Usually exposed to the semi-exposed meat, actually sunburn, this situation may be more complicated, it may be because the residual moisture of the leaves become a concentrating mirror, the sun burned the meaty relationship. Also consider whether there is a spray, whether it has moved over the position (resulting in a disguised increase in light intensity). And the local weather changes, for example, the weather has finally dropped to 30 degrees, and in a few days back to 35 degrees, succulents may not be able to keep up with such changes, and then sunburned.
The new meaty newbie who just bought, feels that the flesh needs light, and it is autumn, and then it is sunbathing. Some of the meat that has just arrived at the green oil is particularly easy to sunburn and sunburn. The correct way to refer to the slow seedlings.
Reasons for raising bad meat
Glass block UV
Many people say that the reason why they do not raise the flesh in the room often puts the culprit on the glass because the glass blocks a lot of ultraviolet rays. How much UV light is blocked by the glass is controversial because the types of glass are not the same, and the wavelength of ultraviolet light is not the same. The figure below shows the transmittance of light at different wavelengths to the glass. BK7 is a commonly used ordinary glass. The ultraviolet light is divided into UVA, UVB, and UVC), and the wavelength ranges are 400-315 nm, 315-280 nm, 280-190 nm, respectively.
After the summer shady treatment, rashly increased the light, there was a sunburn, this is easy for everyone to understand, but also understand that just cannot be exposed to the sun in the fall, sunburn is a small matter, sun exposure is possible.
The exact amount of blocking is not necessarily an accurate value, but at least it can be known that UVA is basically not absorbed, and UVB absorbs most of it.
UVB is generally considered to be a synthesis of chlorophyll, carotenoids, and anti-UV pigments (these pigments are mainly phenolic compounds such as flavonoids, flavonols, anthocyanins, and elephant compounds such as carotenoids, resins, etc.) ) is influential, and the increase in blade thickness is also one of the positive effects against UVB. Therefore, raising meat through glass is really an effect on the beauty of flesh.
In addition to being absorbed by the glass most of the UVB, it is more likely that the reason for raising the flesh through the glass may be that your lighting time is not enough, because most of the flowers that are succulent through the window glass, the lighting time may be Not an hour or two.
And those who have glass greenhouses, bay windows, and the length of the light are close to the rooftops and balconies. It is difficult for you to see that they complain that the meat is not well fed. In fact, their fleshy state may not be as good as it is, but it is the easiest to raise. Ok, because the environment is stable, you don't have to worry about long-term rain and so on. The flesh has a more stable environment, grows, accumulates, and becomes beautiful.
Succulent glass flower room
The flesh is not well maintained through the glass, except that the glass blocks a part of the ultraviolet light (UVB), and because the light length of the glass is not enough.
In addition, it may be that the glass used is different. Different types of glass block UV rays. There are also glasses that do not block UV rays, such as quartz glass, borax glass, plexiglass, etc. Among them, quartz glass has the highest UV transmittance. Almost completely unblocked. There are also completely blocked UV rays. For example, the design of double glazing.
There are many people who buy more flesh in spring, and many of them are newcomers. And meaty likes lighting, and there are many people who know it, whether it is a novice or a veteran.
High temperature causes polyporous sunburn
Then there may be a problem, why the meat is only two or three days, and the meat is water, black, and different colors.
Because this spring is a bit annoying, in Xiamen, for example, in April, the highest temperature has been 30 °C for two consecutive days (the same period last year was 20 ° C, the last 30 ° C is after May), the slow seedling period directly exposed Raising, the light is too strong, it is easy to invade the infection, and then consider that some people may not root the roots before planting, and the problem is the probability event. More flesh is hi-light plant is right, but slow seedling period, as long as it is not long, as long as it does not fade, it is really less light, the better, once the temperature is 30 ° C, the air is bright and no direct light is the fleshy seedlings to settle down .
In addition to the seedlings that have just been bought, the seedlings should be planted indoors. If you plant them indoors during this time, you should also pay attention to slowing down the seedlings. You can't take all the sun all at once. The current plants are more delicate, full of sunshine, and light. Injury, the species is tan, water, and color.
The flowers have a faint smell of smoke. They were originally grown indoors and moved out for two days.
Also, the potting soil is too humid, the light is too strong, and the temperature is too high, it will easily cause some fleshy water of the sedum to fall into the leaves, especially the water retention of the garden soil and sandy soil is too strong and airtight. Water control and ventilation.
I just bought this soil and it is a garden soil. There is a problem. The soil is very easy to wet for a long time. It is easy for the accident at high temperatures.
In general, the temperature in the area of 30 °C in the near future should pay more attention to the fleshiness of the family. Some of the poor growth, such as the long-term dryness of the leaves, the excessive consumption of the leaves, the signs of falling leaves, can be properly covered. Yin, prepared for the summer. After the succulent plants treated in the summer, the scallops increased the light and appeared sunburn. This is easy for everyone to understand. They also understand that they can’t be exposed to the sun just in the fall. Sunburn is a trivial matter. It is possible to kill the sun.
