随着春季的到来，花粉飞絮成为许多城市居民“会呼吸的痛”。为解决这一环境问题，多地绿化部门开始尝试创新防治策略，包括为树木进行“变性手术”以及用有机物覆盖地表等新颖方法。
据了解，这种“变性手术”主要针对产生大量飞絮的雌性杨树和柳树。通过人工授粉，将雄性植株的花粉引入雌性植株，使雌树结出无絮种子，从而减少花粉飞絮的产生。这一技术不仅有效控制了飞絮，同时也保护了树木种群的多样性。
另一方面，用有机物覆盖地表的措施也在多地推广。通过覆盖落叶、稻草等有机物质，可以抑制地表杂草生长，减少花粉源，同时还能改善土壤结构，增强土壤保水保肥能力。这种方法既环保又经济，得到了绿化专家的肯定。
防治花粉飞絮的战役已经从传统的清扫、喷洒药剂转向了更为科学、环保的策略。这些创新举措不仅减轻了市民的过敏困扰，也展示了城市绿化与生态环境保护的和谐共生。未来，我们期待更多这样的绿色解决方案，让城市呼吸更畅通，让生活更美好。

Title: Tackling Pollen Fluff, Urban Greening Embraces “Innovative Approach” – Tree “Sex Change” Operations and Organic Ground Cover Trials
As spring arrives, pollen fluff becomes a literal “breathing pain” for many city dwellers. To address this environmental issue, various urban greening departments are experimenting with innovative control strategies, including performing “sex change” operations on trees and using organic materials to cover the ground.
It is understood that these “sex change” surgeries mainly target female poplar and willow trees that produce abundant fluff. By artificially pollinating female plants with pollen from male trees, the雌树 produce seedless fruits, thereby reducing pollen fluff production. This technique effectively controls fluff while preserving the diversity of the tree population.
On the other hand, the practice of covering the ground with organic substances is also gaining traction. By using leaves, straw, and other organic materials, weed growth is suppressed, minimizing pollen sources. Additionally, it improves soil structure and enhances the soil’s water and nutrient retention capacity. This eco-friendly and cost-effective method has received praise from green experts.
The battle against pollen fluff has shifted from traditional sweeping and chemical spraying to more scientific and environmentally friendly tactics. These innovative measures not only alleviate citizens’ allergy woes but also exemplify the harmonious coexistence of urban greening and ecological preservation. Looking ahead, we anticipate more such green solutions to facilitate smoother city breathing and enhance the quality of life.
