摘      要：The micro-sprinkler irrigation mulched(MSM)has been suggested as a novel water-saving approach in con-trolled environment ***,the effects of microbial community structure and enzyme activity in the rhizosphere soil on crop growth under MSM remain *** study conducted a randomized experimen-tal design using greenhouse tomatoes to investigate changes in bacterial community structure and enzyme activity in rhizosphere soil under different irrigation frequencies(F)and amounts(I)of ***findings revealed that with the increase of F or I,The total count of soil bacteria in tomatoesfirst rose and then fell in terms of Opera-tional Taxonomic Units(OTUs)classifi*** to other F,the most abundance of nitrogen and phos-phorus metabolism genes and enzyme activities were observed with a 5-day ***,the diversity of soil bacterial community structure initially rose before eventually declining with the increase of the *** 1.00 Epan(cumulative evaporation of a 20 cm standard pan)under MSM helped boost the abundance of nitrogen and phosphorus metabolism functional genes in soil bacteria,ensuring higher enzyme activities related to nitro-gen,carbon,and phosphorus metabolism in the rhizosphere soil of ***’yield initially rose before eventually declining with the increase in F or I,whereas I had a more significant effect on yield.A 1.00%increase in I yielded a minimum of 39.24%increase in tomato *** study showed a positive correlation between soil bacterial community,soil enzyme activity,and greenhouse tomato yield under *** the results comprehensively,the combined irrigation mode of F of 5 d and I of 1.00 Epan was recommended for greenhouse tomatoes under *** conclusion provides theoretical support for water-saving practices and yield improve-ment in facility agriculture,especially tomato cultivation.
