陇南山区马铃薯病虫害无公害综合防治技术 总被引:1,自引:0,他引:1
马铃薯是陇南武都、礼县、西和、宕昌四县主栽作物之一。主栽区年降水低于 5 5 0mm ,属旱作农业 ,绝大部分为春季一季作。全区现马铃薯种植面积 4 7万hm2 ,年产鲜薯 5 0万t。据不完全调查 ,马铃薯病虫害近 70种 ,因病虫害而减产在12 %~ 30 %,严重年份减产在 5 0 %以上 ,是造成生产中产量不稳定、产品商品率低的重要因素。常见病虫害有 14种 ,与发达地区相比我区防治水平低 ,存在较大差距 ,在多年的田间管理实践中 ,以预防为主 ,综合防治为出发点 ,总结了一套生产无公害绿色产品的病虫害综合防治技术。1 种子防治1 1 选种选种包括两层… 相似文献

浅谈茶叶病虫害综合防治 总被引:2,自引:0,他引:2
茶叶病虫害自人类发现茶叶有解毒饮用功效并栽培以来.就一直困扰着人们。古代人们多采用人工、物理措施防治病虫。19世纪有机合成农药诞生,才为人类防治植物病虫害发挥了巨大的作用。但随着时间的推移,人们发现单一的有机合成农药防治技术,不仅使病虫产生抗药性,杀伤天敌,而且污染环境,对人类健康造成巨大威胁。上个世纪60年代以后,人类反思有机合成农药的优劣,开始引入生物防治与微生物防治。同时开拓传统的农业、物理防治技术,形成茶叶综合防治的概念。 相似文献

SUMMARY Cropping systems have been central to managing associated pests for centuries. This treatment focuses on the history, concepts, and the integration of available Integrated Pest Management (IPM) tools/strategies into cropping systems. Pest assessments/diagnoses, IPM-decision-making aids, and examples of pest management in selected crops/cropping systems (wheat, soybean, corn, cotton, potato, and strawberry) as well as emerging opportunities and challenges are discussed. The evolving philosophy of IPM and the recently renewed emphasis on ecologically based pest management address the fact that significant levels of predation and/or parasitism are desirable insofar as they promote diversity and sustainability of agroecosystems. Thus, cropping systems are beginning to focus on soil and crop health as well as specific IPM and production goals. Although extensive efforts have been directed toward modeling the many interactions between crops, associated pests and the environment, the general implementation of a systems approach to integrated crop and pest management remains to be accomplished. 相似文献

Józefa S. Kapsa 《Potato Research》2008,51(3-4):385-401
Since the 1970s climate in Europe warmed rapidly. Over the next years climate is expected to become gradually milder and more humid in northern Europe and hotter and drier in southern Europe. These changes are forecasted to be responsible for major changes in the distribution of plant and animal species, pathogen/pest prevalence and their biodiversity. On the other hand, some changes in variability and epidemiology of pathogens are affected by biological factors. In the first part of this paper an overview is given of pathogens and pests that are potentially affected by climate change and are or will become a significant threat in potato production. The second part of the paper deals with integrated crop protection of potato against various pathogens and pests, considered the best solution for these disease and pest problems. Management of persistent and recurrent diseases and pests of potato requires the integration of many control measures to achieve an efficient crop protection. The protection of potato has to start very early before planting. 相似文献
