当植物幼年期结束,性细胞形成时,就已经开始具有开花结实的能力。但植物雌雄花形成、发育、枝条性别以及外界环境条件,对雌雄花受粉、枝条性别转化的影响等,都直接关系着植物是否结实和结实量多少的问题。且这些影响和关系又因植物种类不同而开花结实的特性各异。杉木也与其他植物一样有它本身的特性,故为了解杉木种子收获量进行比较正确的产量預測,就必需首先掌握其开花结实的生物学特性,才能使产量預测預报
When the plant juvenile period, the formation of sex cells, it has begun to flowering with strong ability. However, the formation and development of plants and their male and female flowers, the gender of the branches and the external environmental conditions affect the male and female flowers affected by the powder and the gender transformation of the branches, which are directly related to the problem of whether the plants are strong and sturdy. And these effects and relationships vary according to plant species and flowering of different characteristics. Cunninghamia lanceolata, like other plants, has its own characteristics as well. Therefore, in order to make a more accurate prediction of the yield of Cunninghamia lanceolata seeds, it is necessary to first grasp its biological characteristics of flowering and fruiting,
