| 以淮山黑美人品种为试验材料，通过对不同播种期、种植密度和种薯段位对其生长和产量的影响进行研究，结果表明：随着播种期的推迟，出苗期有所提前，生育期和全生育期则相应缩短。播种期的早晚对产量有明显差异，其中以5/1种植的产量最高，平均小区产量57.02 kg，折合667 m2产量为2112.02 kg，商品薯率为88.74%。综合产量及商品薯率进行比较，最佳种植密度每667 m2为1900株，平均小区产量56.92 kg，折合667m2产量为2105.18kg，商品薯率达到87.93%。种薯选择以上、中段薯较佳，能提早出苗，提高出苗率，促进苗齐苗壮。研究结果对海南解决5~8月无鲜薯上市的野淮山淡季冶问题提供了重要技术保障。 |

| Using Chinese yam Heimeiren as the experiment material, the effects of different sowing date, planting density and position of tuber on the growth and yield were studied in Hainan. The results showed that the emergence date was early and growth period was shorted with the delay of sowing date. Different sowing dates had a significant effect on the yield. The yield was the highest when the sowing date was January 5 th, with the average yield per plot 57.02 kg(2112.02 kg per 667 m2) and marketable percentage 88.74%. The optimum planting density was 1 900 plants per 667 m2 with the average yield per plot 56.92 kg (2 105.18 kg per 667 m2) and marketable percentage 87.93%. Upper and middle position of tuber should be selected as seeds, which could make seeds germinate ahead, improve rate of seedling and promote plants strong and even. The result could provide an important technical support to settle Chinese yam off-season from May to August in Hainan province. |
