Planting method of osmanthus trees in Guangxi
1, variety selection
Different varieties of Osmanthus fragrans have different flowering time, such as laurel and four seasons osmanthus, which are all early flowering varieties and have the characteristics of flowering several times a year. Some varieties need a long vegetative growth period from seedling to flowering, such as Jingui, Yin Gui and Dangui, which often take several years to blossom. So try to choose short and strong early flowers for planting.
2. Pot soil preparation
Osmanthus fragrans likes to grow in slightly acidic soil rich in humus (PH value should be 5.6~6), and it is forbidden to grow in alkaline soil or cohesive soil. Culture soil can be mixed with 4 parts humus soil, 3 parts sandy soil and 3 parts decomposed manure dry powder, or mixed with 5 parts mountain mud, 3 parts humus soil and 2 parts sandy soil for application. In order to overcome the alkalinity of soil and water quality, 0. 1%~0.2% ferrous sulfate solution should be sprayed once every half month during the growing period to make its branches and leaves dark green, which is also beneficial to growth.
3, like light, afraid of smoke and dust
Osmanthus fragrans likes sunshine, so it is warm and resistant to high temperature, but not cold. During the growing period, it should be maintained in the leeward and sunny places. June-August is the flower bud differentiation and formation period of osmanthus fragrans. If enough sunshine and high temperature of 30~35 degrees can be given every day for about 10 hour, the bud pregnancy can be promoted and the flowering rate can be improved. But avoid shading in summer to avoid flower bud differentiation. If the temperature is below 4 degrees in winter and the light is insufficient, it will easily lead to defoliation in early spring and affect the flowering in the coming year.
4. Water in time
The frequency of watering osmanthus depends on the weather and plant growth at that time. Generally, water is poured once every 2 to 3 days in spring; In summer, the temperature is high and the evaporation is large, which is in the stage of osmanthus development and flower bud differentiation. Water it once a day. In the first half of September, the pot soil needs to be kept moist, otherwise it is not easy to bloom. But in flowering period, don't water the flowers to prevent them from falling. Rainy days should be drained in time to prevent water from rotting roots. It is advisable to keep the water content of basin soil at about 50% at ordinary times. Before entering the house in winter, water it once. During the curing period, it should be watered once every 10 day, but the water temperature should be close to room temperature.
5. Skillfully apply topdressing
Osmanthus fragrans likes fertilizer, so it is necessary to strengthen topdressing. Apply it every half month from April to May and every 7~ 10 day from June to July. Apply it for the last time in early August, so that osmanthus not only grows luxuriantly, but also blooms more and smells more fragrant. It is suggested to use trimer potassium dihydrogen phosphate fertilizer.
6, appropriate pruning
Osmanthus fragrans has developed root system and strong germination. Mature osmanthus trees pump water slightly twice a year. Therefore, in order to make it flourish, it is necessary to maintain the physiological balance between reproductive growth and nutritional growth, and it is necessary to carry out appropriate shaping and pruning. After the Mid-Autumn Festival, all the long branches born in summer and autumn will be cut off, leaving strong spring branches, and then the weak branches, dense branches and pests will be cut off before the next spring germination.
This is not only conducive to ventilation and light transmission, but also enables nutrients to be completely concentrated on spring branches and flower buds, creating a good prerequisite for autumn flowering and receiving the effect of "killing several birds with one stone".
