The hedgehog, also known as the artichoke, is relatively drought-tolerant and can grow normally on the dry slopes and sands in North China and northwest China. It is a good material used in North China and Northwest China to keep water, soil, wind, sand, and green trees on all sides. Now introduce the breeding technology of Robinia pseudoacacia: Robinia pseudoacacia is commonly used for seedlings. First, seed treatment. There are different amounts of hard particles in the seed of Robinia pseudoacacia. It is better to use gradual warming and multiple seed soaking methods, that is, first soaking in water at 60°C, cooling naturally, and after leaving for 24 hours, removing the expanded seeds; for unexpanded seeds Then, soaking in water at 80°C, and then cooling, the removed swollen seeds are covered with wet sacks or straw mats, stuffy germination, 1.5-2 days after the seeds germinate to sow. Second, sowing. Sowing period is from late March to early April. Apply organic fertilizer per acre, such as ring fertilizer 3000-5000 kg, drilling, row spacing 40 cm, cover soil 1-1.5 cm, sowing rate of about 4 kg per mu. Third, nursery stocks tending management. Should be early seedlings, Dingmiao late. Generally divided into 2-3 times the seedlings, when the seedling height 15 cm Dingmiao, spacing 10-12 cm, about 10,000 per mu. The root system requires good ventilation and should not be watered. It should be based on the principle of no drought or no irrigation. In the fast-growing period, a small amount of phosphate fertilizer can be applied. Fourth, pest and disease control. The main pests and diseases of black locust are root rot and blight. When the root carp occurs, use 700-1000 times the trichlorfon to open a shallow ditch in the vicinity of the seedling ridge to control the activity. In order to prevent occurrence of blight, irrigation should be controlled and soil loosened. Under normal growth conditions, an average annual seedling diameter of 1.2 cm can be used for afforestation.
