Abstract

The infestation of Bromus species in small grains, especially in winter cereals has increased over recent years. In some areas winter wheat growers consider Bromus spp. as their worst grass weed. Besides yield reduction, Bromus spp. cause lodging and complication of harvest. In Germany the two most dominant species are Bromus sterilis (L.) and Bromus secalinus (L.). In order to develop control strategies the population dynamics of the weeds were investigated. Based on the results a deterministic mathematical model using differential and algebraic equations was used to estimate changes in the population of the two Bromus species.

摘要

近年来，雀麦属植物在小粒谷物，尤其是冬小麦中的侵染情况有所增加。在一些地区，冬小麦种植者将雀麦属植物视为最严重的禾本科杂草。除了导致产量下降外，雀麦属植物还会引起倒伏并使收获变得复杂。在德国，两种最主要的雀麦属植物是不育雀麦（Bromus sterilis (L.)）和黑麦状雀麦（Bromus secalinus (L.)）。为了制定防治策略，对这些杂草的种群动态进行了调查。基于这些结果，使用了一个由微分方程和代数方程组成的确定性数学模型来估计这两种雀麦属植物种群的变化。
