摘要
研究了追施沼肥对小麦产量和根系活力的影响。结果表明,在小麦拔节和灌浆期分别追施沼肥,增产效果明显,小麦产量比不追肥处理提高30·7%、比常规追施氮肥处理提高5·7%;孕穗期、开花期和成熟期的小麦根系活力,比不追肥处理分别提高30·8%、28·6%和30·2%,比追氮处理分别提高6·3%、5·9%和8·3%;并提高了土壤的供肥能力。
The experiment studied the effects of the output and root activities of wheat by dressing biogas waste fertilizer. The results showed that dressing biogas waste fertilizer during the jointing stage and the grain filling stage could obviously increase the wheat yield, which was 30. 7% higher than that of no dressing and 5.7% h ripening 5.9%, igher than dressing nitrogen fertilizer; The root activities during the booting stage, flowering stage and stage were 30.8% , 28.6% and 30.2% higher respectively than that of no dressing, and 6.3% , 8.3% higher than dressing nitrogen fertilizer; It also improved the soil fertility.
