Spherical fertilizer

Abstract

The invention discloses a spherical fertilizer. The spherical fertilizer comprises the following components in parts by weight: 80-100 parts of urea, 40-50 parts of nitrates, 30-40 parts of phosphates, 20-40 parts of plant ash, 30-50 parts of potassium chloride, 20-40 parts of animal oil and fat and 10-30 parts of lysine. The spherical fertilizer has the beneficial effects that the spherical fertilizer is simple in proportioning, has long fertilizer efficiency time and is convenient and quick to apply; in particular, the spherical fertilizer is formed by melting the raw materials in a heating reaction kettle and then pouring the raw materials into a mould and demoulding the product after cooling; the diameter of the fertilizer is 5-8cm and during application, one fertilizer is placed every other 30-50cm; the fertilizer has great diameter and is agglomerated, thus greatly increasing the slow release time; compared with the previous small-granule fertilizers, the spherical fertilizer has the advantages that the fertilizer efficiency is increased by 75-85% and the fertilizer application speed is increased by 65-80%; the fertilizer application costs of farmers and the manufacturing costs of manufacturers are also greatly reduced.

Description

[0001] Technical field: [0002] The invention relates to the technical field of fertilizers, in particular to a spherical fertilizer. [0003] Background technique: [0004] In today's agricultural production, it is usually necessary to use fertilizers to increase agricultural production. During the fertilization process, it is necessary to use a spreader or fertilization equipment to spread the fertilizer after furrowing. Traditional fertilizers are all in the shape of fine particles, usually spherical particles with a size of 3-5mm. However, the traditional fertilizer particles are too small, especially when fertilizing by hand, it is difficult to control the amount, so fertilization is time-consuming and laborious. The fertilizer with too small particles has a small slow release degree and short fertilizer effect time. For this reason, there is a need for a spherical fertilizer with simple proportioning, long fertilizer effect time, and convenient and fast fertilizatio...
