When the potted cultivation is carried out, the tubers are not buried in the sand bed to root, and then the roots are planted after the roots are grown. Not resistant to strong light, should be placed under the shade when planting, keep the pot soil moist during the growing season, and fertilize 1-2 times a month. In winter, it should be kept above 15 °C. If there is no heating condition, the tuber can be dug up and dried after the leaves are dry. The residual roots are accumulated in the sand layer and planted in spring. In order to germination neatly, the buds can be germinated first, and the tubers are arranged on a sand bed, covering 1 cm of fine sand, keeping the sand bed moist, and the room temperature is 20-22 ° C, and the plants are planted after germination and rooting. For example, the cue ball with larger tubers and more buds can be divided and propagated. The bud tuber is cut with a knife, and the sliced ​​surface is dried and healed before being potted.
In situ and batch breeding seedlings can be propagated by sowing and tissue culture. Sowing, seeding should be carried out immediately after seeding, and the seeds of the leaves are not resistant to storage, otherwise the germination rate will drop rapidly. At the seedling stage, the leaves are green, and when a certain number of leaves appear, the leaves begin to show colorful spots. Tissue culture, using MS medium plus 1 mg / liter of kinetin, 2,4-D induced callus, with MS medium plus 1.5 mg / liter of kinetin and 0.1 mg / liter of naphthalene acetic acid, from callus differentiation Adventitious buds were transferred to 1/2 MS medium plus 0.5 mg/L naphthalene acetate rooting medium. Explants can induce callus to form adventitious buds using young leaves, petioles and tubers. Using the tissue culture method, the flowering seedlings can be multiplied in a short time.
The ramets of the genus Corydalis are commonly used to breed. From April to May, before the tuber sprouts, the small tubers around the tuber are peeled off. If the tuber is injured, it is coated with grass ash or sulfur powder, and dried for several days until the wound is dry and potted.
Dividing tubers If the tubers are larger and the buds are larger, the nucleus can be segmented and propagated. The bud tuber is cut with a knife, and the sliced ​​surface is dried and healed before being potted. Whether it is divided or propagated or ramets, the room temperature should be kept above 20 °C, otherwise the planting tubers are susceptible to moisture and difficult to germinate, but cause rot and death.
Seeds are not resistant to storage due to the seeds of the colored leaves, sowing and breeding should be carried out immediately after the harvesting of the seeds of the colored leaves, otherwise the germination rate will be greatly reduced.
Tissue culture In 2000, the leaves or petioles were used as explant tissue culture, and the leaves or petiole could induce callus to form adventitious buds. By using the tissue culture method, the reproductive coefficient is large, and the offspring rarely mutate, and in a short time, the seedlings can be multiplied.
Hydroponics is a nutrient solution cultivation, which is divided into two methods: bulb hydroponics and petiole water insertion. It is a new technology that can make the leaves of the color leafhopper bright and reach the effect that the soil culture can not reach. Bulb hydroponics is cultivated when the temperature is stable above 22 °C in May. The bulbs can be directly planted in pots and cultured and rooted. It is also possible to first cultivate the sand, and then grow the new roots and then change to hydroponic culture.
Roots can be rooted in 7 to 10 days, and the roots are white. Petiole water can be used to breed colored leafhoppers during the growing season. When breeding, choose the mature leaves, peel off with the petiole, insert into the vessel containing the water, the depth of the petiole into the water is about 1/4 of the length of the petiole, change the water every other day, keep the water clean, about 1 The bulb can be formed in a month.
