Some blueberry varieties are more tolerant of high-pH soil, such as ‘Chaoyue No.1’ and ‘Briteblue’. These two varieties perform quite well in slightly alkaline soil. To maintain an appropriate soil pH, materials such as sulfur, peat, pine needles, and acidified rice husks can be used to adjust the acidity. Before planting, measure the pH value first. If it is too high, apply sulfur powder or sulfur-containing compound fertilizer. If it is too low, add some lime to adjust it. The combined use of organic substances can not only regulate the pH level but also improve soil structure and increase organic matter. When planting, it is recommended to give priority to using ammonia nitrogen fertilizer and combine it with bacterial fertilizer to optimize the rhizosphere environment. In some slightly alkaline areas, the method of “flat furrows + pine sawdust + sulfur acidification” can be adopted to grow blueberries, which is cost-effective and highly effective. Although these methods have a certain application foundation, the specific response mechanism of blueberries under high pH stress still requires in-depth research. In the future, AI technology can be integrated to monitor soil pH and crop conditions in real time through sensors, achieving precise regulation. Meanwhile, the introduction of beneficial microorganisms, the promotion of organic alternative chemical fertilizers, and the development of intercropping models are also expected to achieve green planting while ensuring yield, and promote the sustained and healthy development of the blueberry industry.
