Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces LY/T 1528-1999 "Sweet pine fast-growing and high-yield timber forest", this standard is compared with LY/T 1528-1999, mainly The technical content changes as follows. --- Re-division of the cultivation area. --- Adjusted the growth index and the rotation period according to different cultivation areas, and increased the yield index. --- Major modifications have been made to the cultivation techniques (afforestation density, land preparation, thinning, etc.). --- Increased the content of the construction and management of high-yield forest projects. This standard was proposed and revised by the National Afforestation Standardization Technical Committee. This standard is drafted by. Hubei Academy of Forestry, Hubei Province Fast-growing and High-yield Forest Engineering Technology Research Center, Jingmen, Hubei Province City State-owned Pengchang Forest Farm, Huanggang Normal College. The main drafters of this standard. Xu Yezhou, Du Yeyun, Du Chaoqun, Li Junzhang, Yang Daigui, Wu Hao, Huang Guowei, Fang Yuanping. Technical regulations for cultivation of fast-growing and high-yield forest of Pinus elliottii

3 Cultivation area division

3.1 Division of cultivation areas According to China's horizontal zonal climatic boundary and the cultivation conditions of slash pine in different areas and their growth differences, the national wetland pine cultivation It is divided into three cultivation areas. South Subtropical, Central Subtropical and North Subtropical. See Table 1. Table 1 Classification of climatic zones for rapid growth and high yield of Pinus elliottii Climatic zone South subtropical cultivation area Guangdong, Central and Southern Guangxi, Fujian Southern North latitude 21 ° ~ 24 °, annual average temperature 21 ° C ~ 22 ° C, daily average temperature 12 ° C ~ 14 ° C, absolute minimum temperature of 2.1 ° C, annual precipitation of 1100mm ~.2000mm Central subtropical cultivation area Hunan, Jiangxi, Zhejiang, Sichuan Basin South Central, Guangdong, Guangxi, Anhui South, central and northern Fujian North latitude 25 ° ~ 30 °, annual average temperature 16 ° C ~ 20 ° C, daily average temperature 3.5 ° C ~ 9.5°C, absolute minimum temperature -12°C, annual precipitation above 1200mm North subtropical cultivation area Hubei, southern Henan, Anhui Southern and southern Jiangsu North latitude 31 ° ~ 33 °, annual average temperature 15 ° C ~ 17 ° C, daily average temperature 2.5 ° C ~ 6 ° C, absolute minimum temperature -16.5 ° C, annual precipitation of about 1000 mm Based on the division of cultivated climatic zones, according to the site and climate of each province (region) and the correlation with the growth of Pinus elliottii, The three types of cultivation areas and five cultivation sub-areas should be divided across zones, as shown in Table 2. ......
