Large fertilizer with longer fertilizer efficiency duration

Abstract

The invention discloses a large fertilizer with longer fertilizer efficiency duration. The large fertilizer comprises the following components in parts by weight: 80-100 parts of fermented chicken manure, 40-50 parts of modified starch, 30-40 parts of mixture of ground phosphate rock, zeolite powder and red stone powder in a mass ratio of 5 to 2 to 1, 20-40 parts of biogas residues, 30-50 parts of potassium sulfate, 20-40 parts of mixture of oil residues and bean cakes in a mass ratio of 1 to 3 and 10-30 parts of potassium fulvate. The large fertilizer is simple to prepare, has long fertilizer efficiency duration, is convenient and fast to apply and greatly increases the slow release time. Compared with previous small granular fertilizers, the large fertilizer has the advantages that the fertilizer efficiency is improved by 75-85% and the fertilizer application speed is increased by 65-80%, so that 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 bulk fertilizer with prolonged fertilizer efficiency. [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, need to occur a kind of proportioning simple, the fertilization time is long, the bulk fertilizer of a ...
