Inorganic composite soil conditioner

Abstract

The invention discloses an inorganic composite soil conditioner. The inorganic composite soil conditioner comprises the following raw materials in parts by weight: 10 to 15 parts of fulvic acid, 20 to25 parts of urea, 5 to 8 parts of amino acid, 5 to 10 parts of lime, 10 to 15 parts of calcium magnesia phosphate fertilizer, 8 to 12 parts of a trace element, 3 to 6 parts of nucleotide, 5 to 10 parts of plant acid, 3 to 7 parts of a microbial agent, 2 to 5 parts of calcium superphosphate, and 1 to 4 parts of a water-retaining agent. The inorganic composite soil conditioner contains rich raw materials, such as the fulvic acid, urea, calcium magnesia phosphate fertilizer, calcium superphosphate, nucleotide and plant acid, is a soil conditioner, can further serve as fertilizer to be applied, is beneficial to improvement of soil property and soil fertility, adsorption and fixing of heavy metal ion in soil and reduction of soil bulk density, improves the cation exchange capacity of the soil,can further supplement heavy metal elements insufficient in the soil and improve soil organic matter, is beneficial to the growth of plant, contains more effective components, and is easy to be dissolved in water, fast to decompose and easy to absorb.

Description

technical field [0001] The invention belongs to the technical field of land improvement, and more specifically relates to an inorganic composite soil improver. Background technique [0002] Soil improvement is the process of taking corresponding physical, chemical or biological measures to improve soil properties, soil fertility, crop production, and the soil environment for human survival in response to the poor texture and structure of the soil. At present, with the rapid development of industrialization and urbanization in our country, many factors such as improper treatment and large discharge of pollutants, continuous application of chemical fertilizers, pesticides and insecticides, and irrational use of land have led to serious soil degradation. The hardening and pollution of the soil will reduce the productivity of the soil and the crop yield and quality, which not only bury hidden dangers for the safety of the crops, but also pollute the water quality and the environ...

At present, with the rapid development of industrialization and urbanization in our country, many factors such as improper treatment and large discharge of pollutants, continuous application of chemical fertilizers, pesticides and insecticides, and irrational use of land have led to serious soil degradation. The hardening and pollution of the soil will reduce the productivity of the soil and the crop yield and quality, which not only bury hidden dangers for the safety of the crops, but also pollute the water quality and the environment, and make the crops absorb heavy metals continuously during the growth process, and heavy metals Can endanger human health through the food chain
