When the PH value is greater than 5.5, it is necessary to use sulfur powder or aluminum sulfate to reduce the PH value. The application of sulfur powder should be carried out one year before planting or at least in the year of planting, but it usually does not work in the year after the application of sulfur powder, such as dark brown forest soil, a pH value of 15 cm per square meter to reduce a PH value need to apply sulfur powder 130 grams, the effect can be maintained for more than 3 years, other types of soil can refer to this amount. Sulfur powder was evenly thrown into the whole garden soil according to the calculated application amount, and deep-turned 15 cm to mix. If aluminum sulfate is used, the amount is 6 times that of sulfur powder. In addition, the soil was mixed with acid peat, and the application of acidic fertilizers to cover sawdust and rotten bark had the effect of lowering the pH. If sulphur powder is used in combination with peat, the effect is better. The adjustment of the soil PH value is too low When the soil PH value is lower than 4, due to excessive heavy metal elements caused poisoning, so that blueberry growth is poor or even death. At this point need to increase the PH value, commonly used lime to adjust. When the soil pH is 3.3, the application of 8 tons of lime per hectare can increase the PH value to more than 4 and the yield increase by 20%.
