| 摘 要： | 将沼渣有机肥与不同比例的化肥配制成不同配方的沼渣复混肥,用作为小白菜生长的基肥。通过对小白菜生长指标及品质的比较,分析不同配方沼渣复混肥对小白菜生长和品质的影响,选出适合小白菜生长并提高其品质的复混肥配方。结果表明,E处理小白菜VC含量为1.582 8 mg/g,可溶性糖含量为42.34%,硝酸盐含量为77.86 mg/kg,叶绿素SPAD值为50.33,更有利于小白菜的生长和品质的改善。

| Abstract: | Different formulas of biogas residues compound fertilizer made from biogas residues organic manure and different proportion of fertilizer will be used as basic fertilizer of pakchoi growth.Based on the change of pakchoi growth index and quality,the effect of different formulas of biogas residues compound fertilizer on the growth and quality of pakchoi is analyzed,and the optimum compound fertilizer formula to improve the growth and quality of pakchoi is obtained.The results showed that: pakchoi VC content of E treatment is 1.582 8 mg/g,content of soluble sugar 42.34%,nitrate content 77.86 mg/kg,SPAD of chlorophyl 50.33,which is more conducive to the growth and quality improvement of pakchoi. |
