摘　　要：采用田间小区试验,研究了有机无机肥配合施用提高席草品质与产量的效果.结果表明,有机无机肥配合施用能显著提高席草分蘖和生长整齐度,对提高席草品质有明显效果,但是产量与单施化肥、单施有机肥的产量没有显著差异.从营养生长期到工艺成熟期的200多天内,有机无机肥配合施用平均苗数比对照增加116.9%,比单施化肥、单施有机肥分别高10.7%、34.3%.有机无机肥配合施用,91～100 cm席草针茎比例平均比对照增加8.2%,而单施化肥、单施有机肥处理分别比对照高5.9%和3.4%.The effect of chemical fertilizer combine with organic manure （NPKM） on quality and yield of Mat Rush were studied in the field. The results showed that the effect of NPKM on increasing numbers of tiller and promoting quality of Mat Rush were significant, but not significant on increasing yield with that of treatments of NPK and M. The number of tillers with NPKM treatments increased by 116.9% in average than that of control treatment, and increased by 10.7%, 34.3% than that of NPK and M treatments, respectively. The rate of height range in 91-100cm of Mat Rush prick haulm in NPKM treatments increased by 8.2% than that of Control treatment, but that of in NPK and M treatment increased hv iust 5.9%和3.4% than Control treatment.
