摘　　要：目的研究不同扦样方案对粮食品质检验工作的影响,制定适合于当前我国储粮形式的扦样方案。方法本研究以吉林、河南、辽宁、安徽等省份的小麦和玉米储备仓为实验仓,采用不同的粮食扦样器、扦样方案进行扦样,随后对所扦样品进行质量指标、储藏品质指标以及卫生指标的测定,其中仓型涉及浅圆仓、房式仓以及立筒仓。结果研究结果显示所使用电动吸入式扦样器杂质含量略高于套管式扦样器,但数据差异性并不显著(P>0.05)。所制定扦样方案中的分区设置检验单位、不同扦样顺序、点样比例对粮食品质指标的检验也没有显著性差异(P>0.05)。结论通过对不同省份、不同储备粮种、多种仓型的实仓扦样实验,结果表明所采用的现代化扦样工具、优化的扦样方案并不会影响扦样样品的检验结果,所获得的扦样数据有望为未来制定更加适合我国粮仓的扦样方案提供支撑。Objective To study the impact of different sampling programs on grain quality inspection,and formulate a sampling program suitable for the current form of grain storage in China.Methods In this study,rice,wheat and maize reserve storages in Jilin,Henan,Liaoning and Anhui Provinces were used as experimental storages.The grain reserve storages involved shallow-circular storehouse,horizontal warehouses and vertical silos,and different grain samplers and sampling protocols were used to take the samples,followed by the determination of quality inspection,storage quality and health indexes of the taken samples.Results The results of the study showed that the impurity content in grain collected by electric suction was marginally higher than the casing grain sampler,however,the data variability was not significant(P>0.05).There was also no significant difference(P>0.05)in the test of grain quality indexes between the developed sampling program of setting up inspection units in the reserve storages,different sampling order,and different ratio of point sample.Conclusion Through the experiments on different provinces,different reserve grain species,a variety of storage type of storage sampling,the results shows that the modern sampling tools used,the optimization of the sampling programs do not affect the test results of the taken samples,and the sampling data collected is expected to provide support for the future development of more suitable for China’s grain storage of the sampling program.
