Abstract Adopting substrate cultivation and brick cultivation，by setting different brick hole
densities（ 0，6，12 and 18 holes） in bricks，the paper studied their effect on tomato（Lycopersicon
esculentum Mill.） growth. The results showed that the tomato yield under brick cultivation with 18，12，
6 brick holes and without brick holes compared with substrate cultivation increased 27.63%，30.84%，
23.38% and 24.65%，respectively．Meanwhile，the production input was low．Compared to the substrate
cultivation，brick cultivation could improve tomato plant height，stem diameter，leaf blade num -
bers，leaf dry weight，stem dry weight，root dry weight，fruit yield，and nutrient solution utilization
efficiency．Applying brick cultivation into modernized agricultu ral production is quite feasible.
