According to reports,Recently, farmers in Kaifeng, Henan Province used the principles of the Shanghai Tower damper to protect their vegetable greenhouses with homemade sandbag dampers. This innovative move has attracted widespread attention.According to statistics from the China Meteorological Administration, agricultural losses caused by wind disasters in my country amount to billions of yuan every year. Recently, Henan has been affected by strong cold air. Strong winds have occurred in most areas of the province, with local gusts reaching level 10 or above. Farmers are in urgent need of effective wind protection measures.
The production of sandbag dampers seems simple, but actually contains scientific principles. Farmers find woven bags, fill them with soil, and hang them at key locations in the greenhouse or around the farmland at intervals of one meter.When strong winds sweep across the greenhouse, the sandbags begin to swing and generate a reverse force, thereby effectively reducing the impact of wind on the greenhouse.
This kind of homemade damper is not only low in cost, the materials are just bags and soil, and almost every household can afford it; it is also easy to make, does not require complicated technology, can be used by everyone, and can be easily promoted.
There are many examples like this of folk wisdom solving difficult problems. In Yunnan, in order to prevent the terraces from being washed away by rain, local farmers invented a unique "field ridge reinforcement method", which uses stones and soil to build strong ridges, effectively protecting the terraces. Also in Sichuan, in order to cope with frequent heavy rains in summer, farmers dug drainage ditches around orchards, cleverly solving the problem of water accumulation in orchards. These innovative measures not only demonstrate the wisdom of farmers, but also provide valuable experience for the sustainable development of agricultural production.
