Seedling (that is, normal planting) chestnut trees bear fruit in 5~8 years, and chestnut trees enter the peak of fruit bearing in about 20 years.

Requirements of chestnut on environmental conditions

Chestnut is one of the earliest economic tree species cultivated in China, and it likes light. It can be cultivated in soil with pH of PH4.5-7.5, with an annual average temperature of over l0 degrees, an average growth temperature of 16-20 degrees, and a minimum temperature of minus 25 degrees in winter. Chestnut has strong adaptability, wide distribution, easy cultivation and high yield, and can be cultivated economically in mountainous areas and beaches.

Cultivate strong seedlings

Seed treatment: Chestnut seeds are afraid of dryness, heat and freezing. After seed selection, it is fumigated with aluminum phosphide to kill insects, disinfected with 100 times methyl thiophanate solution, and stored in a clean and humid river sand layer after seed treatment.

Sowing: from early March to early April, sow at a spacing of one foot and five or six inches. It is required that the stem of the seedling in that year is more than 0.8 cm thick, the height of the seedling is more than 1 m, the root system is developed, and the seedling per mu is 1 10,000 plants.

Timely grafting: chestnut branches contain a lot of tannins, so grafting is not easy to survive. It is necessary to choose a good time and pay attention to grafting methods to improve the survival rate. Autumn August-10, suitable for bud grafting. Splitting and cutting can be carried out 20 days before germination and before the juice is fully circulated in spring. However, subcutaneous grafting should be carried out about 20 days after the newly grown leaves and juices flow fully. Scions should be picked as early as possible before germination, stored in the sand in the shade at low temperature, and stored in the refrigerator if possible.
