| 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。

| Abstract: | The experiment studied the effects of the output and ro ot activities of wheat by dressing biogas waste fertilizer.The results showed tha t dressing biogas waste fertilizer during the jointing stage and the grain filli ng stage could obviously increase the wheat yield,which was 30.7% higher than t hat of no dressing and 5.7% higher than dressing nitrogen fertilizer;The root a ctivities during the booting stage,flowering stage and ripening stage were 30.8 %,28.6% and 30.2% higher respectively than that of no dressing,and 6.3%,5.9% ,8.3% higher than dressing nitrogen fertilizer;It also improved the soil fertil ity. |
