Leaf surface resistance and control agent for blocking heavy metal accumulation and preparation method thereof

Abstract

The invention discloses and provides a leaf surface resistance and control agent for blocking heavy metal accumulation and a preparation method thereof. The leaf surface resistance and control agent is prepared from the following components in parts by weight: 1-3 parts of borax, 5-9 parts of nano silicon dioxide, 10-17 parts of carbon nano tubes, 5-8 parts of a surfactant, 18-31 parts of tea seedcake, 7-9 parts of dunaliella, 13-22 parts of flammulina velutipes fungus chaff, 3-5 parts of betel nut tree sawdust, 9-13 parts of a microbial agent, 3-4.5 parts of orange peel powder, 8-13 parts ofdistillers' grains, 7-10 parts of artemisia apiacea leaves, 25-43 parts of tea saponin, 1-3 parts of citric acid, 12-28 parts of amino acids, 6-11 parts of humic acid and 1000-1500 parts of deionizedwater. The leaf surface resistance and control agent prepared from the raw materials can prevent plants from absorbing heavy metals in air and soil and prevent the heavy metals from damaging the plants. Meanwhile, according to the preparation method of the leaf surface resistance and control agent for blocking heavy metal accumulation, effective components in the raw materials can be fully utilized, and the method is easy to operate and beneficial to industrial promotion.

Description

technical field [0001] The invention relates to the technical field of foliar inhibitors and control agents, in particular to a foliage inhibitors and control agent for blocking the accumulation of heavy metals and a preparation method thereof. Background technique [0002] Heavy metal refers to the density greater than 4g / cm 3 Most of the metals in nature exist in the form of compounds. With the mining, smelting, processing and commercial manufacturing of heavy metals, a large number of heavy metal elements such as lead, cadmium, mercury, etc. enter the atmosphere, water or soil, causing serious heavy metal pollution. Pollution. Soil is an important basis for the growth of crops. Crops grow in high-concentration heavy metal soil for a long time, and their normal growth will be affected by heavy metals, and heavy metals will be enriched in crops, making crops themselves a source of heavy metal pollution. [0003] Heavy metals themselves are difficult to degrade, and it is ...

Problems solved by technology

Although the above methods have the advantages of thorough restoration and stability, they are huge in engineering volume, high in investment, and destroy soil structures. They are only suitable for the restoration and treatment of small areas of heavily polluted areas, and are not suitable for soil restoration of cultivated land.

In addition, bioremediation technology and joint restoration technology are the direction of future development, but for the current stage of cultivated land soil restoration, this method has a long cycle and slow effect, which will make the treated soil unable to plant crops for a long time. The utilization value of the bioremediation technology is affected, which in turn creates difficulties for the promotion of bioremediation technology
