Preparation method of special fertilizer for mat grass for improving soil hardening

Abstract

The invention discloses a preparation method of a special fertilizer for mat grass for improving soil hardening. The preparation method comprises the following steps: mixing ammonium molybdate, lightcalcium carbonate, quartz sand, manganese sulfate and diaminoferric xanthohumate, adding water and uniformly stirring the materials to obtain a first prefabricated material; uniformly mixing waste oilresidues, pigeon dung and chrysanthemum meal, and adding an EM bacterial agent for fermentation to obtain a second prefabricated material; adding the first prefabricated material, saturated ammonia water, ferric ammonium phosphate, a defluorinated phosphate fertilizer and a kiln ash potash fertilizer into the second prefabricated material, carrying out uniform mixing and granulating, spraying ananti-caking agent for coating to obtain the special fertilizer for the mat grass for improving soil hardening. The anti-caking agent is prepared by the following processes: mixing keratin, polymaleicacid, polyvinyl alcohol and water, heating and stirring the mixture, heating the mixture again, continuously stirring the mixture, carrying out spray drying, adding talcum powder and cyclodextrin, andstirring the mixture uniformly to obtain the anti-caking agent.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing a special fertilizer for mat grass that improves soil compaction. Background technique [0002] Mat grass is a perennial swamp herbaceous plant with many types, including rush grass, asparagus, cattail grass, etc. The mat grass cultivated in Hengshan County belongs to the rush family and a variety of rush grass species. It has a cultivation history of more than 200 years . [0003] At present, since mat grass was introduced, there has been little research on mat grass cultivation technology, and no one cares about the research on high-quality and high-yield technology. At present, ordinary chemical fertilizers are often used in the field to increase the yield of mat grass. Although the effect is quick, it is easy to cause compaction of the soil, pollute the environment, and affect the subsequent planting of late rice. Contents of the invention [00...
