摘要
以"四季快菜一号"为试材,以华南农业大学农化室叶菜A改良配方为对照(CK),设定沼液添加量为10%、20%、40%、60%、80%,研究了不同沼液添加量对快菜生长和生理特性的影响。结果表明:在营养液中添加一定量的沼液,能明显提高快菜植株的维生素C、可溶性糖、粗纤维和粗蛋白含量,并能提高蔬菜产量,沼液添加量为40%时效果最好,但对粗脂肪和叶绿素相对含量提高并不明显。
‘Fast vegetable No.1’ was used as test materials,leaf vegetable A improved formulation of South China Agricultural University as control,by biogas slurry addition levels were 10%,20%,40%,60%,80%,the influence of different biogas slurry addition on the growth and physiological characteristics were studied.The results showed that add biogas slurry into nutrient solutions could significantly improve vitamin C,soluble sugar content,crude fiber content,crude protein content and could improve production of vegetables,but the improvement of crude fat content and chlorophyll relative content was not significant.The effect was the best with the treatment T3of biogas slurry cultivation.
