What are the technical points of chestnut tree planting?

Chinese chestnut is a very delicious and nutritious dried fruit, known as the "king of dried fruit", which has been planted in China for more than two thousand years. The cultivation of Chinese chestnut is also very simple. Many rural families will plant several chestnut trees. Let's take a look at the key points of chestnut planting techniques.

1. Ploughing woodland

Chestnut trees need to be ploughed properly, and the intensity of ploughing should be controlled according to the age of chestnut trees. Young trees only need shallow ploughing, and fruit trees should be turned deeply to promote root growth. And adult fruit trees should be ploughed more than 30 centimeters deep, and be careful not to hurt the roots when ploughing deeply. Clean-up work should also be done before deep ploughing to prevent the outflow of soil and water.

2. Proper fertilization

The fertilizer of Chinese chestnut is mainly organic fertilizer, try not to use chemical fertilizer, because chemical fertilizer will cause great harm to the root. It may burn roots and cause all kinds of insect pests. When applying fertilizer, chestnut trees should be changed and fertilized along the crown. The amount of fertilizer should be controlled according to the age of the tree, and the soil should be cultivated immediately after fertilization to keep the soil fertile, so that fruit trees can better absorb nutrients.

Third, whitening and shaving

If the age of Chinese chestnut is more than 10 years, it is generally necessary to scrape and whiten after harvest, and in areas with relatively low temperatures, it can be appropriately delayed to early spring. There are a large number of diseases and insect pests in the rough skin and warped skin, so scrape the skin in time. Reduce the incidence of fruit trees. The scraped skin should be destroyed and whitened under the tree.

IV. Shaping and pruning

The trees handled are relatively tall, and pruning is also very important for chestnut trees. If the tree is more than 5 years old, the base branches of the fruit tree should be cut off, the withered and dead branches of diseases and insect pests should be cleared, and the dense overlapping branches should also be pruned in time, so as not to affect the flowering and fruiting of Chinese chestnut, and the old branches of old trees should also be cut out to cultivate new main branches.

5. Anti-freezing treatment

After entering winter, the rising trend of chestnut trees will gradually weaken and their leaves will fall. If the temperature in winter is too low, chestnut trees may suffer frost damage, which may affect the chestnut trees through the winter. So before the Chinese chestnut tree leaves should be covered with plastic film, but also have enough base fertilizer. Water properly if the soil is too dry in winter.

The planting of chestnut is relatively simple, that is, the growth cycle is relatively long, it takes 4 to 5 years to enter the full fruit period, planting must have a certain degree of patience.
