摘要: Multiple means of overcoming interspecific competition between transplanted cabbage and interseeded cover crops were studied in field trials conducted from 1995 to 2001. Cover crop species time seeding (1995 1996), use supplemental nitrogen (1997 1998), herbicide regulation (1999 2001) evaluated with the objective integrating soil-improving into production while facilitating weed suppression minimal herbicides. Cabbage was cultivated at 10, 10 + 20, or 20 30 d after transplanting (DAT) without (hairy vetch, lana oats) sown last cultivation. Early interseeding (10 DAT) all significantly reduced yields. Both vetches could be DAT a yield penalty. However, not consistently greater than cultivation crops. Spring oats unacceptably competitive, even when some years. With additional nitrogen, cabbag...
