【摘要】 为研究施氯对烟草植株光合特性的影响,采用盆栽试验研究了不同施氯量对K326烟草植株光合作用及最大叶各指标的影响。结果表明,随施氯量增加,光合作用增强,到达一定量后,效果下降。每公顷施用45kgNH4Cl效果最好。更多还原

【Abstract】 Pot experiments were conducted to study the effects of different chloride treatment on photosynthetic characteristics as well as the indexes of the biggest leave of tobacco plants K326. The results show that plant photosynthesis increases with the chloride application dosage but the efficiency will decrease after the application dosage reaches to a certain amount. Application of 45kg ammonium chloride (NH4Cl) per hectare is found to be the best treatment.更多还原
