After soil acidification, the nutrient uptake rate of fruit trees decreases, the fruit growth is small, the total yield of the orchard is low, the fruit is different, and the orchard cannot be sold, which directly affects the economic income of the orchard. Outwardly, most people mistakenly think that this is a lack of fertilizer, and consciously increase the use of chemical fertilizers, which exacerbates soil acidification in a vicious circle. The soil nutrient detector can accurately detect the nutrients in the orchard soil, the instrument can accurately measure the nutrient content of the soil layer, accurately control the nutrient content of the soil layer, and assist fruit farmers to detect soil formula fertilization, which can not only improve the yield and quality of crops, but also reasonably avoid environmental pollution caused by excessive fertilization.
Therefore, it is necessary to test the orchard soil with a soil nutrient detector, which can detect nitrogen, phosphorus and potassium, total nitrogen, total phosphorus, total potassium and soil organic matter pH value in soil and fertilizer, organic fertilizer, plants, salt, calcium, magnesium, manganese, boron, zinc and other nutrients and various heavy metals such as lead, chromium, cadmium, mercury and arsenic exceed the standard.
The soil nutrient detector can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon and other medium and trace elements in the soil and chemical fertilizers, organic fertilizers and plants, as well as various heavy metals such as lead, chromium, cadmium, mercury and arsenic. It can scientifically calculate the recommended fertilizer application amount for the target yield of more than 100 kinds of agriculture, fruit trees and cash crops.
