摘要
为给马铃薯高产栽培提供参考资料,通过盆栽试验研究了不同水分条件对马铃薯产量及水分利用效率的影响。结果表明,当土壤含水量为最大持水量的50%～60%时,马铃薯产量最高,薯块形成和膨大期是费乌瑞它产量形成的需水关键时期。
The pot experiment of potato was conducted to study the effect of different water-supply on its yield and water utilization efficiency and to provide reference for potato cultivation with high yield.The results showed that the potato yield reached the highest when soil water content was 50%～60% of maximum soil water-holding capacity,and the key water requirement stage for potato yield formation was potato-tuber formation stage and expansion stage respectively.
