我国西部陇南山区普遍存在山地逆温现象。在白龙江干热河谷 ,冬季 1～ 2月逆温层出现在离河谷底相对高度 5 0～ 2 0 0m处。以 15 0m以下出现逆温的频率最高 ,平均强度为 0 .5～ 1.0℃ /10 0m ,最强可达 3.1～ 4 .0℃ / 10 0m。在逆温层不同高度处进行冬栽平菇、金针菇试验 ,结果表明 :在人工调节空气湿度下 ,逆温层栽菇增产增收效益明显 ,且逆温层不同高度处的出菇量存在显著差异 ,以 10 0m高度处出菇量最大
Longnan Mountains in western China mountain inversion phenomenon prevails. In the Bailongjiang dry-hot valley, the inversion layer in winter from January to February appears at a relative altitude of 50 ~ 200m from the bottom of the river valley. The inversion with temperature below 15 0 m had the highest frequency with an average intensity of 0.5-1.0 ° C / 100 m and the strongest up to 3.1-4.0 ° C / 100 m. The results showed that under the conditions of artificial air humidity control, the effect of increasing production and increasing income of mushroom was obvious, and the amount of fruiting bodies at different height of inversion layer was significantly different , To 10 0m height of the largest amount of fruiting
