1. Matrix selection: it is not strict with the soil, has strong adaptability, and can tolerate barren soil. It is better to choose loose and fertile sandy loam with good drainage and slightly acid.
2. Light management: most of them like light and are weak in negative tolerance. If they are in dark environment for a long time, it is easy to cause sparse crown. Therefore, they should be given as much sunlight as possible when breeding, which is conducive to their healthy growth.
3. Water management: the leaves are narrow and the cuticle is developed, with xerogenic structure, so it has strong drought resistance, can tolerate water shortage without damage, can grow in the shallow and stony soil layer of the 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 logging.
4. Temperature management: it is a famous pioneer tree species. It has strong adaptability to the environment temperature. It is cold and heat-resistant. It can thrive in both high and low temperature environments.
1. Propagation method: it can be propagated by sowing or cutting. Among them, the sowing method is to store seeds in the sand in winter to promote germination, cover the grass curtain on the sand pile, pay attention to heat preservation and freeze protection, keep the environment ventilated, and then sow the seeds when there are about half of the cracks in the next year.
2. Transplanting method: its transplanting method is different because of different kinds of seedlings, among which the container seedling with soil lump can protect the root system of the plant from damage during the transplanting process, so the survival rate is higher, while the root system of the bare root seedling is relatively easy to be damaged, so attention should be paid to protect the root system during transplanting..
1. Yellow leaves: if the needles lose water and turn yellow, it is necessary to check whether there is any sign of longicorn parasitism. If it is found, it is necessary to cut down and remove the diseased trees in time to prevent the spread of longicorn and damage the trees.
2. Insect pest: the common insect pests are spider, coir moth, red wax scale insect, etc. once found, it should be sprayed with insecticide in time.
1. Moral: it has a vigorous and magnificent tree, a tall and long life, and a long history and culture. It is regarded as a symbol of firmness, chastity and longevity. It is also called "three friends in the cold" with plum and bamboo. It has the tenacity to overcome adversity and difficulties.
2. Toxicity: it has no toxicity. Pine is generally used as industrial raw material, among which rosin can be used to extract rosin, some seeds and pine needles can also be used as medicine, which is of great practical value.
