山西省山区面积占全省总面积的80％,植被稀疏,土壤贫瘠,水土流失严重,生态严重失调。1980年以来,省科委组织的全省飞播协作组在忻州、吕梁地区进行了飞机播种草灌木试验,取得了成功。在此基础上我们组织了试验推广,三年来共推广飞播面积16.8万亩,取得了较好的效果。 Shanxi mountainous area accounts for 80% of the total area of ​​the province, with sparse vegetation, poor soil, serious soil erosion and serious ecological imbalance. Since 1980, the provincial airborne cooperative group organized by the Provincial Science and Technology Commission has conducted pilot tests of seeding grass and shrubs in Xinzhou and Luliang areas with success. On the basis of this, we organized a pilot project to promote a total area of ​​16.8 million mu over the three years and achieved good results.
