Introduction

Since the release of the “Fir Cultivated High Yield and High Yield Forest Standard”, it has been going through 20 years. During this period, the cultivation technology of Chinese fir has been faster. The development of the fast-growing and high-yield timber forest of Chinese fir has the techniques of genetic control, density control, vegetation control, soil maintenance and cultivation mode optimization. A lot of improvements, the original standard has not adapted to the current requirements for the cultivation of fast-growing and high-yield timber forests, so the original standards need to be revised. Fast-growing and high-yield timber forest

1 Scope

This standard specifies the technical measures and growth indicators for the cultivation of fast-growing and high-yield timber forests. This standard applies to state-owned, collective, and individual accepting the high-yield forest of Chinese fir planted by the state.
