Native species up to 20 m tall tree, cultivars vary in height, bark dark gray, irregularly longitudinally fissured; winter buds 5 mm long; young branches reddish-brown, hairy, older branches glabrous, grayish-brown, lenticels conspicuous.

Chestnut is the common name, the name comes from the "Chinese Tree Taxonomy"; its official Chinese name in the "Chinese Flora" recorded as chestnut; aliases are chestnut, kui chestnut, hairy chestnut, oil chestnut, hairy chestnut, and so on; belongs to the shell family chestnut deciduous trees in plant taxonomy. Chestnut native species in China in the north and south are distributed.

The chestnut is a relatively tall tree fruit trees, growth and results have two main features a strong light-loving; two is a strong branch results. Chestnut generally by the result of the parent branch of the apex of the shoots of the fruiting branch results, strong fruiting branch is not only the formation of yield, but also to expand the crown and cultivate the main branches of the backbone branch. Plastic surgery and pruning should be aimed at promoting growth.

Spring sowing method

Spring sowing time: spring sowing time is generally mid-February to early April, due to the chestnut seed in the storage process is easy to sprout, the general sowing should be on the early side. If the seeds can be stored at low temperatures, it is appropriate to late sowing is better, which is conducive to the rise in soil temperature, shorten the seed burying time, reduce losses, and can be neat and consistent seedlings.

Nursery site selection: nursery site selection land flat, fertile slightly acidic sandy soil. Fertilizer before land preparation, and then do the seedbed, seedbed width 1-1.2 m, length 5-10 m, seedbed is about 15 cm above the surface of the ditch, and remove weeds. Sowing is done in longitudinal rows, with row spacing of 30-40 centimeters and plant spacing of 10-15 centimeters, with a seed volume of 100-150 kilograms per mu.

Spot sowing: sow the seeds flat, the apex should not face up or down to facilitate seedling emergence, then cover the soil 3-4 cm, and a little compression. In order to ensure the supply of soil moisture, before sowing to fill the bottom of the water, 2-3 days after the soil is moist but not too sticky, easy to operate when the furrow sowing. From sowing to seedling stage do not water montage water, so as not to affect the emergence of soil crust.
