Abstract：In order to solve the disposal of organic waste including vinegar and mushroom residues，and
determine the effects of vinegar and mushroom substrate on continuous cropping obstacle soil，this study mixed
vinegar and mushroom residues at the ratio of 1∶3，1∶1 and 3∶1（V∶V） as soil substrate amendments，
and added the continuous cropping obstacle soil with ratios of 1∶10，1∶8 and 1∶5（V∶V）to investigate
their roles on soil physico-chemical properties，soil enzyme activity，plant growth，fruit yield and quality of
cultivated cucumber．The results showed that application of vinegar-mushroom residue substrate amendment had
decreased the soil bulk density，increased the contents of organic carbon and nutrient，pH value，soil aeration
porosity and soil enzyme activity．Comparing with CK，the organic carbon content increased by 26.6%-144.8%．
Contents of total nitrogen，total phosphorus and calcium increased by 12.94%-85.57%，14.89%-43.26% and
13.48%-75.85%，respectively．The increasing amplitudes of alkaline nitrogen and available phosphorus contents
were 6.84%-25.68% and 16.26%-41.55%．Meanwhile，vinegar-mushroom residue substrate amendment had
promoted the absorption and utilization of water and nutrients by cucumber plants，which is beneficial for plant
growth and fruit yield and quality improvement，and also for effectively relieving the soil damage by continuous
cropping．Comparing with CK，the plant dry weight above the ground had increased by 2.45%-40.28%，
of which A2 treatment had the highest fruit yield increase by 19.81%．The results of grey correlation analysis
indicated that comparing with the other treatments，adding vinegar and mushroom residues substrate amendment
（1∶1，V∶V） with the continuous cropping soil at the ratio of 1∶10（V∶V） could significantly improve soil
physico-chemical properties，promote cucumber growth and increase yield．
