| 中文摘要: |
| 为了丰富菏泽地区冬季蔬菜的种类，增加市场供给，进行淮南黄心乌引种试验，研究不同播
种期对淮南黄心乌农艺性状、单株产量和营养品质的影响，不同施肥处理对其单株产量和营养品质的影响，
移栽苗龄对其缓苗时间和单株产量的影响。结果表明：随着播种期的推迟，株高、株幅、叶片长、叶片宽、
叶柄长和单株产量呈现先降低后增加的趋势，叶柄宽、叶片数呈现先增加后降低再增加的趋势，可溶性糖
呈现先升后降的趋势，蛋白质呈下降趋势，硝酸盐和Vc 无明显变化规律；在8 月25 日、9 月5 日播种，
黄心乌单株产量、蛋白质含量极显著高于其他播种期，单株产量分别为511.16、500.08 g，蛋白质含量分
别为6.27、6.50 mg/g，且硝酸盐含量较低，分别为342.87、357.66 mg/kg，9 月5 日播种，黄心乌Vc 含量
为32.34 mg/100g，显著优于其他播种期。有机肥（O）、有机肥+ 氮肥（ON）、有机肥+ 复合肥（OM）
处理单株产量、可溶性糖和蛋白质显著优于不施肥对照，OM 处理单株产量、蛋白质含量最高，分别为
520.15、6.79 mg/g，但是硝酸盐显著低于ON 处理。6 叶、8 叶期苗龄缓苗时间较短，为4 d，且单株产量较高，
分别为518.72、519.06 g。从农艺性状、单株产量、营养品质综合分析，淮南黄心乌在菏泽的最佳播种时
间为8 月25 日至9 月5 日，最佳施肥处理为有机肥+ 复合肥，最佳移栽苗龄为6~8 叶期。 |

| In order to enrich vegetable species and supply of the market requirement in early winter and
winter, Brassica campesttris L.ssp.chinesis (L.) Makino var rosularis Tsen et Lee was introducted to Heze region.
This experiment was mainly to explore the effects of different seeding times on its agronomic characters, yield and
nutritive quality, the effects of different fertilization on its yield and nutritive quality, and the effects of different leaf
ages of transplantation on yield and slow seeding time. The result showed that as the seeding times delayed, plant
height, plant width, leaf length, leaf width, petiole length and yield of single plant showed a trend of declining initially
and then increasing, petiole width, leaf number and soluble sugar showed a trend of increasing initially followed by
declining, but, except soluble sugar, then again increasing, protein content showed a trend of declining, but Vc and
nitrate content had no obvious change rules. Yield and protein contents were significantly higher in August 25th and
September 5th than the other seeding times, the yields of single plant were 511.16 g, and 500.08 g, respectively, protein contents were 6.27 mg/g and 6.50 mg/g, respectively, nitrate contents were 342.87 mg/kg and 357.66 mg/
kg, respectively. Vc content was significantly higher in September 5th than the other seeding times, with its content
reaching 32.34 mg/100g. The treatments of organic fertilizer (O), organic fertilizer adding nitrogenous fertilizer (ON),
organic fertilizer adding compound fertilizer (OM) were significantly higher than CK (no fertilizer) in single plant yield,
soluble sugar content and protein content. The single plant yield and protein content of OM were the highest, reaching
520.15 g and 6.79 mg/g, respectively, but its nitrate content was significantly lower than ON. Seeding age of 6 to 8
leaves plant was shorter with 4 days, but had higher single plant yield, with 518.72 g and 519.06 g, respectively. From
comprehensive analysis of agronomic characters, yield and nutritive quality, it concluded that the best seeding time of
B. campesttris was from August 25th to September 5th in Heze. Organic fertilizer adding compound fertilizer was the
optimal fertilizer combination, and the optimal seeding age was 6 to 8 leaves age. |
