| 摘 要： | 目的]探索海南冬种马铃薯(Solanum tuberosum)的适应性及其栽培技术措施。方法]以马铃薯品种费乌瑞它为试验材料,分别就播种期、种植密度和栽培方式进行试验,研究不同播种期、种植密度和栽培方式对海南冬种马铃薯生长及产量的影响。结果]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影响较大,其中以11月14日播种的产量最高,小区平均产量为35.16 kg,折合产量为19 330.20 kg/hm2,商品薯率为92.75%。种植密度以7.5万株/hm2最好,小区平均产量20.53 kg,折合产量23 108.10 kg/hm2,商品薯率为97.08%。栽培方式以黑色地膜覆盖栽培最佳,能提早出苗,提高出苗率,促进苗齐苗壮,小区平均产量20.31 kg,折合产量为22 333.50 kg/hm2,商品薯率达到94.43%。结论]马铃薯品种费乌瑞它适合海南冬季种植,其最佳播种期、种植密度和栽培方式分别为11月14日、7.5万株/hm2和黑色地膜覆盖栽培。

| Abstract: | Objective] The research aimed to study the adaptability of winter potato and its cultivation technology.Method] Winter potato variety Favorita was used as the trial material to study the effects of different sowing time,planting density and cultivation methods on growth and yield of winter potato in Hainan Province.Result] The results showed that the emergence date was early and its growth period was shorted,with the delay of seeding date.Different seeding dates had significant effect on the yield.The yield was the highest which was grown in November 14th,with the average yield per plot 35.16 kg(19 330.20 kg/hm2) and marketable percentage 92.75%.7.5×104 plants per ha,the optimum planting density,produced average yield per plot 20.53 kg(23 108.10 kg/hm2) and marketable percentage 97.08%.Black plastic film mulching advanced emergence and improved emergence rate,with the average yield per plot 20.31 kg(22 333.50 kg/hm2) and marketable percentage 94.43%.Conclusion] Favorita is suitable to plant in Hainan,and its optimum sowing time,planting density and cultivation methods respectively are November 14,7.5 ×104 plants per ha and black plastic film mulching. |
