Why are the flowers of osmanthus relatively small, and why are the leaves of potted osmanthus gettin

Because osmanthus does not bear much fruit It does not need too much accumulation of organic matter (sugars) Its stems and roots are also thin The leaves are larger, and after photosynthesis is improved, it will accumulate more sugars, which are easy to break or bend their own branches In addition, the main function of osmanthus is not to improve its own photosynthesis Osmanthus belongs to the cruciferous family This type of Chinese family The genotype controls the petals small and tender There are detailed explanations in plant morphology of the university.

Because its signature is fragrance, not flower petals.

Osmanthus, a lot of people will like it, there are many types of osmanthus, it is difficult to distinguish what variety of osmanthus is coming, osmanthus is relatively easy to maintain, it takes not much time, it takes too much time, but it is not good to raise osmanthus trees, there are some friends who raise the leaves of the osmanthus trees are getting smaller and smaller, the main reason is environmental factors, and the secondary reason is the reason for nutrients.

After all, the indoor potted osmanthus tree needs light, and the indoor maintenance must not be satisfied, the long-term lack of light will affect photosynthesis, and it will also grow poorly, and there may be many adverse effects in the end, and it is reasonable for the leaves to become smaller. If it is not minus dozens of degrees in winter, you can put it on the balcony outside, and if possible, try to bask as much as possible.

Osmanthus tree for nutrient demand is not large, in the normal maintenance process, twice a year fertilization, respectively, in spring and autumn, fertilization should be comprehensive, supplement sufficient nutrients, organic fertilizer plus balanced compound fertilizer plus trace element fertilizer. Foliar fertilizer can be supplemented in the medium term, or sprayed twice a month. Organic fertilizer should still be used a little more, and the nutrients of abrasive machine fertilizer cannot be replaced by other fertilizers.

Among the varieties of osmanthus, only the four seasons osmanthus can bloom many times, and the one you breed should be the four seasons osmanthus! The color of the four seasons osmanthus flowers is slightly white, or light yellow, the aroma is light, and the leaves are thin. It is a variant of the osmanthus genus Muxi.

The biggest difference with other varieties is that it blooms all year round, that is, it will bloom all year round, so the other name of the four seasons laurel is the moon laurel (in addition to the other name of the four seasons laurel, it is also one of the varieties of the four seasons laurel), but its floral fragrance is also the lightest among many osmanthus flowers, and the fragrance of the flowers can hardly be smelled.

It may be that you have osmanthus leaf blight. Osmanthus leaf blight is a plant disease that occurs on osmanthus leaves. The disease generally occurs in the leaf edge and tip of osmanthus leaves, which can dry up one-third to one-half of the whole leaf, and then make the whole leaf necrotic and fall off.

The disease is common in Hangzhou, Shanghai, Nanjing, Guangzhou, Changsha, Jinan, Fuzhou and other places.

Symptoms occur at the leaf margins and tips of the leaves. It begins as small light brown spots, then gradually expands into large, irregular patches, and if several lesions are connected, the whole leaf withers 1 3-1 2. The lesions are grayish-brown to reddish-brown, sometimes brittle, the edges are dark and slightly raised, and there are many small black spots scattered in the later part of the lesion, and the back of the lesion is lighter.

Horticultural control. Strengthen cultivation management. Potted osmanthus should avoid stagnant water, and increase the application of humus fertilizer and potassium fertilizer to improve disease resistance. Diseased plants should be removed in time, and diseased leaves should be removed in winter to feed the infected**.

Pharmaceutical prevention and control. During the onset of the disease, 1:2:100 times lime multiples of Bordeaux liquid can be sprayed in the initial stage, and then 1000-1500 times of 50% benzelat wettable powder, or 800-1000 times of 50% carbendazim can be sprayed for prevention and control.

In the season of high temperature and high humidity, it is necessary to spray regularly to prevent, and use 500 to 800 times of 75% wettable powder to have a good effect, once a week, 2 to 3 times in a row.

Once the disease is found, the diseased leaves should be removed in time, burned in a concentrated manner to reduce the source of infection, and sprayed 200 to 300 times of 25% carbendazim wettable powder, once every 7 to 10 days, until the disease is controlled.

How did the leaves of my osmanthus slowly dry up What is going on?

Different periods, different seasons and different nutrition, light, temperature, etc. determine the speed and size of osmanthus trees.

Osmanthus flowers bloom less? Don't panic, find these 5 reasons in time, and the flowers will be full of trees in the coming year.

It is because of the lack of sunlight and water, and the lack of nutrients, so the flowers bloom very small, and then it is necessary to give him proper watering and fertilization.

It is likely that the sun is not enough and the water is insufficient, and the nutrients are also very low, resulting in its flowers are very small, it is recommended to give it proper watering and proper fertilization.

This can be due to insufficient light or a lack of nutrients. We need to put it in a sunny place and also fertilize it.

Among the osmanthus, the silver osmanthus is the most fragrant, the golden osmanthus is the second, the four seasons of osmanthus is again, and the fragrance of osmanthus is the lightest. Osmanthus likes light, and when the light is seriously insufficient, it cannot bloom due to the weakening of photosynthesis and the accumulation of nutrients. Therefore, it is necessary to give sufficient light.

The osmanthus aroma includes 41 compounds such as -linalool, oxidized linalool, -cis-basilene, etc., and the amount of these compounds is greatly related to the amount of sunlight. Under the scorching sun, these compounds are easy to produce, so that osmanthus flowers will be fragrant under the sun's rays.

Because osmanthus contains a large amount of volatile and fragrant osmanthus oil, it is very fragrant. Generally, osmanthus oil can be extracted by fumigation.
