摘 要:为加快马铃薯新品种的示范推广及皖北地区马铃薯品种的更新换代,2019—2020年联合安徽省农业科学院园艺研究所引进了12个马铃薯品种,并以费乌瑞它为对照,在阜南县开展了不同品种比较试验。结果表明:不同品种的生育期、农艺性状及产量存在很大差异,其中徽薯5号、N190长势好且整齐,产量和商品率较高,分别较对照费乌瑞它增产45.2%和20.7%,适宜在阜南地区推广种植。

Abstract: To speed up the demonstration and extension of new potato varieties and the replacement of potato varieties in northern Anhui. From 2019 to 2020, the project team, together with the Institute of Horticulture, Anhui Academy of Agricultural Sciences, introduced 12 potato varieties, and carry out a comparative screening test of different varieties in Funan County. The potato variety Favorita was set as the control. The results showed that the growth period, agronomic traits and yield of different varieties were quite different. Among them, Huishu No.5 and N190 grew well, and their yield were also higher, increased by 45.2% and 20.7% respectively than control. In addition, the commodity rate of these Huishu No.5 and N190 were also higher than other varieties. In summary, Huishu No.5 and N190 were suitable for large-scale planting in Funan county.

马铃薯是我国继小麦、水稻和玉米之后的第四大栽培作物。近年来,随着马铃薯主食化战略的深入推进,阜南县马铃薯种植规模越来越大。但由于诸多原因,阜南县马铃薯生产的主导品种结构单一,更新换代速度慢,再加上农药、化肥施用不合理以及多年连作的影响,造成马铃薯产量和品质逐年下降。为筛选出适宜阜南地区气候条件和栽培模式的新品种,加快当地品种更新换代,进一步提高马铃薯的生产效益,依托安徽省农业科学院马铃薯创新团队,笔者引进了12个马铃薯新品种,对其生产性状进行田间鉴定,同时综合分析其生产特性,以筛选出适宜阜南地区种植的马铃薯新品种,为进一步提高马铃薯生产效益、扩大马铃薯种植面积提供品种支撑。

1 材料与方法

1.1 试验地概况 试验于2019年12月至2020年5月开展。试验地位于阜南县赵集镇刘大郢村,试验田块为连续种植辣椒等蔬菜多年的大棚地,土质为沙姜黑土,肥力中等偏上。……
