In general, the pH of a normal neutral soil is approximately 7 or so. However, in recent years, many orchards have used the soil acidity meter to determine that the soil became more acidic and the soil pH was already seriously below 7. The acidified soil is unfavorable for the growth of most fruit trees. Therefore, to achieve a healthy orchard cultivation, it is necessary to take measures to improve the orchard soil acidification and avoid the acidification of the orchard soil. The application of soil acidity meter can provide important guidance for the regulation of pH in orchard soil, and provide a healthy soil environment for the healthy planting and development of orchards. Acidification of orchard soils is prone to a series of adverse effects. For example, if more fertilizers are used, the fruit size is small, the yield is low; dead trees, dead shoots, rotten roots, dead roots, resistance to disease decline, etc., and soil acidification. It will also aggravate the occurrence of manganese poisoning, aggravate the occurrence of physical diseases such as bitter pit disease and rough skin disease. Therefore, if the orchards want to increase production and income, the soil health protection work must not be relaxed. In terms of science, the most suitable PH value for fruit tree growth is 6-7.5. In the daily management work, we must use the soil acidity meter to test the soil. It can be used to prevent severe acidification of the soil. Second, it can also According to the specific values ​​determined, the acidic soil is conditioned to maintain the health of the orchard soil. The more acidic the soil is, the more related to the daily fertilization management of orchards, and the abuse or unreasonable use of chemical fertilizers is one of the most important causes of soil acidification. Therefore, to completely solve the problem of soil acidification, it should be started from the regulation of orchard fertilization. In the orchard's daily management work, using the soil acidity meter to measure the acidity or alkalinity of the orchard soil, not only can early find the signs of soil acidification, take early measures to regulate and control, but also can use chemical fertilizers for orchards to increase the utilization of chemical fertilizers. To a certain degree of promotion. From this, it can be seen that the application of instruments such as soil acidity meter is an important guarantee for the modern orchard to carry out healthy planting and increase production and quality.
