Problems solved by technology

The raw material of the fertilizer in this invention is mainly thermoplastic resin coating fertilizer. This coating material has good controlled release performance of nutrients, but is poorly sensitive to temperature changes. The speed of nutrients may lag; secondly, although the fertilizer effect period is longer than that of quick-acting fertilizers, it still needs to be applied once a year

Embodiment Construction

[0009] Technical scheme of the present invention is as follows:

[0010] A kind of long-acting fertilizer for landscaping seedlings, the mass parts of raw material components are as follows:

[0011] Sulfur plus polymer coated urea 50-100 parts,

[0012] 8% thermoplastic and thermosetting double-coated urea 150-200 parts,

[0013] 10% recycled thermoplastic resin coated urea 280-320 parts,

[0014] 150-200 parts of urea base coat 5% modified epoxy resin coating diammonium phosphate,

[0015] 150-190 parts of potassium nitrate coated with 5% modified epoxy resin coating of urea primer,

[0016] Diammonium phosphate 80-120 parts.

[0017] The sulfur-added polymer-coated urea is prepared by using granular urea as the core fertilizer, firstly spraying the inner cladding sulfur film, and then spraying the outer cladding polymer film. Wherein, the mass percentage of the sulfur film material in the core fertilizer is 18% to 22%, and the mass percentage of the high molecular poly...

Abstract

The invention relates to a sustained-release fertilizer for nursery stocks in landscaping and preparation and application. Raw materials are selected from different types of controlled release fertilizers: sulfur macromolecular polymer coated urea, 8 percent thermoplastic and thermosetting double-layer coated urea, 10 percent recycled thermoplastic resin coated urea, urea priming coat 5 percent modified epoxy resin coated diammonium phosphate, urea priming coat 5 percent modified epoxy resin coated potassium nitrate and diammonium phosphate. The sustained-release fertilizer for the afforesting nursery stocks is prepared through the formulation of various coated fertilizer raw materials according to nutrient release regularities of the raw materials in soil. The sustained-release fertilizer can be applied to a planting hole at one time in the transplanting process, and the sustained-release fertilizer has the advantages of no harm to a root system, 2 to 3-year useful life, high utilization rate and labor saving.

Description

technical field [0001] The invention relates to a long-acting fertilizer, in particular to a long-acting fertilizer for landscaping seedlings that does not damage the root system and has a long fertilizer effect time, and a preparation method and application thereof, belonging to the technical field of fertilizer production. Background technique [0002] With the development of the city and the increasing industrialization and modernization, especially the "three wastes" pollution of industrial and mining enterprises have seriously damaged the living environment and threatened the physical and mental health of residents. Introducing forests into cities and letting forests play their ecological functions to improve the increasingly serious environmental pollution in cities is an important aspect of improving urban living environment and people's living conditions. However, there is a gap between the development of urban gardens in China and the needs of the people. According ...
