Culture methods and matters needing attention of imported Zhu Dinghong

Breeding method: the cultivation of Zhu Dinghong is suitable with crispy, permeable and acidic medium, before planting, the rotten and dry fibrous roots should be cut off, the healthy root system should be preserved, and the seed bulb should be properly watered. Disinfection is the key step in the cultivation of imported Zhu Dinghong, and must be disinfected with disinfectant in accordance with a certain proportion. Note: the basin soil should be replaced in 1-2 years, the fallen leaves and withered roots should be trimmed, and the prevention and control of diseases and insect pests should be done during planting.

I. Culture methods of imported Zhu Dinghong

1. Clean up the seed ball

(1) before planting, the rotten and dry bulb roots should be cut off, and the remaining healthy roots should be retained.

(2) if there are many layers of brown dry outer skin on the outside of the seed ball, it can peel off part of it and eliminate the hidden danger of ulceration to the maximum extent.

2. Planting balls to replenish water

(1) if the bulb loses a lot of water due to long-term storage, it is best to replenish the bulb properly, that is, soak the middle and lower part of the bulb with water slightly higher than the ambient temperature for 1-2 hours.

(2) if the planting experience is rich, some plant hormones such as gibberellin can be properly added to the water, which is beneficial to the rooting and expansion of the bulb in the later stage.

(3) however, attention should be paid to the concentration of gibberellin and the time of soaking, otherwise it will be self-defeating and cause damage to plant roots.

3. Disinfection

The main results are as follows: (1) Disinfection is the most important link in the cultivation of imported Zhu Dinghong. Generally, disinfectants such as carbendazim and chlorothalonil are used to disinfect according to a certain proportion.

(2) the disinfectant is used for irrigation after planting so as to achieve the purpose of disinfecting the soil.

4. Selection of media

The main results are as follows: (1) under the limited planting space, the choice of medium is very important. Zhu Dinghong is suitable for planting in a crispy, permeable and acidic medium.

(2) the recommended medium is peat: vermiculite: perlite = 2:1:1 or peat: perlite = 1:1. When it is inconvenient, ordinary sapropelic soil can be used instead of peat and river sand instead of perlite.

(3) it is best to mix 10% bone meal, calcium superphosphate and other base fertilizers in the medium.

5. Deep planting

(1) when the imported Zhu Dinghong bulb is first planted, more than half of the bulb should be exposed, and the status of the bulb should be checked frequently.

(2) the newly planted bulbs are very prone to fester. After this period of time, wait for the bulbs to grow out, and then cover the soil to 1/2 or 2/3 of the bulbs.

II. Matters needing attention in imported Zhu Dinghong culture

1. Pruning

Zhu Dinghong grows faster and its leaves are longer and denser, so it is necessary to cut off fallen leaves, withered roots, diseases and insect pests while changing pots and soil, leaving only exuberant leaves.

2. Replacement of basin soil

After 1 or 2 years of planting, the fertilizer in the basin soil will be very scarce. In order to promote the growth and flowering of Zhu Dinghong in the new year, it should be replaced with new soil in time.

3. Pest control

The main results are as follows: (1) in order to make imported red red grow vigorously and blossom as soon as possible, pest control should be carried out in time.

(2) anther should be sprayed once a month, and anther spraying should be done after 9 am or 4 pm on a sunny day. The sun is relatively strong at noon, so it is not suitable for spraying pesticides to avoid drug damage.
