Introduction

This document is modified using ISO 5690-1:1985: The release and implementation of this document has promoted the use and development of fertilization machinery in my country: organic

Fertilizer manure (fermented fertilizer) and granular fertilizer are important fertilizer sources for agricultural production:

It plays an important role in improving crop yield and quality: Organic fertilizer is an "environmentally friendly fertilizer" organic fertilizer that meets the requirements of the times:

Water, save water, reduce water loss and evaporation, reduce the effect of drought, can reduce fertilizer application, reduce salinity damage, soil conditioning, stimulate

The active rate of microorganisms in living soil can also overcome soil compaction and increase soil air permeability: Reduce land degradation due to fertilizers, slabs

It is of great significance to effectively promote plant growth and form high-standard farmland: According to the characteristics of field fertilization machinery, this series of fertilization

The Fertilizer Machinery document is divided into the following two parts:

--- Fertilization Machinery Part 1: Full-width Fertilizer Spreaders;

--- Fertilizers Part 2: Fertilizers between rows:

This document is the first part of a series of standards: This document provides the technical basis for the design and manufacture of full-width fertilizer spreaders:

Obtain the technical indicators and performance parameters of the fertilizer spreader in the form of text description or chart, and provide technical support for the trade and quality management of the fertilizer spreader:
