In addition, it also contains fat, calcium, phosphorus, iron, a variety of vitamins and trace elements, especially vitamin C, B1 and carotene, which are higher than ordinary dried fruits. Chestnuts are nutritious. In addition to rich starch, it also contains monosaccharides and disaccharides, carotene, thiamine, riboflavin, ascorbic acid, protein, fat, inorganic salts and other nutrients. Morphological characteristics: chestnut is a general designation of trees or shrubs of the genus Castanea in the composite family (Fagaceae), with about 7-9 species. Chestnuts are usually divided into two kinds: Wild chestnuts and hybrid improved chestnuts. In China, the improved varieties usually planted are hybrid cultivation. Because of their size, sweetness and strong disease resistance, they are widely planted in China. Chestnuts are native to temperate regions of the northern hemisphere. Most chestnut trees are 20 to 40 meters high, deciduous trees, and only a few are shrubs. All kinds of chestnut trees have edible nuts, single leaves, oval or oblong, 10 ~ 30 cm long and 4 ~ 10 cm wide, with brush like teeth on the edge. Monoecious, the male flowers are erect soft Kin flowers, and the female flowers are born in only one or more species. Nuts are hidden in dense spinous processes, with a diameter of 5 to 11 cm. There are 1 to 7 nuts in one capsule. The flowering period is from May to June, and the fruit ripening period is from September to October.

Usually, the leaves are elliptic to elliptic, 11-17 cm long, 7 cm wide, and the top is short and acuminate. The base is almost truncated or round, or both sides are slightly bent inward to form earlobes, usually on one side. The base of the new leaf is inclined and asymmetric, usually narrow and symmetrical on both sides. The back of the leaves is starlike attached to the villi or becomes almost hairless due to hair loss; Petiole is 1-2 cm long. The leaves are alternate, thin and leathery, the edges are sparsely serrated, and the ends of the teeth have inward curved bristles; Short petiole with short hair and short hair. Luotian chestnut flowers are unisexual and monoecious. The male flower is an upright soft Kin inflorescence, born in the leaf axil of the lower branch, about 15 ~ 500px, light yellowish brown. Female flowers are sessile, born in the lower part of the male inflorescence, female flowers have shells outside the total VO, separate or 2-5 female flowers are born in the total Luc, and the ovary has six compartments. The male inflorescence is 10-20 cm long, and the inflorescence is hairy. 3-5 flowers are clustered, female flowers 1-3 (-5) are well developed, and the lower part of the style is hairy. Chestnuts are spherical in shape, with sharp burrs on the outside and 2-3 nuts inside, which are divided into four petals when mature. The nut is dark brown, with a diameter of 2 ~ 75px. The spines of mature crustaceans are long and short, sparse and dense. When dense, the outer wall of the crust is covered. When the outer wall is sparse, the outer wall is visible. The diameter of spines in the earth's crust is 4.5-6.5 cm; The height of the nut is 1.5-3 cm and the width is 1.8-3.5 cm. It blooms from April to June and from August to October.
