Abstract: In order to invest the dynamic effects of fertilization on the chemical properties of cucumber soils, and provide theoretical support for fertilization in greenhouse, two vegetable greenhouses were set up as research objects, which were located in Jingmen City, Hubei Province. In the experiment, different kinds of fertilizers were used to study the changes of soil chemical properties within 14 days after fertilization and profile soil. The results showed that soil surface acidification was significant in the greenhouse, and the nutrient content gradually decreased with the increase of soil depth in the range of 0-100 cm. Soil microbial biomass carbon(SMB-C), Ammonium nitrogen and Soil microbial biomass nitrogen(SMB-N) showed the same trend in the observation period of shed A and B. And they all reached the first peak at the 2nd day after fertilization(SMB-C in B greenhouses reached the first peak at the 3rd day after fertilization). The content of ammonium nitrogen were the highest after two days of fertilization in the two greenhouses, and the content of ammonium nitrogen and nitrate nitrogen increased first and then decreased during the whole observation period. It could be seen that the fertilizer effect was the most significant on the 2nd day after fertilization by observing the changes of soil chemical properties. There was a dynamic relationship between the change of soil alkaline nitrogen content and fertilizer application for a period of time, but with the increase of fertilization time, it would return to the state of non-fertilization. It was found that the chemical properties were gradually recovered to the level of non-fertilization by observing the monitoring results for 14 days. Therefore, the next monitoring period could be lengthened to provide a theoretical basis for the rational formulation of the fertilization cycle.
