Seed treatment of Robinia pseudoacacia

Last Updated: 2024/11/22, The dry Robinia pseudoacacia seed is very hard, the seed cortex is dense and the water permeability is poor. Robinia pseudoacacia seeds are often used in production with 50 ℃ warm water, but the effect is not as good as that of boiling water. The operation steps are as follows: pour the boiled water into the water tank or other container, the amount of water injected is about 1/2 of the container. Put the Robinia pseudoacacia seeds into boiling water. Keep stirring the boiling water with the plank so that the seeds of Robinia pseudoacacia are heated evenly in the boiling water. After stirring for 5 minutes, quickly add cold water to cool down, and the water temperature will not be hot. Fish out the blighted seeds floating on the surface of the water and soak the seeds in warm water for 24 hours. The next day, dump it.

The dry Robinia pseudoacacia seed is very hard, the seed cortex is dense and the water permeability is poor. Robinia pseudoacacia seeds are often used in production with 50 ℃ warm water, but the effect is not as good as that of boiling water. The steps are as follows:

Pour boiled water into a tank or other container. The amount of water injected is about 1/2 of the container. Put the Robinia pseudoacacia seeds into boiling water. Keep stirring the boiling water with the plank so that the seeds of Robinia pseudoacacia are heated evenly in the boiling water. After stirring for 5 minutes, quickly add cold water to cool down, and the water temperature will not be hot. Fish out the blighted seeds floating on the surface of the water and soak the seeds in warm water for 24 hours. The next day, the dirty water was poured out, and the swollen Robinia pseudoacacia seeds were washed out by rice panning method, and the seeds were germinated under the condition of 20 ℃ to 25 ℃. Repeat the above method, and then use boiling water to treat Robinia pseudoacacia seeds without water absorption. Breathing during germination can cause the seeds to produce high temperature and mucus. Therefore, rinse Robinia pseudoacacia seeds with warm water that is not hot once or twice a day. Rinsing keeps the seeds moist and clean and avoids mildew. After sprouting for 5 to 7 days, more than 1/3 of the seeds will crack and grow white radicles, which is called whitening in production. From late March to early April, the exposed seeds of Robinia pseudoacacia were sown in the nursery, and the seedlings of Robinia pseudoacacia will grow after 7 to 10 days. Compared with the warm water soaking method, the hot seed method is simple and easy to operate; the water absorption expansion rate of one-time hot seed is more than 95%, which is 20% to 30% higher than that of warm water soaking seeds, and the high temperature hot water has the effect of disinfection and sterilization, and the incidence of standing blight at seedling stage is low.
