- 摘要:
- 以平欧杂种榛为研究对象，分析不同水分梯度条件下榛子果实不同生育期叶片光谱特征，采用Person相关分析筛选出榛子叶片含水量有效光谱特征参量，并以此为自变量构建榛子叶片含量一次函数、三次函数回归关系，对拟合度较高的模型进行精度分析，以确定适合榛子叶片含水量光谱反演模型，构建了榛子叶片含水量光谱反演模型，以期实现大田生产园中榛子树体水分含量的精准管理。结果表明：榛子叶片光谱反射率在可见光波段随含水量增加而降低，在近红外波段则随叶片含水量增加而增加。果实坐果期、速生生长期、脂化期和成熟期叶片含水量与水分指数WI、归一化水分指数NDVI、比值指数WI/NDVI、水分波段指数WBI、中心波长比值指数Ratio975、光化/生理反射指数PRI均达极显著相关。分别以相关性最强的有效光谱特征参量WI/NDVI、WI/NDVI、WI和WBI构建果实4个生育时期的树体含水量的三次函数估算模型具有较高精度。以上结果表明利用光谱反演模型监测榛子树体含水量是可行的。
- Abstract:
- The ‘Pingou’ hybrids was used as the research object，the spectral characteristics of hazelnut leaves under different water gradients were analyzed，and the effective spectral characteristic parameters of hazelnut leaf water content were selected by using Person-correlation analysis.Accuracy analysis of the model with high fit degree was carried out to determine the suitable water content spectral inversion model for hazelnut leaves，a spectral inversion model of hazelnut leaf water content was constructed in order to realize the accurate management of moisture content in hazelnut tree in the field orchard.The results showed that the spectral reflectance of hazelnut leaves decreased with the increase of water content in visible band and increased with the increase of water content in near-infrared band.Fruit setting period，fruit rapid growth period，fruit fat change period and fruit near-mature period，leaf water content and water index WI，normalized difference water index NDVI，the ratio index WI/NDVI，water band index WBI，central wavelength water index Ratio975，optical/physiological reflectance index PRI all achieved very significant correlation.The three function models of tree water content at different phenological periods of fruit development were constructed with the most relevant effective spectral characteristic parameters WI/NDVI，WI/NDVI，WI and WBI.The results showed that it was feasible to use spectral inversion model to monitor the water content of hazelnut trees.
