Plain sailing is a kind of perennial herb. Its flower stems are straight and beautiful, leaves are fresh and pleasing to the eye, and the bud of Buddha flame is white as snow. It is a very popular potted plant. So how is plain sailing? What good method is there in breeding? What matters should we pay attention to when breeding is going smoothly? Please read along with me with your questions^_^
Plain sailing (white crane taro) plain sailing breeding methods (basic knowledge): the best breeding time: plain sailing, in May to June for ramet propagation is better.
The best growing soil: the cultivation is smooth, which can be made up of Fuye soil or peat soil plus 1 / 3 of garden soil and a small amount of organic fertilizer, with good porosity, drainage and ventilation.
Growth humidity requirements: smooth sailing, sensitive to humidity. When it is hot in summer and dry in autumn, spray more water to ensure that the air humidity is more than 50%, which is conducive to the growth of leaves. When the temperature is high and dry, the leaves are easy to curl, become smaller, wither and fall off, and the flowering period is shortened.
The optimum growth temperature is 22-28 ℃, 24-30 ℃ from March to September, 18-21 ℃ from September to next March, and no less than 14 ℃ in winter. When the temperature is lower than 10 ℃, the plant growth is hindered and the leaves are vulnerable to freezing injury.
The best growth light: plain sailing, like warm and humid, semi overcast environment, avoid strong direct sunlight, not cold. In summer, 60% ～ 70% shade is needed, but it is not easy to blossom if there is insufficient light for a long time. 500 lux is appropriate.
Plain sailing flowering, farming plain sailing matters needing attention: spreading fertilizer: plain sailing fertilization to thin fertilizer application, do not apply thick fertilizer or raw fertilizer, and in the application of solid fertilizer after watering a clear water, it is best to use thin fertilizer instead of water irrigation, so that generally will not produce fertilizer harm, and plant growth luxuriant.
Watering requirements: plain sailing, generally watering once every 2 days, high temperature period should also spray water to the leaf and ground to improve air humidity.
Main points of propagation: plain sailing. There are two common propagation methods: ramet and sowing. Tissue culture can also be used for mass propagation.
Ramet propagation: because it is easy to sprout in plain sailing, this method is often used for propagation. The robust plants can be divided once every two years. The whole plant is poured out from the basin before the new buds are born in early spring, the old soil is removed, and the rhizome is cut at the base of the plant cluster. Each clump had better have more than 3 stems and buds, and should bring more root groups as much as possible, so as to facilitate the new plant to sprout new leaves and plump plant shape.
Sowing propagation: after the seed is mature, it should be harvested and sown at about 25 ℃ with low temperature, and the seed is easy to rot.
Basin soil replacement: plain sailing needs to be changed every 2 years. When changing the basin, remove part of the old soil, trim the root system, add new culture soil and plant it in the basin of No.1, so as to facilitate the root system development and growth.
Pest control: smooth sailing, if harmful mites harm, the leaves show wilting, gloss fading, yellow withering and other adverse symptoms, can be sprayed mite specific insecticides for control, such as dicofol, nisolone, pyridaben, etc.
Plain sailing is easy to grow, but the demand for magnesium is much higher than many other foliage plants. When the supply of magnesium is insufficient, the edge of smooth sailing old leaves will turn yellow. The growers should supplement the plants with magnesium by applying liquid fertilizer or solid fertilizer, or spray the plants with magnesium sulfate, magnesium nitrate or magnesium chelate regularly.
2. It is very important to control root rot. If the plant is infected with root rot, its root system will turn black, and cause the old leaves to wither, wither, and even cause the plant to die. There is no smooth sailing variety with good resistance to root rot in the market, so the best way is to focus on prevention. Spraying fungicides can prevent root rot, but can not cure the disease.
3. When gibberellic acid was sprayed to induce flowering, the flowering time varied with varieties. Generally speaking, the response of small varieties to gibberellic acid is relatively fast, and the flowering time is 7-9 weeks after spraying. It takes 10-11 weeks for medium varieties and 12-13 weeks for large varieties. It should be noted that high gibberellic acid concentration can cause flower deformation.
4. According to the variety, choose the appropriate size of the container. Some small varieties are suitable for planting in 4-inch containers, while some large varieties are suitable for planting in 21 inch containers. Growers should choose according to the actual situation.
