汉中地区位于陕西南部东经105°30′00″—103°24′37″,北纬33°15′15″—33°56′77″,年平均温度13.4℃,年平均雨量在800～1200毫米左右,境内海拔在449.7～3000公尺,天麻主要分布在秦岭,巴山山区。几年来,我们根据当地自然条件,从七○年变野生为人工栽培,不断地研究改进栽培技术,在海拔449.7公尺的平川和海拔2000公尺左右的高山区都栽培成功,获得了较好的成果,重点产区空窝率由57％降到1.1％,平均窝产由四两一钱,提高到四斤一两(5～7根棒/窝)。 The Hanzhong area is located in the southern part of Shaanxi Province with longitude 105 ° 30’00 “-103 ° 24’37” and latitude 33 ° 15’15 “-33 ° 56’77”. The annual average temperature is 13.4 ℃ and the annual average rainfall is about 800 ~ 1200 mm , The territory of the elevation of 449.7 ~ 3000 meters, Tianma mainly distributed in the Qinling Mountains, Bashan mountains. In recent years, according to the local natural conditions, we have changed from 70 years of wild to artificial cultivation. We continuously study and improve cultivation techniques. We succeeded in cultivating a plain at an elevation of 449.7 meters and a mountainous area at an altitude of about 2000 meters, and obtained better results The results showed that the key producing areas had dropped from 57% to 1.1%. The average litter yield increased from 42% to 4 pounds (5 to 7 rods / litter).
