    摘要:

    研究叶面喷施含Bacillus amyloliquefaciens SQR9复合微生物液体肥料在辣椒和白菜上的应用效果,以期开发出根际有益微生物新的应用模式和新的叶面肥产品。以辣椒和白菜为供试材料,设以下6个处理评估肥料效果:喷施清水处理(CK)、喷施与复合微生物液体肥料等养分的化肥处理(CF)、喷施含化肥+氨基酸+糖蜜的水溶肥处理(T1)、喷施含化肥+氨基酸+糖蜜+微量元素的水溶肥处理(T2)、喷施含化肥+氨基酸+糖蜜+SQR9的水溶肥处理(T3)和喷施含化肥+氨基酸+糖蜜+微量元素+SQR9的复合微生物液体肥料处理(T4)。盆栽试验结果表明,与其他5个处理(CK、CF、T1、T2、T3)相比,T4处理在各项促生指标上虽未全部达到显著性差异,但其更能够促进辣椒和白菜的生长,提高其生物学性状。可培养微生物数量上,新型含菌株SQR9复合微生物液体肥料的喷施,增加了叶际芽孢杆菌的数量;与喷施清水对照(CK)和与复合微生物液体肥料等养分的化肥处理(CF)相比,其他4个处理(T1、T2、T3、T4)对辣椒和白菜叶际可培养微生物数量影响更大,而喷施含Bacillus amyloliquefaciens SQR9复合微生物液体肥料(T4)的影响更为明显。叶面喷施含Bacillus amyloliquefaciens SQR9复合微生物液体肥料可有效促进辣椒和白菜的生长。

    Abstract:

    This research aims to study the effects of foliar spraying of compound microbial liquid fertilizer containing Bacillus amyloliquefaciens SQR9 on the plant growth for developing a novel application mode of plant growth-promoting rhizobacteria and a novel foliage liquid fertilizer. Pepper and cabbage were selected as the tested model crops, and pot experiments were performed containing 6 treatments: spraying with water (CK), water soluble chemical fertilizer (CF), water soluble fertilizer containing chemical fertilizer, amino acids, and molasses (T1), water soluble fertilizer containing chemical fertilizer, amino acids, molasses, and microelement (T2), water soluble fertilizer containing chemical fertilizer, amino acids, molasses, and strain SQR9(T3), liquid compound microbial fertilizer containing chemical fertilizer, amino acids, molasses, microelement, and strain SQR9(T4). Pot experiment results showed that compared to the other five treatments (CK, CF, T1, T2, T3), T4 treatment efficiently promoted pepper and cabbage growth by improving their biological characters; and the results from the number of cultural microbes showed that compared to CK and CF, the other four treatments (T1, T2, T3, T4), after application of strain SQR9 containing fertilizers effectively enhanced the number of Bacillus and led to greater impact on the culturable microbial population in pepper and cabbage phyllosphere with the greatest influence for T4 treatment. In conclusion, the liquid compound microbial fertilizer containing Bacillus amyloliquefaciens SQR9 can effectively promote the growth of pepper and cabbage by foliar spraying.
