Embodiment 1
[0052] Embodiment one: the specific formula of the present invention is as follows (content is the enzyme activity of composition): cellulase 10000u / g, sucrase 1000mg / g, catalase 2000mg / g, soil protease 500 μ g / g, soil phosphatase 500mg / g g.
[0053] Preparation method: After filtering, purifying and concentrating the liquid raw material enzymes, granulate them with a solid granulator, then crush and granulate the solid raw material enzymes, and then use the single enzyme preparation that has been granulated according to the enzyme activity requirements. The solid mixer is mixed and compounded, and then quantitatively packaged to become a product.
[0054] Application method: mix 500g of the enzyme preparation composition of the present invention with 20kg of organic fertilizer and evenly fertilize to 666.7m 2 On the soil, and plow more than 15cm deep.
Embodiment 2
[0055] Embodiment two: the specific formula of the present invention is as follows (content is the enzyme activity of composition): cellulase 50000u / g, sucrase 3000mg / g, catalase 10000mg / g, soil protease 1000 μ g / g, soil phosphatase 1000mg / g g.
[0056] The preparation method is the same as in Example 1.
[0057] Application method: mix 500g of the enzyme preparation composition of the present invention with 20kg of inorganic fertilizer and evenly fertilize to 666.7m 2 On the soil, and plow more than 15cm deep.
Embodiment 3
[0058] Embodiment three: the specific formula of the present invention is as follows (content is the enzyme activity of composition): cellulase 25000u / g, sucrase 1500mg / g, catalase 5000mg / g, soil protease 750 μ g / g, soil phosphatase 750mg / g g.
[0059] The preparation method is the same as in Example 1.
[0060] Application method: mix 500g of the enzyme preparation composition of the present invention with 20kg of straw and apply fertilizer evenly to 666.7m 2 On the soil, and plow more than 15cm deep.

Abstract
The invention aims to provide an enzyme preparation composition for improving the fertility of soil, and its applications. The enzyme preparation composition is added to fully and accurately decompose organic fertilizers and plant straws to improve the contents of active organic matters in the soil so as to reach soil fertility and sol quality improvement purposes. The enzyme preparation composition provided by the invention can be applied after mixed with the organic fertilizers, inorganic fertilizers and the straws, and can also be sprayed on the surfaces of the organic fertilizers or the straws after dissolved in water with a ratio of the enzyme preparation composition to water being 1:9. The enzyme preparation composition is characterized in that the enzyme preparation composition comprises the components, by enzyme activity, 10000-50000mu/g of cellulase (QB 2583-2003, filter paper activity (FPA)), 1000-3000mg/g of sucrase (3,5-dinitrosalicylic acid colorimetry), 2000-10000mg/g of catalase (potassium permanganate titration method), 500-1000ug/g of soil protease (rancTRH method) and 500-1000mg/g of soil phosphatase (disodium phenyl phosphate colorimetry).
Description
Technical field: [0001] The invention belongs to the technical field of biological enzymes, in particular to an enzyme composition for improving soil fertility and its application. Background technique: [0002] Soil fertility mainly depends on the application of organic fertilizers. The proportion of organic fertilizers in the total amount of fertilizers decreased from 32.1% in 1995 to 30.6% in 2000, and fell to less than 25% in 2007. It can be seen that the proportion of organic fertilizers The application rate is gradually decreasing. However, organic fertilizers also have low nutrient content, are not easy to decompose, and cannot meet the requirements of high crop yield in time. [0003] The amount of inorganic fertilizer used in my country was 41.24 million tons in 1990, 44.11 million tons in 2003, and 51.07 million tons in 2007. From the above data, it can be seen that the amount of inorganic fertilizer used is increasing rapidly. Inorganic fertilizers provide carbo...
