How to cultivate smooth sailing (knowledge of smooth sailing maintenance of flowers)

Smooth sailing means beauty. I wish the college entrance examination students to ride the wind and waves and reach the other side of the ideal.

First, the general conservation methods of smooth sailing flowers

Smooth sailing flowers, also known as white crane taro, white palm and leaf taro, are perennial herbs. It is an important ornamental flower in the world, and also has the function of filtering indoor exhaust gas, which has certain effect on absorbing ammonia, acetone, benzene and formaldehyde, and is very suitable for family planting.

Smooth sailing flowers like high temperature, humidity and semi-cloudy environment, and can be placed indoors all year round. As long as there is bright scattered light, they can meet their own growth needs and avoid strong light. Generally, changing pots once a year requires loose soil and good drainage and air permeability, especially fertile loam rich in humus.

Second, the reason why the family is smooth sailing without flowering

1, do not change the pan all the year round

The smooth flowers grow rapidly, and after one year, the roots can grow all over the basin bottom, breathing is not smooth, and nutrients are exhausted, so they can't bloom. It is suggested to change the pots once a year, usually before a large number of new buds germinate in early spring every year. When changing pots, pay attention to clearing some soil, pruning roots and cutting off withered leaves.

The environment is too dark.

Smooth sailing flowers are resistant to shade, but if you don't see the sun for a long time, coupled with poor ventilation, smooth sailing will lead to malnutrition, thin leaves and dislike flowering. In winter greenhouse cultivation in the north, we must not shade or shade less.

3. Malnutrition

Smooth flowers bloom for a long time, and only with sufficient nutrients can they bloom more. Keep the soil moist during the growing period, apply fertilizer once every half month, and use thin compound fertilizer or rotten bean cake water. This is not only conducive to the robust growth of plants, but also conducive to continuous flowering. The winter temperature in the north is low, so fertilization should be stopped.

Third, the reasons for smooth sailing and flower withering.

1, improper lighting

Smooth flowers need better light in winter and early spring, so they should not be shaded. In summer, when the light is getting stronger and stronger, they should be gradually shaded and not directly exposed to the sun, otherwise they will be uncomfortable due to rapid changes in the environment, such as wilting, yellow leaves and even death.

2. Improper fertilization

Apply fertilizer thinly, don't apply thick fertilizer or raw fertilizer, and don't pour it on the leaves when applying fertilizer. If solid fertilizer is used, it needs to be watered with clear water, and it is best to use thin fertilizer water instead of clear water, so that it will generally not cause fertilizer damage and plants will grow vigorously.

3. The humidity is not suitable

Smooth sailing flowers have large leaves, are sensitive to humidity and need high growth humidity. When it is hot in summer or dry in autumn, it will cause leaf wilting, which can be solved by strengthening water spraying or sprinkling water to the surrounding environment to ensure that the air humidity is above 50%, which is beneficial to leaf growth. When dried at high temperature, the leaves tend to curl, become smaller, wither and fall off, and the flowering period is shortened.

4. Improper temperature

Smooth sailing flower is a high temperature variety and should be cultivated in high temperature greenhouse. The lowest temperature in winter should be 65438 06℃ at night, about 25℃ during the day, and the suitable temperature for growth is 22-28℃. If the temperature is lower than 10℃, the plant growth will be hindered and the leaves will be vulnerable to freezing injury.

5. Pests

If there are mites, the leaves will show wilting, lack of luster, yellowing and other adverse symptoms. It can be controlled by spraying acaricide (such as dicofol and pyridaben).

Fourth, prevention and control of smooth sailing flower diseases and insect pests.

When potted plants grow smooth flowers, if the environment is suitable and properly maintained, they will rarely suffer from pests and diseases. On the contrary, they may encounter some pests and diseases, such as red spider, scale insect, brown spot and leaf spot. These diseases and insect pests will lead to yellowing and deformity of smooth leaves.

1, Starscream

Red spider is one of the most prone diseases and insect pests. It is very small. It will hide on the back of the leaf and use its mouthparts to pierce the tissue to absorb the juice. The damaged leaves will shrink and wither due to malnutrition, and yellow and grayish yellow spots will appear.

Prevention and control: It is necessary to spray some drugs to treat the red spider, such as 10% tribenuron-methyl EC 1000 times solution. The prevention method is to pay attention to temperature control, because red spiders often appear at high temperature, and avoiding too high temperature can effectively prevent red spiders.

2. scale insects

Scale insects are also one of the pests and diseases of smooth sailing flowers. Its damage mode is similar to that of red spider, mainly sucking juice, which will not only lead to leaf withering and curling, but also cause soot disease and rapid reproduction. If it is not handled in time, the big branches and leaves will suffer.

Prevention: 50% chlorpheniramine 1000 times solution and 50% prochloraz 2000 times solution can be sprayed during the growth period to improve his disease resistance. Before planting, the soil should be kept free of germs, and the soil can be disinfected, such as soaking in formalin solution. In summer, we should avoid high temperature and high humidity.

3. Leaf spot disease

Leaf spot, also known as blight, is characterized by oval and long spots on leaves. At first, the color is light reddish brown, with faded circles around it, and then it will continue to expand into irregular shapes. In severe cases, black spots will appear in the spots, the leaves will be dry and dull, and then fall off.

Prevention and control: At the initial stage of the disease, spraying 50% thiophanate 1000 times solution, 70% mancozeb 500 times solution and 50% captan 500 times solution on the leaves can prevent the germs from invading other leaves. The prevention method is to pay attention to reasonable watering and fertilization when spraying drugs, and choose varieties with strong disease resistance when planting.

4. Brown spot disease

The main symptom is that the lower leaves suffer first. At first, the lesion was round or oval, and the color was purple-brown. In the later stage, it will continue to expand and connect multiple lesions, and the lesions will turn black. In severe cases, the leaves will fall ahead of time, which is the main reason for the smooth sailing.

Prevention: 50% chlorpheniramine 1000 times solution and 50% prochloraz 2000 times solution can be sprayed during the growth period to improve his disease resistance. Before planting, the soil should be kept free of germs and can be disinfected. For example, when soaking in formalin solution in summer, avoid high temperature and high humidity.

I hope smooth sailing will bring you the success of your career and all the prosperity! Flash moment, for your success.
