Multifunctional plant conditioning matrix

Abstract

The invention relates to a multifunctional plant conditioning matrix. The multifunctional plant conditioning matrix comprises, by weight, 20 to 300 parts of a rooting agent, 10 to 70 parts of a water-retaining agent, 1000 to 2000 parts of soil, and 10 to 50 parts of a heavy metal ion adsorbent. The heavy metal ion adsorbent comprises orange peel, corn, and bran which are taken as base materials, and a mixed bacterial agent which is taken as a modifier and comprises beer yeast, Gordon amarae, aspergillus oryzae, cladosporium sp, and rhizopus nigricans. Beneficial effects are that: organic combination of agricultural crop with bacteria is realized; heavy metal ions can be absorbed effectively; water retention, slow release, fertilizer retention, soil improvement, and biological activation effects are achieved; transplanted plant survival rate is increased, and soil structure is improved at the same time; the ingredients of the multifunctional plant conditioning matrix are degradable organic matters, so that environmental pollution is not caused.

Description

technical field [0001] The invention belongs to the field of soil improvement, and in particular relates to a multifunctional plant conditioning base. Background technique [0002] my country's soil is facing the constant threat of heavy metal pollution and desertification. At present, researchers at home and abroad have conducted in-depth and extensive research on various methods of biosorbents to control heavy metal pollution. Biosorbents mainly include bacteria, fungi, algae, natural organic matter, and agricultural and forestry waste. The biosorption method uses biosorbents to treat and recover heavy metals. Compared with other traditional heavy metal treatment methods, it has the advantages of low raw material prices, various types, wide sources, high adsorption efficiency of heavy metals, simple adsorption equipment and easy operation, and tolerance to organic matter. High performance and wide application range, there are many types of biosorbents and extremely wide ...
