Abstract

The invention discloses a urea formaldehyde sustained-release fertilizer special for tea. The fertilizer comprises raw materials including, by weight, 1-10 parts of starch, 20-50 parts of urea, 20-25 parts of formaldehyde, 50-100 parts of pig manure, 50-80 parts of cow bone powder, 30-100 parts of straw, 10-25 parts of sodium hypochlorite, 10-20 parts of copper sulfate, 10-20 parts of ferrous chloride, and 15-30 parts of composite probiotics. The invention also discloses a preparation method of the urea formaldehyde sustained-release fertilizer. According to the invention, through mixing organic fertilizer and urea formaldehyde fertilizer, the nutrition of the organic fertilizer and the sustained-release effect of the urea formaldehyde fertilizer are combined. Sodium hypochlorite is adopted as a stabilizing agent, such that fertilizer stability is improved, and the fertilizer sustained-release effect is further improved. Copper sulfate can act as an absorbing agent for absorbing moisture, and can also provide a basic mineral. The nutrition components of the formaldehyde sustained-release fertilizer provided by the invention are rich and comprehensive. The fertilizer can satisfy basic growth requirements of various crops.

Description

technical field [0001] The invention relates to a urea-formaldehyde fertilizer, in particular to a special urea-formaldehyde slow-release fertilizer for tea and a preparation method thereof. Background technique [0002] Organic fertilizers refer to fertilizers containing a large amount of organic substances obtained through microbial fermentation of natural organic matter. Most of this kind of fertilizer is made of plant straw, human and animal manure, green manure and various wastes, which are piled up on the spot and applied on the spot, so it is also called farm manure. It generally includes human excrement, barn manure, green manure, compost manure, cake manure, soil miscellaneous manure, separated species and various wastes and humic acid fertilizers. Urea-formaldehyde fertilizer is a fertilizer formed by the condensation of urea and formaldehyde. The current organic fertilizers have no slow-release effect, while urea-formaldehyde fertilizers lack natural biomass, whi...
