How does the latest gentleman orchid grow up fast?

Magnolia is a noble, standing high-taste precious flower, also known as Lycoris, Lycoris, etc., is a perennial herb ornamental plant of Amaryllidaceae, native to southern South Africa, flowering for as long as 30 to 50 days, mainly in winter and spring, but New Year's Day also blossoms before and after the Spring Festival. Let's take a look at how the orchid grows quickly.

How does the gentleman orchid grow up fast?

1. Soil: Magnolia is suitable for acidic and corrosive soil with good air permeability, sufficient water but not too saturated, which can be mixed with 65% humus soil, 20% net sand and 15% fine furnace ash. Soil needs to be changed constantly in the process of growth.

2. Fertilization: the orchid should apply solid fertilizer once in winter, less nitrogen fertilizer, more phosphorus fertilizer and potassium fertilizer, and can also apply nitrogen, phosphorus and potassium compound fertilizer to promote its germination of more new plants and leaves, but fertilization must be appropriate. Do not apply thick fertilizer and raw fertilizer that has not been fermented.

3. Watering: the gentleman orchid can combine watering with fermented bean cake water, fresh fish water and horseshoe water every 20 days or so. Watering should be controlled when the room temperature is low to prevent the basin soil from being too wet, which will cause the death of the rotten roots of the plant, but it can not make the basin soil too dry.

4. Temperature: the suitable temperature for the growth of Cymbidium in winter is 15-20 ℃, which should not be lower than 10 ℃. The temperature should be kept at about 18 ℃ after scurrying, and the temperature difference between day and night should be about 10 ℃, otherwise the flower arrow will blossom if it does not reach a proper height, and it is easy to form a "sandwiched arrow".

5. Illumination: Cymbidium is a medium-light plant, in which scattered light is the best, and there is no need for strong light in the process of growth, especially in summer. In winter, strong light will shorten the flowering period, medium light can prolong the flowering period, and short-day treatment can be used if early flowering is needed.

Why don't magnolia blossom?

1. Nutritional discomfort: after entering the reproductive stage, Magnolia should supply some nutrients to the reproductive organs for flower bud differentiation, at this time, if more nitrogen fertilizer is used and there is a lack of phosphate fertilizer, it will cause the plant to grow so that the flower bud differentiation can not be carried out normally, thus affecting the normal flowering.

2. Water imbalance: the life activity of Cymbidium needs water, and the nutrients in the soil can only be absorbed by root hairs after being dissolved by water, so it should be watered reasonably to make the plant grow well. After entering the reproductive growth period, carry out normal flower bud differentiation and blossom in time.

3. Light discomfort: Cymbidium belongs to middle sunshine flowers, which can only grow but not differentiate flower buds under long sunshine conditions, so it can not blossom for a long time. In order to make orchids bloom, they must be moved to the room without lights at night. It doesn't matter when the scape is pulled out.

4. Temperature discomfort: Cymbidium stops growing when the temperature is lower than 10 ℃ or higher than 30 ℃. Too high or too low room temperature will lead to poor plant growth, and then affect the blooming of pregnant buds, so it is appropriate to cultivate Cymbidium at 11-17 ℃.

What should I do with the arrow in the gentleman's orchid?

1. Temperature discomfort: the suitable temperature for the growth of Cymbidium is 15 ~ 25 ℃, and when it is below 15 ℃, it will grow poorly, especially if it is less than 15 ℃ before coming out, the scape will be difficult to extract, so it is necessary to adjust the temperature in time to facilitate scape extraction.

2. The temperature difference is not enough: the growth habit of Cymbidium is preferred to have a large temperature difference between day and night, but it is difficult to extract scape if the temperature difference is small. After flower bud differentiation and before scurrying, the temperature should be controlled at about 10 ℃, so it is easier to shoot arrows, otherwise the phenomenon of arrow entrapment will occur.

3. Insufficient fertilization: after 3 years of cultivation, it is necessary to increase the times of fertilization in autumn. It is best to apply liquid fertilizer with high phosphorus content, and alternately apply nitrogen, phosphorus and potassium. If necessary, 0.2% potassium dihydrogen phosphate foliar fertilizer can be applied to promote flower bud formation and early flowering.

4. Improper watering: if the orchid is short of water, it will hinder the scape growth and lead to arrow entrapment, so it is necessary to increase the amount of water to keep the basin soil moist, otherwise the bulbs and leaves will hinder the physiological activities of the plant due to lack of water. so that the arrow clip affects flowering.

5. Excessive pressure: when Cymbidium is transferred to reproductive growth, we should always pay attention to the changes of the bulb. If the arrow is caught because of the excessive pressure on the bulb, the leaf sheath holding the scape can be cut open 1.5 cm with a sharp knife to reduce the pressure on the scape at the base of the leaf sheath and promote scape.

How to manage the gentleman orchid in winter?

1. Fertilization: Magnolia has the fastest vegetative growth in winter and needs the most nutrients, so it is very important to apply winter fertilizer well. Before entering the room, flowerpots are watered with bone powder, fried sesame, cooked soybeans or compound fertilizer every 15 to 20 days, and the roots can also be watered with soaking solution from animal and plant residues.

2. Watering: Cymbidium is fleshy root, good gas is afraid of water stains, leaves have waxy layer, low temperature in winter, less transpiration and evaporation of water. Therefore, watering should not be too much, as long as combined with fertilization watering, to keep the basin soil moist, must not be flooded, resulting in rotten roots and dead seedlings.

3. Heat preservation: Magnolia must keep warm and frost-proof in winter, and it is appropriate to maintain about 18 ℃ after the flower stem is pulled out. If the temperature is too high, the leaves and flower moss are only long and thin, the flowers are small and poor, and the florescence is short. The temperature is too low, the flower stem is short, easy to clip arrow preterm birth (flowering), affect the quality, reduce the ornamental value.

4, dimming: gentleman orchids like scattered light, avoid direct strong light, indoor maintenance in winter should be placed in a place with sufficient light, especially before flowering, there should be good light, which is beneficial to the development of buds. After flowering, proper cooling, avoiding strong light and keeping good ventilation are beneficial to prolong the flowering period.

5. Leaf protection: Cymbidium leaves have strong fat flowers, colorful chlorophyll flowers and short, broad, thick, green, bright and strong leaves, which are also the basis for promoting flowering and improving ornamental value. in addition to providing reasonable fertilizer and water, the leaves must be kept clean to improve photosynthetic efficiency.
