Advances in the Study of Mineral Nutrients and Fertilization of Castanea mollissima BL.

Mineral nutrients are key factors in raising yield and improving quality of Chinese Chestnut (Castanea mollissima BL.). The relationship between mineral nutrients such as Nitrogen, Phosphor, Potassium, Boron and Calcium and growth of Chinese chestnut was reviewed in this paper. Leaf analysis on Chinese chestnut, relationship between plant nutrient metabolism and fertilization time as well as the quantity and methods of fertilization on Chinese chestnut were summarized, the establishing of nutrient diagnosis criteria and scientific fertilization scheme of Chinese chestnut was suggested.
