摘要: Silicon can promote rice growth and reduce the toxicity of heavy metals in rice. However, controlling factors for the vertical distribution of silicon in typical paddy soils in mid-subtropical regions of China remain largely unexplored. Here, we aimed to analyze the silicon content in plough and subsurface layers derived from six parent materials in Hunan Province (southern China) based on 62 soil profile samples. Multiple stepwise regression, random forest, and gradient boosting machine learning models were used and compared to predict soil available silicon content and quantify the contribution of different variables on silicon variation. We found that plough layers in the eastern (85% of points) and western (78% of points) Hunan Province were deficient (< 100 mg kg(-1)) in available silicon content. Total silicon content in paddy soil derived from slate (623 & PLUSMN; 100 g kg(-1)) and limestone (606 & PLUSMN; 74 g kg(-1)) was higher than in other soils. The available silicon content was the lowest in granite (51 & PLUSMN; 15 mg kg(-1)). It was closely correlated with available cadmium while being mainly influenced by soil pH, organic carbon, and bulk density. The prediction model of available Si established using a random forest had the highest accuracy (R-2 = 0.74). Widespread deficiency in available silicon content in plough layers of paddy soil in mid-subtropical China highlights the importance and value of higher silicon fertilizer input in soils.
