Abstract:
Taking fermented tomato straw as the test materials，the differences of adding fermented tomato straw on the growth of tomato plants，soil physicochemical and soil microbial communities were studied under four treatments including blank soil (TCK)，adding fermented tomato straw (TT)，conventional fertilization treatment (TS)，and conventional fertilization mixed with fermented tomato straw (TTS) by using pot experiment and high-throughput sequencing technology,in order to provide reference for recycling of vegetable straw.The results showed that TT treatment compared with TCK treatment could significantly increase tomato plant stem thickness，aboveground weight，single plant yield，no significant effect on chlorophyll content；while TTS treatment compared with TS treatment，tomato plant stem thickness，aboveground weight，single plant yield and chlorophyll content were not significantly different.In terms of soil physicochemical indicators，adding fermented tomato straw increased soil organic matter，carbon-nitrogen ratio and available phosphorus，available potassium and other effective nutrient contents significantly；high-throughput sequencing found that there was no significant change in the composition of bacterial and fungal communities among the four treatments，TT treatment compared with TCK treatment，bacterial Shannon diversity increased，fungal community Shannon diversity did not change significantly.The relative abundance of bacterial and fungal communities changed significantly among different treatments.Adding fermented tomato straw can increase tomato yield and aboveground weight，but has no significant effect on increasing plant chlorophyll content.At the same time，it could improve soil fertility capacity，increase soil organic matter，carbon nitrogen ratio,available phosphorus, available potassium and other effective nutrients.The diversity of soil bacteria community increased,and the abundance of some dominant bacteria such as actinomyces increased.Simple retting and fermentation of tomato straw could be added to the cultivated soil as high-quality organic materials to realize recycling of vegetable crop straw.
