| 中文摘要: |
| 以木薯品种新选048 为材料，设药肥300、600、900 kg/hm2 和空白对照4 个处理，通过测定土
壤碱解氮、速效钾、速效磷含量，木薯株高、茎粗、叶片及块根可溶性糖含量等生理指标，并测定木薯主要
经济性状及产量，探讨药肥对木薯产量及其相关性状的影响。结果表明，施用药肥能明显改善土壤养分状
况，提高碱解氮、速效钾及速效磷含量，促进木薯生长和对养分的吸收，改善块根性状，提高块根可溶性糖
含量。与对照相比，300、600、900 kg/hm2 药肥处理的块根产量分别提高21.20%、23.91% 和14.31%，表明适
量的药肥利于木薯增产，药肥用量过多反而使产量下降，综合成本、块根性状及产量等因素，300 kg/hm2 药
肥处理的效果最好。 |
| 英文摘要: |
| The effects of drug fertiliter on yield and related traits of cassava were studied by detection the
contents of soil alkali hydrolyzable nitrogen，available potassium and available phosphorus，plant height，stem
diameter，content of soluble sugar in leaf and root，main economic characters and yield of cassava. Four treatments
were set with XinXuan048 as material，respectively CK（0 kg/hm2），300 kg/hm2，600 kg/hm2 and 900 kg/hm2. The
results showed that the nutrient status of soil and contents of soil alkali hydrolyzable nitrogen，available potassium and
available phosphorus were improved by using drug fertilizer，thus good for the growth of cassava and the improvement
of root traits，and could increase the content of soluble sugar of root.Compared with control，the yeild of 300 kg/hm2，
600 kg/hm2 and 900 kg/hm2 treatments increased by 21.20%，23.91% and 14.31%，which showed that suitable drug
fertilizer was condutive to the yield of cassava，but the yield decreased by too much drug fertilizer. In consideration of
cost，root traits and yield，the effect of 300 kg/hm2 treatment was the best others. |
