摘要
在番茄生长过程中,营养元素(如:氮、磷、钾)供应的均衡对其生长有着重要的影响。文中介绍了传统营养元素诊断方法和近红外光谱技术在农业检测中的应用特点,并对新近发展起来的Monte Carlo仿真方法和在线动态漫反射光谱检测法进行了简要分析,通过应用这些方法,可以建立番茄的营养元素供应模型,并分析营养元素与近红外光谱之间的内在关系。
The nutrient element(e.g.nitrogen,phosphorus or potassium)balances have a significant impact on tomato growth. The application features of both conventional methods and near infrared spectrum technique in plant nutrition were introduced. Also the newly developed Monte Carlo simulation method and on-plant measuring technique using dynamic diffuse reflectance spectroscopy were analyzed.Using those methods,the tomato nutrient elements supply model could be established,and the relationship between nutrient elements and NIR spectrum could be analyzed.
