| 摘 要： | 研究利用植物促生菌提高肥料效率以部分替代化肥。采用大田试验结合连续盆栽试验的方法,以100%化肥(CF)为对照,设置如下处理:75%化肥配施普通有机肥(OF)或木霉微生物肥(BF)或木霉孢子悬液(SS)。结果表明,75%化肥配施以一定量(每株50 g)木霉微生物肥可维持田间番茄稳产,与100%化肥处理产量相当;而与普通有机肥或木霉孢子悬液灌根配施则会显著降低番茄产量,连续栽种4季后,产量下降35%以上。此外,BF处理可显著提高番茄果实的品质,与CF相比,总可溶性糖和维生素C含量分别提高35%~54%和2%~23%,而硝酸盐积累量下降32%~46%。究其原因,BF处理中木霉功能菌的有效定殖促进了番茄根际细菌、真菌、放线菌的增殖,土壤养分的有效性显著提高,表现为根际微生物数量与多项土壤肥力指标呈显著相关关系。综上,木霉微生物肥与减量化肥配施,可有效保证番茄稳产,提高番茄品质,长期施用还可提高土壤微生物数量、改善土壤肥力。
