Many firms selling the perishable products adopt the trade credit strategy; meanwhile, they employ a certain technology to reduce the deterioration rate of the products. Therefore,in this paper, the affection of the preservation technology investment is considered to the deterioration rate of the perishable goods, to discuss the purchaser's optimal ordering strategy and technology investment strategies in the trade credit payment mode. First of all, according to the trade credit period and the ordering cycle, the relationship between the purchaser's interest income and the interest payments are divided into the two cases.Secondly, by theoretical derivation, the optimal order strategies can be obtained and give out the optimal preservation technology investment strategy is given out. Finally, the theorem and the conclusions of this paper are verified by the numerical analysis, and also make sensitivity analysis of parameters. It is found that, when the preservation technology investment has a strong influence on the deteriorating rate, the purchaser preservation technology investment is low and the optimal order cycle is prolonged; when the natural deteriorating rate of the product increases, the purchaser increases the investment amount of preservation technology in order to reduce the deterioration rate, and its profit decreases; when the credit period given by supplier to procurement business increases, the firm's optimal preservation technology investment amount and order cycle decrease and its profit increases.
