Preparation method of fertilizer special for rice and capable of reducing labor cost

Abstract

The invention discloses a preparation method of fertilizer special for rice and capable of reducing the labor cost. The method includes the following steps of stirring ammonium chloride, chitosan, water and paraffin, adding formaldehyde in a stirring state, continuing stirring, adding absolute ethyl alcohol, adjusting the pH value of a system and carrying out filtering and washing to obtain a first material; stirring the first material, ammonium nitrate, ammonium bicarbonate, triple superphosphate, montmorillonoid, calcined kaolin, expanded perlite, borax and coal gangue, conveying the mixtureto a fusion tank for heating and stirring, raising the temperature, continuing stirring and conducting filtering to obtain a second material; mixing manioc dregs, shrimp head meal, distillers' grains, mushroom dregs, royal jelly, zinc humate and 6-urea iron trinitrate, adding water, conducting grinding, raising the temperature, adding the second material for even blending to obtain slurry, and conveying the slurry into a rotary slurry spraying machine, wherein a slurry spraying port of the rotary slurry spraying machine is positioned above a drying tower, the slurry is sprayed into fertilizerliquid drops above the drying tower from the slurry spraying port of the rotary slurry spraying machine, and the slurry subsides and is dried in the drying tower to obtain the granular fertilizer special for the rice.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing rice-specific fertilizers with reduced labor costs. Background technique [0002] In the process of rice planting, the demand for nutrients is extremely high, and the frequency of fertilization with ordinary fertilizers is high, and the labor intensity is high. According to the general fertilization habits, an appropriate amount of base fertilizer is applied before the paddy field is raked, and topdressing is required when the rice field becomes green and lodging; throwing seedlings or transplanting After 5-7 days of planting, topdressing of tillering fertilizer is required, and multiple times of fertilizer is required for one season of rice, which is time-consuming and laborious, which not only pollutes the breeding environment, but also has high costs. Contents of the invention [0003] Based on the technical problems existing in the background tech...
