不同浓度可杀得叁千对西瓜幼苗叶片光合系统的影响

Effects of Different Concentrations of KCD3000 on Photosynthetic System of Watermelon Seedling Leaves

为了研究铜制剂对西瓜幼苗光合系统指标的影响,为西瓜病害的防控提供有效药剂及适宜的施用浓度,以西瓜幼苗为试材,研究了不同浓度可杀得叁千叶面喷施对西瓜幼苗叶片光合系统指标的影响。结果表明:随着铜浓度的提高,西瓜幼苗叶片内光合系统指标以可杀得叁千浓度4.7 mmol/L和9.4 mmol/L为分界线先上升后下降。

In order to study the effect of copper preparation on the photosynthetic system index of watermelon seedlings,at the same time,to provide effective pesticides and suitable application concentration for the prevention and control of watermelon diseases,the watermelon seedlings were used as test materials,and the different concentrations of KCD3000 were sprayed on the leaves of watermelon seedlings.The impact of photosynthetic system indicators.The results showed that with the increase of copper concentration,the photosynthetic system index of watermelon seedling leaves increased first and then decreased with KCD3000 concentration of 4.7 mmol/L and 9.4 mmol/L.
