Abstract:: Taking wintering solar greenhouse tomato variety ‘Jinpeng 1’ as material，the effect of the amount of built-in straw reactors (T1,T2,T3:1 905,2 857.5,3 810 kg/667m²) on the micro environment of soil and overwintering tomato were studied.The results showed that applied to a different amount of straw could increase soil temperature，the average soil temperature increased 2.1，1.8，0.4℃；T3 reducing the degree of soil salinization was superior to the other treatments，but T1 labor intensity，vigor and yield were better than other treatments.The number of bacteria and actinomycetes showed T1 was better than the other treatments，the number of fungi T1 was higher than the other treatments,built-in straw reactor technology can significantly accelerate the growth rate of overwintering tomato plants，so that the tomato yield increased 17.37%，16.24% and 14.41%，respectively.
