Culture methods and matters needing attention of Penglai pine

Penglai pine

Penglai pine alias Hydrangea pine, water pine, pine leaf asparagus, pine leaf asparagus, pine bamboo grass, etc., is a perennial shrub-like herb of asparagus.

The plant height of Penglai is 30-150cm, the stem is erect or slightly scattered, and the Lignification is shrub-like. With white hypertrophic fleshy roots.

The plant has a large number of tufted stems, much branched; the stem is gray-white, the base is lignified; the branchlets are slender, the leaves are short pine needles, and the clusters form clusters, which are very similar to five-needle pine leaves. The new leaves are tender green and the old ones are dark green. Flowers light red to white, fragrant, flowering from July to August, berries black.

Growing environment of Penglai pine

Penglai likes a warm, moist and shady environment. The suitable temperature for growth is 20-30 ℃, and the overwintering temperature should be above 3 ℃. Like warm, humid and semi-overcast environment. Not resistant to cold, afraid of strong light exposure and high temperature for a long time, not resistant to drought and stagnant water. The suitable temperature for growth is 20-25 ℃; if the temperature in winter is not lower than 10 ℃ or 5 ℃, it is easy to be frozen; when the high temperature in summer exceeds 35 ℃, the growth stops and the leafy stem turns yellow. It is better to use loose and fertile rotten leaf soil.

Propagation mode of Penglai pine

Penglai pine is generally propagated by ramets and can also be sown, but it grows slowly in the seedling stage.

1. Ramet propagation:

It can be done in spring and summer when the basin is changed, the old plants with dense growth are removed from the basin, and the underground roots are divided into several clumps, so that each clump contains 5 branches (pay attention to less root damage), and each clump is re-planted in the basin with newly cultivated soil, watered thoroughly, and placed in a semi-shady place to restore growth.

2. Seed propagation:

The seed reproduction and germination rate of Penglai pine can be as high as 90%. It can be picked back in time from mid-September to mid-October when the cones are ripe, first stacked for 5-7 days, then exposed to the sun for 3-4 days, beating and turning, seeds protruding, timely water separation, removal of empty sundries, and bag storage after drying for the winter. Penglai pine has thick seed coat and slow germination, so it is suitable for early sowing. The slightly acidic soil with good drainage is selected in the nursery, and sufficient base fertilizer is applied when preparing the soil. Sprouting was carried out before sowing. Soak the seeds in cold water for 3-7 days (change the water during soaking), mix the seeds with hydrated lime after soaking, and sow the seeds after the seed coat is cracked. It began to sprout and unearthed in mid-late April, and the seedlings of that year could reach 8-12 cm.

1. Mining:

From the mountain woodland, choose Penglai pine which is strong and short in shape.

For wild seedlings, it is better to grow small old tree stumps in stone gaps, cliffs and ditches. When digging, pay attention to protect the accessory root and fibrous root, and then raise the embryo in the lower ground, and then put on the basin shape again after the next spring.

2. Select the basin:

It is appropriate to use purple sand pottery basin or glazed pottery basin for Penglai pine. Just put on the pot cultivation, can first use the plain burning tile basin with good air permeability, and then change it into the elegant purple sand shallow basin after taking the basin. In addition to the cliff type with deep thousand-barrel basin or deeper square and round basin, generally rectangular medium-shallow basin is appropriate. The shape of the basin can also be determined according to the tree shape, such as the curved dry type can use a drum-shaped shallow round basin, the basin color can choose purple or light yellow. Penglai pine can adapt to many kinds of soil, but it is not resistant to salt and alkali, and it is better to use deep, moist, loose and slightly acidic sandy loam soil. Potted with mature pastoral soil, rotten leaf soil, appropriate amount mixed with sandy soil. The best pot planting of Penglai pine is before sprouting in March, and it can also be planted in autumn, but it is disadvantageous to root. When digging saplings, you should take shelter soil. You can cut short the overextended straight roots and cut off the withered roots. If planted in a shallow basin, you should pay attention to the fixation of the trunk, put the iron rod along the bottom hole of the basin, tie it to the thicker root with a slightly thicker wire, get out of the pot hole, and then tie it tightly on the iron rod, so as not to shake in the wind and loosen the root system, affecting survival.

3. Soil:

Penglai potted plant is often mixed with rotten leaf soil, land and river sand as substrate, and slightly mature base fertilizer is added when planting. Spring and summer is its peak growing season, which needs sufficient water, but it is not suitable to make the basin soil stagnant water, so as to avoid root rot; after the end of autumn, the amount of watering should be gradually reduced to make the basin soil slightly wet. In order to make the branches and leaves grow luxuriantly, we should pay attention to supplement nutrients in the growing season, and generally apply liquid fertilizer 1 Mel twice a month. It likes semi-shade, hot summer should pay attention to shade, to prevent the sun exposure, so as to avoid branches and leaves burning or yellowing.

4. Processing:

The processing and modeling of Penglai pine can be dominated by climbing and supplemented by pruning. Climbing with wire or brown wire. Penglai pine branches are relatively soft, easy to climb with wire, flexion and extension freely. If the saplings of 2 ~ 3 years old are taken as materials, the trunk is bent to a certain extent, the branches hindered by the shape are cut off, and then the retained lateral branches are tied into a horizontal or slightly drooping shape, and then the wire is removed after growing for one year, the angle is re-adjusted, and then climbing, it can be formed in a few years. For example, Penglai pine stumps excavated in the mountains can be processed in pots only after raising embryos for a year. Pose modeling must be due to material treatment, make full use of the natural form of raw materials, a little artificial climbing, so that it has a natural wild interest.

5. Tree shape:

Penglai potted landscape can be made into straight dry type, oblique dry type, curved dry type, cliff type and so on, each with its own charm. Straight dry type, vigorous tall and straight simple; oblique dry type, chic and healthy and vigorous; qu dry type, "meandering and bending back to flat potential, meandering and undulating dragon shape"; cliff type, gully cliff ancient pine, dangerous, Canglong probe head, want to dive all over the world.

Cultivation and management of Penglai pine

1. Temperature:

Penglai pine began to grow when the temperature was above 15 ℃, and 20-30 ℃ was the most suitable for its growth. Potted plants in summer should be placed in a ventilated semi-cool place to avoid direct light, otherwise it is easy to cause scorched leaves and affect the ornamental value. Spring and summer growth season, need sufficient water, but the basin soil can not accumulate water, otherwise it is easy to cause rotten roots and fallen leaves. Fertilize once a month and apply more nitrogen and potash fertilizer. After autumn, the temperature drops and the growth weakens, so watering should be reduced gradually. To beautify the shape of the plant. It needs to be trimmed frequently. Put in more than 5 ℃ indoor maintenance in winter, as long as you keep the basin soil moist.

2. Water and fertilizer:

The growing season should be fully watered, the temperature decreases after autumn, and watering should be reduced gradually. In order to make the branches and leaves luxuriant, more nitrogen and potash fertilizer can be applied, about once every 15 days.

3. Change the basin:

The basin should be changed once a year in spring, so that the stems and branches of Penglai pine can be tall and straight, green and luxuriant.

4. Pruning:

In order to maintain the shape of the plant, it needs to be pruned frequently.

5. Diseases and insect pests:

Penglai pine has fewer diseases and insect pests, but red spiders and shell insects may occur when it is hot and dry, which can be sprayed with 1000 times omethoate EC.

Pest control of Penglai pine

Penglai pine is mainly harmful to leaf blight and can be sprayed with 1000 times of carbendazim wettable powder. Insect pests include whitefly and scale insects, which can be sprayed with 1000 times of oxidized Dongguo milk.

The main value of Penglai pine

Flower beds can also be arranged on warm ground. The utility model has the advantages of simple cultivation and management and good shade tolerance, so it is suitable for planting in small and medium-sized pots and for indoor arrangement; at the same time, it is also an excellent material for flower arrangement.

In summer, when the temperature exceeds 35 ℃, Penglai pine will stop growing and the leaves will turn yellow. at this time, it is necessary to do a good shading work in time to avoid strong light exposure, and often spray water to keep the plant green and beautiful.

The pot-changing work of Penglai potted plant is generally carried out in spring after 2-3 years, and the dense plants and long branches are cut off at the same time to facilitate its ventilation and light transmission. During the growing period, we should also pay attention to cutting off dead and diseased branches at any time, so as to keep the plant shape symmetrical and beautiful.

Penglai pine diseases and insect pests are less, mainly red spiders and shell insects, pay attention to timely spraying for control.

Culture methods and matters needing attention of Penglai pine what to do if the leaves turn yellow

Penglaisong, this is a lot of people like farming, the growth is more luxuriant, look at it feel very happy, Penglai breeding methods and matters needing attention is what? What if the leaves of Penglai turn yellow:

Culture methods and matters needing attention of Penglai pine

Penglai pine culture method:

The main results are as follows: (1) Penglai pine likes to grow in a warm, humid, semi-overcast environment, and the general growth temperature is between 20 ℃ and 30 ℃. The winter growth temperature should not be lower than 5 ℃, and the summer growth temperature should not be higher than 35 ℃.

(2) Penglai pine needs proper shade in summer and can not be exposed to sunlight, and rotten leaf soil with plenty of sunshine in winter.

(3) the soil planted by Penglai pine should be loose and fertile. It is recommended to fertilize Penglai pine every month, which is generally more than double the amount of nitrogen and potassium fertilizer.

(4) to keep Penglai pine well, it is necessary to keep the soil moist with spraying water in order to maintain the beauty of the original emerald green leaves of Penglai pine, but to avoid stagnant water in cultured potted plants, otherwise it will be easier to make the roots and leaves of Penglai fester and damage its growth.

(5) the potted plants will be changed in spring after 2-3 years. Cut off dense plants and long branches to facilitate ventilation and light. Cut off dead branches and yellow leaves at any time during the growing period to make the plant shape symmetrical and beautiful.

Points for attention in Penglai pine culture:

(1) the drop in temperature after spring and summer is the weakening of Penglai during its growing period, so we should reduce the number of times of watering it, but it is also necessary to provide sufficient water to it, and the soil should not be allowed to dry up. In the winter with the lowest temperature, it is necessary to keep the soil in the potted plant moist and avoid watering as much as possible.

(2) Penglai pine has few diseases and insect pests, but red spiders and shell insects may occur when it is hot and dry, so attention must be paid to spraying control.

What if the leaves of Penglai turn yellow:

Although Penglai pine is afraid of high temperature, it likes warmth. Placing it in a place with good sunlight scattering conditions can effectively prevent leaves from yellowing.

Penglai pine has poor drought resistance, so it needs to be watered thoroughly during the alternation of dry and wet, so there is no need for too much. If the branches and leaves are too dense and are in a period of high temperature in summer, it will also cause the leaves of Penglai pine to turn yellow, so it is time to carry out branch construction treatment.

The breeding method of Penglai pine and the treatment method of yellowing leaves are introduced here, so hurry up to breed one.

The Culture method of Penglai Penglai points for attention

The name of Penglaisong is very special, and it is also common in hotels, halls and other places. Penglai decorated interior shows atmosphere, so that the real air appears very concise and neat. For those who like Penglai fluffy, let's take a look at the culture methods and points for attention shared below.

Culture methods and matters needing attention of Penglai pine

I. Culture methods and matters needing attention of Penglai pine-- light

Penglai pine can not accept sun exposure, so it is very necessary to shade it in summer. The strong light directly caused the leaves of Penglai to lose their lustre and even scorch. If you have received burns, put Penglai pine in a cool environment, the growth of Penglai pine will gradually improve.

II. Culture methods and matters needing attention of Penglai pine-watering

Penglai pine needs a lot of watering, at the same time, the basin soil should always remain moist, and the lack of water in summer will cause the leaves of Penglai to droop and dry up. In the peak growing season, it is more necessary to master the principle of not drying and not watering, properly control watering and avoid stagnant water in the basin soil.

III. Culture methods and matters needing attention of Penglai pine-fertilization

Penglai should be fertilized once or twice every 2 months, so that the leaves of Penglai will be bigger and healthier, and the leaves will be more shiny and good-looking. Penglai pine is suitable to use nitrogen fertilizer as fertilizer, but it is not suitable to use nitrogen fertilizer after autumn, so we can consider changing fertilizer into potash fertilizer, so as to enhance the cold resistance of Penglai pine and pass the winter smoothly. No more fertilizing in winter.
