| 以普通农药为对照、自来水为空白对照,研究不同剂量铜基纳米农药对葡萄植株光合作用和果实品质的影响。结果表明,喷施普通农药抑制了葡萄植株的生长发育,叶绿素合成、光合作用和光合电子传递均受到抑制；与普通农药相比,喷施不同剂量的铜基纳米农药后,葡萄植株的叶绿素含量、Pn、Gs、Ci、Tr均显著提升,光合电子传递速率加快；与空白对照组相比,中低剂量铜基纳米农药处理下,葡萄植株的叶绿素含量、光合参数(Pn、Gs、Ci、Tr)和大部分叶绿素荧光参数均显著升高,但高剂量则产生抑制作用。同时,中低剂量铜基纳米农药可提高葡萄果实的品质,但高剂量和普通农药处理则使得果实品质受到影响。这为铜基纳米农药应用于葡萄白腐病等病害防控提供可能的理论支撑。 |

| Using ordinary pesticides as control and tap water as blank control, the effects of different doses of Copper based Nanopesticides on grape plant photosynthesis and fruit quality were studied. The results showed that spraying ordinary pesticides inhibited the growth and development of grape plants, by chlorophyll synthesis, photosynthesis, and photosynthetic electron transfer inhibited. Compared with ordinary pesticides, spraying different doses of Copper based Nanopesticides, the Chlorophyll content, Pn, Gs, Ci, and Tr of grape were significantly increased, and the photosynthetic electron transfer rate was accelerated. Compared with the blank control group, the chlorophyll content, photosynthetic parameters (Pn, Gs, Ci, Tr), and most chlorophyll fluorescence parameters of grape were significantly increased that were treated by medium and low doses of Copper based Nanopesticides, when high doses produced inhibitory effects. Besides, low to medium doses of Copper based Nanopesticides improved the quality of grape fruits, when high-dose and conventional pesticide treatments made fruit quality reduced. This provides possible theoretical support for the application of Copper based Nanopesticides in the prevention and control of grape Coniothyrium diplodiella (Speg.) Sace. and other diseases. |
