蚓粪和益生菌互作对土壤性状、菠菜产量和品质的影响

选取两种益生菌(巨大芽孢杆菌和解淀粉芽孢杆菌)分别与化肥和蚓粪配施,研究了蚓粪和益生菌配施对设施蔬菜地土壤化学性状、酶活性及菠菜产量和品质的影响。结果表明:在等养分条件下与单施化肥相比,蚓粪能够显著提高土壤有效磷含量及p H值,降低速效钾、铵态氮含量及EC值,有利于土壤脲酶、蛋白酶和过氧化氢酶活性的提高,有效改善菠菜品质;与单施蚓粪相比,益生菌与蚓粪配施不仅显著提高土壤硝态氮含量、蔗糖酶活性,还增加了土壤EC值,提高了菠菜可溶性糖、蛋白及维生素C含量,且解淀粉芽孢杆菌配施蚓粪还增加了菠菜产量;而益生菌配施化肥对菠菜产量增加和品质改善效果不及益生菌配施蚓粪效果显著。综合比较两种益生菌和蚓粪配施效果,以蚓粪配施解淀粉芽孢杆菌对土壤性状改善和蔬菜产量、品质提高效果最好。

Effect of vermicompost and probiotics interaction on yield and quality of spinach and soil properties

In this study, the effect of two probiotic ( Bacillus megaterium and Bacillus amyloliquefaciens) combined with mineral fertilizer and vermicompost on soil properties, spinach yield and quality was investigated. The results showed that, under the same nutrient level, vermicompost significantly improved the content of soil available phosphorus and pH value, reduced the content of available potassium, ammonium nitrogen and EC value, increased the activities of favorable soil ure-ase, protease and catalase, effectively improved the quality of spinach. Compared with the single application of vermicom-post, probiotics with vermicompost fertilizer not only significantly increased soil nitrate content and invertase activity, but al-so increased the soil EC value, the spinach soluble sugar, protein and vitamin C content. Bacillus amyloliquefaciens com-bined with vermicompost also increased the yield of spinach. This improving efficiency was better than chemical fertilizers combined with probiotics. By comprehensive comparison of effects of the two kinds of probiotics and vermicompost, vermi-compost with applied solution of Bacillus amyloliquefaciens had the best effect on soil properties improvement and vegetable yield and quality.
