Cultivation method of orchid

Alias of blue: red, red. Pedicel has two opposite orchids, so it is called opposite orchids. The following is the related contents about the cultivation methods of opposite orchids that I have compiled for you, hoping to help you.

Cultivation techniques of orchid in sunshine

In the wild, Chinese cymbidium grows under the sunshine all year round, but if it is planted indoors, it is necessary to ensure its growth environment and let it have sunshine. If there is a lack of sunshine in your place of residence, put the orchids in a ventilated and dry environment and put them by the window.

land

The requirement for soil fertility is not high, but it is also necessary to ensure that orchids are not short of nutrients. After 1 or 2 years of planting, the nutrients in the basin soil will be lacking. In order to promote the growth and flowering of the new year, new soil should be replaced.

Factory division

Chinese cymbidium is cultivated mainly by small bulbs on the head. After 1 or 2 years of growth, many small bulbs will grow on the head. If the potted plants of Chinese cymbidium are small, it is very necessary to plant Chinese cymbidium separately. When changing pots and soil, you can divide plants, just like a child growing up on an orchid. After dividing plants, you can raise more orchids!

Fertilize soil or land

When changing pots, soil and planting, base fertilizer can be applied. Although the fertility of soil is not high for orchids, applying phosphorus and potassium fertilizer once a month can make orchids grow better, especially promote flower bud differentiation and flowering.

decrease

Cymbidium grows fast with long, narrow and thick leaves. When changing pots and soil, you can cut off dead leaves, roots and roots of diseases and pests, leaving strong and bright green leaves.

Orchids are propagated by sowing or separating small bulbs, that is, dividing bulbs, sowing or tissue culture.

Sowing propagation

Seeds can be sown when they are mature, and germinate quickly at 18℃-20℃. When transplanting seedlings, pay attention to prevent root damage. After the second transplanting, the seedlings can be put into a small pot. In winter, they must spend the winter in a cold bed or a low-temperature greenhouse, and change potted plants in the next spring, so that they can bloom in the third year. Generally, the method of separating small bulbs is used for propagation. The bulbs planted around the mother bulb can bloom in the next year if they are cultured separately.

Split sphere propagation

The ball-dividing propagation is carried out in March-April, and the balls around the mother ball are removed and planted separately. It is not advisable to cover the soil too much when planting, and it is advisable to expose the top of the small bulb slightly from the soil surface. It takes two years to reproduce in this way before it blooms. The ball-splitting propagation is usually carried out in July and August. First, cut the bulb into several pieces longitudinally, and then divide it into scales. The outer layer takes 2 scales as the unit, and the inner layer takes 3 scales as the unit, and each unit needs to have an eccentric disk. If the diameter of the divided bulb is greater than 6cm, each bulb can be divided into more than 20 double-scale and triple-scale cuttings. When the cuttings are obliquely inserted in the substrate (the ph value is preferably around 8), the temperature is kept at 25-28℃ and the air humidity is appropriate. After 30-40 days, 65,438+0-2 bulbs can be produced between the scales of each cuttings, and the base of each cuttings grows. Orchids are easy to bear fruit after artificial pollination. Seeds mature more than 60 days after pollination, and can be sown after maturity. After sowing, it germinates in the semi-cool place of 15- 18℃ and certain air humidity for about 15 days. Seedlings need to be maintained for 3-4 years before they can blossom.

Artificial pollination should be carried out to collect the seeds of orchids, which can improve the seed setting rate. Because the seeds of Cymbidium hybridum are flat, extremely thin, easy to lose water and lose germination ability, they should be planted immediately after collection. If bulbs are produced, the stems should be cut off in time after flowering to avoid consuming nutrients of bulbs. After the leaves grow, strengthen fertilization to promote bulb expansion and produce new bulbs. Bulbs can be stored at 13℃ for 8- 10 weeks and at 5℃ for a long time.

Scale cutting propagation

Select well-developed disease-free bulbs, peel off the over-ripe scales on the outer layer, and leave the middle scales with substantial growth for reproduction, but each scale must have a stem disk. In September, the scales were planted in a sand bed, and kept moist at 65438 08℃ ~ 20℃, then formed bulbs and took root at the base. The next spring, new seedlings grow on the small bulbs, which need to be cultivated for 3 years to become flowering bulbs.

Incision propagation

Select the seed ball with the circumference of 24-26 cm, soak it in 1% copper sulfate solution for 5 minutes, rinse it with water, cut off the seed ball of 1/3, gently cut off the main bud in the center of the seed ball with a knife, spread it on the sand bed, keep the room temperature at 18-22℃, and keep the air humidity at a high level.

Tissue culture and propagation

MS medium is commonly used, with stem disc, dormant bulb tissue, pedicel and ovary as explants. After tissue culture, callus was first produced, adventitious roots were formed after 30 days, and adventitious buds were formed after 3-4 months.

The growth habit of Cymbidium hybridum likes warm and humid Lanxi, and the suitable growth temperature is 18℃-25℃. Avoid extreme heat and strong sunlight, so it should be maintained under a cool shed. Afraid of floods.

The winter dormancy period of orchids requires a cool climate, which is 10℃- 12℃ and shall not be lower than 5℃. I like sandy loam rich in humus and well drained.
