How to raise Rhizoma Rehmanniae Culture methods and matters needing attention

Curly Dan is a kind of plant with high ornamental value. Its main ornamental point lies in its flowers, which are usually yellow. There are some spots on them, and some petals are curly, which is very special. At present, Curly Dan is very popular with consumers on the market, and many people like to breed it, but there are also some skills in breeding.

How to raise Curly Dan

1. Soil selection. Curl Dan likes fertile, humus-rich soil, requires good drainage, soil acidity is the best. Rotten leaf soil, garden soil and sandy soil can be mixed to make soil. when potted, in addition to the configured medium, you can also put rotten fertilizer or bone meal as base fertilizer. Before the soil is put on the basin, it needs to be sterilized.

2. Light. Light is a necessary condition for the growth of Solanum lanceolata. Only with reasonable light can it grow well, and the flowers bloom brightly, which does not affect the ornamental. Solanum lanceolata needs sufficient light, and insufficient light will make the plant grow poorly. In general, the light conditions in spring and autumn can meet the growth of lilac, but artificial light is needed in winter when the sunshine time is short. When it is hot and sunny in summer, to avoid direct sunlight, you can use a shade net to shade.

3. Temperature. Temperature control is also very important. Curly Dan likes a warm environment, and the suitable temperature for growth is between 16 ℃ and 28 ℃. It is afraid of high temperature but more hardy, but the winter temperature should not be lower than 2 ℃.

Culture methods and matters needing attention of Curtis chinensis

1. Culture methods:

1. Curly Dan likes to be dry and afraid of dampness, and watering should be appropriate. Generally, you can keep the basin soil moist, but when the growth is booming and when it is relatively dry, it needs to be watered more. When the air is too dry, it is often necessary to spray water around the plant to increase the air humidity.

The requirement of fertilizer is not high, so it is necessary to supplement nutrients in the growing period to ensure growth, and appropriate fertilization in the early stage of flowering to ensure the quality of flowering. During the growth period, it can be dilute liquid fertilizer for 2-3 times, and at the initial stage of flowering, it can be some phosphate and potash fertilizer, 1-2 times.

2. points for attention:

In order to make the curly Dan grow better, the basin needs to be changed once a year and replaced with new soil, which can be in October. And should often turn the flowerpot during the growth period to avoid the length deviation.

What should I do if the leaves turn yellow?

1. Control the growth temperature. How to control the growth temperature? don't worry, when it is hot and hot, you only need to move it to a well-ventilated and cool place to avoid strong light. The leaves will gradually return to normal.

2. Pay attention to the selection of watering and soil. When planting lilac, we must choose acidic soil to ensure the nutrition needed for growth, and we should irrigate alum and fertile water during the growth period. In this way, the leaves will not turn yellow because of lack of iron.

3. Fertilize according to the amount on time. If you apply too much fertilizer, you can try to change the water to lose the excess fertilizer, or pour the basin immediately and rinse the bulb root with clean water. If the leaves turn yellow because they have not been fertilized for a long time, you can use the new culture water to apply rarefied liquid fertilizer or compound flower fertilizer. In this way, you can save the yellow leaves and grow again.

Common diseases and their prevention and cure of Ludan

1. Penicilliosis. Control method: store the seed ball at the recommended lowest temperature, do not plant those bulbs whose base plate has been violated, and soak the susceptible bulb with 1/1000 carbendan, chlorothalonil, carbendazim and other fungicides for 30 minutes before planting. Then colonize. After planting, maintain the appropriate soil temperature.

2. Phytophthora. Prevention and control methods: disinfect infected soil with general soil disinfectants; use fungicides to control Pythium during cultivation can also effectively control foot rot; ensure that the soil has good drainage conditions; prevent crops from being moist for a long time after watering: the soil temperature should be as low as possible in summer.

The breeding method of Curly Dan is actually very simple, and we can start with its growth habits. In breeding, we should timely do a good job in the proportion of soil, and then do a good job in temperature control. In the later stage, we also need to strengthen the management of diseases and fertilizer and water, so as to ensure the growth of Lundan.
