基于图像处理的胡萝卜青头须根与开裂的检测方法

为了实现基于计算机视觉的胡萝卜外观品质自动分级系统,基于图像处理的方法,参照国家标准(SB/T10450-2007),该文提出影响胡萝卜外观等级的须根、青头、开裂等关键参数的提取算法.须根检测算法通过提取骨架检测端点数来实现,青头检测算法通过R分量上二值化得到,开裂检测算法使用S分量结合区域标记的方法完成,在此基础上构建了须根数、青头比和开裂度3个量化标准,对试验随机采集的520个胡萝卜图像的青头、须根和开裂进行检测,正确率分别达到了97.5%,81.8%,92.3%,总体识别率91.3%.该文所构建的胡萝卜关键特征检测方法,对研究机器视觉的胡萝卜外观品质自动检测装置与分级生产线具有积极意义.

Study on Nitrogen Distribution in Leaf, Stem and Sheath at Different Layers in Winter Wheat Canopy and Their Influence on Grain Quality

Vertical distribution of nitrogen in wheat canopy, nitrogen remobilization and their influence on grain quality of winter wheat were studied. Two winter wheat cultivars, Jingdong8, a common cultivar, and Zhongyou9507, a high quality cultivar, were selected. Leaf nitrogen showed an obvious decreasing trend from the canopy top to the ground surface for all treatments in growth duration. There was no apparent vertical nitrogen gradient in stem and sheath of Zhongyou9507 compared with Jingdong8. Zhongyou9507 had more nitrogen remobilization from leaf, stem and sheath than Jingdong8 from middle grain filling to waxening, especially the nitrogen remobilization amount in stem and sheath, which was higher than that in Jingdong8 during growth duration. Higher vertical nitrogen gradients in Jingdong8 at anthesis had disadvantages on its grain quality. But higher vertical nitrogen gradients between middle and lower layers of Jingdong8 at grain filling stage enhanced its grain quality. Higher vertical nitrogen gradients in upper layer at anthesis and upper layer leaf and middle layer stem and sheath at grain filling stage had advantages on protein accumulation in grain of Zhongyou9507. There were positive correlations between foliar nitrogen remobilization amount and grain quality at later growth stage for the two cultivars. There was a positive correlation between quality of Jingdong8 and stem and sheath nitrogen remobilization amount from anthesis to early grain filling, and that of Zhongyou9507 emerged from anthesis to early grain filling and from middle grain filling to waxening. Contribution of leaf nitrogen to the quality of Jingdong8 was larger than nitrogen from stem and sheath. High protein content of Zhongyou9507 was attributed to the nitrogen condition in its leaf, stem and sheath. Nitrogen in stem and sheath played a more important role on the grain quality of Zhongyou9507 than on that of Jingdong8.
