Breeding method of Zhu Dinghong

1: separate bulb reproduction

The old bulb can produce 2-3 small bulbs every year, which can be removed and planted. The ball takes about 2 years to blossom.

The propagation was carried out from March to April, and the balls around the mother ball were removed and planted separately, the soil should not be covered too much, be careful not to hurt the root of the bulb, and the top of the bulb should be slightly exposed to the soil surface.

2: reproduction by cutting method

Select the bulb with a circumference of 24cm and 26cm, soak the bulb in cupric sulfate solution for 5 minutes, rinse with water, cut off the main bud in the center of the bulb, gently cut the main bud in the center of the bulb with a knife, keep it flat on the sand bed, keep it at room temperature for 18 ℃, maintain a high air humidity, and form several bulbs between the scales after 2 months.

3: propagation by tissue culture

MS medium is commonly used, with stem disc, dormant bulb tissue, pedicel and ovary as explants. After tissue culture, calli were produced first, adventitious roots were formed after 30 days, and adventitious buds were formed after 3-4 months.

Culture method of Zhu Dinghong

Zhu Dinghong blossoms in April in spring and blossoms again in winter. Management should be strengthened as soon as possible to promote flowering. Fast growth, after 1 year of growth, should be replaced with adaptive flowerpots. The red pot soil of Zhu Ding has been planted for 1 or 2 years, and the basin soil is lack of fertilizer. In order to promote the growth and flowering of the new year, it should be replaced with new soil. The growth is fast, and there are many bulbs growing in the head after 1 or 2 years, so the plants are divided at the same time when changing the basin and soil, so the co-planting of large plants is one pot, that of middle plants is one pot, and that of small plants is one pot. The bottom fertilizer should be applied at the same time when changing the basin, changing the soil and planting, and the phosphorus and potassium fertilizer should be applied once a month after the pot is put on the pot. the principle of fertilization is thin application to promote flower bud differentiation and flowering. Zhu Dinghong grows vigorously and blossoms as soon as possible. Pest control should be carried out. Anthers should be sprayed once a month. Anthers should be sprayed around 9: 00 a.m. and 4: 00 p.m. on a sunny day, and should not be sprayed in the hot sun at noon to prevent drug damage.

Zhu Dinghong likes warm and humid climate, the suitable temperature for growth is about 23 ℃, avoid extreme heat, the sun should not be too strong, should be maintained under the shade. I'm afraid of flooding. During the dormant period in winter, a cool climate is required, which should be 11 ℃ and not less than 5 ℃. Like sandy loam rich in humus and well drained. The artificial cutting ball method is often used to propagate a large number of seed balls. That is, it is cultured by sowing, dividing balls, cutting bulbs, tissue culture and so on.

Breeding method of Zhu Dinghong

[FAQ] Zhu Dinghong, also known as safflower lotus, is a perennial herb native to Peru and is now commonly cultivated in Hainan and other provinces in China. Some people want to know what are the breeding methods of Zhu Dinghong. Let's take you to see the breeding methods of Zhu Dinghong.

[expert answers]

The main results are as follows: 1. Ball reproduction: ball reproduction is carried out from March to April, and the balls around the mother ball are removed and planted separately. The soil should not be covered too much and the top of the bulb should be slightly exposed to the soil surface. The propagation of this method takes 2 years to blossom.

2. The propagation of segmented bulb: the propagation of segmented bulb is generally carried out from July to August. First, the bulb is cut into several pieces longitudinally, and then it is divided according to the scales. the outer layer takes 2 scales as a unit and the inner layer takes 3 scales as a unit, each unit needs to have a partial bulb disc.

3. Scale cutting propagation: select well-developed disease-free bulbs, peel off the over-mature scales in the outer layer, and leave the middle scales with full growth for reproduction, but each scale must have a stem disk. In September, the scales were planted in a sand bed and kept moist at 18 ℃ ~ 20 ℃. In the same year, small bulbs were formed and roots took root at the base. New seedlings will grow on the bulbs in the next spring and need to be cultured for 3 years to become flowering bulbs.

4. Propagation by engraving method: select the bulb with a circumference of 24cm and 26cm, soak the bulb in 1% cupric sulfate solution for 5 minutes, rinse with water, cut off the bulb's 1hammer3, gently cut the main bud in the center of the bulb with a knife, lay flat on the sand bed, keep the bulb at room temperature for 18,22 ℃, maintain high air humidity, and form several small bulbs between the scales after 2 months.

5. Propagation by sowing method: because the seeds of Zhu Dinghong are flat, extremely thin, easy to lose water and lose their germinating power, they should be sowed immediately after seed collection. Such as bulb production, cut off the flower stem in time after flowering, so as not to consume the nutrients of the bulb. After the leaves grow, strengthen the fertilization to promote the bulb to enlarge and produce new bulbs. The bulb can be stored for 8 weeks at 13 ℃ and for a long time at 5 ℃.

[editor's summary]

Zhu Dinghong is a kind of ornamental flower widely cultivated all over the world. in addition to potted plants, it can also be cultivated in open courtyards. Zhu Dinghong has large flowers, strange flowers, many colors and simple maintenance, so it is a popular potted plant. In this article, the editor of the first Agricultural Classic has introduced to you several breeding methods of Zhu Dinghong, hoping to be helpful to you.
