What is the cultivation method of sweet-scented osmanthus? detailed explanation of sweet-scented osmanthus culture techniques

As the saying goes, Yangchun is rich in peaches and plums in March, and sweet-scented osmanthus in August. If someone in the house next door is hit by sweet-scented osmanthus, the fragrance can be smelled from afar when the sweet-scented osmanthus blossoms. So, what is the cultivation method of sweet-scented osmanthus? Detailed explanation of sweet-scented osmanthus culture technology.

Sweet-scented osmanthus blossoms, planted in the residential community or in front of the window, can let people enjoy the effect of "golden wind to send incense". Sweet-scented osmanthus can be processed into sweet-scented osmanthus cake, sweet-scented osmanthus wine and other food. Sweet-scented osmanthus is a small evergreen tree. The crown is oval, the branches and leaves are luxuriant, and the leaves are opposite, leathery and shiny. Flowers are yellow, white, orange, orange-red and other colors, with a strong fragrance. The seeds are black, flowering from September to October, and fruiting from April to May in the following year.

Here is the editor to introduce how to plant sweet-scented osmanthus.

1. Variety selection: the flowering time of different varieties of sweet-scented osmanthus is also different, such as laurel, four seasons osmanthus and so on are early flowering varieties, which bloom several times a year, and some varieties need a long vegetative growth period from seedling raising to flowering, such as Jin Gui, Yingui, Dangui and so on, which often take several years to bloom. Therefore, try to choose a short, handsome and strong early flower to plant.

two。 Preparation of basin soil: sweet-scented osmanthus likes to grow in slightly acidic soil rich in humus (PH value is 5.6-6). Do not grow with alkaline soil or clayey soil. 4 parts of humus can be used in culture soil. 3 parts of sand and 3 parts of mature barnyard manure were mixed with a small amount of fish scales, bone meal, etc., or mixed with 5 parts of mountain mud, 3 parts of rotten leaf soil and 2 parts of sand. In order to overcome the alkalinity of soil and water quality, during the growing period, 0.1%-0.2% ferrous sulfate solution is sprayed every half month or so to make its branches and leaves dark green, which is also beneficial to growth.

3. Like light, afraid of smoke and dust: sweet-scented osmanthus like sunshine, good warmth, high temperature resistance, but not cold resistance. During the growing period, it should be maintained in a leeward and sunny place. The period from June to August is the period of flower bud differentiation and formation of sweet-scented osmanthus. If sufficient sunlight is given for about 10 hours and high temperature of 30-35 degrees every day, it can promote bud pregnancy and increase flowering rate. But in summer, avoid shading so as not to differentiate flower buds. During the overwintering period, if the temperature is less than 4 degrees and the light is insufficient, it is easy to lead to defoliation in early spring and affect the flowering in the coming year.

4. Timely watering: the number of times sweet-scented osmanthus is watered depends on the weather and plant growth at that time. Generally, it is watered every 2-3 days in spring; in summer, the temperature is high and the evaporation is large, which coincides with the stage of sweet-scented osmanthus development and flower bud differentiation, which is watered once a day; in the first and middle of September, the basin soil needs to keep moist, otherwise it is not easy to bloom. But in the flowering period, can not pour water, in order to prevent falling flowers. Drain water in time on cloudy and rainy days to prevent stagnant water from rotting the roots. At ordinary times, it is appropriate to keep the water content of the basin soil about 50%. Before entering the room in winter, it should be watered once, during the maintenance period, every 10 days or so, at noon on a sunny day, but the water temperature is close to the room temperature.

5. Skillfully applying topdressing: sweet-scented osmanthus likes fertilizer and needs to strengthen topdressing, from April to May, once every half month, from June to July, every 7 to 10 days. It was applied for the last time in early August, so that sweet-scented osmanthus not only grew luxuriantly, but also blossomed more and fragrant. Can use rotten cake fertilizer water, chicken, duck and pigeon dung, fish scale water, calcium superphosphate and bone meal and so on, if the fertilizer is insufficient, there will be fewer branches, flowers, and not fragrant.

6. Proper pruning: Osmanthus fragrans have developed roots and strong germination. Adult sweet-scented osmanthus trees are smoked slightly twice a year. Therefore, in order to make it blossom and flourish, the physiological balance of reproductive growth and vegetative growth should be maintained, and proper shaping and pruning must be carried out. After the Mid-Autumn Festival, cut off all the overgrown branches in summer and autumn, leaving the strong spring branches, and then cut off the thin and weak branches, dense branches, disease and insect branches before sprouting next spring. In this way, it is not only conducive to ventilation and light, but also completely concentrate nutrients on spring branches and flower buds, which creates a good prerequisite for autumn flowering and can achieve the effect of "killing a few birds with one stone".

The above is a brief introduction to the cultivation methods of sweet-scented osmanthus. After reading the above, everyone can try to plant sweet-scented osmanthus, which may have unexpected results.
