2. Select seedlings after five leaves. In jargon, five leaves are dominant and seedlings grow to five leaves. All indicators are basically finalized, and the change will not be too big, which is the best stage for seedling selection.
3, the flower falls into shape, and the three arrows are conclusive. When buying Clivia, you should know that a gentleman orchid has to go through three times before you can draw a conclusion. Generally, the first arrow of Clivia changes little, and the second or third arrow changes greatly. The original plant type is quite good, and it is common to get worse after three arrows.
4. In addition, it depends on the offspring. The offspring are not good. It is not dispensable to stay in a good Clivia, but it can be raised and played.
Clivia has a unique technique for raising seedlings. The seedling raising time of Clivia is generally 1 1 to February of the following year. The key to raising seedlings is temperature control. Seedling temperature is generally between 20-30℃, with a certain temperature difference. In this way, rapid and even germination can be ensured.
Methods of raising seedlings in Clivia bonsai Before raising seedlings, prepare the utensils for raising seedlings, such as shallow pots, wooden cases and small plastic baskets. These appliances must have drainage holes or gaps. The size of the appliance is convenient to move, and the depth is about 8- 10cm. The following are several feasible seedling raising methods.
River sand seedling method:
Sieve the river sand to the size of small grains of rice, wash it with clear water, and then boil or scald it in boiling water for 3-5 minutes to eliminate harmful bacteria. Then put the treated river sand into a container, scrape it flat with a plate, and arrange the bud eyes of the seeds neatly downward. The spacing depends on the number of seeds. Seeds can be denser and seeds can be less sparse. Cover it with a layer of sand, just to cover the seeds, not too thick. After being covered with sand, it is about 1cm from the top of the appliance. Then water it, and then water it once a day for about 30 days, and the coleoptile will grow out.
Sawdust seedling method:
Sawdust seedling is cleaned with sawdust of white pine, forged wood or hard miscellaneous wood, put in a vessel, spread flat, spaced, covered and watered in the same way as river sand seedling method, except that sawdust seedling method is about a week earlier than river sand seedling method.
Pine needle seedling method:
Select larch pine needles, soak them to make them contain water, clean them, put them into utensils, flatten them, and put the seed buds inside. Different from the above two seedling raising methods, the covering layer on the seeds is thick, generally covering about 1cm. Pine needle seedling method has high emergence rate and is not easy to rot. Pine needles should be kept dry and wet.
Seedling refers to the bud with a growth period of about half a year, with about 1-3 leaves. Seedlings like light and high temperature, and the temperature can be controlled at 20-30℃. When the seed grows the first true leaf from the coleoptile, the plant begins to develop on its own, and the seedlings begin to be divided into pots about 3 months after sowing, and should be divided into pots in batches at the right time. When the first leaf grows to about 1cm, it is the best pot-dividing height. When the newly grown leaves and seedlings without new leaves grow to a certain height, the second pot-dividing is carried out.
The management skills of potted Clivia seedlings are as follows: using shallow pots or wooden boxes, plastic baskets and other devices, placing nutrient soil at a distance of 1cm from the upper end, leveling, punching holes with bamboo chopsticks or pointed bamboo sticks, properly spacing, carefully inserting the fleshy roots of seedlings, and then compacting the soil, but paying attention to the fact that the front of each leaf must face in one direction to facilitate lighting.
Management of annual seedlings;
Clivia seedlings refer to the annual seedlings, usually with about 6 leaves. At this time, the cultivation management is characterized by multi-seedling potted plants, generally using 4-inch (13cm) flowerpots, and planting 1-3 plants according to local conditions. Seedling management directly affects the growth and development of plants. The temperature of seedlings should be around 20℃, and attention should be paid to lighting and ventilation. At seedling stage, the number of roots is basically the same as that of leaves. In summer, the temperature is high, and the pots of seedlings are small and easy to dry out. Therefore, when the seedlings are particularly hot, water them once in the morning and once in the evening to keep the soil moisture. Seedlings can be fertilized after being divided into pots, and the fertilization concentration should be low, usually once every half month.
Management of biennial cymbidium;
Clivia is a biennial medium orchid from seedling stage to two years. At this time, it reached about 13 leaves, and all indicators of plant shape stability were qualitative.
At this time, the management is the main period of Clivia cultivation, which requires high soil, moisture, temperature, light and fertilizer. Biennial plants in spring and autumn need to change their nutrient soil and bigger flowerpots, generally using 5 -6 inch pots (16-20cm). When changing soil, you should first fill the basin with 1/5 thick nutrient soil, hold the root system by hand and enrich the root core. Don't let the soil fall out, put it in the pot. Fill the surrounding area with soil and compact it. Put the plants in the middle position, that is, don't expose the roots and don't bury them too deep. The soil in the right place is buried between the rhizome and pseudobulb.
Management of Cheng Linglan:
Clivia after more than two years of growth, that is, into the reproductive growth stage, can blossom and bear fruit, which is orchid.
Clivia needs a lot of nutrition supply after it enters the reproductive growth period. It should not only grow and develop, but also fly, blossom and bear fruit. If it is malnourished, the plant will be weak, with less flowering, delayed flowering and less fruit setting. In order to make Clivia grow sturdily, we must strengthen all kinds of management, especially pay attention to the supply of fertilizer, apply potassium fertilizer regularly and increase the application amount of phosphorus and potassium fertilizer. In order to ensure that the plants bloom as scheduled, the flowers are large, the colors are bright and the fruit setting rate is high.
