摘要:

针对洱海流域农业绿色转型中高值作物种植模式缺乏的问题,为筛选适宜周年种植的优质高产菜用油菜品种,以9个双低甘蓝型油菜品种为供试材料,分别在小春季(2022年11月5日)和大春季(2023年7月1日)开展田间试验,收集并分析其生育期、产量、农艺性状、养分积累及经济效益等指标。结果表明:(1)不同移栽期种植油菜的生育期存在明显差异,相同品种在小春季种植的生育期(123~141 d)比大春季(43~57 d)显著延长66~98 d;(2)小春季菜薹产量(平均20.2 t/hm2)普遍高于大春季(平均 11.5 t/hm2),其中小春季‘硒滋圆2号’(26.3 t/hm2)和‘大地95’(25.2 t/hm2)产量最高,大春季‘大地95’(16.1 t/hm2)产量最高。大春季和小春季产量主要贡献因子分别为叶片数和单薹重;(3)小春季菜薹的单薹重、薹长、薹粗、叶片数等农艺性状均优于大春季,小春季产量主导因子为单薹重(贡献率43.38%),大春季为叶片数(贡献率41.29%);(4)小春季氮、磷积累量显著高于大春季,‘硒滋圆2号’和‘大地95’表现突出,大春季以‘大地95’最佳;(5)经济效益与产量趋势一致,小春季各品种产值均高于大春季,‘大地95’(周年产值27.9万元/hm2)和‘硒滋圆2号’周年产值最高,显著高于其他品种。综合分析表明,洱海流域可以实现油菜薹周年种植,小春季菜薹产量与品质均优于大春季大春季,‘硒滋圆2号’和‘大地95’适宜作为周年推广品种。未来可结合内在品质、抗病性及田间管理优化,进一步完善周年种植技术体系,提升区域农业经济效益与生态效益。

Abstract:

This study aims to explore the year-round high-value cropping model in the Erhai Basin and to screen high-yielding vegetable-use rapeseed cultivars suitable for year-round cultivation, thereby providing support for the development of regional green and high-value agriculture. Nine double-low Brassica napus cultivars were used as experimental materials, and field trials were conducted in the small-spring season (November 5, 2022) and the large-spring season (July 1, 2023). Data on growth period, yield, quality, and nutrient accumulation were collected and analyzed. The results showed that the growth period of vegetable-use rapeseed differed significantly between seasons, with the small-spring season being 66-98 days longer than the large-spring season. The yield of rapeseed flowering stalk was generally higher in the small-spring season than in the large-spring season, with ‘Xiziyuan No.2’ (26.3 t/hm2) and ‘Dadi 95’ (25.2 t/hm2) having the highest yields in the small-spring season, while ‘Dadi 95’ (16.1 t/hm2) had the highest yield in the large-spring season. The main yield-contributing factors were leaf number (41.29%) in the large-spring season and single-stalk weight (43.38%) in the small-spring season. Agronomic traits such as single-stalk weight, stalk length, stalk diameter, and leaf number were all superior in the small-spring season compared with the large-spring season. The grading results of rapeseed flowering stalks showed that the proportion of first-grade stalks was consistent with the yield performance. Nitrogen and phosphorus accumulation were significantly higher in the small-spring season than in the large-spring season, with the superior cultivars being ‘Xiziyuan No.2’ and ‘Dadi 95’, while ‘Dadi 95’ performed best in the large-spring season. Comprehensive analysis indicated that year-round cultivation of vegetable-use rapeseed can be achieved in the Erhai Basin, with higher yield and quality in the small-spring season compared with the large-spring season. ‘Xiziyuan No.2’ and ‘Dadi 95’ showed outstanding performance and are suitable for annual promotion, providing technical support for the development of local green and high-value agriculture.
