The twigs of Catalpa spinosa have coarse spines, the leaves are alternate on long branches, clustered on short branches, the leaves are nearly rounded, the lobes are triangular round-ovate to oblong-ovate, the umbels form a terminal panicle with slender filaments, the fruit is nearly spherical, flattened, and the flowering and fruiting period is from July to October. It is a poisonous plant recorded in the Chinese Plant Atlas Database, but their leaves do not actually contain toxins, but they should be careful when picking. The wood is hard and straight, and is used for building materials, furniture and railway sleepers.

Catalpa will also have seeds, which is also the embodiment of the continuation of life by Catalpa. Scientists have found that the seeds of their knots are high in oil, so they can be made into soap and laundry detergent, and they are natural pure green plant seeds that do not harm hands and clothes. Rapid growth and strong adaptability are the characteristics of the tree, but the tree with such characteristics has actually become an endangered tree species.

The environment they live in has been destroyed by humans, and it is also due to overexploitation. Because of its high quality, it has become the preferred wood for merchants, so even if the growth ability of the catalpa is strong, it cannot keep up with such frequent felling.

Cultivation techniques. The propagation of Catalpa spinosa is mainly based on sowing, picking after the fruit is ripe in autumn, taking out the seeds for sand storage, and outdoor furrow sowing in the spring of the following year. In addition, root cuttings can also be used for propagation.

In addition to seed propagation, wild catalpa mainly reproduces by underground transverse stems. In artificial cultivation, cuttings, strip pressing and seed propagation methods are mostly used, but rooting is difficult, and the requirements for treatment are not easy to master, which is not as good as seed propagation. The seed propagation method is simple and easy, and a large number of seedlings can be obtained in a short period of time.

Methods of reproduction

1. Sowing

Seeds are harvested on sturdy mother trees that are 15-30 years old. In March, spring sowing is adopted, soak the seeds in 30 degrees warm water for 4 hours before sowing, remove them to dry, and then mix them evenly with 3-5 times the wet sand of the seeds, pile them in the house for germination, and regularly sprinkle and turn them to make the internal and external temperatures uniform. After about 10 days, 30 seeds can be sown when there are 30 cracks.

Strip sowing is adopted, the row spacing is 20-25 cm, and the sowing amount per mu is 1-2 kg.

2. Cuttings

Select 1-year-old seedlings to make seed strips, cut into 15-20 cm cuttings, tie every 50 or 100 cuttings into a bundle, erect in the open sand pit, a layer of cuttings, a layer of wet sand, to the pit mouth 20 cm to cover the soil, when the weather is cold, the soil layer should be thickened. Straw handles are erected every 1 meter in the pit on rollers to facilitate aeration. In early spring, it is necessary to check frequently to prevent the rise of ground temperature and mildew of cuttings.
