Abstract
The invention discloses a soil culture medium suitable for heavy metal pollution. The soil culture medium comprises the following components in parts by weight: 30-40 parts of clay, 10-15 parts of montmorillonite, 50-70 parts of organic matters, 2-4 parts of iron-manganese-aluminium oxide and hydroxide, 3-5 parts of slow release fertilizers, 0.5-0.8 part of aggregating agent, 1-3 parts of nettle seeds and 1-2 parts of lotus corniculatus seeds. The soil culture medium can reduce the contents of heavy metals in soil.
Description
technical field
The present invention relates to a kind of soil culture medium for soil improvement, especially a kind of plant-growth soil culture medium that is specifically designed to heavy metal contamination.
technical background
Fast development along with global economy, pollutent containing heavy metal enters soil by all means, cause soil severe contamination, affect output and the quality of farm crop, and can pass through the health of food chain harm humans, also can cause the further deterioration of water surrounding, even cause the havoc of the ecosystem.
Summary of the invention
The object of the invention is to the soil for heavy metal contamination, the artificial soil substratum that a kind of raw material sources are extensive, with low cost, can turn waste into wealth is provided.
For realizing above object, a kind of soil culture medium that is suitable for heavy metal contamination of the present invention, its component and weight part thereof are: clay 30-40 part, montmorillonite 10-15 part, organic 50-70 part, ferrimanganic aluminum oxide and oxyhydroxide 2-4 part, slow-release fertilizer 3-5 part, granule agent 0.5-0.8 part, nettle grass seed 1-3 part, Root or stem of Littleleaf Indianmulberry seed 1-2 part.
Described organic matter is animal fat and animal excrement.
Described slow-release fertilizer is composite fertilizer special and calcium superphosphate, and described composite fertilizer special and calcium superphosphate volume ratio are 1:1, and described composite fertilizer special is the fertilizer that contains nitrogen, phosphorus, potassium nutrition, and wherein the weight ratio of nitrogen, phosphorus, potassium is 1.5:1:1.
The beneficial effect that the present invention produces is that soil culture medium of the present invention can reduce the impact of heavy metal contamination on plant-growth, has stronger resistance to organic contamination, Salt And Alkali Tolerance, barren-resistant ability and nutrient acquisition capability; Substratum is slightly acidic state, is suitable for perching various microorganisms, can suppress the breeding of pathogenic bacteria, and wherein nettle grass and Root or stem of Littleleaf Indianmulberry are to have the plant that excess absorbs and accumulate the ability of heavy metal.
