultivation", such as the "organic ecological soilless cultivation technology" developed by researcher Jiang Weijie of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences and others (" New Technology of Vegetable Soilless Cultivation" edited by Jiang Weijie et al., June 2006, published by Jindun Publishing House), "Soilless Cultivation Technology of Solar Greenhouse Vegetable Organic Substrate Type" developed by Professor Yu Xianchang of Shandong Agricultural University ...

AI Technical Summary

Problems solved by technology

[0003] 1. Pre-fermentation treatment of organic fertilizer and organic matrix, using natural bacteria or aerobic bacteria outdoor or in the stacking or tank fermentation, high temperature fermentation of natural bacteria or aerobic bacteria, in killing harmful bacteria, insect eggs, grass seeds At the same time of harmless treatment, the consumption of organic matter is large, the stacking fermentation is greatly affected by the outside world, the compost quality is unstable, manual or mechanical turning is required, the labor intensity is high, and the investment in equipment is high

[0004] 2. The sources of raw materials for organic fertilizers and organic substrates are relatively narrow, and it is not yet possible to fully and efficiently utilize agricultural and forestry planting and breeding plus biomass (by-product) resources. The pre-fermentation time of organic substrates is relatively long, especially the pre-fermentation treatment time of organic substrates for forestry by-products such as sawdust Longer, aerobic bacteria fermentation takes 1-3 months, natural bacteria fermentation takes 1-2 years, and cannot be continuously supplied in large quantities; there are only a few mineral substrates such as fly ash and sand, wh
