Where is Lubinghua suitable for planting?

Born in sandy soil, acidic sandy loam with deep soil layer, loose fertility and good drainage (ph value 5.5) is required, and the plant growth of neutral and slightly alkaline soil is poor.

When will Lubing blossom?

Under the natural conditions, it is best to sow in autumn, that is, from September to the middle of October, and the florescence is from April to June of the following year.

How do you plant Lubing flowers?

Planting Lubing flowers can generally be sown or cut. The specific planting methods are as follows:

Sowing and reproduction

Under natural conditions, autumn sowing blossoms earlier and grows better than spring sowing, so it is best to sow in autumn, and its seeds germinate neatly under the high temperature of 21-30 ℃. Of course, it can also be sown in spring, but the growing period after spring sowing in March is in summer, which may lead to non-flowering or low proportion of flowering plants, short spikes and poor ornamental effect due to the influence of high temperature and heat. Therefore, if there is no choice, it is best to sow seeds from September to mid-October so that they can blossom from April to June of the following year.

When sowing, 72 holes or 128 holes are sown and covered. Seedling soil should be loose and uniform, breathable and water conservation, special seedling soil or peat soil, perlite mixed use is better. Seeds larger, common or coated, about 40 / g. The optimum temperature for germination was about 25 ℃, and the medium was moist. The seeds were unearthed and germinated in 7 days and 10 days, and the germination rate was high.

2. Cuttage propagation

Cuttage propagation in spring cutting rhizome sprouting branches, cut into 8-10cm, preferably with some rhizome, cutting in the cold bed. In hot and rainy areas in summer, lupin can not die after summer, so it can be used for biennial cultivation. It is suitable to be planted in early spring, plant distance from 40cm, early planting, early flowering and seed setting. The aboveground part withered after fruiting before summer, and new plants germinated in autumn, or seeds were collected before withering. North China needs protection over the winter.

[tips]

Lu Binghua likes to be cool, sunny, hot and slightly shady. Deep-rooted, few nodules. It is required that the soil layer is deep, fertile and loose, good drainage, acid sandy soil (pH value 5.5), neutral and slightly alkaline soil plant growth is poor. The seedling stage of lupin is 30 to 35 days, and the seedlings are transferred and planted after the true leaves are fully unfolded. The root system of lupin is well developed, and the original soil is retained when transplanting seedlings, which is beneficial to slow down the seedlings.
