Because the shell of Carya cathayensis seeds is too thick, it takes us a lot of snacks to plant them. The first thing is to accelerate the germination of seeds. Because of the shell thickness, it is difficult to germinate without accelerating the germination, which greatly reduces our germination rate.

Usually we use the method of accelerating germination by soaking in cold water. First, put the seeds of Carya cathayensis in a big container, which can be a cylinder or a barrel, and then fill it with water to prevent the seeds from floating up. We have to press the seeds under water with heavy things, and the soaking time can be based on whether the seeds have cracks or not, usually about ten days. When accelerating germination, the soaked water should be changed every day.

We can choose to sow the hickory that has been germinated in spring. If it is sown in spring, it should not exceed March at the latest. We can sow the hickory by drilling, and the maximum spacing can be kept at 20 cm. Put the seeds into the hole horizontally, and cover the surface with a straw mat after sowing, which can not only keep moisture, but also prevent soil hardening, because soil hardening will lead to the failure of seedling germination.
