中国农业工程研究设计院遥感室受国家经委农业组的委托,与浙江省农业厅合作,在嘉兴市利用遥感技术进行水稻测产。五月二十八日至六月一日举办了培训班。水稻测产的光谱测试工作将于早稻始穗期开始。应用遥感技术对农业作物进行产量预报,是以农作物对电磁波反射和吸收等特征为基础的。农作物对电磁波的反射和吸收的大小,是随着波长的不同而变化的,所以不同农作物或不同生长期的同一农作物,这种变化规律也是不同的。这种变化规律就叫做农作物的光谱特性。
China Agricultural Engineering Research and Design Institute of remote sensing room by the State Economic Commission commissioned by the Agricultural Group, and Zhejiang Provincial Department of Agriculture, in Jiaxing City, the use of remote sensing technology for rice production. Training sessions were held from May 28 to June 1. Spectral testing of rice production begins at the beginning of early rice. The application of remote sensing technology to forecast the yield of agricultural crops is based on the characteristics of crop electromagnetic wave reflection and absorption. Crops on the electromagnetic wave reflection and absorption size, with the wavelength of the different changes, so different crops or different growing season of the same crop, the law of variation is also different. This change is called the spectral characteristics of crops.
