不同基质拮抗菌发酵液处理对香蕉幼苗养分吸收的影响

为研究复合拮抗菌发酵液对香蕉植株养分吸收的作用，在盆栽条件下，以麦麸、豆饼、花生饼、菜籽饼、芝麻饼、花椒饼为发酵基质，分别研究添加拮抗菌(4-L-16、T3-G-59)和不添加拮抗菌的发酵液对香蕉幼苗地上部氮、磷、钾、钙、镁积累量的影响。结果表明：不同饼肥液体发酵液均可有效提高香蕉对氮、磷、钾、钙、镁的吸收。发酵液中添加拮抗菌可进一步提高香蕉对磷、钾、镁的吸收利用，但对氮、钙的吸收无显著地促进作用。豆饼、菜籽饼、花生饼可作为拮抗菌4-L-16、T3-G-59理想的发酵基质。

Effects of Different Substrates of Antagonistic Bacteria Fermentation Liquid Treatmentson Nutrient Absorption of Banana Seedlings

The objective of this study is to investigate the nutrient absorption effects of compound fermentation liquid adding antagonistic bacteria 4-L-16 and T3-G-59 into 6 substrates on banana seedling. The effect fermentation liquid with antagonistic bacteria (4-L-16, T3-G-59) and without antagonistic bacteria (4-L-16, T3-G-59) on N, P, K, Ca, Mg accumulation of banana seedlings were analyzed under the potted condition. The results showed that all kinds of the fermentation liquids produced from different substrates played positive roles on the absorption of N, P₂O₅, K₂O, Ca, Mg. Further more, the fermentation liquid with the antagonistic bacteria added in them had much more significant effects on the absorption of P₂O₅, K₂O, Mg rather than the ones without, but had no significant effects on the absorption of N and Ca. From the experiment we concluded that bean cake, peanut cake or rapeseed cake could be the best fermentation substrates for 4-L-16 and T3-G-59.
