Culture method of Zhu Dinghong

Zhu Dinghong culture method is simple, in most cases casually buried in the soil will be able to flourish, and even forgotten in the corner of the light ball can tenaciously blossom, Zhu Dinghong culture is difficult, planting will often encounter seed ball fester, degradation, diseases and insect pests and other obstacles, especially into the □ ball planting, more careful treatment, otherwise, a brilliant flower may be a long silence. The following is a brief introduction to several key links of Zhu Dinghong planting:

-, Zhu Dinghong planting

Zhu Dinghong is suitable for growing at about 20-25 degrees Celsius, which can be used to determine the planting time. When planting potted plants at home, you can refer to the following steps:

(-) clean up the seed ball. Cut off the rotten and dry roots of the bulbs and retain the remaining healthy roots. If there are multiple layers of brown dry outer skin on the outside of the seed ball, part of it can be peeled off to minimize the hidden danger of festering.

Grow balls to replenish water. If the bulb loses more water due to a long storage period, it is best to replenish the bulb, that is, soak the middle and lower part of the bulb with water slightly higher than the ambient temperature for 1 or 2 hours, and those who have experience can add some plant hormones such as gibberellin to the water. Rooting and later bulb expansion, but we should pay attention to the concentration and soaking time, otherwise it will be self-defeating.

(3) disinfection. It is the key link of planting, and the common disinfectants such as carbendazim, chlorothalonil and methyl Topu can be used according to the instructions. After the end, the disinfectant water is used for irrigation after planting to achieve the purpose of disinfecting the soil.

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.

Today's content is here, the above is about Zhu Dinghong introduction, still hesitant friends can rest assured, hurry up to raise a pot! For more information, please follow the four Seasons Plant Network!

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.
