1, the difference of morphological characteristics
The plant height of Elymus nutans is much shorter than that of Elymus sibiricus, and the height of Elymus nutans is about 50-70 cm. Laomangmai 60-90 cm. When it comes to the color of the flower spike, the old awn is gray-green or lavender, and the elymus nutans is green, and it turns purple completely when it matures. In fact, the stems of the two are also different. Old awn wheat is mainly pink, and Elymus nutans is a common turquoise color.
2. Differences in living habits
The differences in morphological characteristics are mainly plant height and color, and then look at the differences in living habits. Elymus sibiricus will generally grow or be planted on the roadside for greening, and a small part will also be planted on the hillside to prevent wind, fix sand and conserve water. After all, the ability of old awn wheat to resist sandstorm and saline-alkali is still very strong.
Step 3 distribute
Elymus nutans is widely distributed, because its plants have no fine hair, no peculiar smell and good taste, so it is extremely used for raising cattle, sheep and natural pasture. Therefore, Elymus nutans can be seen in grassland, farm, hillside and woodland, but grassland is the most densely distributed. Elymus nutans, like Elymus nutans, has developed roots. The longer the drought period, the more developed the root system, even reaching about 1 m.
4. The ability to resist drought, cold and sandstorm is also first-class.
Although there are many differences between the two, there are also many similarities, not just the similarities in appearance you see. Both Elymus sibiricus and Elymus nutans are relatively drought-resistant, and their ability to resist cold and sandstorm is also first-class. Most importantly, their buds are as resistant to cold as ordinary buds. Even at MINUS 4-6 degrees Celsius, the buds can still survive normally, which ensures the survival rate to a great extent. Elymus nutans is often mixed with Poa pratensis and other herbs to build lawns, so there are still many choices for collocation, and the old awn wheat is single when planted. But each has its own advantages, let's look at personal needs.
