The study of soil nutrient fastness tester studied the soil nutrient characteristics in the rhizosphere and woodland soils of mixed forests of Schima superba and Cunninghamia lanceolata, in order to provide scientific basis for exploring the benefit mechanism of Schima superba and Cunninghamia lanceolata mixed forest. Woodland soil (all soil); in each plot, evenly selected 5 normal growing trees, and used the exfoliation method to collect proper amount of soil adhered to fine roots with a diameter of less than 2 mm in a 0-40 cm soil layer, and discarded the root exfoliation material. After mixing well as a rhizosphere soil sample. After drying, the soil sample over 0.25mm sieve was used for the soil nutrient fastness tester to determine the total amount of nutrient content and organic matter content, and the soil sample over 2mm sieve was used to determine the available nutrient content.
The nutrient content of forest soil is a complex variable in the natural environment. The growth of forest stand has a close relationship with the dynamic change of soil nutrient. From the values ​​of the soil nutrient quickness tester, it can be seen that the organic matter, total nitrogen, and total phosphorus content in forest soil (0-40cm) are highest in Schima superba, and there is no significant difference in total potassium content among the three stands. It is mainly related to the composition of litter and the biological characteristics of the tree species in different stands. The highest available nutrient content was mixed forest, indicating that the three elements N, P, and K in forest soil were activated and accumulated in the mixed forest.
The average height and mean diameter at breast height of Chinese fir and Chinese fir forests in mixed forests were significantly different, which increased by 22% and 18% respectively. The volume of mixed forests also increased by 29% and 29.4 compared with that of Schima superba and pure Chinese fir forests, respectively. %a. It can be seen that the establishment of a mixed forest of lotus and fir can promote the growth of Schima superba and Cunninghamia lanceolata. The measurement and analysis of the soil nutrient fastness tester showed that the mixed forest has the effect of improving the soil fertility, thus increasing the forest productivity.

Analysis of Effects of Soil Nutrient Analyzer on Fertility in Mixed Forest
The way of improving soil fertility is relatively insignificant, but there are certain shortcomings in the simple way of using chemical fertilizers to increase. Among them, mixing is also an important method to increase forest productivity and improve fertility. However, increasing fertility and nutrients are related to many factors, but also need to be analyzed based on actual changes in nutrient dynamics. Nutrients mainly come from the roots, so whether it is roots or nutrients through the soil nutrient fastness tester has important practical significance.
