Embodiment 1

[0021] The preparation steps of the granular soil conditioner are as follows:

[0022] 1. Preparation of prolifera slag: (1) Pass prolifera powder (washed, dried and pulverized) through an 80-mesh sieve, add clean water according to a material-to-liquid ratio of 1:30, heat the reaction kettle to 60°C, extract for 2 hours, and then Separate and filter, respectively collect filtrate a and filter residue a; (2) take filter residue a and add clear water at a ratio of 1:10 material to liquid, then add 1‰ mixed enzymes (cellulase, pectinase), adjust the pH of the system to 4.0, and heat up. to 40° C., stirring for 1 hour, and centrifuging to obtain filtrate b and filter residue b; (3) combining filter residues a and b to obtain the slag of the present invention, which is for later use.

[0023] 2. Preparation of fish leftovers: (1) Take fish leftovers, pulverize them into pulp in a pulverizer, put them into a fermentation tank, and add water according to a material-to-liquid ratio o...

Abstract

The invention provides a preparation method of a granular soil regulator and aims to provide a fish leftover-based soil regulator which is convenient to use, low in cost and good in improving effect. The formula combination contains 50-80% of oyster shell powder, 10-30% of fish leftovers, 10-30% of enteromorpha residues and 0.5-5% of a microbial inoculant. Finally, the obtained soil regulator is granular.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a preparation method of a soil conditioner. Background technique [0002] Soil acidification refers to the acceptance of H + After that, on the one hand, H+ reacts with the base cations on the soil colloid and is adsorbed on the surface of the soil particles, and the exchanged base cations are leached with the seepage water; on the other hand, the H+ on the surface of the soil particles + It also spontaneously reacts with aluminum on the surface of the mineral lattice and is rapidly converted into exchangeable aluminum. As a result, soil basic cations decreased, hydrogen and aluminum ions increased, soil pH decreased, and the activity of toxic metal ions increased. There are natural factors and man-made factors that cause soil acidification, but natural acidification is very slow. Studies have shown that human factors greatly accelerate soil acidification. Among the human f...
