Propagation and culture methods of blue flower mackerel

Blue vetch, a tree species introduced and cultivated in China in recent years, belongs to woody plants. It blossoms once a year in summer and autumn, with purple-blue flowers in full bloom, and is very elegant and beautiful, especially in the tropics. Blue-flowered trees are rare, so blue flowers are a rare and rare woody flower. So, how do blue flowers breed? What are the breeding methods of blue flower mackerel? Let's take a look at it.

The Propagation method of Scutellaria paniculata

The propagation methods of Carpinus przewalskii are divided into sowing propagation, cutting propagation and tissue culture propagation. The capsule matured in November, exposed or stacked in a windless place after harvest, dried and stored until March of the following year, and sowed when the temperature was around 20 ℃, but the seed germination rate was only about 5%. Cuttage propagation of Scutellaria paniculata can be carried out in both spring and autumn, and medium-mature branches are selected as cuttings with high rooting rate.

1. Sowing and reproduction

The fruit ripening period of the blueflower is in November. After picking, the fruit should be exposed to the sun or stacked in a windless place, dried and then stored, and sown in March of the following year. Because the blueflower is native to the tropics, sow seeds at a temperature of about 20 degrees.

2. Cuttage propagation

The cuttings can be propagated in both spring and autumn, and medium-ripe branches should be selected as cuttings when cutting, so that the rooting rate is high.

3. Tissue culture and propagation.

Tissue culture is also easy. Some scientific research institutions in China have used the stem top and stem segments of seedlings as explants to propagate a large number of test-tube plantlets.

The culture method of blue flower mackerel

1. Temperature and light

Blue flower is native to tropical America. It likes warm, humid, sunny environment and is not resistant to frost and snow. If you like the light, you can withstand the half-yin.

2. Soil and fertilization

For the fertile and moist sandy loam or loam, sufficient basal fertilizer should be applied when planting, topdressing once in spring and autumn after survival, pruning once in early spring every year, and heavy pruning should be applied to aging plants. When potted, it can be dried or grafted and dwarfed, and watering and nitrogen fertilizer can be controlled.

3. Pest control

The disease of blue flower is less, and the insect pests are mainly longicorn beetles. if reddish-brown dung shavings are found at the base of the trunk, a knife can be used to pick up the bark cortex to catch larvae; before the occurrence of adults, a mixture of 10 parts of quicklime, 1 part of sulfur and salt can be applied below 80 cm of the trunk to prevent adults from spawning.

Culture methods and matters needing attention of blue flower mackerel

Temperature

The blue flower is originally a kind of plant that grows in America, the growing environment is warm and humid, which determines that the nature of the blue flower likes the warm and humid environment.

The suitable growth temperature is 22 ℃ ~ 30 ℃. If the winter temperature is below 15 ℃, the growth will stagnate; if the temperature is lower than 3 ℃ ~ 5 ℃, there is a risk of frost damage, and the blue flower is not resistant to frost and snow, so remember to control the temperature in winter. The growth was also inhibited when the summer temperature was higher than 32 ℃.

Light

The blue flower is naturally fond of light, so it is best to put the blue flower in a sunny place, but the blue flower can withstand half-shade, and it should be properly shaded when the sun is too strong in summer.

Soil

Blue flowers like rich, moist sandy loam or loam, so you should pay attention to it when planting.

Fertilizer application

Pruning

Pruning is carried out once a year in early spring, and aged plants need to be re-pruned.
