Abstract:: Tomato under over winter growing system was used as materials，treated by fixed-point monitoring and field experiment，rule of dry matter and nutrient of the plant accumulation absorption，the relationship between cluster and dry matter increment and nutrition uptake accumulation in the whole stage of tomato were determinated，the optimized fertilization recommendation in local suitable temperature was put forward in order to supply reference for rational application of fertilizer for over-winter tomato.The results showed that over-winter greenhouse tomato nutrient uptake accumulation showed slowly increase trend.Proportion of nutrients uptake (N-P-K-Ca-Mg) was 35,12,62,33，18 g per plant during growth period.After flushing，dry matter distributed to the fruit by an average of 52%.The most important period of fertilizer within 90-270 days after transplanting.Between No.4 cluster and No.5 cluster，the increment of fruit dry matter accumulation was 2.8 g per plant，between No.5 cluster and No.6 cluster，the increment of fruit dry matter accumulation was the lowest 0.8 g per plant.The low temperature affected the growth of tomato in this phase.
