How many chestnut plants are planted in one mu of land?

The planting density of Chinese chestnut varies from region to region. General plain chestnut orchard should be 30-40 plants per mu, mountain chestnut orchard should be 40-60 plants per mu, and planned dense planting chestnut orchard can plant 60-111 plants per mu.

Nursery management of Chinese chestnut:

1. Maintain the temperature and humidity in the plastic shed

When the temperature in the shed rises to 30 ℃, immediately uncover the plastic film on both sides of the shed at the same time, ventilation and cooling, the relative humidity in the shed is kept above 90%. When the humidity is not reached, spray water every 3-5 days, and it is appropriate to keep it foggy.

two。 Refining seedling

Seedling refining is the main measure to promote the development of grafted seedlings and improve the quality of seedlings. The seedlings can heal in 10-15 days after grafting, and 2-3 leaves can be released in 20 days. At the end of April, the daily average temperature has reached more than 15 ℃, so seedlings should be refined. At 1: 00 p. M. on a sunny day, all the film will be uncovered and covered before sunset, gradually increasing the exposure time of the sun to the seedlings. After 5-7 days of seedling refining, the plastic film can be removed.

3. De-adorning

In order to accelerate the healing of the grafting interface and improve the survival rate, the adventitious buds on the rootstock should be erased in time, and do not rush to cultivate seedlings to sprout, which will affect the healing, germination and growth of grafted seedlings, even if the scion does not survive, only one sprouting can be left to promote the growth of grafted seedlings.

4. Strengthen the management of water and fertilizer

After uncovering the shed, the seedlings should often loosen the soil and weed, water in time, apply fertilizer every 10-15 days from June to July, and apply fertilizer 3-4 times during the whole growing period. Be sure to open ditches for fertilization or low concentration spraying, applying 4-5 kg urea per mu, and watering immediately after application. do not affect the growth of seedlings. At the same time, pay attention to drainage in flood season.

Reasonable close planting is one of the basic measures to increase the yield of chestnut trees, so we should determine the planting density of chestnut orchards according to the field conditions.
