Taking lettuce and its soil nutrition as a system, with the controlled factors including N, P, K as input, and with the yield of lettuce as output, a yield predic tion model was built. Thus, the proper combination of applied N, P and K for higher yields of lettuce could be obtained from the model, and the N∶P∶K ratio for yields above 100g/plant was estimated to be 1∶0.5∶1.1.
本试验条件下，要获得100克／株以上的产量，氮磷钾配比应为1∶0．5∶1．1。
