Cultivation method for sweet scented osmanthus trees

Abstract

The invention discloses a cultivation method for sweet scented osmanthus trees. The method comprises the following steps: (A) seed pretreatment; (B) substrate preparation; (C) seedbed levelling; (D) sowing and earthing; (E) nursery management; (F) sapling transplantation; and (G) sapling tending, management and protection. When the method disclosed by an embodiment of the invention is used for cultivation of the sweet scented osmanthus trees, a germination rate of seeds of the sweet-scented osmanthus trees is 97.3%, germination potential is 96.2%, and a survival rate is as high as 99.1% after30 days of germination; and 3 months after sowing is performed, the quantity of sweet-scented osmanthus tree seedlings with a height of 90%-110% of an average seedling accounts for 92.7% of the quantity of total sweet-scented osmanthus tree seedlings, and the quantity of sweet-scented osmanthus tree seedlings with a ground diameter of 90%-110% of an average ground diameter accounts for 97.8% of the quantity of the total sweet-scented osmanthus tree seedlings.

Description

technical field [0001] The invention relates to the technical field of agriculture and forestry seedling cultivation. More specifically, relate to a kind of sweet-scented osmanthus tree cultivation method. Background technique [0002] Osmanthus fragrans has been widely cultivated in many places in China. The propagation of sweet-scented osmanthus mostly adopts the method of cutting propagation. This is because the seeds of sweet-scented osmanthus have a dormancy period, and the germination rate of sowing and propagation is low, and the survival rate after germination and the survival rate of transplanting are all relatively low, which limits the cultivation by sowing. Large-scale propagation of sweet-scented osmanthus trees. [0003] In the prior art, usually after collecting the osmanthus tree seeds every year, stratification or sand storage is until March of the second year, and then the seeds can be sown after being processed; this method is more complicated on the one...

The propagation of sweet-scented osmanthus mostly adopts the method of cutting propagation. This is because the seeds of sweet-scented osmanthus have a dormancy period, and the germination rate of sowing and propagation is low, and the survival rate after germination and the survival rate of transplanting are all relatively low, which limits the cultivation of osmanthus by sowing. Large-scale propagation of sweet-scented osmanthus trees

[0003] In the prior art, usually after collecting the osmanthus tree seeds every year, stratification or sand storage to March of the second year can be sown after the seeds are processed; The survival rate of teething and transplanting is still relatively low, so it is not suitable for large-scale promotion and reproduction in forestry
