| Abstract: | A single factor pot experiment was conducted to investigate effect of zinc to the growth of cornand nutrient uptake in the fourth red clay soil.The results showed that zinc obviously promoted to the growth of corn in the density 0.5~200 mg/kg the soil scope,it had advantages to nitrogon absorption of corn.The highest absorption intensity of zinc appeared from jointing stage to tasseling stage,the zinc contains amount of corn descend trend along with it's growth. |
