Description
Technical Field
The invention relates to the technical field of soil remediation agents, and relates to a soil remediation agent with a pH adjusting effect and a preparation method thereof.
Background
Since the 60 th of the 20 th century, chemical fertilizers are gradually used for increasing the weight of soil in China, and are mainly processed by a plurality of chemical medicines such as ammonium sulfate, urea and the like, so that the effect of increasing the crop yield in a short period can be achieved, however, the long-term use of the chemical fertilizers for increasing the weight of the soil can not increase the crop yield, but can cause soil hardening, large accumulation of nitrate, imbalance of the proportion of nutrients, obstruction of the normal growth and development of crops, and reduction of the yield of the crops until the crops die.
By 2019, the cultivated land area of China is about 17.41 hundred million acres, however, due to geographical and climatic differences in the south and the north, pH acid and alkali polarization is caused, the soil in the north is over-alkalized, and the soil in the south is over-acidified. The traditional soil restoration agent only considers the supplement of soil organic matters and conventional major elements such as nitrogen, phosphorus and potassium, and the like, improves the soil environment to a certain extent, but the regulation of the pH of the plant is neglected by a plurality of products, and the supplement of various medium and trace elements which are lacked by the plant and soil beneficial bacteria which are beneficial to the growth of the plant is not paid sufficient attention.
Some recent patents disclose methods for adjusting the pH of soil. CN104045399B and CN102503728A use calcium cyanamide as a main pH regulator, and the pH of the acid soil is improved to a certain extent; CN105885868A discloses an efficient soil restoration agent and a preparation method thereof, wherein marine organism organic calcium, red mud, humic acid and the like are used for adjusting the pH value of soil, the cost is low, and heavy metal pollution is reduced to a certain extent; CN111269724 and CN110819357A use red mud and attapulgite to adjust pH, and particularly CN111269724 adopts chitosan to wrap a medicament, so that the chitosan is dissolved when the pH of soil is acidic, and the medicament is released to slowly release and adjust the pH; CN109517600A uses pH regulator of oxalic acid, citric acid, ferrous sulfate combination to regulate soil; CN110171999A is to regulate the alkaline soil by a series of fermented humic acid products; patent CN102946723A uses a part of pH dependent film forming polymer to coat seeds or plants against pests and adverse factors in soil. The method has a certain adjusting effect on over-acidified or alkalized soil, but various methods are almost biased to alkaline adjustment of acidified soil or acidic conditions of alkalized soil, have no universal adjusting effect on national soil pH, and most soil conditioners are used for adjusting soil in a large scale by using chemical preparations or industrial raw materials, so that secondary pollution is generated on the soil to a greater or lesser extent. Secondly, part of the raw materials adopted by many soil remediation agents are expensive and high in cost, so that the soil remediation cost is increased.
Therefore, the soil remediation agent which is friendly to soil, environment-friendly and low in cost is provided, the soil can be adjusted to be proper in pH value and various soil probiotics can be supplemented on the basis of supplementing soil organic matters and various medium and trace elements, secondary pollution to the soil is not generated, and the soil remediation agent is a problem which needs to be paid attention to in the field.
