Problems solved by technology

However, there are some defects in this conditioning method that need to be improved. For example, separating the acid-base adjustment and supplementing nutrients in the production process will increase the production process and increase the operating cost. A variety of products, it is likely that the conditioning effect will be poor due to neutralization or other inhibitory factors, which will weaken the proper effect of the product

Abstract

The invention provides a bioremediation soil conditioner which is composed of grass carbon, colza oil cake, a compound microorganism bacterium agent and sepiolite. The compound microorganism bacterium agent is selected from one or more of nitrogen fixation bacilli, organic phosphorus bacteria, inorganic phosphorus bacteria and silicate bacteria. The invention further discloses a preparation method of the bioremediation soil conditioner, and the method mainly comprises the steps of grinding, fermentation, drying treatment, detection and the like. The bioremediation soil conditioner can adsorb and chelate heavy metal in soil, decompose indissolvable phosphorus in soil and fix the nitrogen element in a molecular state in air so that crops can absorb and use the nitrogen element and meanwhile can improve the physicochemical property of soil and enhance air permeability and water-fertilizer retention capacity so that a good soil micro-ecological environment can be provided for the root system, multiple types of nutrients in soil can be in an effective activation state, the nutrient utilization rate is raised, and consumption of chemical fertilizer is reduced.

Description

technical field [0001] The invention relates to the field of agricultural production fertilizers, in particular to a bioremediation soil conditioner and a preparation method thereof. technical background [0002] In the existing technology, the use of soil conditioners is indispensable for agricultural production. Most of the soil conditioners currently on the market only have the function of adjusting acidity or alkalinity, and do not have the function of improving soil effective nutrients. The steps of alkaline and replenishing soil available nutrients are separate. However, there are some defects in this conditioning method that need to be improved. For example, separating acid-base adjustment and nutrient supplementation in the production process will increase the production process and increase operating costs. A variety of products are likely to have poor conditioning effects due to neutralization or other inhibitory factors, weakening the proper effect of the product...
