Purple Spike (shrubby falseindigo)

a species of bean family, the name Amorpha fruitcosa L., perennia leaves thickened with small shrubs. Also known as mian, dragonfly, alfalbo, purple verdant. It is a good crop of green manure and stem strips. Native to the eastern, central and southern United States, as well as Mexico, the world's continents are also planted. Garden plants are planted in Shanghai, China.root system developed, one year live seedlings, the main root can be deep into the soil layer 0.7m, the horizontal root length of 1m, 3 years of root growth in more than 1m, the root system has 70-80% distributed in the soil layer within 0.6m. Roots have no germination ability and cannot be reproduced by rooting method. Stems are straight stems, no branches, strong germination force, after cutting, the root of the old branch can germinate 2-4 stems, continuous low cut 3-4 times on the base of the plant, can germinate 20-30 stems. Leaves are oddly numbered plume-like compound leaves, leaf egg circles or oval shapes, full edge, mesh leaf veins. Spike-shaped total flower sequence, flowers in full bloom has a fragrance, is a good source of honey, black purple or purple blue, flag petals inverted egg shape, rolled into a barrel-shaped, wingless petals and dragon bone petals, fruit curved moon shape, ripe for sepia, tumorous glandular cells, hidden volatile oil, flavor oil essence about 2.5%, can be used as flavoring raw materials. Seeds tawny, waxy luster and special odor, a thousand grains weigh about 20g, oily about 10%, can extract oil essence and grease. Salt-resistant alkali, which can grow normally when the salt content of the root soil is 0.3-0.5%. Drought-resistant, water-resistant, regenerative and circumcision-resistant. Each breeding method directly nursery transplant and seeding, generally to spring sowing as a good, such as sufficient soil moisture, spring sowing and summer sowing can be.Where the seed breeding, before planting must be seed treatment, by using grass ash water or salt water, can also be soaked with warm water, soaked seeds, with clean water, can be directly sown. Strip breeding to the rainy season is appropriate, the selection of two or three years of raw branches, in which the lower part cut into 15-20cm inserts for planting. Line spacing is generally more than 1m, plant distance is 50-100cm.general fresh leaves contain 67.9-74.1%, N 0.68-0.90%, P2O5 0.09-0.14%, K2O 0.39-0.44%. Fresh leaves contain coarse
protein
21.58 percent, coarse fat 5.55 percent, coarse fiber 11.1 percent, soluble nitrogen-free leachate 41.9 percent, and gray 5.72 percent. Aging stems can be used for weaving, water conservancy construction and packaging materials, but also the paper industry and man-made fiber raw materials.
