| 为探求纳米水溶性铜锌复合制剂对猕猴桃溃疡病的防治效果及对植株生长发育的影响,以可杀得三千为药剂对照,以清水为空白对照,研究不同预防处理方式和治疗处理的防治效果。结果表明：冬、春两季(T3处理)喷涂预防效果可达86.90%,其效果优于冬季(T1处理)的80.63%和春季(T2处理)的72.95%；治疗处理(T4)的治愈率为70.93%,有效率高达92.16%,显著高于药剂对照和空白对照。同时,喷施纳米水溶性铜锌复合制剂可显著改善猕猴桃染病植株的光合作用、提升果实产量和果品质量,且果品重金属和农残均未超标。这为猕猴桃溃疡病的大田防控提供可能的借鉴。 |
| 英文摘要: |
| In order to explore the preventive and therapeutic effects of Nano Water-Soluble Copper-Zinc composite preparations on kiwifruit ulcer disease and its impact on plant growth and development, Keshade 3000 was used as the drug control, and clear water was used as the blank control to study the preventive and therapeutic effects of different prevention and treatment methods. The results show that the preventive effect of spraying both in winter and spring (T3 treatment) could reach 86.90%, which was better than 80.63% in winter (T1 treatment) and 72.95% in spring (T2 treatment). The cure rate of treatment (T4) was 70.93%, and the effective rate was as high as 92.16%, significantly higher than the drug control and blank control. Beside, spraying nano water-soluble Copper-Zinc composite formulation can significantly improve the photosynthesis of kiwifruit infected plants, increase fruit yield and quality, and the heavy metals and pesticide residues in the fruit are not exceeding the standard. This provides possible reference for the field prevention and control of kiwifruit ulcer disease. |
