八角是我区贵重的经济林木,果实及油畅销国内外。但当前仍采用实生苗繁殖,管理粗放,大部分树冠稀疏、直立、高大、生长慢、结果迟、收益见效慢、种性退化变异大。据调查,一般8—15年才试花结果,30—40年后进入丰产期,且不稳产,大小年结果悬殊,单产低,采摘困难。为解决上述存在问题,我们于1976—1981年分别在本县滩营果场、那良公社那旺

Star anise is my area of ​​economic timber, fruit and oil popular at home and abroad. However, seedlings are still used to reproduce, extensive management, most canopy sparse, upright, tall, slow growth, the results of late, the proceeds of the slow, large variation of species degeneration. According to the survey, the results of flowers are generally tested in 8-15 years, and they enter the high yield period after 30-40 years with unstable yield. The result of annual size is poor, yield is low, and picking is difficult. In order to solve the above problems, we in 1976-1981 beach camp in the county, that good commune that Wang
