宁南黄土丘陵区灌木林生产力的研究
- Title:
- Study on Productivity of Shrubberies in Loess Hilly Region of South Ningxia
- Keywords:
- loess hilly area; shrubberies; productivity
- 摘要:
- 上黄试区位于黄土丘陵区西部，光照充足，气候干燥，土层深厚，常年干旱少雨，水资源不足，土壤肥力差，水土流失严重.直接影响农、林、牧业的持续发展.为此，笔者在承担国家“八五”科技攻关项目的林草治理与研究工作中，针对这一问题选择了适宜该试区生长的优良灌木柠条（Caragana korshinskii）、沙棘（Hippophaer hamnoicles）、山桃（Prunus davidiana）进行了生长与产量变化的试验研究，为该试区灌木林的建设与发展提供依据.
- Abstract:
- Shanghuang experimental area is situated in the west part of the loess hilly region, which is characterized by sufficient sunlight, arid climate, deep soil thickness, usually little precipitation, lack of water resources and poor soil fertility.These unfavourable factors affect effective development of agriculture, forestry and animal husbandry.In view of this, under the study and harness of forest and grass that the author undertaked about state scientific and technuological project during "85", by choosing tree species Caragana korshinskii、Hippophaer hamnoicles an Prunus davidiana, etc., which grew suitably in this area, there was astudy and experiment of variation of growth and yield, so that basis was provided for construction and development of shrubberies.
