土壤研究区的土壤为针叶松柏，表面坚硬，白色，盐分和pH高，土壤结构差，

The soil in the soil <br>study area is coniferous cypress, with hard surface, white color, high salinity and pH, poor soil structure and low fertility. The exchangeable sodium saturation percentage (ESP) of takyric solonetz is as high as 42.1%, and the pH may be as high as 9.0–10.5 (Table 1). The sediment is the material of takyric solonetz. There are three layers along the soil profile: natural layer, transition layer and matrix. The natural layer consists of a 1 cm thick hard shell layer with pores and a 40 cm thick hard corner block structure. The transition layer also has a block structure. The parent layer of lake sediments has a low degree of alkalization. Clay minerals (mainly hydromica, but also chlorite, kaolinite and montmorillonite) appear in nature, but the content of calcium sulfate is too low to improve the soil.

Soil.<br>The soil in the study area is conifer cypress, the surface is hard, white, salt and pH is high, the soil structure is poor, and the fertility is low. The percentage of exchangeable sodium saturation (ESP) of takyric solonetz is as high as 42.1%, and the pH can be as high as 9.0-10.5 (Table 1). Sediments are materials of tatyric solonetz. There are three layers along the soil profile: the natural layer, the transition layer and the parent. The natural layer consists of a 1 cm thick hard shell layer with fine holes and a 40 cm thick hard corner block structure. The transition layer also has a block structure. The alma mater layer of lake sediments is low in alkalinity. Clay minerals (mainly jellyfish, as well as turquoise, kaolin and montessite) are found in nature, but calcium sulfate levels are too low to improve the soil.

soil<br>The soil in the study area is coniferous pine and cypress with hard surface, white color, high salinity and pH, poor soil structure and low fertility. The percentage of exchangeable sodium saturation (ESP) of takyric solonetz is as high as 42.1%, and the pH value may be as high as 9.0 – 10.5 (Table 1). The sediment is the material of takyric solonetz. The soil profile is divided into three layers: natural layer, transition layer and parent layer. The natural layer consists of a 1 cm thick hard shell with pores and a 40 cm thick hard horned block structure. The transition layer also has massive structure. The alkalization degree of the parent material layer of lake sediments is low. Clay minerals (mainly hydromica, chlorite, kaolinite and montmorillonite) occur in nature, but the content of calcium sulfate is too low to improve the soil.<br>
