燕麦是一种古老的作物,在我国至少有几千年的栽培历史。类似于小麦中的一粒小麦、二粒小麦和普通小麦,燕麦也有二倍体(2n=2x=14)、四倍体(2n=4x=28)、和六倍体(2n=6x=42)三个种群。按其外稃性状可分成带稃型和裸粒型两大类,中国以种植大粒裸燕麦为主,俗称莜麦。虽说现今我国莜麦单产水平还没法与小麦相比,可是农业科技工作者对它却寄予厚望。有人甚至把它做为第二次绿色革命的主攻方向之一。
Oats are an ancient crop that has been cultivated for at least several millennia in our country. Similar to wheat, wheat and common wheat, oats also have diploid (2n = 2x = 14), tetraploid (2n = 4x = 28), and hexaploid Three populations. According to their nephew traits can be divided into two categories with 稃 type and naked type, China to grow large grain naked oats, commonly known as 莜 wheat. Although the current level of malting rice in China is still not comparable with wheat, agricultural scientists place high hopes for it. Some people even think of it as one of the main green revolution direction.
