摘  要:
An optimized regression design with three factors and five levels was applied to study the effects of N, P and K fertilizers on the yield of Chinese Cabbage and its nitrate content in Guiyang. The optimum combination of the three fertilizers was shown to be in the range of N 180~200kg/hm 2+P 2O 5120~150kg/hm 2+K 2O120~150 kg/hm 2 , which gave high yields of the crop with low contents of nitrate.
