Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009 "Standardization Work Guide Part 1. Standard Structure and Compilation".

This standard is proposed and managed by the Construction and Management Office of the Fast-growing and High-yield Timber Forest Base of the State Forestry Administration.

This standard was drafted. Yunnan Forestry Academy, State Forestry Administration Fast-growing and high-yield timber forest base construction project management office.

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.
