摘要: 以龙薯9号、心香和普薯32号为试验材料,探究豆-薯-麦三熟制下种植密度对不同甘薯品种农艺性状及产量的影响。结果表明,三熟制下品种特性是决定甘薯品种农艺性状及产量的关键因素,种植密度对甘薯品种的地上部农艺性状无显著影响,对甘薯产量影响显著。其中,心香在60 000株/hm2的种植密度下产量和经济效益最高,分别为18 706.44 kg/hm2和16 901元/hm2;龙薯9号在67 500株/hm2的种植密度下产量和经济效益最高,分别为29 939.88 kg/hm2和9 568元/hm2;普薯32号在60 000株/hm2的种植密度下产量最高,为18 706.44 kg/hm2,但经济效益为负。在江汉平原豆-薯-麦三熟制下,甘薯品种心香在种植密度为60 000株/hm2的产量和经济效益最高。

Abstract: In order to explore the effects of planting density on agronomic traits and yield of different sweet potato varieties, the field experiment was conducted using sweet potato varieties of Longshu No.9, Xinxiang, Pushu No.32. Results showed that the variety characteristics were the key factors that determine the agronomic traits and yield of sweet potato varieties. Planting density had no significant impact on the above-ground agronomic traits of sweet potato varieties, but had a significant impact on sweet potato yield. Among them, Xinxiang had the highest yield and economic benefits at a planting density of 60 000 plants/hm2, which were 18 706.44 kg/hm2 and 16 901 yuan/hm2, respectively; Longshu No.9 had the highest yield and economic benefits at a planting density of 67 500 plants/hm2, which were 29 939.88 kg/hm2 and 9 568 yuan/hm2 respectively; Pushu No.32 has the highest yield at a planting density of 60 000 plants/hm2 which was 18 706.44 kg/hm2, but the economic benefits was negative. Therefore, the sweet potato variety Xinxiang under the bean-potato-wheat three-cropping system could have the highest yield and economic benefits at a planting density of 60 000 plants/hm2 in Jianghan plain.
