| 摘 要： | 采取田间试验与室内分析相结合的方式,研究了施硅对露地栽培草莓的光合特性和产量的影响.结果表明:施硅可提高草莓叶片净光合速率(Pn)、气孔导度(Gs)与胞间CO2(Ci)浓度,降低蒸腾速率(Tr),提高草莓植株对水分的利用;施硅可提高草莓单株结果数、平均单果重,降低畸形果数和病果数,进而明显地提高草莓产量,不同施硅处理和对照相比,增产幅度达到10.28%～29.24%,当施硅量为2.93 kg/667m2时,可获得最高产量.

| Abstract: | In this study,field experiment and lab analysis were combined to study the effect of silicon application on photosynthetic characteristics,yield of open cultivated strawberry.These studies had provided results to suggest that silicon supplied to strawberry can increase leaf net photosynthetic rate(Pn),stomata conductance(Gs)and intercellular CO2(Ci);and also decreased transpiration rate(Tr),promoted the water use efficiency of strawberry.By silicon offered to strawberry,it can advance the fruit number indiv... |
