How is osmanthus grown? How osmanthus should be planted

Osmanthus likes fertile and well-drained slightly acidic soil, it is a long-day plant, so the cultivation of osmanthus must give it sufficient light, insufficient light its branches will become very thin and very weak, and flower buds are difficult to form! We need to reduce watering before the shoots germinate. During its growth period, we can use a general-purpose water-soluble fertilizer every half a month or so to promote the germination of branches.

4 In May, the osmanthus fruit is ripe, and it can be harvested when the peel turns from green to purple-black. Osmanthus seeds have the effect of ripening, at least half a year of sand storage time, after harvesting, sprinkle water and pile up, remove the pulp, put in a cool place to make the seeds naturally dry, mixed sand storage, sand storage can be sown in autumn or spring after sand storage. During the sand storage period, it should be checked frequently to prevent the seeds from rotting or rodent infestation.

Seeding and propagation generally adopts the method of strip sowing. Before sowing, the land should be prepared, and sufficient basal fertilizer should be applied, and it can also be sown in the indoor seedbed. When sowing, the seed umbilicus is placed on the side to avoid bending the radicle and young stems, which will affect the growth of seedlings in the future.

After sowing, cover with a fine layer, and then cover with grass, shade and moisturize, often keep the soil moist, and the seedlings can emerge in the same year. The amount of seeds per mu is about 20 kg, and about 30,000 seedlings can be produced. Seedlings can be transplanted and cultivated in the third year after 2 years of growth in the seedbed.

Seedlings bloom late, and can only bloom after 8 to 10 years of planting.

1. Potting soil selection: When potting osmanthus, the potting soil can be used mountain mud Saprophyllous soil: garden soil:

Sand soil is prepared according to 5:3:2, and garden soil can also be used:

Manure: River sand at a ratio of 1:1:

Make up. When potting, well-rotted organic fertilizer, bone meal, etc. should be added as base fertilizer.

2. Flower pot selection: When potting osmanthus flowers, it is recommended to choose a tile pot with good air permeability to plant. The bottom fan is followed by tiles to facilitate drainage.

3. Potting time: The planting time of osmanthus should be selected in late autumn from November to early December, or from February to early March in spring, and seedlings should be potted in spring as much as possible to avoid frost damage in winter. After potting, it should be watered thoroughly, put it in a ventilated place to slow down the seedlings, and move it to a sunny place for maintenance after 1 week.

4. Water management: Potted osmanthus should be kept moist in potting soil, and attention should be paid to drainage in the rainy season to prevent root rot due to more water. When flowering in autumn, the potting soil should be avoided from being too wet, otherwise it is easy to fall flowers and buds.

5. Fertilization: When germinating in spring, 30@ cake fertilizer water should be applied once every 10-15 days, and after July, potassium dihydrogen phosphate or superphosphate should be added at the same time as the cake fertilizer water is applied to promote the differentiation of flower buds.

It should be planted in spring or autumn, especially on cloudy or rainy days.

Cultivation method: Choose a well-ventilated, well-drained and warm place, with plenty of light or semi-shade. Transplanting should be done well to ensure the survival rate. The planting soil is required to be acidic, and alkaline soil should be avoided.

The ratio of potted osmanthus potting soil is 2 parts of humus soil, 3 parts of garden soil, 3 parts of sandy soil, and 2 parts of well-rotted cake fertilizer, which are mixed evenly, and then potted or repotted, which can be carried out before budding in spring.

Watering and fertilizing. Before planting, herbaceous ash and organic fertilizer should be mixed into the tree hole, and watered once after planting. Keep the soil moist before the new technology is launched, and do not water with fertilizer. Generally, nitrogen fertilizer is applied once in spring, phosphorus and potassium fertilizer are applied once in summer, so that flowers and leaves are luxuriant, and organic fertilizer is applied once before winter, mainly with well-rotted cake fertilizer and manure.

Avoid thick fertilizer, especially feces and urine. Potted osmanthus should be put into a low-temperature greenhouse in the northern winter, pay attention to ventilation and light transmission indoors, and water less. After leaving the house in April, the amount of water can be increased appropriately, and the appropriate amount of light fertilizer water can be poured in the peak growth season, and the fertilizer water can be slightly thicker in the flowering season.

Light temperature. In the south of the Yellow River Basin, it can be cultivated in open field for wintering. Potted plants should be moved indoors in winter, placed in a sunny place, so that they can fully receive direct sunlight, and the room temperature should be kept above 5, but not more than 10. After germination in April of the following year, it is moved outdoors, first placed in a leeward and sunny place for maintenance, and then gradually moved to a ventilated sunny or semi-shaded environment after stable growth, and then normal management.

Insufficient light during the growth period affects the differentiation of flower buds.

Osmanthus cultivars can be propagated by sowing, grafting, cuttings or striping.

1. Osmanthus is planted in the open field more often than in early spring. The best time for cuttings is mid-May to late June (autumn cuttings can be from mid-August to late September).

2. The open field planting site should choose a place with sufficient sunlight, good drainage and deep soil. Before planting, dig a big hole, apply more organic fertilizer, and add some plant ash at the same time, and the seedlings need to be transplanted with soil ropes to facilitate survival. Fill with water after planting.

Liquid fertilizer is applied once after survival. 7 In August, water and fertilizer are applied 1 2 times. Before winter, it is now applied with decomposed compost.

In the future, the fast-acting nitrogen fertilizer was applied once in late March, the fast-available phosphorus and potassium fertilizer was applied once in July, and the organic fertilizer was applied again in October. After each fertilization, it is necessary to irrigate and weed in time, and pay attention to the timely prevention and control of pests and diseases, so that the growth can be accelerated, and the flowers are lush and fragrant every year.

3. To make osmanthus bloom more and fragrant, potted plants need to grasp the five main links of selecting potting soil, timely watering, skillful topdressing, proper pruning, and prevention and control of diseases and insects.

4. Precautions for planting osmanthus trees: osmanthus likes slightly acidic soil. Potted plants can choose 5 parts of mountain mud or humus, 3 parts of garden soil, 2 parts of sandy soil mixed modulation or half of humus and sandy loam soil as culture soil.

5. Watering should be timely. Watering should master "two less and one more", that is, less watering before the occurrence of new shoots, less watering in the rain and rain, and more watering in dry weather in summer and autumn. It is advisable to keep the water content of the potting soil at about 50% at ordinary times.

Especially in autumn, if the potting soil is too wet, it is easy to cause flower drop. On rainy days, pay attention to inspection, if there is water in the pot, you need to pour water from the side basin in time to avoid root rot for a long time.
