土壤采样器采样性能试验研究

Research on Soil Sampling Performance of Soil Sampler

农田土壤样品的快速获取及分析对科学施肥具有重要意义。土壤采样器是农田土壤采样的重要设备,获取和松放土壤的能力是评价其采样性能的重要指标。本文通过试验,从土壤样品长度和土壤松放后残余土壤质量两个方面分析自行设计的5种土壤采样器的采样能力,指出了1号土壤采样器设计综合采样性能较好。

It is important to fertilize in farm field that the information of soil nutrient are fast gotten by soil tool. Soil tests provide a scientific basis for evaluating available plant nutrients in farmland and analyses of soil samples can help farmers fine-tune nutrient applications from fertilizers and save money and protect the environment. Soil tool is an important instrument in the process of soil sampling, its performance quality decides the soil sample′s quality. This research is aim at carrying experiments on five kinds of soil tool (designed by College of Engineering, South China Agricultural University), and gather the information of the different soil tool. The information is mainly about sampling performance of the soil tool, so we can make further improvement to the tool. According to the test, No·1, a soil tool which has good sampling performance is given out for soil sampling in farmland.
