The temperature is too high in summer, what should I pay attention to when raising orchids?

Of all the flowers we maintain, there are flowers that bloom in the winter and flowers that bloom in the summer. Today, Taozi will talk about a kind of flower, which has a long history in our country and has a beautiful meaning. Flowers bloom in winter, today I will talk about how to manage summer summer, this flower is the orchid that many of us love.

First of all, we need to know the growth habits of orchids, what kind of growth environment they like, we will actively create such a growth environment to maintain, orchids like a cool growth environment, like to maintain in a place with good ventilation conditions, like semi-shade and scattered light conditions, like humidity of the air, do not like high temperature and strong light growth conditions and environment.

To maintain orchids in summer, Taozi believes that they can be managed and maintained from the following aspects.

The first is to take measures to block out bright sunlight. Orchids do not like high temperature in summer, so in the summer to maintain the orchid indoors, it is necessary to take measures to cool down to ensure a smooth summer, you can use a shade net to block the strong light, block 40% of the strong light, you can also move the orchid away from the strong light, put it in a cool place for maintenance.

Second, actively increase air humidity. The indoor temperature is higher in summer, generally the temperature will be above 25, such a temperature is not conducive to the growth of orchids, at this time, you can only often spray water around the orchid pot and leaves to increase the air humidity, and at the same time can also reduce the temperature, you can put a few more pots of water around the orchid, and you can also increase the air humidity to a certain extent.

Third, take cooling measures. The cooling measure taken is to place the orchid in the corner of the room, maintain a semi-shaded growth environment, and have a small amount of scattered light.

Fourth, keep the ventilation conditions good. Orchids like to grow in well-ventilated places, and orchids that are maintained indoors in summer can be placed on the north balcony and come to the window in time to keep the ventilation conditions good, or they can be placed in a wide outdoor place, which is more well ventilated. Of course, block out strong sunlight.

Fifth, prevent pests and diseases. Summer is the season of frequent pests and diseases, usually observe the leaves and planting materials of orchids, if you find that the leaves, or planting materials appear pests and diseases, you can take preventive measures in time, you can use carbendazim solution or dichlorvos to control diseases and insect pests.

Orchids prefer a cool place, try to put in the living room and often open the window for ventilation to ensure the circulation of indoor air, in addition to frequent watering, because the temperature is too high, water absorption and evaporation are relatively fast, watering every other day, but also frequent pruning of branches and leaves, so that the life cycle of orchids can be longer, and it is not easy to have yellow leaves.

Put them in a shady place, the plant should not be exposed to the sun, otherwise it will wilt their leaves, and water them to ensure that they are hydrated and make them grow more vigorously.

We need to water it and also put it in a backlit and ventilated place so that the orchid does not dry up. Apply beer evenly to the green leaves of the flowers, and the green leaves will be brighter.

Raising orchids, keeping in mind the influence of temperature on it, it is much easier to raise well.

The best way to maintain orchids in summer is to keep them ventilated, see light reasonably, and water them in the morning and evening.

1. Keep ventilation.

In summer, when the temperature is high and the weather is hot, orchids are prone to leaf spot disease, and brown spots will appear on the leaves, mostly because the environment is not suitable and the air circulation is not smooth. When encountering these phenomena, first open the window to ventilate and keep the air unobstructed, so that the roots of the orchid can breathe normally, and then spray the orchid leaves with sterilization and disinfectants.

2. Reasonable light.

Orchids that grow in nature are generally next to tall trees, with leaves blocking strong light, and if the sun is too strong and the temperature is too high, it will burn the leaves and burn the roots, so it can be seen that orchids cannot be directly exposed to the sun, and they need to be planted in a place of astigmatism.

3. Water in the morning and evening.

In summer, watering orchids should avoid the time period with the highest temperature, generally water once in the morning or at night, and choose soft soil, good ventilation and drainage. In summer, the temperature rises and the water evaporates quickly, so the pot should not be too dry; Long-term damp and stagnant water is not good, too much stagnant water, the roots can not breathe, which will lead to yellow leaves and rotten roots.

Sowing method of orchids

Orchids are commonly propagated by dividing plants, sowing jujube seeds and tissue culture. Orchid seeds are very fine, there is only one incomplete embryo in the seed, the germination power is very low, and the seed coat is not easy to absorb water, so it can not germinate by conventional sowing methods, so it is necessary to use orchid fungus or artificial culture stool mountain base to supply nutrients in order to germinate.

It is best to choose the fruit that has not yet cracked for sowing, after the surface is sterilized with 75% alcohol, take out the seeds, soak them in 10% sodium hypochlorite for 5-10 minutes, take them out and rinse them with sterile water 3 times to sow them in the culture flask containing the medium, and then put them in the dark culture room, keep the temperature at about 25, and then move them to the light after germination to form the original corm. From sowing to transplanting, it takes six months to a year. Tissue culture has been successful, and this method can be used to propagate where possible.

1. Shading and ventilation: Put the orchid in a semi-shaded and ventilated position to avoid direct sunlight. 2. Cooling and humidification

When the temperature is above 32 degrees Celsius, you can spray water mist around the plant or use air conditioning to cool it down. 3. Reasonable fertilization: Thin fertilizer should be applied to orchids in summer.

4. Precautions: Regularly clean up yellow leaves and diseased leaves to reduce the probability of disease.

1. Shade and ventilation

The light is very strong in summer, in the process of breeding orchids, we must properly shade and avoid being exposed to direct sunlight, use a shade net to block 60% of the light, and you can see the light before 9 am and after 5 pm every day, and the air is hot and dry in summer, so it is best to put the orchids in a ventilated place indoors.

2. Cooling and humidification

The best growth temperature of orchids is about 20-28 degrees Celsius, and the temperature in summer is usually higher than 32 degrees Celsius.

3. Reasonable fertilization

Although the summer is hot, it is the vigorous growth period of orchids, at this time the plant has a higher demand for nutrients, in order to ensure smooth growth, you can apply a thin compound fertilizer every 20 days, but in midsummer, the orchid enters a semi-dormant state, and it is necessary to spray foliar fertilizer.

4. Precautions

In the process of breeding, it is necessary to clean up the diseased leaves, yellow leaves, and dead leaves on the plants in time to avoid breeding bacteria, and to spray disinfectant water and insecticides regularly to reduce the incidence of disease.

The most important thing to raise orchids in summer is watering.

Reasonable watering methods can make the orchid itself better cope with the high temperature in summer, the temperature is high, the transpiration of water will also be strengthened, plus the planting of orchids is not the use of nutrient soil, but the use of materials, there will be gaps between the materials themselves, and the evaporation of water will be faster.

Once the orchid material is deprived of water, the root system of the orchid will wither, affecting the plant itself.
