Abstract：The absorption and distribution characteristics of nitrogen, phosphorus and potassium on‘Tinglin Xuegua’were studied under the condition of spring greenhouse. The results showed that the distribution of N, P, K was mainly used for the development of leaf before fruit-set, and then used for the growth of stem, turns to fruit development gradually after fruit set?ting. The absorption of K was slightly higher than N, the least was P of the plants. The total amount of N, P, K absorbed by‘Tinglin Xuegua’in fruit setting stage was 6.12 g per plant, and the ratio of N:P2O5:K2O was 1∶0.15∶0.84;the total amount of N, P, K absorbed in fruit mature stage was 23.53 g per plant, and the ratio of N∶P2O5∶K2O was 1∶0.21∶1.32. Therefore, it is not suitable to apply single fertilizer which the ratio of N∶P2O5∶K2O was 1∶1∶1 in agricultural production.
