Different in appearance: Avena sativa culms are about 70cm in height, with 2-3 nodes, inflorescence spikelet stalks are slightly curved, spikelets probably have 3-6 flowers, lemmas are herbaceous and soft. After the fruit has grown to maturity, the lemmas are easily separated from the fruit and the yield is high. Avena sativa looks a little greenish and blackish, but this is normal. Oats are a little taller, with culms around 90cm tall, with 2-4 nodes, the spikelet stalks of the inflorescence are not curved, the spikelets have about 1-2 flowers, and the lemma herbaceous texture is very hard. The fruits are not easily separated from the lemmas after growth and maturity, and the yield is low. Oats, on the other hand, look clean, with a white-yellow surface.
Seed appearance is different: Avena sativa grows to maturity, its seeds are directly exposed to the outside, because it is also called "naked oats". Oats, on the other hand, have a layer of lemma wrapped around the seeds after they have fully matured.
Distribution areas are different: Avena sativa is usually distributed in the northwest, southwest and north China and other regions, in the hillside roadside, alpine meadows, and wet location of the wild distribution. Oat distribution will be more extensive, in most parts of China and other countries to have planted.
Second, the habits of oat and oatAvena sativa during the growth period, for moisture, temperature is very sensitive, during the growth period to control the water supplement. Its root growth is very developed, there is a strong ability to absorb fertilizer, to give it adequate fertilizer, not partial application of nitrogen fertilizer, if the lack of phosphorus and potash fertilizer, the plant is easy to collapse, the seed line state is also very poor.
Oats belong to the world's cultivated crops, it likes cool and moist environment, sun-loving, do not tolerate high temperature, in the growth of the period to be sufficient light, the lack of light, it will grow poorly.
