摘  要：
在湖北荆州李埠镇对冬播马铃薯费乌瑞它用"旱立停"抗旱剂设置叶面喷施2次、拌种、叶面喷施1次+拌种、叶面喷施2次+拌种和叶面喷施清水(对照)5种处理,探讨其应用效果.结果表明,"旱立停"能显著缩短出苗时间,增加株高,增加单穴块茎数,并对块茎重有促进作用;施用抗旱剂能够显著提高产量,产量为喷施两次+拌种>喷施2次>叶面喷施1次+拌种>拌种>对照处理,但商品薯率低于对照;在试验中,喷施两次+拌种和喷施2次两处理的产量分别为25 546.0 kg/hm2、24 701.4 kg/hm2,显著高于其他处理,叶面喷施1次+拌种的商品薯产量为21 145.7 kg/hm2,极显著高于其他处理.

摘  要：
The effect of a drought-resistant agent,ASA,on Favorite,one cultivar of potatoes sowed in winter,was conducted in Lifu town,Jingzhou city,Hubei province.There were 5 ASA treatments: foliar spraying twice,seed dressing,foliar spraying once and seed dressing,foliar spraying twice and seed dressing,and foliar spraying water.The results showed that ASA could significantly shorten the emergence time,increase the plant height and the number of tubers per hole.And it was likely to promote tuber weight.Application of ASA could significantly increase the yield of Favorite.The yield of the treatment of foliar spraying twice and seed dressing was the highest,followed by that of foliar spraying twice,seed dressing and the yield of the control was the lowest.But the commercial potato rate decreased when treated with ASA.The yield of the treatment of foliar spraying twice and seed dressing and that of the treatment of foliar spraying twice were 25 546.0 kg / hm2 and 24 701.4 kg / hm2 respectively,significantly higher than that of other treatments.The yield of commercial potato of the treatment of foliar spraying once and seed dressing was 21 145.7 kg / hm2,which was significantly higher than that of other treatments.
