【摘要】 杂草在田间非均匀分布,为了减少除草剂的用量和减轻污染,应采取化学除草剂精确施药技术,其关键在于实时识别杂草。目标探测与识别是精准施药技术体系的主要研究内容之一,是精准施药技术的关键环节。杂草光谱识别因其快速性、实效性、成本低、易形成商业化等特点,在各种杂草识别技术中具有明显的优势。本文主要从杂草光谱识别的研究意义、研究现状、理论依据、存在的问题、及发展方向等方面进行了论述。更多还原

【Abstract】 Target detection and recognition is one of the main research content and also an key point in chemical precision applica- tion technology system.Weeds are uneven in the field.In order to reduce the dosage of herbicides and prevent or minimize enviro nmental pollution,chemical herbicides should be sprayed accurately,namely,some precision application should be adopted. Therefore,firstly weed should be recognized in real-time.Weed spectral discrimination technology has obvious potential and ad- vantages in weed detection because of its rapidity,actual effects,low cost,and easiness to be commercialized.This article main- ly diseusses on aspeets of research meaning,research current situation,theory foundation,open question,and developmental di- rection in weed spectral discrimination.更多还原
