Management skills of bonsai seedlings of Cymbidium

Seedlings refer to the bud seedlings in the growing period of about half a year, with about 1-3 leaves, the 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 itself, and the seedlings begin to divide into pots about 3 months after sowing, and the pots should be divided in batches at the right time. When the first leaf grows about 1cm, it is the best pot height, and the new leaves and seedlings without new leaves will be divided for the second time when they grow to a certain height.

When transplanting the seedlings in different pots, choose tools such as shallow pots or wooden boxes and plastic baskets, install the nutritious soil away from the upper 1cm, after leveling, use bamboo chopsticks or pointed bamboo sticks to make holes, open the spacing appropriately, then carefully insert the fleshy roots of the seedlings, and then press the soil, but note that the front of each leaf must be facing in one direction to facilitate daylighting.

Management of annual seedlings:

The seedlings of Cymbidium refer to the seedlings in the annual growth period, which usually have about 6 leaves. At this time, the characteristic of cultivation management is to divide the seedlings into pots and raise them, generally using 4-inch (13cm) flowerpots, which can be planted 1-3 plants according to the size of the place. The management of seedling stage directly affects the growth and development of plants. The temperature of the seedlings should be about 20 ℃, and attention should be paid to daylighting and ventilation. In the seedling stage, the number of roots is basically the same as the number of leaves. The pots planted by young seedlings with high temperature in summer are small and easy to dry. So when it is very hot, the seedlings should be watered in the morning and evening in order to maintain the humidity of the basin soil. After the seedlings are divided into pots, they can be fertilized, and the concentration of fertilization should be low, generally once every half month.

Management of two-year-old Zhonglan:

The two-year-old Chinese orchid is the two-year-old middle orchid stage from the seedling stage to two years old. At this time, it reached about 13 leaves, and the indexes of plant shape stability have been determined.

The management at this time is the main period of cultivation of Cymbidium, which has higher requirements on soil, moisture, temperature, light, fertilizer and so on. Two years born in spring and autumn need to change the nutrient soil, and change larger flowerpots, generally use 5-6-inch pots (16-20cm). When changing the soil, you should first fill the basin with a 5-thick nutrient soil, hold the root system by hand and enrich the soil to the core of the root system. Don't let the soil fall out and put it into the basin. It is filled with soil and compacted. The plant position is placed in the middle position, that is, do not expose the rhizome and do not bury it too deep. The correct position of the soil is buried between the rhizome and the pseudobulb.

Management of Cheng Ling Lan:

Gentleman orchid after more than two years of growth period, that is, into the reproductive growth stage, can blossom and bear fruit, that is, Chengling orchid.

After entering the reproductive growth period, Magnolia needs a large amount of nutrition supply. It not only grows and develops, but also arrows, blossoms and bears fruit. If the plant is malnourished, the plant will be weak, the flowering period will be delayed and the fruit will be set less. In order to make the orchid thrive, we must strengthen the management, pay special attention to the supply of fertilizer, apply potash fertilizer regularly, and increase the application amount of phosphorus and potash fertilizer. In order to ensure that the plant blossoms on schedule, the flowers are large and colorful, and the fruit setting rate is high.

When drawing arrows, Cheng Ling Orchid should maintain a suitable temperature and temperature difference and enough water to prevent the occurrence of arrow entrapment.
