尿素及光合菌肥对韭菜生长和品质的影响

Effect of Urea and Photosynthetic Bacterial Fertilizer on the Growth and Quality of Chinese Chive

以"791"韭菜品种为试材,研究了尿素和光合菌肥不同配施对韭菜生长发育和品质的影响。结果表明,适量尿素和光合菌肥配合施用有促进韭菜的生长和改善品质的作用。其中,菌肥稀释200倍和10kg/667m2尿素混施处理时,韭菜叶绿素a、叶绿素b和干鲜比最高,可溶性糖、可溶性蛋白和Vc含量极显著高于对照,并且硝酸盐和粗纤维的含量均显著低于对照。

Chinese chive ＂791＂ was used as the experimental material. The effect of different concentrations ot urea and photosynthetic bacterial fertilizer on growth and quality of Chinese chive was studied. The results showed： appropriate use of urea and photosynthetic bacterial fertilizer played an important role in improving growth and quality of Chinese chive. When photosynthetic bacterial fertilizer 200×and urea 10 kg/667m^2 were used together, Chlorophyll a, Chlorophyll b, ratio of dry and fresh weight were the max compared to control, and the content of Soluble sugar, soluble protein and Ve was very significantly higher than control, but the content of nitrate and crude fiber was significantly lower compared to control respectively.
