GB/T 9478-2005 in English

《GB/T 9478-2005谷物条播机 试验方法》由TC201（全国农业机械标准化技术委员会）归口，TC201SC5（全国农业机械标准化技术委员会耕种和施肥机械分会）执行，主管部门为中国机械工业联合会。
本标准规定了谷物条播机的试验方法，包括挂接在主机上的条播机。本试验方法可用于复验试验性能的测定，因此可获得涉及下述各影响因素时的数值的图表的比较结果:――种子类型；――前进速度；――种子箱中种子(肥料)面的高度；――播量调节；――地面坡度；――地表状况(颠簸)。选择试验(见附录B)可增补对采用处理后种子播种效果和施肥效果的试验方法。规定性试验没有给出播种现场种子分布的真实情况。

Scope

This standard specifies the test methods for grain drills, including drills attached to the host. This test method can be used for the determination of the performance of the re-inspection test, so the comparison results of the numerical values and graphs can be obtained when the following influencing factors are involved: ----seed type; ----forward speed: ----seed box The height of the medium seed (fertilizer) surface; ---- sowing rate adjustment; ---- ground slope; ---- ground surface conditions (bumps). Selective test (see Appendix B) can be added to the test method of seed sowing effect and fertilization effect after treatment. Prescriptive tests do not give a true picture of the distribution of seeds at the planting site.
