柠条(Caragana korshinskii Komaro-r)又名锦鸡儿,是我区水土保持的重要灌木树种之一,也是良好的薪炭林树种。嫩枝叶是很好的家畜饲料,也可作肥料。它耐寒,耐高温,并极耐干旱、瘠薄,在-32.7℃的严寒,冻土层达1.28米的条件下,生长良好;地温高达55℃时,不见日灼,根系发达,当年生苗木根深达0.7米,在干燥的固定沙丘和深厚的黄土坡上,垂直主根特别明显,7年生主根长达4.49米。近年来,我区从实际出发,把大种柠条作为改变黄土丘陵沟壑区自然面貌和经济面貌的一项战略措施,1982年全区共种植120万亩,累计保存面积330万亩,在保持水土和经济效益等方面取得了显著成效。我区广
Caragana korshinskii Komaro-r, also known as Caragana, is one of the important shrub species for soil and water conservation in our region and is also a good firewood tree species. Tender leaves are good feed for livestock and can also be used as fertilizer. It is cold-tolerant, high-temperature tolerant and very resistant to drought and infertility. It grows well under the condition of -32.7 ℃ in cold and frozen soil layer of 1.28m. When the ground temperature is as high as 55 ℃, it does not show sunburn and roots are developed. Up to 0.7 meters, in the dry fixed dunes and deep loess slope, the vertical main root is particularly obvious, 7-year-old main root up to 4.49 meters. In recent years, our district has set out from reality as a strategic measure to change the natural appearance and economic outlook of the gully areas of the Loess Plateau. In 1982, a total of 1.2 million mu of land was planted and the accumulated area was 3.3 million mu, Water and soil and economic benefits have achieved remarkable results. My area is wide
