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。 -

This paper deals with the existence of two positive solutions for critical elliptic equations with a changed sign perturbation and with an auxiliary condition. first of all, the super - sub - solution can be obtained by this positive solution and by the auxiliary condition if perturbation is the positive side of the changed sign perturbation, and then the equation has a positive solution by the method of monotone in teraction and by the maximum principle. because that the positive solution of the equation isnt monotone to parameter. although all of the equations have a positive solution to two given parameters, the existence of the positive solutions of its equation to a parameter between the two given parameters cant be proved. finally, if the first positive solution exits the second solution for the equation can be proved by the mountain pass lemma. 7refs
討論了帶變號擾動並且具有一定附加條件的臨界橢圓方程的兩個正解存在性.首先由變號擾動的正部對應的方程的正解和附加條件構造出原方程的一個上、下解，再由迭代方法和極值原理得到方程的第一個正解.考慮到方程的正解對參數沒有單調性，因此，即使對于兩個使得方程都有正解的參數，但在這兩個參數之間的參數對應的方程不一定有正解.最後，如果方程存在第一個正解，那麼由山路引理可得到方程的另一個正解.參7 -
