Preparation technology of organic fertilizer for crop

Abstract

The invention discloses a preparation technology of an organic fertilizer for a crop. The technology comprises the steps of (1) blending the following components in parts by weight: 11.5 parts of EM (Effective Microorganism), 27 parts of kelp residue, 32 parts of shell powder, 26 parts of saccharified residue, 38 parts of diatom ooze and 41 parts of water, and (2) performing stirring in a sealed tank at 50 DEG C, performing fermentation for 50-80 days, performing drying at 70 DEG C, performing crushing with a pelletizer and then performing subpackaging. The preparation technology of the organic fertilizer for the crop can overcome the defects of unreasonable ratio, poor environmental protection property, poor use effect and the like in the prior art to realize the advantages of reasonable ratio, good environmental protection property and good use effect.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a preparation process of an organic fertilizer for crops. Background technique [0002] Refers to various plants cultivated in agriculture. Including food crops and economic crops (oil crops, vegetable crops, flowers, grass, trees) two categories. Edible crops are one of the sources of basic human food. Food self-sufficiency is the foundation of a country's sustainable development. The growth of crops is inseparable from scientific and technological production technologies, as well as machinery and equipment manufactured by new industries that can assist agricultural production. [0003] The crops absorb nutrients mainly rely on the root system, and the root hair area about 1 cm away from the root tip is the most active area for absorbing nutrients. Roots absorb nutrients mainly through mass flow and diffusion. Mass flow refers to the water transpiration of crops, so t...
