每年五到六月间,丁青县的山野刚刚返青时,期待已久的人们就已人手一把小挖镐,匍匐在海拔4000米以上的半雪半融的山岭草坡上挖虫草。但真正的冬虫,此刻才破土,刚长出3厘米左右深褐色的草尖尖。这时虫草有着最好的品质。错过这个时刻,虫草的草芽长得太长,冬虫的营养就会被消耗,再往后,雨季一来,虫草就会腐烂在泥土中。 From May to June every year, when the mountains and green fields of Dingqing County just returned to green, the long-awaited people have already found a small dig-and-dig and digged the weeds of grass on slopes of semi-snow semi-melting mountains above 4,000 meters above sea level. But the real winter insects, only at this moment ground, just grow about 3 centimeters dark brown grass pointed. At this time Cordyceps has the best quality. Miss this moment, Cordyceps grass buds grow too long, winter worm nutrition will be consumed, and then later, the rainy season, Cordyceps will rot in the soil.
