我是豆科家族中的一员,身躯矮小属落叶灌木。叶子象槐,开紫花,聚集成穗状,由此得名“紫穗槐”。我喜欢在向阳地方生长。是有耐旱、耐寒、耐湿、耐阴、耐脊薄、耐盐碱、耐风蚀、耐沙压的品格。荒山、丘陵、沙地都是安家落户的好地方。人们称我是改良土壤、保持水土的能手。我根部着生根瘤,能固定氮素,增加土壤含氮量。枯枝落叶腐烂后,增加土壤有机质含量。人们测定得知:两年生根部就着有根瘤300～400个、栽植4个月后亩平均固氮8.13斤。亩年落叶300～600斤,多达1,500斤。栽植5年后、土壤有机质含量增加4倍以上。我的侧根发达,细根稠密。在一般土壤条件下根幅达2米,深达70厘米,纵横交错成网状。在风沙流动和水土流失地区,可固沙保土。我能改善粘土的通气性能,降低盐碱土含盐量。我枝繁叶茂、冠幅能接
I am a member of the Leguminosae family, with short stature deciduous shrubs. Leaves like Huai, peach blossom, gathered into a spike, hence the name “Amorphophallus”. I like to grow in the sunny place. Is a drought, cold, wet, shade, spine thin, salinity, wind erosion, sand pressure resistant character. Barren hills, hills, sand are settled in a good place. People call me a master of soil improvement and soil conservation. I root nodules, can fix nitrogen, increase soil nitrogen content. After litter decay, increase soil organic matter content. People measured that: there are root nodules on the biennial 300 to 400, 4 months after planting mu average nitrogen 8.13 kg. Acres of 300 to 600 pounds of leaves, up to 1,500 pounds. Five years after planting, soil organic matter content increased more than 4 times. My lateral root is well developed, with fine roots. In general soil conditions, the root width of 2 meters, up to 70 cm, criss-cross into a network. In the sand flow and soil erosion areas, can be sand and soil. I can improve the aeration performance of clay and reduce the salinity of saline soil. I am flourishing, the crown can take
