摘要
采用多光谱辐射测量法对相同草坪草品种在相似管理下的冠层属性进行了定量分析。缺乏对草坪草冠层应用后24小时的多光谱辐射特性的关注。我们的目标是评估石油衍生喷雾剂(PDSO)和合成Cu II酞菁着色剂(CPC)组合产品在施用后10天内对匍匐曲草(Agrostis stolonifera L.)反射率的影响。维持原状的球道每半月单独或联合27 L PDSO+CPC ha-1处理9.76 kg ha-1可溶性氮。PDSO+CPC处理增加了平均茎部生长量(kg ha-1)和可见波段反射率计算的深绿色指数(DGCI)。然而,PDSO+CPC处理地的远红外和近红外反射率降低了,人为地降低了平均归一化差异营养指数。在评估经PDSO和Cu II酞菁组合产品处理的球道时,应谨慎解释依赖于710 - 810 nm冠层反射率的营养指数。
Reduced creeping bentgrass fairway reflectance following synthetic colorant application
Repeated measures using multispectral radiometry resolutely quantify canopy attributes of identical turfgrass cultivars under similar management. Concern regarding multispectral radiometric characterization of turfgrass canopies <24 h following synthetic phthalocyanine colorant application has been affirmed and is accordingly now avoided; yet explicit guidance on subsequent employ, at time(s) > 24-h postapplication, is lacking. Our objective assessed how petroleum-derived spray oil (PDSO) and synthetic Cu II phthalocyanine colorant (CPC) combination product influences creeping bentgrass (Agrostis stolonifera L.) reflectance up to 10 d following application. A maintained fairway received semimonthly 9.76 kg ha–1 soluble N treatments alone or in combination with 27 L PDSO+CPC ha–1. Treatment by PDSO+CPC increased mean shoot growth (kg ha–1) and dark green color index (DGCI) calculated by visible waveband reflectance. Yet reduced far red and near infrared reflectance from PDSO+CPC treated plots artificially deflated mean normalized differential vegetative indices. Cautious interpretation of vegetative indices relying on 710-to-810-nm canopy reflectance is encouraged when evaluating fairways treated by PDSO and Cu II phthalocyanine combination product(s).
