作物生态学crop ecology
作物育种plant breeding Raising a certain type of plant by crossing one variety with another to produce a new variety where the desired characteristics are strongest (通过与别的品种嫁接,得到期望特征的新的品种。)
作物保护crop protection The problem of crop protection has changed dramatically since 1945. There is now a whole arsenal of chemicals with which to combat agricultural pests and diseases, but this development has itself many drawbacks. Such sophisticated techniques are available only to a minority of farmers; in most parts of the world the standard of crop protection remains abysmally low. In addition, modern crop protection methods have been criticized for relying too heavily on chemical control. Biological controls, both natural and contrived, have been neglected. In some cases involving misuse of agricultural chemicals, crops must be protected from the very measures intended for their protection. Meanwhile previously localized pests and diseases continue to spread worldwide (自从1945年以来,农作物保护问题发生了巨大的变化。现在我们有许多化学试剂用以对付农作物害虫和疾病,但这种发展本身也存在着许多不足。例如,成熟的技术仅能被少数农民所利用;在世界范围内,农作物保护的标准仍然很低。此外,现代的农作物保护措施也因为过多依赖化学手段控制而受到指责。生物手段控制,无论是自然的还是人工的都被人们所忽略。在误用农用化学试剂的情况下,需要采用适当的方法来包括农作物。与此同时,先前存在的重害病仍在世界范围内传播。)
作物生产crop production The act or process of yielding produce from farmland, for livestock or human consumption (为家畜或人类需求而从事生产农产品的行为或过程。)
作物虫害infestation of crops Invasion of crop by parasites. Among vertebrate animals, many crop pests are mammals, especially in the order of rodents and birds. Among invertebrates, certain species of gastropods and a large number of roundworms from the class of nematodes harm crops. The most varied and numerous species of crop pests are arthropods-insects, arachnids and some species of millipedes and crustaceans. Diseases vary from viral, bacterial, and nutritional to fungal, environmental and non-specific. The FAO has estimated that annual worldwide losses done by plant pests and diseases amount to approximately 20-25% of the potential worldwide yield of food crops (农作物遭受寄生虫的侵害。在脊椎动物中,许多的作物害虫为哺乳动物,尤其是啮齿目动物和鸟类。在无脊椎动物中,某些种类的腹足动物和数量颇大属线虫纲的迴虫也会对作物造成危害。种类最多和数目最大的作物害虫为节肢昆虫、蛛形纲动物和某些种类的节肢动物和甲壳纲动物。病害随著病毒、细菌、真菌、覃菌类营养和环境而异。FAO (联合国粮农组织) 估计每年全世界植物病虫害的损失约占全世界食用作物产量的20~25%。)
作物防治crop treatment Use of chemicals in order to avoid damage of crops by insects or weeds (用化学物质防止农作物被害虫和杂草所伤害。)
农作废弃物crop waste Any unusable portion of plant matter left in a field after harvest (收割后弃于田地间、没有任何使用价值的农作物部分。)
协同作用的有毒物质synergistic effect of toxic substances 1. A state in which the combined effect of two or more substances is greater than the sum of the separate effects. 2. An effect whereby two toxic substance together have more of an impact than anticipated (1. 在一个国家里,两个或两个以上的物质结合效果总和比单独作用的效果强。 2. 作用,使两种有毒物质具有一个共同的影响比预期的更强。)
块根农作物root crop Plants which store edible material in a root, corm or tuber; root crops used as food vegetables or fodder include carrots, parsnips, swedes and turnips; starchy root crops include potatoes, cassavas and yams (根、球茎或块茎且能食用的植物;块根农作物作为食物、蔬菜或草料包括胡萝卜、欧洲防风草、甘蓝和萝卜;淀粉块根作物包括马铃薯、木薯和红薯。)
工业作物有机体、生物, 用于工业上的栽种作物,例如棉花、亚麻、大麻(纤维)、花生等。industrial plant Plants employed in industry, e.g. cotton, flax, hemp, peanuts, etc.; organism
工业原料作物industrial crop Any crop that provides materials for industrial processes and products such as soybeans, cotton (lint and seed), flax, and tobacco (任何一种可供工业生产和加工原料的作物,如大豆、棉花(棉絮及种子)、亚麻和烟草等。)

抗旱作物drought-tolerant crop
有害作业物质hazardous working material A poison, corrosive agent, flammable substance, explosive, radioactive chemical, or any other material which can endanger human health or well-being if handled improperly (一种有毒的、有腐蚀性的介质、易燃物、易爆物、放射性化学品或其他任何若处理不当则可危及人类健康或福祉的物质。)
有害废物作业和应急对策Hazardous Waste Operations and Emergency Response
毒性物质的拮抗作用antagonistic effect of toxic substances
经济工业原料作物industrial crop
经济作物cash crop Crops that are grown for sale in the town markets or for export. They include coffee, cocoa, sugar, vegetables, peanuts and non-foods, like tobacco and cotton. Huge areas of countries in the developing world have been turned over to cash crops. Those countries with no mineral or oil resources depend on cash crops for foreign money, so that they can import materials do develop roads, for construction, or to buy Western consumer goods and, indeed, food. However, critics argue that cash crops are planted on land that would otherwise be used to grow food for the local community and say this is a cause of world famine. Cash crops, such as peanuts, can ruin the land if it is not left fallow after six years of harvests. Moreover, if the best agricultural land is used for cash crops, local farmers are forced to use marginal land to grow food for local consumption, and this has a further dramatic effect on the environment (供市场出售或出口而种植的农作物。包括咖啡、可可、糖、蔬菜、花生和非食用作物,如烟草、棉花。发展中世界的很多国家已经转向了种植经济作物。那些没有矿产、石油资源的国家依靠经济作物来获取外币,以使它们能够在建筑方面通过进口材料来建设道路,或者购买西方消费产品以及食物。然而,有评论说,经济作物种植在了那些可以供当地居民种植食物的土地上,这是导致世界饥荒的一个原因。经济作物,例如花生如果在收获之后不休耕六年就会毁坏土地。再者,如果最好的农耕土地用来种植经济作物,当地农民不得不用边际土地来种植食物以供当地消费,这将进一步影响环境。)
耐旱作物drought-tolerant crop
耐旱作物drought-resistant crop
饲料作物forage crop Cultivation of crops for consumption by livestock (供牲畜消费而栽培的农作物。)
