Robinia pseudoacacia mainly exists in the form of street trees in China, which can provide a certain amount of locust rice for use in the field of medicine. So where is the locus pseudoacacia produced? When is the best time to plant?

Where is the origin of Robinia pseudoacacia?

1. The origin of Robinia pseudoacacia

Robinia pseudoacacia comes from northern China and has a wide range of producing areas. It is cultivated in the south of Northeast China, South China and Southwest China, among which the Loess Plateau and North China are the most common. More famous are Jingchuan, Pingliang, Gansu, Wuzhong City, Ningxia, Xuchang, Henan and other places. In addition, there is also a small amount of distribution in Japan and Korea.

Specializing in the production of locust rice for the medical field.

2. The growth environment of Robinia pseudoacacia

Sophora japonica is cold-resistant, sunny, drought-resistant and not resistant to shade and dampness. The growth environment of Robinia pseudoacacia is very different from that of other trees. Robinia pseudoacacia is not very picky about the choice of soil, but it will grow better in fertile soil. the choice of suitable soil will provide a good environment for the growth of Robinia pseudoacacia, and the growth of Robinia pseudoacacia will be more healthy and coarse.

Therefore, Robinia pseudoacacia is about planted in the north, and its cold-resistant growth habits and requirements for the growth environment are not very high.

When is the best time to plant Robinia pseudoacacia

1. Planting time of Robinia pseudoacacia

It is best to plant Robinia pseudoacacia from March to April every year, and when planting, we should pay attention to trim the root system, cut off the rotten roots, and do not leave side branches, which will affect the growth of the trunk and grab the nutrition needed for the growth of the trunk. It should be planted at any time, not overnight and frozen, and the frozen seedlings will evaporate the next day, which is not conducive to the growth of Robinia pseudoacacia.

2. Selection of Robinia pseudoacacia seedlings.

In addition, because the survival rate of Robinia pseudoacacia is relatively low, it is particularly important to choose seedlings. The seedlings of Robinia pseudoacacia should be free from insects and diseases, with complete root system and fresh seedlings. And it should be pruned before cultivation, pruned to a specified length before cultivation.

3. Planting methods of Robinia pseudoacacia.

Robinia pseudoacacia seedlings to ensure the survival rate, if the survival rate is low will bring economic losses for growers, increase the cost of planting, so, to choose experienced growers.

In terms of planting methods, Robinia pseudoacacia can not be planted overnight, and there are a lot of skills when covering the soil. When filling, it is necessary to separate the ripe soil from the underlying raw soil, and cover the mature soil first and then fill the raw soil.

They often eat up the leaves, which further leads to the weakness and even death of Robinia pseudoacacia trees, so prevention and control should be strengthened.
