Problems solved by technology

Quick-acting fertilizers, especially quick-acting nitrogen fertilizers, exist in the soil in an ionic state, and they are easy to lose with irrigation water, which makes the fertilizer utilization rate low and the fertilization effect is poor
At present, there is a lack of new fertilizer varieties to solve the above problems

Abstract

The invention relates to a special controlled release fertilizer for foliage plant spathiphyllum florbundum and a preparing method thereof. The fertilizer is obtained by compounding modified epoxy resin coated urea with different coating amount, 5% modified epoxy resin coated compound fertilizer, 3% modified epoxy resin coated sulphate-potassium magnesium, diammonium nitrate, etc. The special controlled release fertilizer for spathiphyllum florbundum is applied during transplantation, has advantages of saving nitrogenous fertilizer consumption, improving fertilizer availability ratio, and satisfying request of nitrogen, phosphorus and kalium during different growth periods.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for modified epoxy resin-coated Hulk and a preparation method thereof, belonging to the technical field of slow / controlled-release fertilizers. Background technique [0002] Hulk is one of the most popular indoor foliage plants in Europe and America. It has large leaves, dark green leaves, dignified simplicity, strong shade tolerance, and is suitable for placement in many places indoors. In my country, the Hulk is even more popular in high-end hotels, exhibition halls, large conference rooms and other places. In recent years, with the improvement of the living conditions and the improvement of the quality of life of Chinese residents, more and more Hulk plants are grown at home. [0003] Hulk prefers fertilizer, but is not tolerant to fertilizer; Hulk's requirements for soil are loose, good water permeability and ventilation. This kind of soil has poor ability to retain nutrient ions, a...
