Introduction
Pinusyunnanensis Franch. is an evergreen tree species of the genus Pinaceae, distributed in the north latitude 23 ° ~ 30 °, east longitude 96 ° ~
Between 108°, it is concentrated in the high mountains with an altitude of 1600m~2800m. It is very light, deep rooted, developed with main and lateral roots, resistant to drought and thinness.
Natural renewal is good under all light. Yunnan pine is a fast-growing afforestation tree species in the five southwestern provinces with a tree height of 40m and a DBH of 1m. Yunnan
The pine is widely distributed, with Yunnan as the center, east to Guizhou Bijie, Shuicheng and western Guangxi Baise, north to southwest Sichuan Dadu River, Luding and
It is south of Tianquan, west and the southeast of Tibet, and south to the south of Yunnan, Jingdong, Yuanyang, Pingbian and Maguan. Especially in Yunnan Province
The cloth area is the widest, and its area and forest stock volume both occupy the first place. It is a pioneer species of barren mountain afforestation, economic, social and ecological to the distribution area.
Benefits play an important role. To standardize afforestation technology, establish and improve the technical responsibility system, and actively promote the application of new scientific and technological achievements and advanced
This cultivation standard has been developed to improve the yield and quality of Yunnan pine fast-growing and high-yield forests. In the process of formulation,
The technical standards and procedures are formulated in conjunction with the actual and recent developments of Yunnan pine species.
Yunnan Songshengshengfeng Forest
1 Scope
This standard stipulates the technical measures for seedling, afforestation, tending management, harvesting and renewal, etc. adopted by Yunnan Songshengshengfeng Forest.
Growth indicator requirements.

3 Suitability of afforestation
3.1 Site type selection
According to the yield and quality of Yunnan pine forest in the distribution area, eight site types suitable for the construction of Yunnan pine fast-growing and high-yield forest were selected and divided into
2 levels. (1) Optimum area. the type of purple soil in the middle of the shady slope of Zhongshan, the type of red soil in the middle of the shady slope, the volcanic ash in the middle thick layer
Site type; (2) Appropriate zone. the type of yellow-red soil in the thick slope of the shady slope, the red soil site type in the middle slope of the sunny slope, and the yellow-red soil site in the middle slope of the sunny slope
Type, medium-thick layer purple soil site type of Zhongshan Yangpo, and upper-thick layer yellow-red soil site type. See Appendix A for the optimum location characteristics.
See Appendix B for the characteristics of the site.
3.2 Climate factor selection
The altitude of Yunnan Songshengsheng high-yield forest cultivation area is 1400m~2500m, and the climate is mild throughout the year, with no heat and cold. The annual average temperature
13°C~19°C, the average temperature of the hottest month is 20°C~21°C, the average temperature of the coldest month is 7°C~9°C, and the accumulated temperature of ≥10°C is
4000 ° C ~ 5500 ° C, annual rainfall of 800mm ~ 1200mm, relative humidity of 60% ~ 80%. The soil is purple soil or red loam soil.
The pH is 4.5~6.0.
4 Cultivation purposes and high yield indicators
4.1 Purpose of cultivation
The purpose of constructing Yunnan pine fast-growing and high-yield forest is to cultivate forests with medium and large-diameter timber as the main forest, for buildings, pillars, furniture and sawn timber.
Provide materials.
4.2 Afforestation survival rate and preservation rate
The survival rate of afforestation in the current year should reach more than 95% of the number of designed afforestation plants, and the preservation rate in the second year is over 90%.
