土壤水肥交互作用与玉米的响应

Corn responds to interaction between soil moisture and fertilizer

  • 摘要: 对豫北地区玉米水肥交互作用试验进行分析,结果表明,玉米生长最快时期为拔节~抽穗期。养分与玉米的高度及生物量间有较为复杂水肥协同效应,影响了玉米生物量的构成。玉米产量、耗水量同水肥供应量之间存在非线性二次关系,由玉米产量同耗水量的二次关系获得最高产量、最高水分利用效率条件下的玉米耗水量。

     

    Abstract: The corn experiments of different soil moistures and nutrients in the north of Henan Province showed the fast growth period of corn is between shooting period and heading period, and the interaction between corn height or biomass and soil nutrient is complicated. The constitution of corn biomass is a ffected by soil moisture and nutrient. Relation between corn yield or water consumption of corn and water and fertilizer supply is quadratic curve. From the relation, the water consumption under the highest yield and most efficient water use conditions was got.
