以‘嘉祥细毛长山药’栽子为材料，采用随机区组试验方法，研究不同肥料配比、种植密度及地膜覆盖对山药产量的影响。试验结果表明，复混肥料、微量元素肥料以及生物有机肥等几种新型的肥料配合使用能够显著提高山药产量；‘嘉祥细毛长山药’最适宜的种植密度是48000株/hm2；地膜覆盖能显著提高‘嘉祥细毛长山药’产量，但应注意覆膜后的田间管理。研究表明，‘嘉祥细毛长山药’尚存在很大的增产潜力，合适的栽培技术能显著提高山药产量。

‘Jiaxiangximao Chinese Yam’ was used to study the effects on yield of different fertilizer proportion, different plant density and plastic film mulch, the experiment was carried out by randomized blocks design. The results showed that the yield of yam could increase significantly when mixed application of several new type of fertilizers included compound fertilizer, trace element fertilizer and bio-organic fertilizer. The results also showed that the most suitable planting density for ‘Jiaxiangximao Chinese Yam’ was 48000 plants/hm2, and showed that plastic film mulching could significantly improve the production of yam, but should pay attention to the field management after film mulch. This research showed that there was a great yield potential on ‘Jiaxiangximao Chinese Yam’, and suitable cultivation technique can significantly improve the production of yam.
