Liquidambar formosa tall and beautiful, dense branches and leaves, rapid growth, deep root roots, root system developed, resistant to drought, thin, adaptability and vitality similar to masson pine, is a pioneer species. Hi light, can also be shade-resistant, anti-cold. Vertically below 1000m slopes, valleys, and sides, often mixed with masson pine, mussels and other species. Appropriate to the average annual temperature of 15-18 °C, the absolute minimum temperature of not less than -10 °C.

1, planting time: in late December after the seedlings fall to the next year in mid-February before the leaves can be carried out. It is advisable to choose the deep, fertile, moist valley, or the lower part of the slope or the middle part of the earth, and also to pioneer the afforestation on the site.
2. Afforestation density: Plant spacing 54m, 33 acres.
3, seedlings requirements: 2 years old, seedling height 80-100cm, ground diameter> 1cm.
4, open pond standards: planting points 6060cm, depth of not less than 40cm.
5, planting requirements: moisturizing soil planting, covered with firewood covered with shading.
Second, the annual management of tending management: Planting the nursery 2 times that year, it is best to fertilize 1 times, mainly farmyard manure.

III. Prevention and control of important diseases and pests
1, seedling stem rot: generally occurs after the rainy season. It is necessary to strengthen cultivation and management to eliminate accumulated water; during the high-temperature and dry-time period, inter-row grassing and irrigation and drought relief should be carried out to reduce ground temperature;
2. Maple silkworm, yellow leafless moth and chafer, etc. Control methods: The fleas can be removed from June to July and sprayed with 90% trichlorfon or 800 times the marathon during the larval colony. The adult beetle can be sprayed with 500 times liquid of trichlorfon or marathon.
