Abstract

The invention relates to a long-acting controlled-release fertilizer special for Chinese angelica and a preparation method and application thereof. The fertilizer special for the Chinese angelica comprises urea, double superphosphate or diammonium phosphate, potassium sulfate, a fertilizer sustained release medicament and a secondary and micro-element, wherein the fertilizer sustained release medicament is N-acetyl-L-methionine (NAM); and the secondary and micro-element is one or a combination of Ca, Mg, S, Mn, Mo and Zn. The long-acting controlled-release fertilizer special for the Chinese angelica has the advantages of capability of overcoming the defects of low fertilizer utilization ratio, poor fertilizer efficiency durability, inconvenient application and the like existing in the prior art and realizing one-step fertilizer application in a Chinese angelica production process, convenient application, high fertilizer utilization ratio, high fertilizer efficiency durability and the like.

Description

technical field [0001] The invention relates to a compound fertilizer for agricultural production, in particular to a special fertilizer for long-acting slow-release angelica and its preparation method and application. Background technique [0002] In agricultural production, in order to cultivate soil fertility and promote sustainable agricultural production, it is often necessary to apply fertilizers, especially compound fertilizers. Compound fertilizer refers to a fertilizer containing two or more nutrients, such as compound fertilizer potassium dihydrogen phosphate and diammonium phosphorus. In order to improve the environmental quality, it is necessary to increase the utilization rate of fertilizers and give full play to the economic and environmental benefits of fertilizers. Special fertilizers with high concentration, multi-component compounding, high controllable release and high efficiency have become a hot spot in the research of special fertilizers for crops today...
