Cultivation and maintenance management of pine trees, methods and precautions for the cultivation of

1.Watering.

Pine trees are very drought-tolerant plants, so you should not water them too often and avoid standing water. You can water every 3-4 days every day, and control the amount of watering reasonably. Watering should be stopped when the temperature is low in winter. In the case of high temperature in summer, it can be watered once every 1-2 days.

2.Illumination.

Pine trees like sunlight, suitable for raising in a sunny place in the courtyard, indoor breeding needs to be placed on the balcony or windowsill to the sun, can accept all-day light, should not accept sun exposure, summer can be placed in the semi-shade maintenance.

3.Fertilize.

Pine trees do not require much fertility, but sufficient fertility can promote more vigorous growth. During the growth period, you can fertilize once in 15-20 days, and it is best to choose thin cake fertilizer water, and fertilization should be stopped in winter.

4.Potting.

Before potting pine trees, the root system needs to be pruned, the old soil at the roots of the plant should be removed 1 3, the root mass should not be scattered, the rotten roots, rotten roots, and dead roots should be cut off, and they should be soaked in the rooting water solution for 5-10 minutes, and placed in a cool place to dry. Prepare humus soil, garden soil, and river sand, according to 6:3:

Mix the ratio of 1 evenly as the culture soil, choose the appropriate size of the pot, put a tile on the bottom of the pot, and spread a layer of culture soil. Put the treated plants into a pot and straighten them, continue to fill the culture soil, compact the soil with a flower shovel, and water to keep the soil moist. Then put it in the indoor astigmatism place for maintenance, slow the seedlings for 10-20 days, and then normal maintenance and management.

1. Substrate selection: its requirements for soil are not strict, the adaptability is strong, and it can tolerate barrenness, so it is best to choose loose and fertile sandy loam with good drainage and acidity.

2. Light management: most of them like light, weak negative resistance, if it is in a dark environment for a long time, it is easy to lead to sparse crowns, so it should be given full sunlight when breeding, which is conducive to its strong growth.

3. Water management: its leaves are narrow and the cuticle is developed, with a xerophytic structure, so it has strong drought tolerance, can tolerate water shortage without injury, and can grow in a shallow and stony arid environment, too much water content in the soil is not conducive to its growth, it is necessary to pay attention to drainage, avoid water and waterlogging.

4. Temperature management: It is a well-known pioneer tree species, which has strong adaptability to environmental temperature, is cold-resistant and heat-resistant, and can thrive in both high and low temperature environments.

1. Propagation method: It can be propagated by sowing method or cuttings. Among them, the sowing method is to promote the germination of seeds in the sand in winter, cover the grass curtain on the sand pile to keep the shed, pay attention to keeping warm and anti-freezing, keep the environment ventilated, and sow when the seeds have about half of the cracks in the next year.

2. Transplantation method: its transplantation method is different because of different seedling species, among which the container seedling can protect the root system of the plant from being damaged during the transplantation process due to the mound, so the survival rate is higher, and the root system of the bare root seedling is relatively easy to be damaged, and it is necessary to pay attention to protecting the root system when transplanting.

1. Yellowing of leaves: If the needles are dehydrated and yellowed, we must pay attention to check whether there are signs of parasitism of the beetle, and once it is found, it is necessary to manually cut down and remove the diseased trees in time to prevent the spread of the beetle and harm the trees.

2. Pests: Its more common insect pests include red spiders, large moths, red wax scale insects, etc., once found, they should be sprayed with insecticides in time.

1. Meaning: Its tree posture is vigorous and magnificent, the tree shape is tall and long-lived, with a long history and culture, it is regarded as a symbol of firmness, chastity and longevity, and plum, bamboo and called "three friends of the year", with the courage to overcome adversity and difficulties of the tenacious spirit.

2. Toxicity: it is not toxic, pine is generally used as an industrial raw material, of which pine resin can be used to extract rosin town, and some varieties of seeds and pine needles can also be used as medicine, which is of great practical value.

1. Planting time. Pine trees are usually planted in March-April, which can be earlier or later depending on the local climate. The reason why spring was chosen is because the climate is suitable at this time, the growth rate of the plants is relatively fast, and it is conducive to rooting and germination after sowing.

If it is selected in the high or low temperature season, it will often affect the future growth of the plant.

2. Seed selection and germination usually collect pine seeds from August to October, dry them after picking, and then put them in a dry place for preservation, so as to avoid mildew and deterioration. Before preparing for sowing, the seeds need to be soaked in warm water at a temperature of about 40, and then stored in the sand to keep their humidity at about 60%, so that they can germinate quickly.

3. Level the land. Planting pine trees must be carried out in a deep, fertile and loose place, the flatter the terrain, the better, and good drainage is very helpful for the growth of plants. In order to ensure its health, it is usually necessary to disinfect the soil and at the same time apply a little fertilizer to the soil to provide it with nutrients.

4. Sowing seedlings. The pine seeds are buried in the soil, properly watered, usually after 25-30 days can be unearthed, and wait another 15 days for their shells to fall off, during which it is necessary to prevent the invasion of birds and beasts, so as not to destroy the seedlings. After the seedlings grow, they should be properly shaded, and when they grow up, they can be supplemented with a little fertilizer.
