The greenhouse vegetable is a very important agricultural product in China. However, some improper farming operations and long-term continuous cropping may lead to a series of vegetable greenhouse problems such as reduced soil tilth, serious pests and diseases, and agricultural non-point source pollution, which affect the sustainable development of vegetable greenhouse industry. Based on the main obstacle factors of typical vegetable greenhouses in Shouguang City, Shandong Province, the commonly used green environmental protection improvement methods are selected and the improvement effects are evaluated. The results show that the soil improvement measures which combine deep soil vibration breaking and ethanol disinfection can improve soil physical and chemical properties, eliminate deep soil compaction and surface soil salt accumulation, mitigate the environmental risk of nitrate nitrogen and inorganic phosphorus pollution, and reduce the possibility of diseases and insect pests; deep soil vibration breaking and indigenous microorganisms(specially cultivated by non-heated contact method under the environment of 80～90 ℃, invention patent number CN110684540 A) fermentation method mixed cultivation treatment can also increase the number of beneficial microorganisms in the soil and increase its activity. The research proves that 30 days after taking the above improvement measures, the soil physical and chemical properties have been improved significantly, which is beneficial to the growth of crops, and the problems of pests and diseases have been significantly alleviated, which provides a direct basis for the improvement of the soil in vegetable greenhouses using Pro-Soil online mode.
