Abstract：In this experiment, pot experiments were conducted to investigate the growth conditions of Oenothera glazioviana, the copper contamination soil and sand respectively according to the 1:0、1:1、1:2、1:3、2:1 and 3:1 mixed to breed Oenothera glazioviana, to understand the barren tolerance of Oenothera glazioviana, using the "3414" two regression D- optimal design, the incomplete orthogonal regression design was applied to the amount of N, P and K fertilizer, the effect of nitrogen, phosphorus and potassium fertilizer on the growth of Oenothera glazioviana was analyzed by the regression equation of fertilizer effect, aim to screen out fertilizer formulas. The results showed that the Oenothera glazioviana had higher barren tolerance, the proportion of sand soil mixed matrix accounted for 50%-100%, Sand mixing ratio matrix is greater than 50%, the fertility level can not meet the normal growth of plant; The soil fertility ratio is 50%,The content of organic matter-16 g kg-1、Nitrogen content-48 mg kg-1、The content of available phosphorus-5 mg kg-1、The content of available potassium-80 mg kg-1,according to the soil nutrient classification formulation of the second national soil survey in the low level of soil nutrients to 4-5 level.the fertility level can meet the long-term demand growth of yellow primrose. The optimum proportion of nitrogen, phosphorus and potassium fertilizer was N:P:K=2.43:1:1.09 in the planting environment of Oenothera glazioviana seedlings, and the optimum amount of nitrogen, phosphorus and potassium were 372.69 mg kg-1, 153.68 mg kg-1 and 167.65 mg kg-1 respectively.
