摘要
本文综合前人成果,利用开发的植物病害诊断仪对林木枝干典型毁灭性传染性病害腐烂病等和常见的生理性病害低温灾害的试验,证明仪器对多种林木的根、茎、果实上的病害位置、大小、发病时期能够测试,对处于未显症的绝大多数非传染性病害和隐蔽部位已显症的病斑有100%的准确率,甚至还能检测部分潜育的病斑。因此对植物病害的早期诊断有实用意义。不但使业者获得节约开支、提高产量和质量等实惠,而且有大幅降低农药用量、减少次数、减少大气、水、产品药残等一系列的生态环境效益。
This paper first gives a review of early work. Introduce a new method using PDDI(Plant disease diagnosis instrument), and demonstrated that PDDI is very effective in diagnosis of common plant disease with 100% accuracy. Also because it is economic, it will be affordable and practical. The conlusion is PDDI is a effect IPM method giving more protection of environment and food.
