RR-7730M土壤湿度计田间快速测定土壤含水量方法研究
A rapid measurement method of soil water content in the field using RR- 7730M soil hygrometer
摘要
Abstract
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 popularised.关键词
