Determining Toxicity of Several Chemical Pesticides Against Olethreutes leucaspis in the Laboratory LI Rong-Xing, ZHONG Yi-Hai, CHEN Ze-Tan (Institute of Environment and Plant Protection, Chinese Academy of Tropical Agriculture Science, Hainan Province, Danzhou 571737, China) Abstract: Using a stomach poisoning method, the toxicity of five chemical pesticides to Olethreutes leucaspis Meyrick larvae was determined under laboratory conditions.

几种化学药剂对三角新小卷蛾的室内毒力测定李荣幸，钟义海，陈泽坦(中国热带农业科学院环境与植物保护研究所，海南儋州571737)摘要室内条件下采用胃毒法测定了5种化学药剂对三角新小卷蛾幼虫的毒力。

The world's twentieth-century shift to high chemical-input farming was facilitated by high labor costs and low input costs, including land and chemicals, as well as a shift away from a stewardship approach to a productionist outlook, and it has been enabled by the economic treatment of environmental degradation and pesticide contaminations as externalities, rather than as costs of production.

二十世纪，世界上的农业转向高化学产品投入，它依靠高人力成本和低投入费用辅助，利用土地和化学产品，以及从管理工作方法到生产者前景转变，同时，它由环境退化和杀虫剂污染的经济处理作为外在形式，而不是作为生产成本。

Combinating the siol column and potted plant experiment synthesize analysis that the soil alkalinity below 30% can be all improved by hydraulic and agricultural measure without the chemical amendment. When the alkalinity is over 30%, however, the alkaline soil must be made use of the chemical measure gathering water conservancy to attain improvement .

结合土柱试和盆栽试验的结果综合分析，在土壤碱化度低于30%的轻、中度碱化土壤通过水利与农业措施相结合的办法而不用化学改良剂就可以改良好；而碱化度大于30%的土壤，必须在水利措施的配合下，利用化学改良剂才能达到改良的目的。

Organic agriculture is aimed to reduce external inputs by refraining from the use of chemical fertilizers and chemical pesticides.

有机农业的目标是避免使用化学肥和化学农药，减少外界元素。

In this paper, necessity of water saving agriculture in Loess plateau wasanalysized, and main types of regulating soil water techniques were sumed up as below, the aimof regulating soil water could be got by use of building up fertilizer, crop rotation, intermitentfallowing soil, drought resistant breeding, water savins run-off agriculture and chemical method.

通过对黄土高原节水农业必要性的分析，并总结出调水技术的主要类型为：培肥地力以肥调水；轮作倒茬调水；间隙休闲调水；抗旱育种调水；节水灌溉调水；径流农业调水和化学技术调水。

Every year, waters on earth receive large quantities of wastewater from industry, agriculture, fish and poultry raising, and municipal sewage treatment plants. Consequently, the aquatic environment on the earth is under a serious challenge from a very large quantity of pollutants such as antibiotics, insecticides, herbicides, hydrocarbons, etc., contained in the domestic wastewater, industrial and agricultural waste water and illegal effluents. In particular, with the development of intensive aquiculture and poultry, the effluent pollution has recently become more and more serious with more attentions. Furthermore more and more chemical pollutants discharged into aquatic environment have been detected with the advancement of analytical techniques. These chemicals can cause toxic effects on water habitats after discharged into aquatic environment.

每年有大量来自工业、农业、养殖业和城市污水处理厂的废水被排入到水环境中，因此，地球上的水环境面临大量来自生活废水、工农业废水、非法排放的废水及其它废水的污染物质(如抗生素、杀虫剂、除草剂、烃等)的严重挑战，特别是近年来随着集约化养殖的发展，废水污染问题日益突出，并且随着分析手段的进步，能够检测到被排入水环境中的化学污染物质也越来越多，这些化学污染物对水环境中的生物产生有害影响。

It is obvious that the potential environmental impact of crop insurance depends on farmers' decisions with regard to agrochemical application under current social, economic, and environment conditions.

显然，农业保险制度的环境效果取决于既定的社会、经济与环境条件以及特定的农业保险条款下农户对农用化学要素的施用决策。
