Liquid biological humic acid soil repairing agent and its preparation and application methods

Abstract

The invention discloses a liquid biological humic acid soil repairing agent and its preparation and application methods. The liquid biological humic acid soil repairing agent comprises the following components: by weight, 48-64% of cane molasses, 26-38% of humic acid and 8-15% of beneficial bacteria. According to the invention, cane molasses produced in sugar industry is utilized, and a beneficial organism and humic acid are added. The above three components undergo fermentation so as to produce the liquid biological humic acid soil repairing agent which is used for watering, foliage spray or drop irrigation. By the adoption of the liquid biological humic acid soil repairing agent, soils can be restored and purified, plant diseases and insect pests are minimized, yield of crops is raised, and crop quality is improved. In addition, production technology is simple and production cost is low.

Description

technical field [0001] The invention relates to soil remediation technology, in particular to liquid biological humic acid soil remediation agent and its preparation and use method. Background technique [0002] Soil is an important material basis for human social production activities. However, with the acceleration of economic development and urbanization, soil pollution is very serious. It is estimated that nearly 1 / 5 of China's existing cultivated land is polluted to varying degrees, and polluted soil will Lead to crop yield reduction, and may even cause pollutants in agricultural products to exceed the standard, thereby endangering human health. Therefore, we must attach great importance to the prevention of soil pollution and the remediation of contaminated soil. [0003] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing its concentration to an acceptable level, o...
