[0002] The phenomenon of soil acidification in my country is becoming more and more serious. The application of quicklime can not only reduce the acidity of the soil, but also passivate the heavy metal elements in the soil and enhance the activity of microorganisms in the soil, thereby promoting the decomposition of organic matter and the fixation of nitrogen. The traditional way of spreading quicklime is manual spreading, and the quicklime needs to be carried by humans, which is labor-intensive and inefficient. Quicklime is highly corrosive and can easily corrode the skin and cause harm to the human body during the spreading process. Manual spreading is uneven and causes large dust, which can easily cause environmental pollution. Therefore, studying the powdered lime spreading technology and equipment to solve a series of problems caused by soil acidification is of great significance to ensuring the sustainable development of agriculture.
