Apera spica-venti is one of the most serious annual grass weeds in Germany and may cause considerably yield losses in untreated fields. A long-term field experiment was conducted investigating the effects of crop rotation and nitrogen fertiliser use on A. spica-venti populations. A six-field cash-crop rotation with 67% winter cereals and a six-field fodder crop rotation with 50% winter cereals were studied. The rate of tillering was in the fodder crop rotation significantly higher than in the cash crop rotation. The halving of nitrogen fertilizer dose caused a significant increase in the tillering rate. Most plants of A. spica-venti emerged in winter wheat. There was an increase of emerged A. spica-venti in winter wheat from year to year.
鼠尾看麦娘是德国最严重的一年生禾本科杂草之一,在未处理的田地里可能会导致相当大的产量损失。开展了一项长期田间试验,研究作物轮作和氮肥使用对鼠尾看麦娘种群的影响。研究了一种含67%冬小麦的六田经济作物轮作和一种含50%冬小麦的六田饲料作物轮作。饲料作物轮作中的分蘖率显著高于经济作物轮作。氮肥用量减半导致分蘖率显著增加。鼠尾看麦娘的大多数植株出现在冬小麦田中。冬小麦田中鼠尾看麦娘的出苗量逐年增加。
