摘要
Abstract
In this study, the tests of formulated fertilization for potato in main producing areas of Shandan were conducted by application of the method of “3414” complete design test. The regression equation between potato yield and application amounts of N, P, K was established, and the maximal application amounts of N, P, K were obtained. The amounts of N, P, K were N 242.99 kg/hm2, P2O5 159.27 kg/hm2, K2O 159.03 kg/hm2 , respectively. Under the fertilizer level, potato yield was 48 934.00 kg/hm2. Additionally, the optimal application amounts of N, P, K were also found. The optimal application amounts of N, P, K were N 224.61 kg/hm2, P2O5 149.06 kg/hm2, K2O 146.8 kg/hm2, respectively . Under this fertilizer level, potato yield was 48816.00 kg/hm2 and the ratio of N, P2O5, K2O should be 1:0.66:0.65.关键词
