Taitai (Reporter Yang Yujie) Yesterday, the Provincial Quality Supervision Bureau announced the sampling results. There were 14 enterprises in Tai 'an, among which one cable battery enterprise was unqualified, the unqualified item was reserve capacity, one compound fertilizer enterprise was unqualified, and the unqualified item was potassium oxide.
This year, Shandong Provincial Bureau of Quality and Technical Supervision organized a joint quality supervision and spot check of lead-acid battery products, power cable products and compound fertilizer products. It is understood that 20 batches of lead-acid battery products, 50 batches of power cable products and 120 batches of compound fertilizer products produced by 120 enterprises were randomly selected in this province. Among the 14 enterprises involved in Taian, there are 3 power cable products enterprises, 8 compound fertilizer products enterprises and 3 lead storage battery enterprises. The lead-acid batteries sampled in the province found that two batches of products from two enterprises did not meet the requirements of relevant standards. The unqualified items involved reserve capacity, low-temperature capacity and high-rate discharge, and the unqualified rate was 10%. Lead-acid batteries produced by Taian Shihua Cable Battery Co., Ltd. are "famous on the list" 因为他们没有足够的储备能力。电力电缆产品抽查中，发现6家企业的6批次产品不符合相关标准要求。不合格项目涉及PVC护套失重和非金属护套最薄处厚度，泰安市抽检的3家企业产品全部合格。
复合肥产品抽查发现，11家企业的11批次产品不符合相关标准规定。不合格项目涉及总氮、氧化钾、总养分、氯离子和包装标签。泰安企业山东鲁玉娥化工有限公司生产的复混肥中氧化钾不合格。
据了解，钾是植物生理活动中最重要的元素之一，可以调节植物水分、阴离子和阳离子的平衡，参与光合作用。作物缺钾会影响根系生长，导致作物容易倒伏，叶片出现坏死斑。化肥产品是农业生产的主要生产资料之一。不合格的产品，尤其是营养指标不合格，将直接影响农作物的生长，导致最终产量的降低。
