Osmanthus tree planting technology network of osmanthus tree planting technology

1. Temperature: Osmanthus tree likes a warm environment, the average temperature of the planting area is 14-28, the average temperature in July is 24-28, the average temperature in January is above 0, its lowest cold-resistant temperature is -13 °C, the best temperature is 15 to 28 °C, and the winter in the south of the Qinling Mountains and the Huai River in China can be successfully spent in winter. However, it is not cold-tolerant, but it is also a relatively hardy species compared to other evergreen broad-leaved species.

2. Water content: Osmanthus trees like moisture, humidity is very important for the growth and development of osmanthus, requiring an average annual humidity of 75 85 and annual precipitation of about 1000 mm, especially young and adult trees need more water when flowering, if drought will affect flowering. But also avoid standing water.

3. Sunlight: The osmanthus tree likes sunlight and does not like cloudy days, it will grow very lush in a sunny environment, with sufficient flowering period and intensive flowering; In shady places, the branches will be sparse, the shade will be sparse, and the flowers will be scarce, if you are potting indoors in the north, it is necessary to pay attention to the sufficient light to promote growth and bud formation. Strong sunlight and shade are not conducive to their growth and usually require 6 to 8 hours of light per day.

4. Soil: The osmanthus tree does not have strict requirements for the soil in which it is planted. With the exception of alkaline soils and low-lying soils or soils that are too viscous and poorly drained, general soils can grow, but deep, loose, fertile, well-drained acidic sandy loam soils are the most suitable.

5. Purify the air: Osmanthus has a certain resistance to harmful gases such as chlorine, sulfur dioxide, hydrogen fluoride, etc., and has a strong ability to suculate the letter, which is suitable for planting in a ventilated and well-lit place.

1. Generally, their planting is divided into three methods: sowing, cuttings and grafting.

2. If you sow seeds, you can directly use osmanthus seedlings for cultivation.

3. Cuttings are to cut a branch of about 10 cm from the plant, leave 3 to 4 leaves on it, and then plant.

4. Grafting is more complicated, and it is advisable to carry out it by professionals in the industry, which is divided into two types: relying on grafting and abdominal grafting.

Before planting osmanthus trees, it is necessary to choose loose and slightly acidic sandy soil, dig a 20cm deep pit on it, and then apply an appropriate amount of rotting manure to stir it to make it a base fertilizer. The osmanthus tree is planted directly in the pit, watered and maintained after the soil is compacted, and the later maintenance work is done to provide enough nutrients and light to make it grow vigorously.

Loose soil should be selected for planting osmanthus trees, and alkaline or too sticky soil should not be used, which is easy to make the roots of osmanthus trees breathe poorly and cannot absorb nutrients normally for growth. Generally, it is planted in loose, slightly acidic, sandy soils.

Dig a pit of the right size and depth in the prepared planting soil, so that the root system of the osmanthus tree can better take root in the soil. Usually, it is necessary to dig a large pit with a depth of about 20cm, and apply an appropriate amount of decomposed manure to the soil at the bottom of the pit, and stir it evenly with the soil as base fertilizer.

According to the osmanthus tree planting technology, put the osmanthus tree directly into the dug deep pit, pay attention to its root system can not be damaged, it is best to let the root system in a stretched state in the pit. Then start filling the soil, and after burying the roots, the soil should be compacted to avoid lodging due to unstable roots.

After planting, it is necessary to do a good job of maintenance, first water it thoroughly, wait until the soil is white, and then water it appropriately to avoid water accumulation that causes it to rot roots, and apply thin fertilizer once a month. It is also necessary to pay attention to timely weeding, regularly loosen the soil to keep the soil loose, and provide sufficient light for the osmanthus tree.

First of all, the fertilization and simple maintenance methods of osmanthus are introduced as follows:

Osmanthus likes fertilizer, and no fertilization for a year is very unfavorable to the growth of osmanthus trees. Osmanthus trees should not use chemical fertilizers as much as possible, and should use more farm fertilizers. Osmanthus trees are particularly fond of pig manure, and there is a folk proverb called "to make osmanthus fragrant, beat the pig feces tank".

There is no pig manure in the city, and you can use well-rotted cake fertilizer (or Huimanfeng, Chunquan Baba.

3. Opel and other high-efficiency active fertilizers). Fertilization should be applied thinly and frequently, starting from February every 10 to 15 days and ending in August. After August, phosphorus and potassium fertilizer should be applied as the main fertilizer, and liquid fertilizer of rotted chicken and duck manure should be applied every 10 days to promote the differentiation and formation of flower buds.

Reduce the amount of fertilizer during the flowering period, change to apply phosphorus and potassium liquid fertilizer once every half month, and avoid applying nitrogen fertilizer. After flowering, nitrogen liquid fertilizer should be applied in time, and the fertilizer should not be concentrated and the amount should not be too much, so as to avoid causing new branches in autumn and consuming plant nutrients.

The usual care measures are as follows:

1 Place to place: Osmanthus bonsai should be placed in a warm and sunny place, and it should be properly shaded in summer to avoid direct sunlight.

2. Change the pot: change the pot once every 2 to 3 years, and use the new soil prepared by 5:3:2 or half of the saprolite and sandy loam soil according to the 5:3:2 preparation, and the flower pot requires a large diameter.

3. Watering: Osmanthus pot soil should master the principle of "not drying, not watering, watering thoroughly". Generally, water every 3 4 days in spring and autumn, water once a day in high temperature in summer, water every 7 10 days in winter, water in the morning and evening in summer, and water around noon in winter, so that the water temperature is close to the soil temperature, so that it will not be cold and hot and hurt the root system.

Watering in autumn should be appropriate, and in the rainy season, it is necessary to prevent the potting soil from becoming too wet or waterlogged.

4. Pruning: The shaping and pruning of osmanthus should be carried out after autumn, and the upper branches should be cut off to balance the tree momentum. Branches that are too dense should be thinned and diseased branches should be removed to concentrate nutrients for flowering.

Plastic pruning combined with water and fertilizer management can improve the robust growth of osmanthus bonsai and maintain a beautiful posture.

5 pest control: common diseases of osmanthus are leaf spot, coal stain disease, algae spot, root rot, iron deficiency disease, etc., when the disease is found, the osmanthus can be moved to the outdoor spraying to prevent and control. Leaf spot disease, coal stain disease and algal spot disease can be controlled by spraying Bordeaux liquid or 5% carbendazim 500 1000 times liquid; For the prevention and control of root rot, attention should be paid to keeping the soil loose and breathable, and not accumulating water; If root rot is caused by fungi, the roots can be watered with 200 300 times of dysenammonium.

Common insect pests of osmanthus include leaf wasps, whiteflies, mites, white scales, yellow thorn moths, etc. Leaf wasps, whiteflies, mites can be sprayed with 40% dimethoate 1500 3000 times liquid, except for the white scale except for manual brushes, in the first and second generation of nymphs, can be sprayed with 40% 500 times of pine borer.

You adopt the sowing bar and the benefits are high.
