The results showed that total soluble sugar, reducing sugar and sucrose content in pickled leaf mustard were significantly decreased by increasing applied nitrogen, however the soluble protein, nitrate and nitrite content in pickled leaf mustard were increased. 结果表明,增加氮肥量,腌制叶用芥菜的可溶性总糖、还原糖和蔗糖含量显著降低,而其可溶性蛋白质、硝酸盐和亚硝酸盐含量则显著增加;
Accumulation process of dry material of hybrid tumour stem mustard as well as the three big elements absorption rule of nitrogen, phosphorus and potassium during the growth were studied, by means of sampling at given stages, the chemical analysis and the model fitting method. 用分期取样、化验分析、模型拟合的方法,研究了杂交茎瘤芥干物质积累过程以及生长过程中对氮、磷、钾三大元素的吸收规律。
The results indicated that the dry material accumulation of hybrid tumour stem mustard and the absorption of the nitrogen, the phosphorus and the potassium conform to the logistic growth curve. 结果表明,杂交茎瘤芥干物质积累和对氮、磷、钾的吸收均符合Logistic生长曲线。
The soluble protein content in two cultivars of leaf mustard was significantly increased when the low dose of nitrogen ( < 100 kg/ ha) was applied. 仅较低施氮量(<100kg/ha)对叶用芥菜可溶性蛋白质含量有明显影响。
Study on biological nitrogen removal in mustard tuber wastewater with high salinity and high nitrogen concentration 高盐高氮榨菜废水生物脱氮试验研究
The chlorophyll a, chlorophyll b, β-carotene, lutein and vitamin A content in two cultivars of leaf mustard were significantly promoted by increasing nitrogen supply, but when the dose of nitrogen was higher than 200 kg/ ha, their contents were stable. 随着氮肥量增加,叶用芥菜的色素物质(叶绿素a、叶绿素b、β-胡萝卜素、叶黄素)和维生素A含量均呈显著的上升趋势,但当氮肥量超过200kg/ha时,其含量变化稳定。
Applied the fermentation agent to kohlrabi and Potherb Mustard fermentation, products from new fermentation technology had stable quality and good taste, and whose total acid, proteins, amino nitrogen and pectic were better than those from natural fermentation. 将其应用于雪里蕻发酵和大头菜发酵,接种发酵新工艺产品的质量稳定,风味好。总酸,蛋白质,氨基酸态氮及果胶等成分的检测结果均优与自然发酵。
Along with the rapid development of mustard industry, a large amount of hypersaline wastewater containing high nitrogen and phosphorus has been discharged into the Three Gorges Reservoir annually. 随着库区特色榨菜产业高速发展,每年向三峡库区排放大量高盐高氮磷废水,随着库区水环境氮磷污染和富营养化的加剧,以及氮磷排放标准的提高,开发高效除磷技术成为当务之急。
