摘要
以'油苔 929'、'金油薹 1 号'和'中双 11'为材料,苗期分别喷施磷酸二氢钾、萘乙酸和硒肥,研究不同处理对菜油两用油菜农艺性状、产量和品质的影响.结果表明:冬前调查的各项指标均以萘乙酸处理最高,其次是硒肥处理;收获期 3 个品种的株高、角果数、单株产量和一次有效分枝数均以萘乙酸处理最高,磷酸二氢钾处理次之;硒肥处理的菜薹品质最佳,其次为萘乙酸处理;萘乙酸处理下'金油薹 1 号'效益达 4971.78 元/亩,比对照增收 642.32元/亩.菜油两用油菜在苗期喷施萘乙酸效果较好,加施硒肥处理效果更佳.
Abstract
Field experiments were carried out to study the effect of different foliar fertilizer treatments on the agronomic traits,yield,and quality of Brassica napus L.for both vegetable and oil dual-use rape.The seedlings of'Youtai 929','Jinyoutai 1',and'Zhongshuang 11'were sprayed with potassium dihydrogen phosphate,naphthylacetic acid,and selenium fertilizer,and the agronomic traits,yield,and quality were determined.The results showed that the naphthylacetic acid treatment had the highest indexes before winter,followed by the selenium fertilizer treatment.At the harvesting stage,the plant height,number of siliquae,yield per plant,and number of effective branches on the main stem of the three varieties were the highest in the naphthylacetic acid treatment,followed by those in the potassium dihydrogen phosphate treatment.The fresh shoot quality was the best in the selenium fertilizer treatment and the second in the naphthylacetic acid treatment.'Jinyoutai 1'applied with naphthylacetic acid had the highest economic benefit of 4971.78 CNY/667m2,which was 642.32 CNY/667m2 higher than that of the control.The findings suggested that naphthylacetic acid was suitable to be used as the foliar fertilizer for the seedlings of B.napus varieties for both vegetable and oilseed,and the additional application of selenium fertilizer demonstrated better effect.
