Abstract:

‘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.
