It is an ideal tree species for urban fragrance, beautification and greening. Robinia pseudoacacia can also be cultivated in desert areas, so it is a tree species to prevent wind and sand fixation and prevent soil erosion. The tree blossoms twice a year in the north, each time in May, the flowering period is about 20 days, and the second flowering is in July, the flowering period is about 40 days.

Pay attention to distinguish between true and false in the introduction of Robinia pseudoacacia
At present, there are four kinds of false inferior Robinia pseudoacacia seedlings sold in the market: (1) Safflower Robinia pseudoacacia instead of Robinia pseudoacacia. The Corolla of Robinia pseudoacacia and Robinia pseudoacacia are both butterfly-shaped purplish red. Safflower Robinia pseudoacacia blossoms once a year, bears pods and is grafted with Robinia pseudoacacia as rootstock. Robinia pseudoacacia blossoms twice a year, does not bear pods, and propagates in root segments. (2) aged seed root. The seed root of perennial Sophora japonica has a very low germination rate due to aging. According to the trial planting, the roots of Sophora japonica for more than two years should not be used as seedlings, let alone in the market.

Introduction of a new variety-tetraploid Robinia pseudoacacia
Tetraploid Robinia pseudoacacia, a new polyploid variety of Robinia pseudoacacia, originated from South Korea and was introduced into China in recent years. At present, five series numbers have been introduced and cultivated, which can be divided into two types: fast-growing wood type and feed type. According to the analysis of the experimental results, compared with the common Robinia pseudoacacia clones, the main characteristics of tetraploid Robinia pseudoacacia clones are as follows: the fast-growing wood type of ① is similar to that of common Robinia pseudoacacia clones, but the rapid growth is more obvious. The height of annual grafted seedlings can reach 3 meters, the ground diameter is 3.5 cm, and the height of 3-year-old trees is 5 meters to 7 meters, and the DBH is 6 cm to 9 cm. The 18-year-old tree is 19 meters tall, with a DBH of 24.5 cm and a single tree volume of 0. 5 cm.

Cultivation and Management of Robinia pseudoacacia
First, the method of propagation is easy to reproduce, burying roots, cutting, grafting, or digging roots to propagate. The main and lateral roots of 1-year-old and 2-year-old Sophora japonica were selected for root-burying propagation, and the suitable diameter was 0.3-1.5 cm. 1012kg per mu of roots are needed, and 300kg / kg of roots can be cut 400 segments. Two methods of transplanting seedlings in greenhouse and burying roots in field can be selected. The indoor seedling was raised in different areas and the seedling raising time was different, so it was transplanted into the field in the middle of May. Burying roots in the field will be carried out when the lowest outdoor temperature is more than 10 ℃.
