对侧柏单株产果量的 1 5年测定结果表明 ,1 0～ 2 4龄的侧柏单株年产果量变幅在1 .1 0～ 2 .6 0 kg之间 ,平均产果量为 2 .1 kg,球果平均出种率 1 2 .85 % ,单株年产干种子 0 .2 7kg。侧柏植株结实有大年和小年 ,间隔期一般为 1～ 2年 ,但株间结实大小年出现的时间并不一致 ,多数植株结实大年则为丰年 ,反之则为欠年。结实量与球果大小及种子千粒质量呈负相关关系 ,结实量越大 ,球果越小 ,种子千粒质量越轻。结实量与植株生长量有一定关系 ,生长好的植株结实较多 ,生长差的植株结实较少 The results of 15 years on the yield per plant of Arborvitae showed that the annual yield of Arborvitae from 10 to 24 years old ranged from 1.1 to 2.06 kg and the average fruit yield The average output of cones was 12.85%. The annual output of dry seeds per plant was 0.27 kg. Oriental arborvitae plants have large and small annual, the interval is generally 1 to 2 years, but between the size of the year appears inconsistent, most of the plants are good for the New Year harvest years, otherwise the year. There was a negative correlation between the seed yield and the size of the cones and the quality of 1000 seeds. The greater the seed setting, the smaller the cones, the lighter the seed quality. There is a certain relationship between the amount of growth and the amount of plant growth, growing good plants more stubborn, poor growth of plants less sturdy
