Abstract：The tomato variety “Zhong Yan 998” was used in the spring and autumn greenhouse of Tongzhou experimental station of China Agricultural University from March 2017 to July. A total of 6 treatments were conducted, including 3 irrigation lower limits(calculated with 85%,75%,65% of field water holding ratio)and 2 kinds of trace buried depth gradients(15 cm, 30 cm). The results showed that the influence regularity of buried depth and irrigation lower limit on tomato plant height was not obvious; deep burial treatment was more beneficial to the accumulation of stem dry matter, and the shallow burial was more beneficial to the accumulation of dry matter. Deep burial treatment is more conducive to the accumulation of stem dry matter in plants.Shallow burial is more conducive to the accumulation of dry matter in leaves, which indicates that the transpiration of shallow buried plants is greater. The influence regularity of buried depth and irrigation lower limit on root dry weight is not strong. Deep burial is more beneficial to increasing fruit yield, nitrogen apparent utilization and ferti-lizer partial productivity, and shallow burial is more beneficial to improving water use efficiency; the lower the irrigation limit, the higher the fruit yield, water use efficiency, nitrogen apparent utilization and partial productivity of fertilizer. Therefore, based on the results of this experiment, we can conclude that the depth of the planting is 30 cm, and the lower limit of irrigation is 65% of field water holding ratio which is most suitable for the growth of greenhouse tomatoes under this experimental condition.
