Abstract

The invention discloses peucedanum praeruptorum dunn stable slow-release special-purpose fertilizer and a preparation method thereof. The peucedanum praeruptorum dunn stable slow-release special-purpose fertilizer is prepared from 6-10 parts by weight of urea, 54-60 parts by weight of calcium superphosphate, 10-14 parts by weight of potassium sulfate, a synergist and an additive by mixing granulation. In preparation, a rotor drum granulator is used for granulation. The whole production system comprises processes of material feeding, material blending, granulation, drying, screening and material-return, finished product cooling, packaging and tail gas treatment. The preparation method realizes coordination of stable (long-acting slow-release) special-purpose fertilizer release characteristics and peucedanum praeruptorum dunn nutrient absorption, improves a fertilizer efficiency period and a fertilizer utilization rate, balances nutrient feeding, reduces fertilizer loss, and realizes environmental protection. Through use of the peucedanum praeruptorum dunn stable slow-release special-purpose fertilizer, a peucedanum praeruptorum dunn yield is obviously improved, peucedanum praeruptorum dunn production one-step fertilization light and simple cultivation is realized, peucedanum praeruptorum dunn production labor investment is reduced and peasant income is improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a stable (long-acting slow-release type) special fertilizer and a preparation method thereof. Background technique [0002] Peucedanum praeruptum Dunn, a traditional Chinese medicine, is a perennial herbaceous plant of Umbelliferae. , Yanfeng, Nanshifangfeng, Podishifangfeng, Jijiaoqianhu, and Yanchuanxiong. The roots are used as medicines, which have the effects of dispelling wind and cooling, relieving cough and eliminating phlegm, and are the only source of traditional Chinese medicine Qianhu. [0003] Guizhou is one of the main production areas of Qianhu, and it is distributed throughout the province. The root of Peucedanum baicalensis produced in Guizhou Province is thick, with few branches, soft texture, sweet but bitter taste, and strong aroma. It is very popular in the market and has a certain influence in major drug markets across the country. At present, my country's annual...
