China's oat producing areas can be divided into six regions, each with its own variety types, and the ecological types are obviously different:
1, an early-maturing ecotype of dryland in hilly and mountainous areas of North China
This ecological type is similar to the early-maturing ecological type in North China in many characters. The main difference is that the growth period is short, the plants are short, the grain filling speed is fast, and the 1000-grain weight is about 20g.
2. Early maturity ecotype in North China
The growth period of this ecological variety is about 90 days, with spring sowing (early April) and summer harvest (middle and late July). The seedlings are erect or semi-erect, with moderate tillering ability, short plants, few spikelets and florets, and 1000-grain weight 16-20g. Cold, drought and lodging resistance. There are many early-maturing and middle-late-maturing varieties.
3. Middle-late maturing ecotype in upland of northern China.
Ecological varieties have a long growth period, with summer sowing (mid-late May) and autumn harvest (late August to early September). Most of the seedlings are semi-prostrate or prostrate, with slow growth and strong tillering ability. In the rainy season (July), plants quickly jointing, rapid development, tall plants, soft stems, long and narrow leaves drooping. The seeds are large, with a 1000-grain weight of 22-25g.
4. Medium-mature ecotypes in north beach and Sichuan.
The growth period of this ecological variety is 85-95d, sowing in early summer (early and middle May) and harvesting in autumn (August). The plant is tall, the stem is tough and lodging-resistant.
5. Southwest Pingba Ecological Zone
It is mainly distributed in Pingba, the southwest plateau of China, with a growing period of 200-220d, sowing in autumn (10 10) and harvesting in summer (late May to early June) the following year. The growth and development of seedlings are slow, the creeping period is slightly shorter than that of southwest alpine ecotype, and the cold resistance is strong. The leaves are wide, the plants are tall and the stems are hard. The filling period is a little longer, and the 1000-grain weight is about 17g.
6. Southwest alpine ecotype
This ecological type is mainly distributed in the high mountain areas with an altitude of 2000-3000m in the southwest of China. The growth period is 220-240d, with autumn sowing (65438+1mid-late October) and summer harvest (mid-June to early July). The seedlings have long creeping period, strong tillering ability, slender leaves and strong cold resistance. The plant is tall, the stem is soft, and it is not resistant to lodging. The seeds are small, the 1000-grain weight is about 15g, and some varieties are less than 12g.

Oatmeal guide:
1, don't choose sweet products. This means that more than 50% of them are powdered sugar.
2. Don't choose products with delicate taste and insufficient viscosity, which shows that oatmeal content is not high and dextrin content is high.
3. Don't choose products containing creamer/non-creamer, because this ingredient is not good for health.
4. Aroma is brought by essence, not pure oats, so the fragrant products are not necessarily of good quality.
5, choose products that can see the unique shape of oatmeal, even fast food products, but also see the broken oatmeal.
6. If the package is opaque, pay attention to the protein content of the product. If it is less than 8%, the proportion of oatmeal is too low to be the only food for breakfast, and it must be eaten together with milk, eggs, bean products and other rich foods in protein.
