神池县把大种柠条作为治理水土流失和治穷致富的基础工程来抓,截至1995年底止,全县共发展柠条种植面积1.53万hm2,使林草覆被率由1982年的12%上升到41%。种植柠条锁住了风沙,年最大风速由70年代的29.7m/s降到7.8m/s,大风日数由84天下降到10天以下,土壤侵蚀模数由0.89~2.2万t/km2下降到0.6~0.9万t/km2,降水量由441mm上升到487.7mm。依托柠条大力发展养殖业,全县农户户均达到7.2只羊,年人均养羊收入达180元以上,收入高者达3000元。种植柠条改变了农村肥料、饲料、燃料俱缺状况,使人们思想观念发生了深刻转变,促进农业走上生态、经济同步发展的新路。
Shenchi County, a large species of Caragana as a basic project to control soil erosion and get rich and get arrested, as of the end of 1995, the county a total of 15,300 hm2 of kelp planted area, so that forest coverage rate from 1982 12% to 41%. The planting of Caragana intercropped sandstorms. The annual maximum wind speed dropped from 29.7m / s in the 1970s to 7.8m / s. The days of strong winds dropped from 84 days to 10 days and the soil erosion modulus was 0.89 ~ 2. 20,000 t / km2 down to 0.6 to 0.9 million t / km2, precipitation increased from 441mm to 487.7mm. Relying on the development of aquaculture Caragana, the county average per household reached 7.2 sheep, sheep per capita annual income of 180 yuan, the highest income of 3,000 yuan.
