蚯蚓粪与鼠李糖脂配施对小白菜和生菜产量、生长指标及品质的影响

Effects of vermicompost and rhamnolipid on soil enzyme activities and microbial community structure

为了探明蚯蚓粪配施鼠李糖脂对小白菜及生菜品质的影响,基于盆栽试验,研究了蚯蚓粪及其与鼠李糖脂(0.027%、0.054%和0.108%)配施处理对小白菜和生菜产量、生长指标和品质指标的影响。结果表明,蚯蚓粪与鼠李糖脂配施可以不同程度地提高小白菜及生菜品质,相比不施肥处理蚯蚓粪配施鼠李糖脂处理小白菜及生菜的产量、叶面积、可溶性糖、可溶性蛋白和可滴定酸均显著提高。蚯蚓粪配施鼠李糖脂处理小白菜和生菜产量、可溶性糖、可溶性蛋白、可滴定酸及硝酸盐含量与蚯蚓粪处理无显著性差异。随着鼠李糖脂浓度的增大,蚯蚓粪配施鼠李糖脂处理的小白菜产量呈现下降趋势,未达到显著性差异。蚯蚓粪配施鼠李糖脂相比蚯蚓粪处理可显著提高小白菜游离氨基酸含量。综上,蚯蚓粪配施鼠李糖脂具有显著提高蔬菜产量的效果,蚯蚓粪配施鼠李糖脂与蚯蚓粪处理对蔬菜产量及品质方面的影响没有显著性差异,二者配施没有降低蚯蚓粪的肥效,说明蚯蚓粪与鼠李糖脂配施具有药肥开发的可行性。

To investigate the effects of vermicompost with rhamnolipid on the quality of cabbage and lettuce,by investigate the effects of vermicompost and rhamnolipid(0.027%,0.054%and 0.108%)on the yield,growth and quality of cabbage and lettuce based on pot trials.The results showed that the application of vermicompost with rhamnolipid improved the quality of cabbage and lettuce to different degrees,and the yield,leaf area,soluble sugar,soluble protein and titratable acid of cabbage and lettuce were significantly higher in the vermicompost with rhamnolipid treatment compared to the nofertilizer treatment.Yield,soluble sugars,soluble protein,titratable acid and nitrate content of cabbage and lettuce were not significantly different between the vermicompost and rhamnolipid treatments.As the concentration of rhamnolipid increased,the yield of cabbage in the vermicompost treatment with rhamnolipid showed a decreasing trend,but did not reach a significant difference.The vermicompost treatment with rhamnolipids significantly increased the free amino acid content of cabbage compared to the vermicompost treatment.To sum up,the combination of earthworm manure and rhamnolipids has a singnifican effect on improved vegetable yield,there was no significant difference in the effect of vermicompost with rhamnolipid and vermicompost on the yield and quality of vegetables,and the effectiveness of vermicompost was not reduced by the two treatments,indicating that the combination of earthworm manure and rhamnolipids has the feasibility of drug fertilizer of drug fertilizer development.
