Introduction

Organic manure manure (fermented fertilizer) and granular fertilizer are important fertilizer sources for agricultural production. It plays an important role in soil construction, increasing crop yield and improving quality. Organic fertilizer is an "environmentally friendly fertilizer" that meets the requirements of the times. Water, save water, reduce water loss and evaporation, reduce the effect of drought, reduce fertilizer application, reduce salinity damage, condition soil, stimulate The active rate of microorganisms in living soil can also overcome soil compaction, increase soil air permeability, and reduce land degradation and soil erosion caused by chemical fertilizers. It can effectively promote plant growth and form high-standard farmland. GB/T 20346 aims to establish technical standards for the production and use of fertilizing machinery, Consists of two parts. --- Part 1.Full width fertilizer spreaders. The purpose is to provide technical basis for the design and manufacture of full width fertilizer spreader. --- Part 2.Fertilizers between rows. The purpose is to provide technical basis for the design and manufacture of interrow fertilizer applicator. Fertilizer applicators part 2.interrow applicators

1 Scope
