Problems solved by technology

For example: as a protein, an enzyme needs a certain amount of heavy metal ions as prosthetic groups. At this time, the addition of heavy metals can promote the coordination between the enzyme active center and the substrate, so that the enzyme molecule and its active center maintain a certain obligatory structure, changing The balanced nature of the enzyme-catalyzed reaction and the surface charge of the enzyme protein can fix heavy metal ions; another example: excessive heavy metals occupy the active center of the enzyme, or combine with the sulfhydryl, amine and carboxyl groups of the enzyme molecule, although the enzyme activity will decrease.
But for heavy metals, there are non-quantified consumption and fixed inhibition

Embodiment 3

[0064] Application of embodiment 3 soil enzyme activity synergist in soil conditioning

[0065] The soil enzyme activity synergist prepared by the method of Example 1 of the present invention is respectively planted in Mangshan tea tree in Hunan, tobacco planted in Ningxiang, Hunan, and rice planted in Qiongzhong, Hainan, and the same equal amount of fertilization method is used as soil enzyme respectively. Active synergist treatment and blank contrast, two kinds of application methods are compared, and specific measure is to carry out soil sampling respectively after harvesting crops in 3 areas, wherein, each area sampling point is 20, and each sampling point The weight of the sample is 3kg, and the sample will be sent to the Soil and Fertilizer Station Committee for inspection after the sample is divided. See the following table 1 for the effect of soil enzyme activity synergist on crop area soil conditioning:

[0066] The effect of table 1 soil enzyme activity synergist on...

Abstract

The invention discloses a preparation method of a soil enzyme activity synergist, a product and its application. The preparation method comprises the following steps: firstly hydrolyzing soybean meal by the use of an enzyme expansion solution for soybean meal hydrolysis to obtain a hydrolysate containing active free amino acid, adding fulvic acid, and carrying out spray drying to obtain an active soil enzyme-containing carrier containing 32-35% of water; and mixing the active soil enzyme-containing carrier and soil enzyme, and packaging so as to obtain the soil enzyme activity synergist. By the soil enzyme activity synergist, cracking and degradation of soil organic matter can be raised. It can be known through practice that utilization rate of soil organic matter is raised by 0.4-0.95%. Thus, soil structure can be improved, formation of a granular structure is remarkably promoted, soil fertility and soil moisture content can be regulated, and yield and quality of crops can be enhanced. What is important is that the soil enzyme activity synergist can inhibit pollution of heavy metal in soil.

Description

technical field [0001] The invention relates to a soil enzyme activity synergist and a preparation method thereof, in particular to a method for improving the cracking and degradation of soil organic matter, promoting the formation of soil aggregate structure, improving crop yield and quality, regulating soil fertility and soil moisture, and inhibiting A soil enzyme activity synergist composed of various soil enzymes polluted by heavy metals and a preparation method thereof. The invention belongs to the technical field of resource-saving and environment-friendly products and soil synergistic conditioners. Background technique [0002] According to the two types of products currently advocated, further specific requirements are put forward for improving the activity of cultivated land, preventing and controlling the pollution of cultivated land, and treating heavy metals. In order to implement the "Action Plan for Zero Growth in Chemical Fertilizer Use by 2020" issued by the...
