摘要： 摘要: 本文研究了玉米不同时期通过应用GreenSeeker 测定不同品种的玉米在不同施氮条件下归一化差值植被指数(NDVI)与叶片叶绿素含量的变化及其相关性。研究结果表明：不同时期玉米叶绿素含量与NDVI值是不同的，叶绿素含量和 NDVI值均随施氮量的增加而增大，其中最大施肥量增幅较大，叶绿素最大增幅为33%，NDVI最大增幅为7.25%，且叶绿素与NDVI呈显著正相关。不同的玉米品种增幅也不同，郑单958，吉农302要好于农大588。

Abstract: Abstract:This paper studies the different stages of corn through the application of GreenSeeker determine different varieties of corn under different nitrogen Normalized Difference Vegetation Index and the changes of leaf chlorophyll content and their relevance.The results showed that the chlorophyll content of corn at different period and the NDVI values are different,chlorophyll content and NDVI values are increased with the amount of nitrogen,the maximum fertilizer increase large,chlorophyll increase of 33%,NDVI increase of 7.25%,the chlorophyll and NDVI showed a significant positive correlation.The different varieties of corn increase different,Zhengdan 958 and Jinong 302 are better than Nongda 588.
