What problems should be paid attention to in Yulong grass culture?

Yulong grass is a kind of herb for many years. What problems should be paid attention to in breeding Yulong grass? next, let's take a look at it together.

Yulongcao is a perennial herb of Liliaceae, with tuberous roots, well-developed roots, root length of more than 20 cm, milky white, few stems, short plants, clusters forming hemispherical clusters, about 10 cm high. Leaves simple, tufted, leaf blade 10-20 cm long, 0.2-0.3 cm wide, narrowly linear, leaf base sharp, leaf tip obtuse, leaf margin rough, dark green, upper and lower surface smooth, lower surface more or less powdery, veins 5-7. Racemes, 10 flowers per bud, flower stems erect, lavender to white. Capsule, ca. 0.5 cm in diameter, seed dark blue. This species is a dwarf variety along the step grass, and another white spot variety craze along the step grass, also known as the silver dragon, the leaves are 45-90 cm long, most of the white spots walk along the veins, and the leaves are hairy and not smooth. It can be propagated by the ramet method, and every 3 buds can be used as a unit. Because the root has nutrients and water, it can be stored in the shade for about a week if it is not planted immediately after the split. It grows and divides rapidly, and the planting ground can quickly grow into a thick felt-like turf, which has a particularly good effect on soil and water conservation. It has strong negative tolerance and is more resistant to trampling than ordinary turf, so it is an excellent place to be planted.

Morphological characteristics of Yulong grass

Rhizome

Yulong grass is a perennial herb, with tuberous roots, well-developed roots, root length of more than 20 cm, milky white slightly thick, almost stemless, short plants, clusters forming hemispheric clusters, about 10 cm high.

Leaf

Yulongcao simple leaf, tufted, leaf length 10 cm 20 cm, width 0.2 cm 0.3 cm, narrowly linear, leaf base sharp, leaf tip obtuse, leaf margin rough, dark green, upper and lower surface smooth, lower surface more or less powdery, veins 5-7.

Flowers

Yulong grass is a raceme, 10 flowers per bud, flower stem erect, lavender to white.

Fruit

The capsule of Polygonatum odoratum, about 0.5 cm in diameter, with dark blue seeds. Another variety of white spot craze along the steps, also known as silver dragon, leaves 45-90 cm long, there are most white spots along the veins of the leaves, the leaf surface is hairy and not smooth.

The flowering period of Yulong grass is from May to July.

Cultivation and management of Yulong grass

Yulong grass potted or planted on the ground is relatively simple and does not need fine management. But requires a well-ventilated semi-shady environment, often keep the soil moist, the northern dry season should often spray water, the leaves can be green and shiny, if the air is too dry, the leaves will often appear dry tip phenomenon.

It is not resistant to drought and is more resistant to water and moisture, but if the basin soil accumulates water for a long time, the plasma root and underground stem will also rot, because of its rapid growth, in addition to applying sufficient base fertilizer when planting, the growth period should also be topdressing, preferably once a month. Pay attention to the removal of weeds, pot growers should be placed in the shade in summer, avoid direct sunlight.

Yulong grass has green leaves in a shady environment. When planting in the ground, it should be planted in shady places and under trees. Potted plants should be placed in the shade to avoid direct sunlight. Yulongcao has strong cold tolerance and can survive in the open field and is evergreen in the south. In winter in the north, the temperature should be kept above 5 ℃, and the lowest temperature should not be lower than 1 ℃. Although the root system will not suffer frost damage at low temperature, the leaves will turn yellow.

Yulong grass should be protected by shade, and liquid fertilizer should be applied twice in June, but there is no need to topdressing in other seasons. The basin should be kept moist, and water should be sprayed frequently in the dry season in the north, so that the leaves can be oil-green and shiny. The soil should be planted with organic fertilizer, water thoroughly, and often remove weeds and irrigation to keep the soil moist and avoid drought. But not too much watering, especially in the flowering period, underground stems and fleshy roots will also rot.

The above is the introduction of Yulongcao culture, I hope it will be helpful to you.
