Paddy field mineral trace element soil conditioner formula and use method thereof

Abstract

The present invention relates to a paddy field mineral trace element soil conditioner formula and a use method. The paddy field mineral trace element soil conditioner comprises the following raw materials: a trace-element-rich mineral fertilizer, a soil conditioning agent, lime and a leaf surface blocking agent, wherein the trace-element-rich mineral fertilizer comprises more than 50 medium traceelements and rare earth elements, the content of oxides silicon, calcium, manganese, iron, magnesium, sodium, aluminum and titanium is 50% or more, and the content of beneficial rare earth elements and trace elements lanthanum, strontium, zinc, selenium, boron, barium, gallium and nickel is larger than or equal to 2500 [mu]g/g. The soil conditioner is rich in medium trace elements silicon, calcium, magnesium, molybdenum, iron, copper, zinc and the like, the pH value is 10.0-12.0, and the soil conditioner comprises the following main components in percentage by weight: more than or equal to 20.0 percent of effective calcium (CaO), more than or equal to 12.0 percent of effective magnesium (MgO) and more than or equal to 12.0 percent of effective silicon (SiO2). According to the formula and the using method of the mineral trace element soil conditioner for the paddy field, mineral fertilizer is applied, and the mineral fertilizer is rich in various trace elements and is a main component of coenzymes in plants, so that cell tissues of injured parts are effectively repaired, and the injured parts are promoted to recover physiological functions as soon as possible to grow healthily.

Description

technical field [0001] The invention relates to the technical field of paddy field treatment, in particular to a formula of a paddy field mineral trace element soil conditioner and a use method. Background technique [0002] Existing mainstream soil remediation technologies such as guest-soil method, chemical leaching, thermal desorption, etc., in addition to high costs, will cause damage to the ecological environment of farmland soil microorganisms, and the gains outweigh the losses. At the same time, agricultural production will be interrupted, which is difficult to be accepted by farmers. These methods are mainly used in engineering restoration of industrial and mining sites. Currently, phytoremediation and microbial remediation technologies that are most suitable for farmland restoration have some insurmountable problems in practice. Although phytoremediation has low soil damage and low cost, it needs to occupy farmland for one to two years and is difficult to be accepte...

Problems solved by technology

[0002] Existing mainstream soil remediation technologies such as guest-soil method, chemical leaching, thermal desorption, etc., in addition to high costs, will cause damage to the ecological environment of farmland soil microorganisms, and the gains outweigh the losses

At the same time, it will interrupt agricultural production, which is difficult for farmers to accept. These methods are mainly used in engineering restoration of industrial and mining sites

Currently, phytoremediation and microbial remediation technologies that are most suitable for farmland restoration have some insurmountable problems in practice. Although phytoremediation has low soil damage and low cost, it needs to occupy farmland for one to two years and is difficult to be accepted by farmers; The problem with microbial remediation is that microorganisms that act on the degradation of heavy metals are difficult to survive in more acidic soils

Simple acid-base adjustment and soil conditioner can reduce the absorption of heavy metal ions by plants, but it will also cause damage to plants and reduce production
