摘要: 以生长势不同的酿酒葡萄品种赤霞珠和梅鹿辄为试材, 采用基于地物光谱特性的遥感技术获得地块内不同生长势(包括新梢长度、新梢日生长速度、单株叶面积、N-Tester指数) 小区的归一化植被指数(NDVI) 间存在显著差异, 并且NDVI与葡萄新梢长度、新梢日生长速度、植株叶面积以及N-Tester指数间具有显著或极显著的相关性。因此, 采用NDVI评价地块内葡萄长势差异性具有应用前景。

Abstract: Two grapewine making cultivars, Cabernet Sauvignon and Merlot (Vitis vinifera) , were used in this study to estimate vine vegetative vigour by the remote sensing technique. The results show that the normalized difference vegetation index (NDVI) of grapevines based on on-ground object spectral data distinguished well the intraplot vine vegetative vigour, including shoot length, shoot daily growth rate, leaves areas pervine and N-Tester index. Significant correlations were found between NDVI and shoot length, shoot daily growth rate, leaves areas pervine, or N-Tester index. The results indicate that NDVI could be used for evaluating the grapevine intra-plot vegetative vigour and the GIS distributed NDVI map might be used to distinguish
different grapevine vigour zones.
