适宜豫北地区棉豆轮作的荷兰豆品种与播期筛选

旨在筛选适宜豫北地区与夏棉轮作的冬茬荷兰豆品种和播期。以18个国内外的荷兰豆品种为试材,用田间调查方法测得12个性状的数据,并研究了其中4个品种在2个播期下的差异。结果表明,2019年种植的所有参试荷兰豆品种均安全越冬;早播（10月19日）比晚播（10月29日）能提早结荚并提升株高、单荚重和鲜荚产量;通过比较发现了每个荷兰豆品种所具有的特点,其中‘美国581’鲜荚产量高达25088.24 kg/hm²,而且其他农艺性状优良,是参试品种中最适宜引种豫北棉区的荷兰豆品种。该试验初步筛选出了适宜豫北地区越冬栽培的荷兰豆品种及其播期,为本地区研究“棉花-荷兰豆”双季栽培模式奠定了基础。

Snow Pea Varieties and Sowing Dates: Suitable for Cotton-Pea Rotation in Northern Henan Province

To select the varieties and sowing dates of snow pea suitable for "Cotton-Snow pea" rotation in the north of Henan Province, 12 characters of 18 snow pea varieties from domestic and abroad were explored by field investigation method, and the differences of four varieties between two sowing dates were studied. The results showed that all the varieties planted in 2019 survived through winter. The early sowing date (October 19^th) of snow resulted in earlier pod set and improved plant height, single pod weight and fresh pod yield, compared with the late sowing date (October 29^th). Moreover, the characteristics of each variety were observed, among which the fresh pod yield of "US 581" could reach 25088.24 kg/hm², and its other agronomic characters were excellent, indicating that the variety was the optimal one to be introduced into the cotton area of northern Henan Province. In this experiment, the varieties and the sowing dates of snow beans suitable for overwintering cultivation in northern Henan were preliminarily selected, which could be conducive to studying the double cropping cultivation mode of "Cotton-Snow pea" in this area.
