| 为弄清离子果膜对沃柑果实日灼、品质和光合的影响,2018-2019年在广西武鸣进行了喷施不同浓度离子果膜对沃柑果实日灼发生率、果面温度、叶片光合速率和果实品质的影响试验。结果表明,喷了离子果膜的沃柑果实日灼发生率为0.98%-1.73%,极显著低于对照的14.77%；沃柑叶片Pn日变化呈双峰曲线,存在“午休”现象,同一时刻不同处理间沃柑叶片净光合速率存在一定的差异,但与对照间的差异未达显著水平。在气温33.1℃情况下,喷了离子果膜的沃柑果面平均温度39.97℃-41.47℃,而对照果面平均温度达到48.36℃,两者相差6-8度,其差异达到极显著水平。离子果膜对果实着色、果皮厚度、果实可溶性固形物、固酸比的影响不显著,但对糖代谢影响显著,不同处理间差异明显。对照的果实可滴定酸含量均显著低于4个处理,4个处理间的差异不显著。离子果膜预防沃柑果实日灼效果显著。 |

| The purpose of this study is to provide a reference for the selection of sunburn agents for citrus fruits in production.SThe effects of ionic fruit film on sunburn and leaf photosynthesis of citrus fruits were investigated, tested and statistically analyzed.SThe results showed that the sunburn rate of citrus fruit sprayed with ion film was 0.98%-1.73%, which was significantly lower than that of the control (14.77%).SThe diurnal variation of PN in mandarin leaves showed a bimodal curve, and there was a phenomenon of "lunch break". There were some differences in the net photosynthetic rate of mandarin leaves between different treatments at the same time, but the difference between the two treatments did not |
