摘要: [目的]明确自行研制的两种不同养分的含Bacillus amyloliquefaciens SQR9复合微生物液体肥料对玉米和白菜的促生效果,以期为新型生物水溶肥料的推广应用提供理论与实践指导。[方法]试验以玉米和白菜为供试材料,共设9个处理:灌施清水处理(CK)、灌施养分含量为100 g.kg-1的化肥处理(CF1)、灌施养分含量为100 g.kg-1的不添加Bacillus amyloliquefaciens SQR9的其他配方一样的对照水溶肥料处理(AA1)、灌施存储3个月后的养分含量为100 g.kg-1的含Bacillus amyloliquefaciens SQR9复合微生物液体肥料处理(AAS1-1)、灌施现配的养分含量为100 g.kg-1的含Bacillus amyloliquefaciens SQR9复合微生物液体肥料处理(AAS1-2)、灌施养分含量为200 g.kg-1的化肥处理(CF2)、灌施养分含量为200 g.kg-1的不添加Bacillus amyloliquefaciens SQR9的其他配方一样的对照水溶肥料处理(AA2)、灌施存储3个月后的养分含量为200 g.kg-1的含Bacillus amyloliquefaciens SQR9复合微生物液体肥料处理(AAS2-1)、灌施现配的养分含量为200 g.kg-1的含Bacillus amyloliquefaciens SQR9复合微生物液体肥料处理(AAS2-2)。[结果]盆栽试验结果表明,不论是在总养分100 g/kg施肥水平下,还是在总养分200 g/kg施肥水平下,相比于不添加Bacillus amyloliquefaciens SQR9的其他配方一样的对照水溶肥料处理、化肥和空白对照,含Bacillus amyloliquefaciens SQR9复合微生物液体肥料更能够促进玉米和白菜的生长,提高其生物学性状,但储存3个月后的和现配的含Bacillus amyloliquefaciens SQR9复合微生物液体肥料在玉米和白菜的生物学性状方面均无显著性差异;根际土壤中芽孢杆菌数量的测定结果表明,含功能菌复合微生物液体肥料的施用能够提高根际土壤中芽孢杆菌的数量。[结论]根部灌施含Bacillus amyloliquefaciens SQR9复合微生物液体肥料可以有效促进玉米和白菜的生长。

Abstract: [Objective] This study aimed at evaluating the plant growth promotion effect of two different compound microbial liquid fertilizers containing Bacillus amyloliquefaciens SQR9 on maize and cabbage for providing the theoretical and technical base for the popularization and application of the novel products.[Method] Pot experiments were performed with nine treatments: fertigation of water (CK), fertigation of water soluble chemical fertilizer containing 100 g·kg-1 nutrients (CF1), fertigation of water soluble fertilizer containing 100 g·kg-1 nutrients without Bacillus amyloliquefaciens SQR9 (AA1), fertigation of compound microbial liquid fertilizer containing 100 g·kg-1 nutrients and Bacillus amyloliquefaciens SQR9 after 3 months of storage (AAS1-1), fertigation of freshly produced compound microbial liquid fertilizer containing 100 g·kg-1 nutrients and Bacillus amyloliquefaciens SQR9 (AAS1-2); fertigation of water soluble chemical fertilizer containing 200 g·kg-1 nutrients (CF2), fertigation of water soluble fertilizer containing 200 g·kg-1 nutrients without Bacillus amyloliquefaciens SQR9 (AA2), fertigation of compound microbial liquid fertilizer containing 200 g·kg-1 nutrients and Bacillus amyloliquefaciens SQR9 after 3 months of storage (AAS2-1), fertigation of freshly produced compound microbial liquid fertilizer containing 200 g·kg-1 nutrients and Bacillus amyloliquefaciens SQR9(AAS2-2). [Result]Pot experiment results showed regardless of the nutrient amounts, compared with water soluble fertilizer without Bacillus amyloliquefaciens SQR9, water soluble chemical fertilizer and the blank amended with water, the compound microbial liquid fertilizer containing Bacillus amyloliquefaciens SQR9 efficiently promoted maize and cabbage growth by improving their biological characters. No significant difference in the biological characters of maize and cabbage was observed between the water soluble fertilizers containing amino acids and Bacillus amyloliquefaciens SQR9 freshly produced and stored for 3 months; and application of water soluble fertilizer containing functional microbes increased the number of Bacillus in rhizosphere soil. [Conclusion]The compound microbial liquid fertilizer containing Bacillus amyloliquefaciens SQR9 effectively promoted the growth of maize and cabbage by root irrigation.
