When to plant osmanthus and when is the best time to plant osmanthus seedlings?

Every year in April and May.

Cultivation method: sowing method: some osmanthus trees.

After flowering, it will produce oval-shaped fruits. In the second year, when the fruit ripens and turns purple-blue, it is harvested, the outer skin is removed, and after drying in the shade (not in the sun), it is mixed with some damp yellow sand and put into a washed can.

, put it in the refrigerator door, refrigerate it until the next year's sting (early March), take it out and wrap it in a damp rag, and put it in a bowl in a sheltered place indoors to germinate. When the buds first appear, they are transplanted into soft potting soil and sprinkled with a layer of fine soil. After half a month, you can spit out the seedlings and become the osmanthus seedlings you cultivate by yourself.

High pressure method: every year, select the two-year-old sturdy osmanthus tree branches at shoulder height, cut a circle along the branch at 15mm below the branch bud eye, and then cut a circle at about 20mm down, peel off the bark between the two circles, and set half a plastic bag 20mm below the peeling place, and tie it firmly with a rope. In addition, wrap the soft wet soil mixed with corn soup in the plastic film, wrap the wet soil with the plastic film facing upward, and then tie the upper end of the plastic film to the branches with a rope.

After that, every 10 days or so, loosen the upper end of the rope, pour in an appropriate amount of water, and then tie the rope tightly. After a few months, the rope was removed, the plastic film was peeled off, and the roots were entangled in the soil. Cut off the branches below the root system and plant them in the potting soil, that is, a new osmanthus sapling.

Osmanthus seedlings are cultivated to reproduce asexually by cuttings.

Mainly. The questions about the harvesting, seed treatment and sowing time of osmanthus seeds are as follows:

Post-harvest treatment: Seed seeds with river sand.

After mixing, the outer seed coat is rubbed until the yellowish-white bony seed shell is free of any fleshy residue, and the empty seed is floated away.

Seed storage, osmanthus seeds are physiological post-ripening type, must go through a long period of sand storage, and can germinate and emerge only after the ripening process is completed; For this purpose, the washed seeds can be mixed with wet sand, stored in a large pot or water tank, the mouth of the pot or tank is covered with glass (or wooden board) to moisturize and prevent rodents, and it can be placed indoors in winter to keep it freezing. During the storage period, the sand particles are always moist, and the water holding capacity of the sand in the early stage of sand storage is 10, and it can be increased to 50 in the middle and late stages.

Sowing requirements: generally with strip sowing method, after sowing covered with a small amount of straw, and shade, the seedling height of the year can reach 15 20 cm. After being cultivated in the nursery for 2 years, transplanting is carried out in the spring of the 3rd year, and flowering is carried out after 10 years.

Depending on the weather, it should be in season.

However, it generally takes about 10 years for an osmanthus tree to grow from a seedling to a large tree. The growth rate is slow. In the whole growth process of osmanthus, the growth rate of osmanthus at the seedling stage is the fastest.

The growth rate of grafted seedlings is slower in the current year or the following year, and then the growth rate is accelerated, generally growing about 20-30 cm in that year, and the best can reach 60-70 cm. Therefore, in general, osmanthus seedlings can grow an average of 20-40 cm a year.

In terms of dry diameter and thickness, the osmanthus tree can only grow one centimeter thick from the first year to the third year, about the thickness of chopsticks, that is, the diameter of the rod is only 1 cm. It takes at least five to six years to grow from a sprout to a diameter of 3 cm.

Small osmanthus seedlings we will give it drying, and the height of drying is divided into several types. One is the rice dinggan, and the other is the high-pole osmanthus tree. There is also a 1-meter fixed stem, which is a low-branched osmanthus tree.

Osmanthus trees with higher branches grow more slowly, and it takes about 8 years for a tall 10 cm osmanthus tree and about 6 years for a 10 cm osmanthus tree with a low branch.

Osmanthus planting methods and precautions:

Soil: Use loose, fertile, well-drained and acidic soil. Temperature:

Preferably between 15-28. Humidity: The air humidity should be around 85%.

Light: Osmanthus is more light-loving, and 6-8 hours of light a day is conducive to growth. Fertilization:

Organic fertilizer is the main fertilizer, and the growth period is once every 10 days. Note that the pot should be changed every spring.

1. Soil. The requirements for it are relatively high. It is required to be loose, nutritious, easy to drain, and must be acidic. Do not use alkaline soil, and do not use clayey soil with poor drainage.

2. Temperature. It likes warmth and is best kept between 15-28. In winter, it is necessary to pay attention to the cold, and it is best to move the potted plants indoors. Of course, in the summer, if the temperature is too high, you have to cool it down.

3. Humidity. The relative humidity of the air has a great influence on its growth, and it is best to keep it at 85 percent. Especially in summer, if the humidity is too low, you can spray some water.

Fourth, light. It inherently prefers light. Especially during the flowering period, it is necessary to maintain sufficient light exposure. In general, 6-8 hours of light is best in a day. Except for the particularly strong light at noon, light can be received at all other times.

5. Fertilization. To fertilize osmanthus, organic fertilizer can be the mainstay. From the time of bud break in spring until July, you can apply cake fertilizer every 10 days.

After July, Trim granules compound fertilizer can be used. At the beginning of September, in order to promote its flowering, it is necessary to use a fertilizer, this time mainly with potassium dihydrogen phosphate.

6. Precautions.

Not only should you pay attention to the choice of soil, but also change the soil regularly. Once a year is best, in the spring. After pruning it first, change the soil and put it on the pot.

1. Osmanthus trees are best planted in spring, suitable for planting osmanthus seedlings in spring, and also suitable for propagating osmanthus seedlings, spring rain, warm climate, sunshine, is the season of all things sprouting, at this time the survival rate of planting osmanthus trees is very high, and the planting effect is very good.

2. In addition, osmanthus trees can also be planted in autumn, the temperature is cool in autumn, the autumn rain is pleasant, the temperature, light and humidity can meet the growth of osmanthus trees, and it is possible to plant osmanthus seedlings or cuttings to propagate osmanthus seedlings after autumn. It is best to sow osmanthus trees in autumn in October of the same year or spring in the following year.

Osmanthus is best sown in the spring and autumn of 2010-2010. The planting climate is suitable from February to May in spring and October to November in autumn, and the germination rate is high.

Osmanthus planting time.

1.Germination period: Osmanthus begins to germinate in late January, and germination is also affected by different temperatures.

2.Germination period: Osmanthus will enter the germination period in mid-February when the temperature exceeds 6 degrees, and last for 3-4 days.

3.Leaf development period: osmanthus 11-12 degrees start to smoke for five days.

4.Closure period: Osmanthus is closed for five days at 16-17 degrees in late April.

5.Defoliation period: Osmanthus enters the defoliation period at 17-18 degrees, which is five days for the hand or period.

6.New and old color consistency period: Osmanthus will last for 5 days in late May when the temperature exceeds 20 degrees, entering the same period of new and old colors.

Osmanthus growth cycle.

Osmanthus has now been sold for 1,500 yuan for ordinary trees, and 2,800 yuan for fine trees, so it is still very profitable to grow osmanthus. Take osmanthus 1 meter seedlings as an example. In 8 years, a total of more than 8,000 yuan can be invested, and the income can reach more than 70,000 yuan.

Osmanthus planting costs and profits.

Before planting osmanthus to dig a big pit, before planting envy potatoes to destroy some organic fertilizer, you can also add some plant ash, so that the growth of osmanthus will be better. Osmanthus seedlings should be planted with soil to facilitate survival.
