Do you know how to reproduce the leaves of Sophora japonica? Simple skills can be learned by rookies.

Locust trees can be called Robinia pseudoacacia, White Robinia pseudoacacia, Fine-leaf Robinia pseudoacacia and so on. They have many aliases, but they are called differently in places where they are not used. Originally produced in China, it is common in North China and plateau areas of China, where the climatic environment is more suitable for its growth. The locust tree has no requirements for the growing soil and does not need any skills when planting. It is a light-loving plant, which can grow in cold winter and shady places, and its roots take root in the depths of the soil. Today we are going to learn how this unskilled locust tree propagates.

I. the method of root-burying reproduction

Root species can be introduced at the stage of falling leaves of locust trees. Before planting, the root system can be preserved well with sandy soil. The humidity of sandy soil is very important, if it is not controlled well, it will affect the preservation quality of root system. The soil should not be too dry will cause root dehydration, and it should not be too wet, otherwise it will become moldy and rotten.

There is still a difference in the time period for raising seedlings between the north and the south. Generally speaking, seedlings can be raised in the south in March, while in the north, seedlings can only be raised between the end of March and the beginning of April. When raising seedlings, it is necessary to select the root segments that have grown for more than a year, and they have not been bitten by insect pests. Each section of the root system should be planted in the soil to control the distance between, not too close. After the root system is put away, it is covered with sand, watered and moisturized, and then covered with plastic film, and the seedlings can be seen breaking out of the soil in a month.

2. Cutting propagation method

The time period of locust tree cutting is not much different from that of root-burying propagation, or it can be a little earlier. If the locust tree wants to use the method of cutting to propagate, it must first choose good cuttings, generally choose hard branches, soft branches are not suitable, its growth ability is not as strong as hard branches, cut the selected hard branches into more than ten centimeters long, the upper incision is flush, the lower incision is inclined, and apply rooting powder at the lower cut or soak it in the rooting solution. In this way, it can accelerate the rooting speed of cuttings and greatly improve the survival rate of cuttings. Cuttings to be cut into the ground is similar to the method of root-burying reproduction, also to control the distance between cuttings, be sure to remember that it is oblique into the soil, do not make a mistake.

3. Sowing and breeding method

Seed propagation in order to improve the germination rate of seeds, it is generally necessary to deal with seeds before entering the pot. There are two methods for the treatment of locust seeds, which are as follows:

1. Put the seeds in a bottle of warm water, keep stirring until the temperature of the water drops, and then leave it in a sunless place for a day. You will find that most of the seeds will swell. Take out the swollen seeds and store them on wet paper. When you see the seeds germinate, you can sow them in the soil. And those seeds that do not expand should not be discarded immediately. You can soak in water several times. If there is still no expansion, it is not too late to discard them.

two。 The seeds are soaked in water for a day, then taken out and kept directly in fine sand. Soaking in water is to increase the water content of the seeds so that they can sprout and grow in fine sand. Generally preserved in fine sand for half a month can be dug up for inspection, half of the seeds have signs of germination can be planted with sand.

Locust tree sowing is generally carried out in the spring, after sowing to press the soil to water, so that the seeds are closely combined with the soil, if conditions permit, can also be covered with film.
