摘要
以商品薯合作88号为试材,在施肥总量相同基础上,于马铃薯现蕾后分别进行叶面喷施清水(CK)、0.5%尿素溶液(T1)、0.3%磷酸二氢钾溶液(T2)及0.5%尿素+0.3%磷酸二氢钾溶液(T3),研究叶面追肥对马铃薯农艺性状及产量的影响。结果表明:不同处理对马铃薯出苗动态、干物质积累、植株形态及产量形成产生了影响。其中T1处理的出苗率、干物重、株高、茎粗及叶面积指数不同程度大于其他处理;T2处理的分枝数、单株结薯数、单株鲜薯重及商品薯比率最多;T3处理的小区产量最高。
In the present study, the commercial potato HeZuo-88 was used to investigate the effects of toliage spray on the yield and agronomic traits, which including foliar spraying water （CK）, foliar application 0.5% urea solution （T1）, foliar application 0.3% potassium dihadrogen phosphate solution （T2）, foliar application 0.5% urea and 0.3% potassium dihadrogen phosphate solution （T3） Mter squaring , all of which were treated by applying equal amount fertilizer.The result showed that different treatments had effect on the germination trend, dry matter accumulation, plant agronomic traits and yield of potato. Among the four treatments, the best growth of plant was T1, which seedling germination rate, dry weight, plant height, stem diameter and leaf area index were higher than other treatments. The branch number, tuberization rate, fresh tuber weight and commodity rate per plant were the best for T2. The plot yield was the highest for T3.
