Soil pesticide residue adsorbent

Abstract

The invention discloses a soil pesticide residue adsorbent, and relates to the technical field of agriculture. The soil pesticide residue adsorbent is prepared from the following components in parts by weight: 280-350 parts of oyster shell powder, 280-350 parts of attapulgite clay, 80-150 parts of wooden activated carbon, 5-20 parts of biological flavone, 1-5 parts of biological enzyme, 1-5 parts of mineral fulvic acid, 1-5 parts of resin adhesive, 1-5 parts of biological bacteria, 180-220 parts of magnesium sulfate, 40-60 parts of calcium oxide, 8-20 parts of boric acid and 8-20 parts of zinc sulfate. The soil pesticide residue adsorbent disclosed by the invention is rich in various macroelements and microelements required by plants, can exchange various metal ions, improve soil, reduce the content of heavy metals such as cadmium in the soil, repair and improve diseased cultivated land fed with chemical fertilizers and restore the ecological environment of the soil; and residues of pesticides, chemical fertilizers and heavy metals are reduced and degraded, the safety of grains, fruits and vegetables is guaranteed, the health index of Chinese people is improved, and diseases are reduced.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a soil pesticide residue adsorbent. Background technique [0002] Prospering agriculture through science and technology is the fundamental path for my country's agricultural development. Land is the lifeblood of agriculture. The eight-character agricultural constitution puts "soil" first, revealing the scientific development concept based on soil. Good soil can produce more grain. However, at present, my country's cultivated land is seriously polluted, resulting in the accumulation of acidic and toxic substances remaining in the cultivated soil, and the damage to the root system of crops is becoming more and more serious. Soil acidification is the main reason for the high incidence and low cure rate of crops; more It is the main cause of the disintegration of the soil aggregate structure, solidification and compaction, thinning of the plow layer, hard plow bottom layer, airtig...

AI Technical Summary

Problems solved by technology

Pesticide residues can cause the following hazards: Affect health: Long-term consumption of agricultural by-products with excessive pesticide residues may not cause acute poisoning, but may cause chronic poisoning in humans and animals, leading to disease, and even affect the next generation; Agriculture: Due to the irrational use of pesticides, especially herbicides, frequent chemical injury accidents often lead to large-scale production reductions or even extinctions, seriously affecting agricultural production; affecting trade: countries around the world, especially developed countries, attach great importance to the issue of pesticide residues , more and more stringent limit standards have been set for pesticide residues in various agricultural and sideline products

[0004] 2. Chemical fertilizer pollution: chemical fertilizer is an important agricultural material, which has played a great role in increasing crop yield

First of all, from the perspective of the impact on soil physical properties, the application of chemical fertilizers alone will lead to deterioration of soil structure, increase in bulk density, and decrease in porosity; secondly, the application of chemical fertilizers may slow down or even decrease the rate of increase in soil organic matter, and the content of some nutrients is relatively low Or the imbalance between nutrients is not conducive to the development of soil fertility. Especially with the large-scale application of nitrogen, phosphorus and potassium, it also greatly consumes the beneficial substances in the soil, and the organic matter is destroyed by a large amount of nitrogen fertilizer. Because the soil physical and chemical indicators carbon The nitrogen ratio is 25 / 1, and 25 parts of carbon will be destroyed and consumed if one part of nitrogen enters the soil. Therefore, it is said that nitrogen fertilizer is the culprit of destroying the soil ecological environment. Chlorine in potassium fertilizer will also accelerate the disintegration of soil aggregate structure and cause Chlorine poisoning of fruit trees, melons, and potatoes affects quality and yield; thirdly, applying chemical fertilizers alone will lead to a decrease in the number of beneficial microorganisms in the soil or even the total amount of microorganisms; finally, because some chemical fertilizers contain polluting ingredients, excessive application (especially phosphate fertilizer) will pollute the soil accordingly
