Rhizosphere aeration. irrigation.with aerated water, an. post-irrigation.aeration.would positively impact crop growth an. yield. The objective of this study was to determin. the effect of 4 post-irrigation.aeration.levels on.plan. growth, yield, irrigation.use efficien.y （IUE）, an. fruit market an. n.trition.l quality of green.ouse cucumber un.er subsurface drip irrigation.（SDI） an. furrow irrigation.（FI）. The post-irrigation.aeration.levels were 0.00, 0.50, 0.75, an. 1.00 times half the estimated porosity of the plot rhizosphere. The experimen.al design.was a two-faetor split-plot in.ran.omized complete blocks with irrigation.（FI an. SDI） as the main.treatmen.s an. 4 aeration.levels as the sub-treatmen.s. Ridge an. furrow main.plots （2.4 m ~ 2.4 m） with 4 ridges were replicated 5 times. Each of the 4 ridges （1.44 m2 in.area） in.the main.plots was used as a sub-treatmen. plot. The results showed that post-irrigation.aeration.en.an.ed green.ouse cucumber plan. growth, yield, IUE, an. fruit market an. n.trition.l quality. These parameters gen.rally in.reased with in.reasin. aeration.levels un.er both FI an. SDI. The aeration.effect was gen.rally higher un.er SDI than.FI, an. the IUE un.er SDI was almost twice that un.er FI. Further in.estigation.would be required to elucidate the plan. physiological mechan.sms an. soil processes respon.ible for the observed effects.
