Seed treatment of Robinia pseudoacacia
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.

The method of accelerating budding and raising seedlings of Robinia pseudoacacia
Robinia pseudoacacia is resistant to drought, barren and growing fast, so it is a good tree species for greening and afforestation in rural areas. If the root segment budding method is used to raise seedlings, not only the cost is low, the operation is simple, but also the seedling quality is good. First, select the land to make the bed and choose the nursery land with leeward and sunny direction, flat terrain and good drainage and irrigation as the hotbed. Before making the border, 1000 kg of organic fertilizer, 50 kg of ammonium bicarbonate and 50 kg of calcium superphosphate were applied per mu. After ploughing and raking, 100 ∶ 1 wheat bran and methamidophos bait were sprinkled on the border surface to prevent mole cricket and other underground pests. The border faces from north to south, 1.5 meters wide and 12 meters long.

Shaping and pruning of Robinia pseudoacacia
Robinia pseudoacacia is an excellent tree species for afforestation and afforestation in our province because of its fast growth, strong adaptability and excellent quality. But Robinia pseudoacacia sprouting is very strong, if not pruned, it will grow full of branches, not ventilated, thus affecting the growth rate. According to the observation, the average annual growth of Robinia pseudoacacia after correct pruning is 72cm, while that of no pruning is only 49cm, which is pruned continuously, which is 3-5 years earlier than that without pruning. In order to achieve this goal, attention must be paid to shaping and pruning. Under the condition of natural growth, Robinia pseudoacacia has strong branching ability and exuberant growth.
