1、 Curing method

1. Matrix selection: it has no strict requirements on soil, strong adaptability and can resist barren. It is best to choose loose, fertile, good drainage and acidic sandy loam

2. Light management: most of them like light and are weak in negative resistance. If they are in a dark environment for a long time, it is easy to lead to sparse tree crowns. Therefore, when breeding, they should try to give sufficient sunlight, which is conducive to their vigorous growth

3. Water management: it has narrow leaves, developed cuticle and xerophytic structure, so it has strong drought tolerance, can tolerate water shortage without damage, and can grow in a shallow and rocky arid environment. Excessive water content in the soil is unfavorable to its growth. It is necessary to pay attention to drainage and avoid excessive water accumulation and waterlogging

4. Temperature management: it is a famous pioneer tree species with strong adaptability to environmental temperature, cold resistance and heat resistance. It can thrive in both high and low temperature environments

2、 Breeding skills

1. Propagation method: it can be propagated by sowing or cutting. The sowing method is to store seeds in sand to promote germination in winter, cover grass curtains on sand piles, pay attention to keep warm and antifreeze, and keep the environment ventilated. Sowing can be carried out when about half of the seeds are cracked the next year

2. Transplantation method: the transplantation method is different due to different types of seedlings. Because the container seedlings have soil lumps, they can protect the plant root system from damage during the transplantation process, so the survival rate is high, while the root system of bare root seedlings is relatively easy to be damaged. Attention should be paid to protecting the root system during transplantation

3、 Diagnosis and treatment problems

1. Yellowing of leaves: if the needles lose water and turn yellow, be sure to check whether there are signs of longicorn beetle parasitism. Once found, it is necessary to manually cut down and remove the diseased trees in time to prevent the spread of longicorn beetles and harm the trees

2. Insect pests: its more common pests include red spider, big coir moth, red wax scale insect, etc. once found, it should be sprayed with insecticide in time

4、 Other issues

1. Moral: it has vigorous and magnificent tree posture, tall and long-lived tree shape, long history and culture. It is regarded as a symbol of firmness, chastity and longevity. Together with plum and bamboo, it is known as the "three friends of winter". It has the tenacious spirit of bravely overcoming adversity and difficulties

2. Toxicity: it has no toxicity. Pine wood is generally used as industrial raw materials, in which rosin can be used to extract rosin, and some varieties of seeds and pine needles can also be used as medicine, which is of great practical value
