一种基于冠层多光谱的烤烟地上鲜生物量测定方法
摘要：
一种基于冠层多光谱的烤烟地上鲜生物量测定方法，其特征在于：采用多光谱辐射计对团棵期到现蕾前期的烤烟冠层光谱进行测定，构建植被指数，利用统计学方法建立利用冠层光谱参数反演烤烟地上鲜生物量的模型，测定待测样本的冠层光谱参数，输入模型，进而实现对烤烟地上鲜生物量的测定。本方法与技术背景相比有以下优势：1.原位测定，不需要取样，对烟株无损伤；2.与高光谱辐射计相比有较大的成本优势，更适用于农业生产；3.只需获得550nm和1050nm两通道的数据就可以完成测定，数据处理方法和过程简便。
摘要（英）：

The invention relates to a method for determining aboveground fresh biomass of flue-cured tobacco based on canopy multi-spectra, which is characterized by comprising the following steps of: determining the canopy spectra of the flue-cured tobacco from a resettling stage to a budding early stage by a multispectral radiometer; establishing vegetation indices; establishing a model for inverting the aboveground fresh biomass of the flue-cured tobacco by the canopy spectra parameters by a statistical method; determining the canopy spectra parameters of a sample to be determined; and inputting the canopy spectra parameters into the model, thereby realizing the determination of the aboveground fresh biomass of the flue-cured tobacco. Compared with the prior art, the method has the advantages of in-situ measurement, no need of sampling and no injury to tobacco plants; compared with a hyperspectral radiometer, the method has a larger cost advantage and is more suitable for agricultural production; the determination can be finished only by acquiring data of a 550nm channel and a 730nm channel; and the data processing method and process are simple and convenient.
