The Culture method of Cymbidium

February orchid, also known as Zhuge vegetable. Biennial herbs of Cruciferae. It is native to North and Northeast China.

Morphological characteristics, plant height is 40cm to 60cm. The stem is smooth, covered with white powder, the basal leaves are nearly round, the middle leaves are pinnately divided, and the apical leaves are triangular-ovate and serrated. Racemes, flowers small, petals Obovate, with long claws, flowers blue or white, but also blue and white. Seeds small, rounded.

The growth habit of February orchid is strong, cold-tolerant, barren and lax, but the fertile loam with good drainage is better. Like light, more resistant to yin. It blossoms in late February.

The method of reproduction is sown and propagated, and the direct seeding is made from September to October in autumn. often after one sowing, it can grow and reproduce every year, forming a whole natural flower group.

Cultivation and maintenance at seedling stage, pay attention to watering and maintenance, remove weeds. After growing up, the seedlings have strong stress resistance, and the remains can be removed and destroyed after flowering and seed cracking.

Disease and insect pest control February orchid growth is robust, and the florescence is very early, so even if there is the occurrence of powdery butterfly larvae, it does not hinder its growth and ornamental, extensive maintenance.

Gardening is often used as a natural flower to decorate the corner of the courtyard.

Key points of February orchid planting method, points for attention in February orchid planting

February orchid has strong cold resistance and is evergreen in winter. Also more shade-resistant, used as ground cover, the covering effect is good, the chlorophyll is lush, a piece of green, make people like. It has strong adaptability and can grow from Northeast and North China to East and Central China. In case of heavy frost and snow in winter, although some leaves will be frozen, they can still sprout, blossom and bear fruit in early spring. It is not strict with the soil.

February orchid has strong vitality and strong adaptability to the northern environment, especially in winter, it has a strong ability of cold tolerance in northern winter. February orchid especially like the dark and humid growth environment for water, light requirements are not high, in the soil is suitable to grow in slightly alkaline soil. It is a kind of evergreen plant that is evergreen all the year round. It blossoms first in early spring and means to report spring. It is a very simple and lovely plant.

Planting method of February orchid 1. Planting method

Pueraria lobata is mainly propagated by seeds with strong regeneration ability, and the newly fallen seeds will germinate and grow new seedlings soon after withering: in the soil without ploughing, the artificially sown seeds can also grow seedlings and have a strong ability to resist weeds. Therefore, cultivation and management can be relatively extensive and easy. Some of the fresh seeds just harvested have the physiological phenomenon of post-ripening, the germination rate of early sowing is low, and the shade lasts for 1-2 months or even longer. The sowing time can be in summer or autumn, but August to September is the most suitable. There are 300 seeds per gram, and the sowing amount is about 1 kg per mu. If calculated according to each square meter, it should be 1: 2 grams per square meter. If spray seeding is adopted, it is best to increase the amount per unit area by 1020%.

2. Pot planting method

Mix the basin soil with garden soil, perlite and plant ash at 6:2:1, apply sufficient basic fertilizer when potting, and move the basin to a sunny place for routine fertilizer and water management.

3. Cultivation and management

Compared with other flowers, cultivation management is relatively extensive and does not need more maintenance. Cold tolerance, negative tolerance is strong, with a certain amount of scattered light, it can grow normally, blossom and bear fruit. It is not strict with the soil. It is best to choose sandy soil that is loose, fertile and well drained. As long as timely watering, fertilization, a little management can grow healthily. Fertilize 4 times a year. Flower bud fertilizer in early spring, strong fertilizer after flower fade, strong fruit fertilizer after fruit setting, strong seedling fertilizer before winter. If 0.2% potassium dihydrogen phosphate solution is sprayed once at the flower bud stage and the young fruit stage, the flower color will be more beautiful and the fruit will be fuller. Florescence is from early spring to June. The pod is long-striped and ripe in June. Seeds dark brown, ovate. Zhuge cabbage has lush green leaves in winter and early spring flowers bloom. In case of heavy frost in winter, it is necessary to strengthen frost prevention measures. In order to eat, ramets should be carried out frequently to promote the germination of tender stems and leaves.

Matters needing attention in planting orchids in February

1. Soil: February orchid is not strict with soil. It is best to choose sandy soil that is loose, fertile and well drained. Potted February orchid has higher requirements for basin soil. Here, it can be considered to choose 6 parts of garden soil, 2 parts of perlite and 1 part of plant ash to mix evenly, and the base fertilizer in the basin should be enough.

2. Lighting: as February orchid is a short-day plant, daily sunshine does not need too long, indoor light can be illuminated by scattered light.

3. Temperature: due to the cold resistance of February orchid, the temperature control can be extensive, and the most suitable temperature for growth and flowering is between 15 and 25 degrees.

4. Fertilization: orchid likes fertilizer in February. Sufficient fertility will not only make February orchid grow faster, but also promote the flowering and fruiting of February orchid to fertilize four times a year. Flower bud fertilizer in early spring, strong fertilizer after flower fade, strong fruit fertilizer after fruit setting, strong seedling fertilizer before winter. If 0.2% potassium dihydrogen phosphate solution is sprayed once at the flower bud stage and the young fruit stage, the flower color will be more beautiful and the fruit will be fuller.

5. Pruning: in order to maintain a good ornamental effect of the wildflower combination in the landscape layout, it must be controlled not to make it sturdy, and it is generally trimmed to the height of 10-15cm with a lawn mower during the fruiting period. In addition, when preparing land for autumn sowing, it is necessary to remove ground debris that hinder better contact between seeds and soil, including litter. At present, in the field of landscaping, it is the direction of future development to create natural and diverse landscapes, explore plant application forms that return to nature and return to nature, and build an economical and sustainable ecological environment. The combination of wild flowers can create a natural and beautiful landscape effect, and it has the characteristics of extensive management, rich species, wild interest, low cost and long viewing period, so it will become the most unique element in the field of landscaping and will be widely used.

Sowing points for attention: sowing time can be in summer or autumn, but August to September is the most suitable. There are 300 seeds per gram, and the sowing amount is about 1 kg per mu. If calculated according to each square meter, it should be 1: 2 grams per square meter. If spray seeding is adopted, it is best to increase the amount per unit area by 1020%.

6. Insect diseases: the common pests in February orchid planting are aphids, cabbage insects, snails, leaf miners and so on. If pests are found, drug control should be carried out in time.

Symptoms: in the early stage of the disease, yellow-green, polygonal spots appear on the leaf surface. Subsequently, a white downy mildew layer is produced on the back of the spot, causing swelling, bending and green petals on the stems and flowers.

B, pathogen: the pathogen is a fungus of downy mildew. The disease mostly occurred on the lower leaves of Orchid in February. Especially in April, the weather is cold and humid, and the plant is more susceptible to disease. Planting too densely can also lead to the disease.

C, diagnosis and countermeasures: select ventilated and transparent areas for planting. The planting density is reasonable. Spray 50% Phytophthora 500 times.

7. Weed management

Watering before sowing promotes the germination of weed seeds in the topsoil layer, which can germinate within two weeks if the soil moisture is moderate. Do not plough the soil again, or you will bring more weed seeds to the topsoil. Herbicide spraying can basically eradicate weeds, but be sure to rest for a period of time before sowing, because herbicides have a killing effect on any plant.

When using chemical herbicides, we must pay attention to safety and avoid chemical residues affecting the germination and growth of flower seeds, so the seeds of general wild flower combinations should be reserved for 3-4 weeks of recovery period in the soil before sowing, and then plant wild flower combinations, because the widespread use of herbicides may lead to the delay of seed germination or the weakening of flower seedling growth.

Remove weeds in time during flower seed germination so as not to spread. If conditions permit, weeds should be pulled up as soon as they are found. In addition, a more effective way is to use broad-spectrum herbicide or cut it off with a lawnmower (or irrigation cutter). Be sure to get rid of the weeds before they drop their seeds. Many annual or perennial weeds can be controlled with professional herbicides. These herbicides do not affect the growth and development of broad-leaved plants and can be used in wild flower combinations. They can be sprayed very well on new seedlings.
