Selection of Year-round High-yield and High-quality Varieties of Rapeseed Flowering Stalk in Erhai Lake Basin
摘要
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.关键词
