The breeding and breeding methods of "evergreen shrub" Haitong!

Haitong, also known as Qi Li Xiang, Baozhu Xiang, Shan Rui Xiang, etc., can usually be planted as hedges, alone and clustered at the edge of the grass, at the edge of the forest or by the door, or by the roadside. Here is an introduction to the breeding and breeding methods of "evergreen shrubs"!

I. the breeding mode of Haitong

1. Sowing method

Many people may not know that Haitong has its own seeds. Haitong's seeds are hidden in its pulp, and the fruit is cyan when it is not ripe, and every year between October and November, the fruit slowly ripens into yellow, sunburns the peel of the mature fruit, and then knocks out the seeds. In this way, we harvest the seeds of Haitong, and after obtaining the seeds, we have to carry out simple treatment to preserve them. The seeds can be sowed in March next year. Usually, the germination rate of paulownia seeds is about 50%, neither high nor low, but the seedlings grow very slowly, and usually wait two years before they can be formally moved to the basin for planting, or wait for a year or two to move directly to the nursery, and let the roots bring soil masses when transplanting.

two。 Cutting method

Cutting is much more convenient than sowing, the cutting time should be in spring, when Haitong grows new leaves, the buds should be cut out, but the buds are also required, its year should be 1-2 years old, the length should be about 15cm, the cut twigs should be inserted into the sand bed, the main light intensity should not be too strong after cutting, it would be good to be able to accept astigmatism, and the humidity should be kept good. In this way, Haitong can take root in about 20 days, normally watered and fertilized, if the branches are too long and pruned in time, Haitong can be transplanted to the nursery after 2-3 years.

Second, the culture method of Haitong

1. Upper basin

The upper basin of Haitong needs to be planted on the deep basin, and a circle of hard plastic sheets with high 5~8cm is added along the upper part of the basin, and the bottom of the basin is padded to broken tiles, so that the root can be improved accordingly, and the pot soil is slightly lower than the plastic circle, so that the survival of deep pot and shallow planting will not be affected.

two。 Light

Haitong has a strong ability to adapt to light. It can be put outdoors in summer and in a cool place in the shade of flowers if possible. Strong light does no harm to the plant.

3. Temperature

Haitong needs about 50% air humidity, and the suitable growth temperature is 15: 30 ℃. It is kept in a cold and ice-free room in winter, and the lowest temperature is 5 ℃.

4. Watering

Haitong consumes a lot of water in summer and should be watered frequently. If the temperature is low in winter, the amount of water will be reduced accordingly.

5. Fertilizer application

Haitong is fertilized every two weeks during the growing season, and no rotational fertilizer is used in other periods.

6. Change the basin

The pots of young plants of Haitong should be changed once a year, and the adult plants should be changed every 2 to 3 years. The pots should be mixed with 1 big 3 rotten leaf soil and 2 big 3 clays or loam. The withered roots should be cut off when changing the pots, and newly cultivated soil containing more organic matter should be added to the basin soil.

7. Pruning

Haitong has strong branching ability and resistance to pruning. It needs pruning and shaping at the beginning of spring in order to maintain a beautiful tree shape. If you want to restrain its growth and propagate its branches and leaves, you should cut its top and prune it into various forms when it grows to the corresponding height.

The above is the introduction of the breeding methods and breeding methods of Haitong by Tuliu.com, which has a strong adaptability to climate, can withstand cold and summer heat. In the south of the Yellow River basin, it can survive the winter safely in the open field, has strong adaptability to soil, and can grow normally in clay, sand and light saline-alkali soil.
