Abstract The structural imbalance of microbial communities in soil is one of the important factors for
the occurrence of obstacles for tomato continuous cropping. This article reviewed the changing characteris⁃
tics of microbial communities in soil and the reconstruction techniques in tomato continuous cropping to
study the mechanism of obstacles for tomato continuous cropping and promote the sustainable development
of the tomato industry. The decrease in microbial diversity in soil under tomato continuous cropping and the
structure shift of microbial communities in soil from "bacterial" soil to "fungal" soil are the main reasons for
the occurrence of obstacles for tomato continuous cropping. Rotation and intercropping， grafting， soil disin⁃
fection， and application of organic fertilizer can reconstruct the structure of microbial communities in soil un⁃
der tomato continuous cropping， helping to reduce the harm of obstacles for continuous cropping， especial⁃
ly rotation and intercropping of leguminous crops are more conducive to reducing the harm of obstacles for
tomato continuous cropping. So far， studies have found that functional microorganisms including Arthrobac‑

ter， Bacillus， Pseudomonas， Solirubrobacter， and Trichoderma spp. are beneficial in overcoming obsta⁃
cles for tomato continuous cropping. The development of bio-organic fertilizers combined with organic fertil⁃
izers for reconstructing the microbial communities in farmland soil is a highly promising technical measure
for biological prevention and control of obstacles for continuous cropping. However， how to ensure the colo⁃
nization， survival， and large-scale reproduction of functional microorganisms in the application of bio-organ⁃
ic fertilizers in different environments is an important bottleneck problem that urgently needs to be solved in
this technology.
