一、种子处理概述种子常常受到大量植物寄生虫和动物害虫的侵扰。为减少这种危害,建议在无病区域生产种子以及播种抗病虫害的作物品种。许多植物寄生虫(真菌和病原菌)损害发芽和植物的后继生长发育;动物害虫(昆虫、鸟类)则侵害秧苗,种子处理可以有效地抵抗这些病虫害。种子处理是用化学物质对种子进行的处理,即把杀真菌剂和杀虫剂施加于种子表面并粘附其上的过程。为了使化学药剂牢固地粘附在种子上,种子处理前必须清选(例如除去灰尘)。由于化学药剂含有毒物质,处理的种子必须有标记,因此应在药剂中添加警戒色,通常是红色。种子处理主要用于抵抗在种子表面发现的病害(如小麦腥黑穗病——Tilletia caries),但也有
I. Overview of Seed Treatment Seeds are often invaded by a large number of plant parasites and animal pests. To reduce this hazard, it is advisable to produce seeds in disease-free areas and to plant crop varieties resistant to pests and diseases. Many plant parasites (fungi and pathogens) impair germination and subsequent plant growth and development; animal pests (insects, birds) attack seedlings and seed treatments are effective against these pests. Seed treatment is the treatment of seeds with chemicals, the process of applying fungicides and insecticides to the seed surface and adhering to it. In order for the chemical to adhere firmly to the seed, the seed must be cleared (eg, dust removed) prior to treatment. Due to the chemicals containing toxic substances, the treated seeds must be marked, so add a cautionary color to the agent, usually red. Seed treatment is mainly used to resist diseases found on the seed surface (such as Tilletia caries), but there are also
