摘要

利用家禽粪便作为氮源和分解地被植物可以作为小麦作物的替代和氮管理策略。因此,本研究的目的是评估秋冬季地被植物的分离和/或间作栽培以及家禽粪便的使用对一些植物参数和小麦籽粒最终产量的影响。实验设计是随机分组,分块进行,三次重复。小区中的处理由分离的覆盖物Avena strigosa Schreb。,Raphanus sativus L.和A.strigosa+R.sativus间作和休耕作为对照。在亚地块中,小麦作物的氮管理,通过家禽粪便推荐100%的氮,通过矿物(尿素)推荐100%的N,通过家禽排泄物50%的N+50%的矿物和对照,不施用氮。氮肥和覆盖作物的管理改变了小麦作物的产量构成。家禽粪便的使用增加了最终谷物产量,当与尿素或总氮相关时,作为部分替代品,这是一种替代品。分离作物R.sativus和a.strigosa+R.sativus间作显著影响农艺性能和最终谷物产量。

Poultry litter and cover crops influence the agronomic performance and grain yield of wheat
The use of poultry litter as a source of nitrogen (N) and the decomposition of ground cover plants can be an alternative and N management strategy in the wheat crop, in succession. Therefore, the objective of this study was to evaluate the effect of isolated and/or intercropped cultivation of ground cover plants in autumn/winter and the use of poultry litter on some plant parameters and on the final yield of wheat grains. The experimental design was randomized blocks, in split plots, with three replications. The treatments in the plots were composed of isolated coverings Avena strigosa Schreb., Raphanus sativus L. and intercropping of A. strigosa + R. sativus and fallow as a control. In the subplots, the N managements in the wheat crop with 100% of the N recommendation via poultry litter, 100% of the N via mineral (urea), 50% via poultry litter + 50% mineral and the control, without N application. The management of nitrogen fertilization and the cover crops altered the yield components of the wheat crop. The use of poultry litter increased the final grain yield, being an alternative as a partial replacement, when associated with urea, or total N. Isolated crops R. sativus and A. strigosa + R. sativus intercropping significantly influenced agronomic performance and final grain yield.
