Effect of Mountain and Plain Soil on the Quality of Chinese Chestnut

[Objective] The experiment was conducted to study the effect of soil nutrient on Chinese chestnut quality as well as the quality differences between mountain and plain.[Method] TakingMingzhu Chinese chestnut as the research material,differences ofinternal qualityindex of plain-soil and mountain-soil Chinese chestnut were compared,such as water,soluble sugar,soluble starch,protein content and melting temperature.The differences of organic matter content,nitrogen,phosphorus and potassium in plain and mountain soil were also compared.The correlation among Chinese chestnut water,soluble sugar,soluble starch,protein content and melting temperature as well as soil organic matter content,nitrogen,phosphorus and potassiumwere analyzed.[Result] The soluble sugar,soluble starch,protein content of mountain-soil Chinese chestnut were higher than those ofplain-soil Chinese chestnut.However,starch melting temperature of plain-soil Chinese chestnut was higher.In mountainous areas,soluble sugar and soluble starch in Chinese chestnut had negative correlation with soil total phosphorus.And protein content had negative correlation with soil total potassium.Water content in plain-soil Chinese chestnut showed positive correlation with soil total phosphorus,which had reached extremelysignificant level.[Conclusion]This studyhad reference value for downhill plantingofChinese chestnut.
