旱地作物生育对土壤水肥耦联的响应研究进展

The response of the dryland crop development and growth to the coupling of the soil water and fertilizers

  • 摘要: 水肥是作物生长发育的基本物质基础,也是制约农业的主要因素。90年代以来我国在水肥对旱作 农业生产的协同效应方面做了大量的定性或定量研究工作,较为系统、深入地分析了旱地作物生长发育及产量对农田土壤水肥的响应。在总结分析的基础上指出水肥对旱地作物作用大小是随水肥相对平衡而变化。

     

    Abstract: The soil water and the fertilizers are the basic materials of the crop development and growth and also the main physical elements which limit the world agriculture.A great number of researches on the response of the dryland crop to the coupling of the soil water and fertilizer has been worked out since 1990' in the northern drought region of China.On the base of those researches,the present paper shows that the extent of the effect of soil water and fertilizers on the dryland crop changes with the relative balance between the soil water and fertilizers' quantity.
