When to plant紫穗槐 (Amorpha fruticosa)
Core content of this article: discussing when to plant Amorpha fruticosa and the experience of green plant maintenance in terms of planting methods and timing. Next, the editor will introduce to netizens.
Amorpha fruticosa belongs to the leguminous deciduous shrub, with a tall and beautiful shape, growing about 4 meters high. It is commonly called cotton槐 (silk tree) or spike flower槐. The flowers are purple, and the leaves of the seedlings are similar to those of acacia. Amorpha fruticosa has high value and is currently one of the important protective plants for domestic water conservancy flood control embankments, expressways, and desert control projects. It also solves the high-quality species for agriculture and animal husbandry feed and fertilizers.
So, how to plant and manage Amorpha fruticosa?
I: Growth characteristics of Amorpha fruticosa:
Amorpha fruticosa is highly adaptable, cold-resistant, drought-resistant, and thin-soil-tolerant. It can grow well in barren mountains, sandy lands, or roadsides, with strong wind and sand resistance and resistance to adversity. It is cultivated extensively in North China, Northeast China, Northwest China, Anhui, Shandong, Hubei, Guangxi, Sichuan, and other major provinces.
II: Planting methods of Amorpha fruticosa:
1. Planting time: Amorpha fruticosa is generally planted from March to May in spring or from September to October in autumn, with differences in planting time between the north and south.
2. Planting method: Choose a sunny, loose-textured, and well-drained plot as the seedbed, maintain soil moisture, disinfect the soil, dig about 30 cm deep, remove weeds, and apply sufficient base fertilizer, such as 500-750 kg of decomposed manure per mu and 15-20 kg of superphosphate or calcium magnesium phosphate fertilizer. The next day, evenly broadcast the seeds, place them in furrows in the form of drilling, cover them with a thin layer of fine soil 1-1.5 cm thick, slightly press them down, then water appropriately, and cover with a layer of straw to keep the soil moist. Generally, seeds can germinate in about 7-10 days.
3. Thinning: When the seedlings are 3-5 cm tall, thinning should be carried out, removing the inferior and retaining the superior, selecting some strong and disease-free seedlings. When the seedlings are 6-8 cm tall, the second thinning should be carried out to facilitate ventilation and light, promoting seedling growth. Transplanting can be done when the plants reach 1 meter in height, with the seedlings lifted and planted immediately, with soil attached to protect the roots to ensure survival rates.
III: Planting management of Amorpha fruticosa:
1. Watering: After sowing Amorpha fruticosa for about a week, seedlings start to emerge. If the bed soil is dry before emergence, water should be supplied in a timely and moderate manner, avoiding excessive watering. After each thinning, water should be supplied in time to prevent the roots from becoming exposed to wind, keeping the surface soil moist but not too wet to avoid seedling elongation or disease occurrence.
2. Topdressing: During the rapid growth period of Amorpha fruticosa, apply 1-2 times of urea, 10 kg per mu, and an appropriate amount of phosphorus and potassium fertilizers to prevent excessive green growth and promote full lignification. Stop topdressing in the later growth stage to ensure the safe overwintering of Amorpha fruticosa.

3. Cultivation and weeding: After the seedlings have emerged, cultivate the soil and remove weeds in time. When weeding, avoid damaging the seedlings by pulling them out by hand. During the growing period of Amorpha fruticosa, cultivate and weed about 3-4 times a year. Keep the soil loose to prevent weeds from competing with Amorpha fruticosa for water and nutrients. Amorpha fruticosa rarely has diseases and pests during growth. If they occur, insecticides and fungicides can be used for timely control.

IV: Utilization value of Amorpha fruticosa:
1. Landscaping: Amorpha fruticosa grows quickly, has a long growing period, straight branches, and lush leaves, which are relatively beautiful. The flowers are fresh and elegant, making it a good ornamental plant. It has strong wind resistance and is the first choice for windbreak forest belts.
2. Forage: Its leaves are abundant and nutritious, although a bit astringent, and are a good forage plant. The leaves can be fed fresh or made into dry powder, serving as an efficient feed for pigs, sheep, cattle, rabbits, and other livestock and poultry.
3. Green fertilizer: Amorpha fruticosa has a strong sprouting ability, extensive root system, and nodules, with a strong soil-improving effect. Fresh branches and leaves are good for fertilizer and can be used as organic fertilizers.
