In agricultural production, we will find such an interesting phenomenon, that is, the same crops produced well on this land for the first time. After replanting, although the management methods used are the same, the effect is obviously reduced. This phenomenon is also known as the obstacle to the replantation of crops. Soil is the basis for the growth of crops. Crops are subject to replantation and are greatly affected by the soil. Therefore, soil tests such as soil acidity meters are used to test the soil. Concerning soil quality, it is an effective measure to prevent crop replantation obstacles. one.
The heavy use of pesticides or fertilizers, while playing a role in agricultural production security, production increase, etc., but it has caused a huge burden on the soil due to unreasonable application, such as poor soil, high or low pH, and nutrition. Disproportional proportion of elements, poor soil properties, etc. If these problems are not solved, the crops will grow in the soil and there will be no way to meet the growth requirements, which will cause growth problems and lead to a reduction in production. Therefore, to prevent the replantation of crops, we need to start from the most basic soil. In recent years, the application of instruments such as soil acidity meters has provided technical support for solving soil health problems.
Soil pH meter is mainly used to determine the pH value of the soil. Soil pH is an important environmental factor that affects plant growth. Different crops have different pH environments during different growth periods. Therefore, in the production process, Using the soil acidity meter to pay close attention to soil pH changes, and effectively regulate and improve the soil pH value based on the test results, can fundamentally solve the important impact factors of crop replantation obstacles - soil problems, promote crop nutrient absorption and photosynthesis , To achieve harvest yields of agricultural planting effectiveness.
