中文摘要: |
土壤水分田间快速测定方法在农田水肥管理实践中有重要意义。本研究应用RR-7730M土壤湿度计,进行田间速测和室内不同含水量土壤的模拟测定,并与经典的烘箱法测定结果作了比较分析。结果表明,田间和室内模拟条件下,RR-7730M土壤湿度计速测法与烘箱法都达到极显著相关,相关系数分别为r=0.857**(n=240)和r=0.982**(n=27),说明该方法可行而且实用,值得推广。 |
英文摘要: |
Rapidly measuring the soil water content in the field is very important to the water and fertilizer management. In this paper, we using RR-7730M soil hygrometer, conducted rapid determination in the field, and simulated experiment of different water content soil in the lab, compared with the results of classical drying oven method. The results showed that in the field and indoor simulation, rapid measurement using RR-7730M soil hygrometer and drying oven method both reach significant correlation. The correlation coefficients respectively are r=0.857**(n=240) and r=0.982**(n=27). The method of rapid measurement
is feasible and practical. It is worthy to be popularized. |
