  1. The result of experimentation on coupling effect of water and fertilizers on spring corn in the three gorges reservoir area indicate that water stresslead the effect low of highness and lai, and the most effect is made in shooting stage ; it has a significant positive correlation between the yield of corn and biomass, and hasn ' t none significant positive correlation between the yield of corn and the weight of roots ; the coupling effect of water and n is significant, but the coupling effect of water and k is not significant, the maximum yield of corn condition fitting - water and medium n, corn absorbs n has a threshold value during the growth, and using superfluous n is able to prick up soil drought and crop drought ; water is the leading factor which effects the yield of corn, next is n and k

    摘要三峽庫區春玉米盆栽水肥耦合試驗研究結果表明，水分脅迫導致玉米株高和葉面積指數降低，以拔節期受到影響最大；玉米產量與生物量呈顯著正相關關系，產量與根重無顯著正相關關系；水氮耦合效應顯著，適宜水分和中氮處理下玉米的產量最高，玉米生長發育對氮肥的吸收存在一定的閾值，過多施用氮肥會加劇土壤乾旱和作物乾旱，水和鉀耦合效應對玉米產量影響不顯著；水分是影響玉米產量的主導因素，其次是氮效應和鉀效應。
