Embodiment 1

[0022] A fertilizer with soil remediation function prepared from the following raw materials: 45 parts of urea, 15 parts of potassium dihydrogen phosphate, 8 parts of phosphogypsum, 3 parts of calcium ammonium nitrate, 18 parts of modified diatomite, and 18 parts of polylactic acid fiber share. The average diameter of the polylactic acid fiber is 20-30nm, and the molecular weight of the polylactic acid fiber is 60000-100000.

[0023] The specific preparation method is as follows:

[0024] The preparation method of modified diatomite: yeast liquid is 20 parts by mass of starch, adding 1 part by mass of ammonium sulfate, adding 100 parts by mass of water, heating and dissolving, adjusting the pH value to 6-7, and inoculating Torulopsis glabrata Bacteria, the inoculum amount is 0.2%, and fermented, the fermentation temperature is maintained at 28-32°C, cultivated for 36-72 hours, filtered and washed, and mixed with diatomaceous earth evenly. The effective viable count of Torulo...

Abstract

The invention discloses a fertilizer with a soil remediation function. The fertilizer is prepared from the following raw materials: 40-50 parts of urea, 15-20 parts of monopotassium phosphate, 5-10 parts of ardealite, 3-5 parts of calcium ammonium nitrate, 15-18 parts of modified diatomite and 12-18 parts of polylactic acid fiber. The preparation method comprises the following steps: (1) stirringphosphogypsum, calcium ammonium nitrate and polylactic acid fibers for 40 minutes at 50-60 DEG C, then carrying out ball milling treatment, adding polyaspartic acid, stirring for 1 hour at 50 DEG C, and then drying and grinding into powder; and (2) uniformly mixing the powder with urea, monopotassium phosphate and modified diatomite, and granulating. The prepared fertilizer is high in dissolving speed and good in stability after being dissolved, soil can be effectively repaired, and the immunity of planted plants is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer with soil repair function and a preparation method thereof. Background technique [0002] Soil is the foundation of human production and life. With the development of modern industry and agriculture, harmful substances in soil are also increasing. Agricultural production activities on these polluted soils will inevitably cause food safety problems. Common forms of soil pollution include inorganic pollution and organic pollution, among which heavy metal element pollution is the most significant and harmful for inorganic pollution, and chemical fertilizers, pesticides, insecticides and herbicides are the most obvious and harmful for organic pollution. Cadmium ion is a relatively common heavy metal pollution. [0003] Cadmium (cadmium) is a silver-white toxic heavy metal with metallic luster. It is not an essential element for the human body. It mainly ...
