It is required that the winter is not too cold, and the summer time is 20°C to 25°C in the Yangtze River basin and South China. Regions are limited by climatic factors, and breeding is not easy. Generally, they are imported from foreign countries. They are cultivated in autumn and winter and bloom in spring. They are discarded after flowers are rejected. The bulbs are planted in advance and replanted for 30 days, which can promote early flowering. Basic cultivation methods Cultivation management methods using tulips and hyacinths. It is like a cool, moist and semi-negative environment, and its optimum temperature for fertility is 15°C to 20°C. It is relatively cold-resistant, can resist extreme cold temperatures of -10°C, and is resistant to hot heat, avoids rain and water, prefers well-drained, humus-rich sandy soil; it sleeps in the summer, and it grows roots shortly after planting in the autumn, followed by flowering from the anterior leaves to the following year. From April to May, the aboveground part withered. Breeding is mainly ball-breaking. Sowing can also be used. The ball can be carried out from August to September. Seeding can be done in May when the seeds are ripe and harvested, and then sowed in open beds or pots. Usually two years after cultivation, when the leaves are dry and the bulbs are over crowded, the bulbs can be planted and planted from seeding to flowering. 3 to 4 years. The land should be planted in a dry, sunny environment with well-drained, fertile sandy soil. Humus, loam, and acid yellow soil can also be planted; the planting period is generally from late August to early September, and no later than In late September. Planting spacing is generally 10 cm 15 cm, and the depth is 5 cm; the bottom of the cavities should be full of manure, mixed with manure, cake fertilizer and fire soil; in the flowering and final flowering stages, the compounding of the seedlings should be performed once again. Fertilizer, avoid excessive nitrogen fertilizer; to pay attention to sprouting due to too many shoots on the side of the parent bulbs, can be part of the removal of small buds, and do a good job of drainage work; leaves withered after the choice of flowers on sunny days to dig up bulbs, spread out in the shade for a week, Then graded storage. The potted plants can be planted from the end of September to October, with 5 to 6 full balls per pot, planted and placed outside, about 10 days after the roots are grown, transferred to a well-lit room, and maintained during growth. Wet soil, chasing thin fertilizer once every half; after flowering in late May, when the leaves are dry, the mature bulbs are removed from the pots, dried and placed in a cool and dry place, and left for the next planting.
