中文摘要:对土耳其斯坦叶螨Tetranychus turkestani (Vgarov et Nikolski)为害程度不同(0,1,2,3,4级)的棉叶进行光谱测试,并按螨害级数测定光谱测试后棉叶的叶绿素和类胡萝卜素含量。结果表明:随着螨害的逐渐加重,棉叶的叶绿素含量逐渐下降,类胡萝卜素含量逐渐上升
英文摘要:The spectrum of cotton leaves infested in different levels by Tetranychus turkestani(Ugarov et Nikolski) were measured using ASD Leaf Clip. Meanwhile, the contents of chlorophyll and carotenoid in these cotton leaves were measured. The res
