Abstract

The invention discloses a preparation method of a slow-release fertilizer with a high fertilizer utilization rate for lotus root. The preparation method comprises the following steps: uniformly mixingSpan and Tween, adding olive oil to be stirred, adding egg white, glutaraldehyde and berberine hydrochloride, raising the temperature and stirring, demulsifying, performing water-oil phase separation, washing, performing freeze drying, adding talcum powder and cyclodextrin, and uniformly mixing to obtain a first material; adding fermented compound bacteria into water to be uniformly mixed, addingchicken manure, oil-tea-cake, straw powder, shrimp shell meal, coal gangue, rice chaff and protein paste to be uniformly mixed, and performing stacking fermentation to obtain a second material; adding ammonium nitrate, ammonium sulfate, defluorinated phosphate fertilizer, sylvinite, flue ash potash fertilizer, EDTA (Ethylene Diamine Tetraacetic Acid) chelated calcium, EDTA chelated zinc, EDTA chelated manganese and EDTA chelated copper into the second material to be uniformly mixed, pelletizing, spraying the first material for coating, and drying, thereby obtaining the slow-release fertilizerwith the high fertilizer utilization rate for lotus root.

Description

technical field [0001] The invention relates to the field of fertilizer technology, in particular to a method for preparing slow-release fertilizer for lotus root with high fertilizer utilization rate. Background technique [0002] Our country has the habit of cultivating lotus root since ancient times. Lotus root is rich in nutrition and delicious, and it is one of the must-have vegetables for Chinese people during the Spring Festival. Lotus root can not only be eaten fresh, but also processed into lotus root powder, sugared lotus root slices, etc.; lotus seeds can be used as soup, which is a natural tonic; In the past, lotus roots were mainly planted in ponds. In recent years, seedling field lotus root has been developed in rice producing areas, which further expands the cultivation area of ​​lotus root. [0003] The lotus root grows underwater, which brings a lot of inconvenience to fertilization management. Mechanized operation is difficult, and manual operation is ti...
