【摘要】 新型的无损测试采用单片机和光电传感器技术,利用植株的叶绿素对不同波长的光的吸收不同和植株中叶片叶绿素含量与叶片的含氮量成正相关,通过测量作物中的叶绿素含量,来快速地测量含氮量。更多还原

【Abstract】 According to the different absorption to light with different wavelength and the positive correlation between the content of chlorophyll and that of leaf, a new type of anti-damage testing technology that make use of singlechip testing technology that make use of singlechip and photoelectric sensor technology is employed to measure nitrogenous contenl in crop through measuring chlorophyll content in crop.更多还原
