What should I pay attention to in the maintenance of yew nurseries?

Yew cultivation techniques.

1) Yew seedling planting Choose rainy days in spring, and use 2-year-old bare root seedlings or container seedlings to afforestation in the mountains. The afforestation and land preparation method is strip land preparation, digging holes on the belt, the hole specifications are 50cm 50cm 30cm, the plant row spacing is 2m 2m, the topsoil is backfilled into the hole, and phosphorus fertilizer is applied as base fertilizer. It can also be afforested by using dense planting dwarf forest operation method, full reclamation and land preparation, rough furrowing along the horizontal direction, and planting according to density.

2) Tending management After afforestation, loosen the soil, weeding and top dressing 1 2 times a year, and continue to tending for 4 5 years. Yew needs to shade the environment, and the tending is mainly to eradicate malignant weeds, and some miscellaneous shrubs should be retained during midsummer tending to provide lateral shade for yew saplings. The growth dynamics of seedlings had obvious stages, the plant height and stem diameter of the seedlings grew slowly in the first two years, the plant height increased by 20 cm per year, and the growth rate accelerated from the third year, and the plant height of the 3 5-year-old seedlings increased by more than 30 cm per year, and the growth was faster in summer and slow in autumn and spring.

3) Control of major pests Taxus has fewer insect pests, mainly root rot, cataplexy and sunburn. The control method is to prevent stagnant water and shade the seedlings in rainy days at the seedling stage, and spray the seedlings every 1 week with 800 times Tobuzin or half amount Bordeaux solution every 1 week.

Cultivating yew should choose a cool environment of 20 25, pay attention to timely cooling in summer, and put it in the sun in the morning and evening to receive astigmatism, and apply thin fertilizer once a month to make it grow better. Pay attention to proper watering, choose rain or river water and make the water temperature similar to room temperature, and prune and repot in time to make it grow better.

1. When maintaining yew, the temperature needs to be kept at about 20 25 to create a cool environment for it to grow vigorously. It has good cold tolerance and does not need to be kept warm in winter, but it should be cooled down in summer.

2. Astigmatism maintenance In the cultivation methods and precautions of yew, we should also pay attention to astigmatism maintenance, and place it in the sun in the morning and evening for photosynthesis left and right, pay attention to not strong direct light, which will make its leaves yellow, dry and poorly grown.

3. Apply thin fertilizer diligently during the growth period of yew to apply thin fertilizer frequently, and apply a rotting cake fertilizer water about 30 days to make it have enough nutrients to absorb and support the strong growth of yew. Apply a long-acting basal fertilizer in autumn and winter to make it better overwinter.

4. Precautions(1) Water properly

In the usual maintenance of yew, it is necessary to pay attention to the correct watering to keep the potting soil moist, and no water accumulation. The quality of watering is generally selected from rainwater, river water and lake water that are rich in nutrients, and the water temperature should be close to room temperature.

(2) Prune and repot

Yew should also be pruned once in February to keep healthy shoots to thrive, and repotting once a year to allow them to have enough space and fertile new soil to grow.

Yew farming methods include potting soil, light, moisture, and pruning.

1. Pai round pot soil

Yew prefers slightly acidic soils, and alkaline soils can cause poor growth and even death. For the texture of the soil requires proper looseness, too loose it does not like much, the general garden soil and humus can be mixed, in order to have good drainage can be mixed with river sand and perlite.

2. Light

Yew has special requirements for light, and the seedling period is shade-tolerant for one to three years, and the requirements for light will be higher and higher after three years, and it needs full light when it reaches adulthood.

3. Moisture

Yew requires the potting soil to be slightly moist during the maintenance period, and it cannot be completely dry, but it is also afraid of water accumulation, because it is easy to cause root rot.

4. Pruning

Regular pruning should be carried out during maintenance, mainly to pluck the young shoots at germination, so that they can sprout lateral branches and make the branches shorter and denser. If left unpruned, the branches will grow very slender and then droop, covering the lower leaves, and the blocked leaves will die due to lack of sunlight, and the bottom branches will fall off after a long time.

Precautions for yew

Yew pests and diseases are relatively rare, so you don't need to pay much attention to this problem at home. If yew flowers and sets seeds, its aril is edible, and the other parts are poisonous, so it is not recommended for everyone to eat, or it is used as a medicine to eat directly, and the active ingredients in its body are to be refined and processed to be effective.

Yew farming methods and precautions include the following aspects: shading and light, reasonable watering, and pest control.

1. Shade and avoid light

Yew likes shade and is not resistant to strong direct light, when cultivating yew, if it is placed in a bright place, it will lead to dry branches and leaves, and it is necessary to place yew in an environment with sufficient scattered light to promote its photosynthesis and ensure that the environment is ventilated and breathable.

2. Reasonable watering

Yew needs different water requirements in different seasons, when cultivating yew, it needs to be watered every 5-7 days in spring and autumn to keep the soil moist, in summer it needs to be watered every 3-5 days, and sprayed with water mist around the yew, and in winter, it needs to be watered every 7-10 days.

3. Prevention and control of pests and diseases

Yew is prone to root rot, stem rot and root rot during the rainy season, so it is necessary to cut off the severely diseased rhizomes of the plants and spray methyl tobuzin or dixon once a week, while yew is prone to red blight in the high temperature and dry season, and Bordeaux liquid needs to be sprayed.

The flower language of yew

1. Arrogance

In the flower language and legend of yew, the flower language of yew has a proud meaning, because yew is very tall and its plants can grow to more than 15m. It is rare to see such a tall plant in our lives, and compared to other plants, yew is very proud and elegant.

2. Missing

In addition, the yew also expresses feelings of longing, and the yew has a unique appearance, and the bright red fruit gives people a very small and delicate feeling. And the emotions expressed by yew are mainly ** the legend of yew.

Xianghuai Liang said in the earliest time chain regret, there is no yew in the world, suddenly one day, a bird because of the loss of its daughter and with sadness planted a seed and carefully cared for, the bird's longing finally let this seed grow slowly, it became the current yew. And the yew has been waiting for its benefactor.

The soil is slightly acidic, humus-rich sandy soil. Choose bright astigmatism for everyday lighting. Watering varies according to the seasonal climate, and it is also necessary to observe the state of the branches and leaves of the yew.

Fertilization needs to be fertilized regularly during the breeding period, and the fertilizer applied can be farmhouse fertilizer and cake fertilizer. The temperature should be controlled at 20 degrees to 25 degrees, with a maximum of 30 degrees and a minimum of 10 degrees Celsius. In addition, it is necessary to prune yew regularly and control diseases.

First, the breeding method:1. Potting soil: Yew has relatively high requirements for soil, and when we select soil, we generally choose slightly acidic, sandy soil rich in organic matter.

In the case of satisfying these two conditions, the soil should also have the advantages of good drainage and air permeability. If you don't know how to configure, you can mix pastoral soil, peat soil, sandy soil, and decomposed organic fertilizer in a certain proportion.

2. Light: Yew is a plant that does not like light, but we should not breed it in a dark corner for a long time. It should be given a bright, diffuse lighting environment.

In this way, yew leaves will not be dehydrated and wilted due to too strong sunlight, nor will they die due to lack of light.

3. Watering: Watering in combination with the climate, watering every three or five days in summer, every half a month or ten days in winter, and every five or six days in spring and autumn. If the yew has drooping leaves and there is no water on the surface, it means watering.

If the yew appears to shrink, water it as well. Knock on the outside of the pot, there is a hollow sound, and water it as well.

4. Fertilization: During the breeding period of yew, fertilizer should be applied in time, and the fertilizer applied can be farmhouse fertilizer or cake fertilizer.

5. Temperature: The best growth temperature is between 20 and 25 degrees, but as long as the temperature is not higher than 30 degrees and not lower than 10 degrees, it will not have a lot of impact.

2. Precautions:1. When yew leaves turn yellow and insect infestation, it is necessary to start cleaning. We can spray with a certain proportion of potassium dihydrogen phosphate.

2. In the rainy season, the yew should be moved to a sheltered place, because this can effectively prevent the yew root system from accumulating water and rotting.

3. When the branches of yew grow too densely, they need to be pruned off to avoid diseases caused by unsmooth air.

Yew has the characteristics of cold resistance, shade liking, moisture liking, fertilizer liking, fear of drought, flooding, high temperature, and has a wide range of adaptability to soil.

The best soil for potting is loam, which is conducive to the growth of yew with water, fertilizer and ventilation. Although clay retains water and fertilizer, it is not breathable, which is not conducive to the growth and development of yew roots. Although the sandy soil is breathable, it has poor fertilizer and water retention, and is not conducive to the growth of southern yew.

You can also choose peat, perlite, etc. to form a mixed substrate with loam. In summer, it is necessary to properly shade the light, especially in July and August every year under full light and strong light, the chlorophyll of the leaves is damaged, which will lead to the death of young trees.

During the dormant period, it can tolerate low temperatures of -42, has no frost damage, and does not lose leaves when buried by heavy snow. Summer temperatures over 30 slow growth and stop as temperatures continue to rise. In spring and autumn, it is watered in case of drought.

Remember: don't be a diligent gardener and "sweat and water frequently" (too many times and too much water are the main reasons for the failure of potted yews).

Yew grows well in soil with fertile, loose, moist, well-drained soil and high organic matter content, and grows particularly well with organic matter content of more than 3%. Therefore, the bonsai soil must be fertilized, the amount of fertilizer to organic fertilizer per plant and compound fertilizer pound or so, can also be appropriate to apply some farm fertilizer, cake fertilizer (such as cottonseed cake, peanut cake, hemp cake), fertilization should be applied along the wall of the pot as much as possible, and do not approach the roots of yew.

After two years of bonsai planting, the seedlings gradually grow up, the root system is more developed, the original pot can not meet the needs of growth, must be changed to a large pot for cultivation, transplanting and changing pots generally choose the yew dormant period, seize the cloudy day for bonsai transplanting and repotting, at this time the survival rate of transplanting is higher. During the transplanting process, the root system of the young tree must be kept intact and the moisture content of the root hairs, and the root system and the soil should be closely combined when planting. If possible, yew seedlings can be transplanted into the field to grow, and their growth rate will be faster.

Yew branches are tough and soft, not ** after taking the branches, suitable for modeling, can be properly pruned, made into various shapes, and cultivated bonsai.

Maintenance: 1Soil disinfection Before planting, the soil is dug and exposed to the sun, flooded with water, and then disinfected with soil disinfectant.

2.Planting Before planting, it is necessary to lay an anti-inverted net, and lay 3 layers with the hole-to-hole overlapping method, which requires straightening, alignment, and fixation. Immediately after that, the land that has been leveled is watered enough, and it is advisable to knead it with your hands into a ball but not sticky to your hands.

The depth of planting should be shallow, and the principle of not lodging should be done. After the cultivation is completed, water the root water once, to water thoroughly, with a depth of about 30 cm, so that the root system of the plant is in full contact with the soil, and create the most favorable conditions for the growth of the root system as soon as possible.

3.Shade After planting, it is recommended to use 70% to 75% shade net for 7 to 10 days, and pay more attention to the scorching weather, and remove the shade net in the evening of the same day. The next morning, pull a plant and observe the growth of the root tips.

In case of strong winds and scorching sun, even if the plants wilt, as long as the roots in the soil grow vigorously, there is no problem.

4.Management On the second day of cultivation, a full-range spray of fungicides should be carried out on the field, such as chlorothalonil, carbendazim, etc. Controlling the disease during this period allows the plants to grow in a relatively clean environment, and the result is a robust and highly resistant plant.

Keep the soil moist after planting, for example, in the summer the side film should be rolled up to facilitate ventilation. After removing the shade net, apply a thin nitrogen-based compound liquid fertilizer once every 7 days when new roots grow, until the topping enters the seedling stage.

Ventilation, shade, less watering, absolutely OK

Pandas in the plant world: sharing of yew conservation methods.

Like yin and afraid of water, yew seedlings should not be flooded. The ditch should be dug deep to facilitate drainage.
