Cultivation method for improving survival rate of keteleeria evelyniana seeds

Abstract

The invention discloses a cultivation method for increasing the survival rate of keteleeria yunnanensis seeds. The cultivation method comprises the following steps of preparing a seedling planting bag, specifically, filling a 8 cm*12 cm nutrition bag with pretreated red subsoil, filling the nutrition bag with the red subsoil until the red subsoil is 2 cm away from a bag opening at the first time, conducting thorough watering, and then enabling the nutrition bag to be full of the red subsoil for later use; conducting seed preparation, specifically, removing impurities and wormy seeds from the keteleeria yunnanensis seeds subjected to earlier-stage treatment, soaking the seeds in a 0.3% potassium permanganate solution for 2 hours, soaking the seeds with cold boiled water, and fishing out the seeds for later use; conducting dibbling, specifically, dibbling one seed soaked in the potassium permanganate solution in the step 2 into the nutrition bag with seed wings at the upper portion, covering the seed with a substrate with the thickness of 1 cm-2 cm, preferably covering the seed wings, and conducting thorough watering after dibbling; and conducting management, specifically, mainly performing water management to ensure that the substrate is not dry, and performing full-illumination seedling culture after budding. The invention relates to the technical field of keteleeria yunnanensis cultivation, in particular to the cultivation method for increasing the survival rate of the keteleeria yunnanensis seeds, a one-stage seedling raising manner is adopted, the survival rate can reach 95%, and the purpose of saving cost is achieved.

Description

technical field [0001] The invention relates to the technical field of the cultivation of Chinese fir yunnanensis, in particular to a cultivation method for improving the survival rate of Chinese fir yunnanensis seeds. Background technique [0002] The wood of Yunnan oil fir is durable and used for construction and so on. The wood is rich in resin, and the seeds contain 30% oil, which can be used in the soap making industry. [0003] Generally, two-stage seedling cultivation is adopted for the seed propagation of Chinese fir, but because the root system of Chinese fir is fleshy, it is not conducive to survival after transplanting. Contents of the invention [0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a cultivation method for improving the seed survival rate of Chinese fir yunnanensis. By adopting a one-stage seedling cultivation method, the survival rate can reach 95%, and the purpose of cost sa...
