鹽脅迫是限制農(nóng)業(yè)生產(chǎn)的主要因素之一,也是影響全世界作物產(chǎn)量的最重要的環(huán)境因子。相反,當(dāng)今的作物產(chǎn)量并不能滿足人們的需求。為了確保鹽分影響區(qū)域的農(nóng)業(yè)可持續(xù)發(fā)展以及作物產(chǎn)量不斷提高,克服水分虧缺以及鹽脅迫是最為重要的問題。因此,本論文選取諸葛菜和油菜為材料,通過研究其光合作用,水分利用效率,水勢,碳酸酐酶活性,生理電容和葉片緊張度來對比分析其耐鹽能力。結(jié)論如下:1)研究諸葛菜和油菜的鹽誘導(dǎo)效應(yīng)和后期再復(fù)水的生理特性;2)基于鹽脅迫和再復(fù)水的生長和生理響應(yīng)探索最優(yōu)的復(fù)水機制;3)基于諸葛菜和油菜的電生理特性建立一種預(yù)測稀釋鹽水機制的模型。在溫室內(nèi)種植油菜和諸葛菜。用NaCl、Na2SO4和兩者的混合來對油菜和諸葛菜分別進(jìn)行處理;把NaCl 和 Na2SO4 的濃度分別設(shè)置為（NC1: 2.5, NC2: 5, NC3: 10） g L-1 （NS1: 2.5, NS2: 5, NS3:10）g L-1 以及將不同濃度的兩種鹽進(jìn)行混合得到混合鹽溶液（MS1: 2.5 NaCl + 10 Na2SO4;MS2: 10 NaCl + 2.5 Na2SO4; MS3: 5 NaCl + 5 Na2S...
