为缓和宁南黄土丘陵区“三料”俱缺的现状,以控制水土流失和使农民脱贫致富,在固原县河川乡黄河村建立“三料”灌木林试验基地。试验项目有:二色胡枝子引种、刺槐矮林作业、连翘引种、达标优良灌本种的筛选、万亩“三料灌木林基地的建立及宁南黄土丘陵区灌木林资源调查等。试验结果取得了良好的生态经济效益:种植的草灌已开始发挥水土保持作用,整个基地年产“三料”754.5t,正逐步发挥绿色能源和种子基地的作用。今后任务是加强林木抚育管理,深入探索灌木林营造和利用规律,提高灌木林质量。
'FFF' shrub forestry basis is founded at Huanghe Village, Hechuan Commune, Guyuan County in order to moderate 'FFF'shortage of Loess Hilly Region of southern Ningxia, to control soil and water erosion and make farmers get rid of poverty and become rich. Following experiments are included: Lespedeza bicolor seed introducing, working of Robinia pseudoacacia short forestry.
