Abstract:
In order to study the effects of microbial strains and corn stalk application，which composted using builtin straw bioreactor，on the growth and yield of winter cropping tomato and the environment of solar greenhouse，three treatments were conducted.Straw bioreactor (A microbial agent) with 4 500 kg?(667m2 )-1corn stalk，straw bioreactor degradation of special microbial strain (B microbial agent) with 4 500 kg?(667m2 )-1corn stalk and straw bioreactor (A microbial agent) with 6 000 kg?(667m2 )-1corn stalk.No microbial strain and no corn stalk addition greenhouse was set up as control (CK).The results indicated that compared to CK，all the treatments significantly increased the stem diameter，leaf area and chlorophyll a/b of tomato plant;plant height and yield were significantly higher under A microbial agent with 4 500 kg?(667m2 )-1corn stalk and B microbial agent with 4 500 kg?(667m2 )-1corn stalk than CK，while they were significantly lower under A microbial agent with 6 000 kg?(667m2 )-1corn stalk treatment.The treatment of A microbial agent with 6 000 kg?(667m2 )-1corn stalk significantly increased soil temperature of 0—15 cm layer on October and November，with the soil temperature 17.35 ℃，appeared on 10th October，which was 1.05 ℃ higher than CK.However，the highest effect of soil temperature improving was found under B microbial agent and 4 500 kg?(667m2 )-1corn stalk treatment in December，the soil temperature was 10.30 ℃ and 0.77 ℃ higher than that of CK，appeared on 25th December.The concentrations of CO2 were significantly higher under all the treatments than CK.The biggest concentrations of CO2 ，1 597.0 mg?m-3，was observed in 1th October，which was 614.8 mg?m-3 higher than that of CK，while the lowest，1 015.0 mg?m-3，was observed in 30th December，which was 393.0 mg?m-3 higher than that of CK.
