Introduction

The purpose of this standard is to regulate the granular pesticide or herbicide spreader test can be repeated standardized tests to graphs and tables the grid forms for the test results are described and compared.

Determine the type of granular pesticide or herbicide through tests, grain tank dose tablets, the amount of spreading and forward speed setpoint traffic, Flow uniformity and uniformity of.

Choice test (see Appendix B) allows the evaluation system is perfect.

Note. These tests can test and mount the spreader host binding conducted such a test called the combination test.

Into pieces, rows, or 3.1 point to spreading equipment defined granules into strips.

For mounting ancillary equipment (such as. granule spreader) of equipment (such as. Seeder).

Press the set flow rate, the granules discharged from the granulation tank and transported to the ground (such as. spreading into pieces or strips) or soil (eg. by conveying Tube into the seed trench) institutions.

Unit time Nei Sabu granules mass or volume.

Unit length per unit area or per point spreading granules of mass or volume.

Grain tank filled with granules of the total.

When determining grain tank capacity, on the surface of granules should be smooth. If there is no full tank mark or the manufacturer's instructions not described granules should GB/T 21157-2007/ISO 8524. 1986
