应用数字图像技术进行马铃薯氮素营养诊断的研究
Diagnosis of N Status of Potato Using Digital Image Processing Technique
摘要
Abstract
The pictures of potato canopy were obtained with a digital camera. The relationship of potato canopy image digital index with soil inorganic nitrogen and plant N element nutrition index (petiole nitrate concentration,chlorophyll instrument reading,plant total N content,leaf total N content) under different N level were analyzed. The results showed that G/B is the moat suitable digital index for diagnosis of potato N element; the G/B quantitative standard and N recommend amount were established.关键词
