柠条具有很高的生态和经济效益,是陕北丘陵沟壑区植物治理措施的主要灌木树种,近几年又有大发展。国家重点治理区之一的无定河流域,种植的柠条占到总治理面积的40％以上。但是,由于柠条造林多年沿袭传统直播方法,虽简单省工,但受干旱气候、自然条件等不利因素制约,造成成活率低、保存率低、综合效益差的问题相当突出,已直接影响到造林质量和治理成果的巩固。因之,尽快采取有效措施,提高柠条造林质量与效益,对陕北丘陵沟壑区的治理与开发具有十分重要的意义。
Caragana has a high ecological and economic benefits and is the main shrub species for plant control measures in the hilly and gully regions of northern Shaanxi. In recent years, there has been a great development. One of the key state-controlled areas of the Wudinghe River, the planting of the Caragana accounted for more than 40% of the total area under management. However, since the traditional direct seeding method of Caragana korshinskii for many years followed the traditional methods of direct seeding, it is simple and labor-saving. However, due to the unfavorable factors such as arid climate and natural conditions, it causes the problems of low survival rate, low preservation rate and poor comprehensive benefit, Afforestation quality and consolidation of governance outcomes. Therefore, as soon as possible to take effective measures to improve the quality and effectiveness of Caragana korshinskii afforestation is of great significance to the governance and development of the hilly and gully regions of northern Shaanxi.
