近年来,在我国青海高原上,出现了一种新型的小麦——豌豆麦。它的全生育期为95—100天,不仅比一般小麦品种(如阿勃等)早熟半个月左右,而且比生长期很短的青稞品种(如昆仑3号)还早熟1—2天。这样,就使得原来只能种植青稞的地区,也能种上了小麦,使青海高寒山区的春小麦生长线由海拔2700米左右,提高到3200米左右。在无霜期较长的地区,为了提高复种指 In recent years, a new type of wheat, pea and wheat has appeared on the Qinghai Plateau in our country. Its full growth period of 95-100 days, not only than the general wheat varieties (such as Abel, etc.) about half a month, but also shorter than the growing season of barley varieties (such as Kunlun 3) also precocious 1-2 days. In this way, the original area where only barley was planted could be planted with wheat so that the spring wheat growing line in the alpine mountainous area of ​​Qinghai would be raised from about 2,700 meters above sea level to about 3,200 meters. In areas where frost-free period is longer, in order to improve cropping
