Applying and Combining Disturbance and Competition for an agro-ecological management of creeping perennial weeds

AC/DC-杂草的目标是开发、检查和实施更多和更好的农业生态管理，以期在农田耕作中对多年生爬行植物进行管理。总体目标是减少有机耕作和常规耕作中的耕作--后者也是为了取代草甘膦的应用。用较少的除草剂来控制多年生杂草的田地将允许一年生杂草植被中有更多的生物多样性。多年生杂草的农业生态管理的新方法需要开发、结合和评估基于文化、物理和生物的化学防治。多年生爬行植物受到干扰或竞争的抑制，因此，农业生态管理必须以适当和合理的方式激活这些过程。我们建议在更好地了解这些过程的基础上，研究农业生态管理的新方法。来自5个欧洲国家的7个伙伴希望进行合作，这些国家代表着中欧和北欧相当大范围的气候和耕地生产条件。交流/直流-杂草将被组织成7个工作包。每个工作包都使用了关于知识状况、预期结果和设想的外出活动的最有希望的方法。在田间试验中，将研究在地下施加干扰而不翻土的新方法，以及使用生物兼容除草剂的落叶策略。联合田间试验的结果将检验这些新方法的有效性和实用性。竞争加剧的影响经常被调查。关于爬行多年生植物的现有结果将在荟萃分析中系统化。提取的知识将提供给基于特征的联合数据库。中欧和北欧三个最重要的物种在生物学和生态学上存在差异。通过特定的小规模实验，汇集了披碱草、蓟属和长穗披碱草的具体数据，找出了知识差距，并缩小了差距。我们采用新的方法，通过安装在无人机上的可用传感器，在空间上明确地监测这些多年生植物。将开发可靠的算法来区分和监测多年生植物。将设计定性模型，分析种植方式、土壤、天气和田间环境对常年虫害的影响。在一种新的交互式图形网络工具的帮助下，将开发针对应用干扰和竞争的不同场景的空间可视化。协调从根本上保证了合作伙伴之间的数据流动、交换和沟通。提供了一个数据框架，用于将实验结果、描述性和分析性特征和基于物种的方法提供给技术应用。结果的传播得到了协调和支持。由于外展成果的目标将是改变种植技术，因此将提供对环境和经济的影响评估，以完成传播。所有WPS和合作伙伴的成果和产品将被传播。

The objective of AC/DC-weeds is to develop, examine and implement more and better agro-ecological management for creeping perennials in arable farming. Overall aim is to reduce plough-tillage in organic and conventional farming - in the latter also to replace glyphosate applications. Fields with less herbicide use to control perennial weeds would allow more biodiversity in the annual weed vegetation. Novel approaches for agro-ecological management of perennial weeds demand to exploit, combine and evaluate cultural, physical and bio-based chemical control. Creeping perennials are suppressed by disturbance or through competition hence, an agro-ecological management must activate these processes in a suitable and rational way. We propose to investigate new ways of agro-ecological management based on a better understanding of these processes. Seven partners from 5 European countries, representing a considerable area of Central and Northern European climatic and arable production conditions want to collaborate. AC/DC-weeds will be organized in 7 work packages. Each work package uses the most promising methodology regarding the state of knowledge, expected results and the envisaged outreach.New ways of applying disturbance subterranean without turning the soil will be examined in field experiments together with defoliation strategies with biocompatible herbicides. Results from joint field experiments will test efficacy and practicability of these new ways. The effects of enhanced competition are frequently investigated. Existing results on creeping perennials will be systematized in a meta-analysis. The extracted knowledge will feed a trait-based joint database. Three most important species in Central and Northern Europe differ in biology and ecology. Specific data for Elymus repens, Cirsium arvense and Sonchus arvense are pooled, knowledge gaps identified and close through specific small scaled experiments. We follow new approaches to spatially explicit monitor these perennials with available sensors installed in drones. Reliable algorithms will be developed to distinguish and monitor perennials. Qualitative models to analyse the impact of cropping practices, soil, weather and field environment on perennial infestations will be designed. With the help of a novel interactive graphical web tool spatial visualization for different scenarios of applying disturbance and competition will be developed. Coordination fundamentally ensures data flow, exchange and communication among partners. A data framework is provided to feed experimental results, descriptive and analytical trait and species based approaches into technological applications. Dissemination of the results is coordinated and supported. As outreaching results will aim on altering cropping technologies, evaluation of effects on the environment and on economic will be provided to accomplish dissemination. Results and products of all WPs and partners will be disseminated.
