Estimating models of rice agronomic parameters using 3CCD digital camera
摘要
Abstract
The estimation of rice agronomic parameters is an important basis for regulating rice growth and forecast rice yield. Taking paddyfield of Rice Research Institute, Guangdong Academy of Agricultural Sciences as study case, estimation of rice leaf area index, biomass, chlorophyll contents, leaf length, leaf width, height, yield, etc were studied by 3CCD digital camera according to plant reflectance traits. The results showed that the 3CCD digital camera could not be suitable for estimating rice agronomic parameters at tillering stage, leaf area index estimation was the best at idiophase, and the estimation of biomass, chlorophyll contents, yield was better at heading stage. The 3CCD digital camera can't be used in the estimation of rice height, leaf length, leaf width etc external characteristics of paddyfield. The study provides a foundation for estimating rice yield using CCD digital cameras.关键词
