Problems solved by technology

At present, the research on Eucalyptus eucalyptus mainly focuses on the use of Eucalyptus eucalyptus wood and branches and leaves or the extraction of active components from branches and leaves. There are very few studies on the planting and seedling cultivation of Eucalyptus eucalyptus. The demand for Eucalyptus eucalyptus seedlings is increasing, but the current cultivation of Eucalyptus eucalyptus seedlings generally has the phenomenon of low emergence rate and poor economic benefits, which makes it difficult to meet the needs of the market

Embodiment 1

[0028] The method for raising seedlings of Eucalyptus macrophylla seeds includes seed selection, seed dormancy treatment, seedbed selection and treatment, sowing and seedling management, and the specific steps are as follows:

[0029] (1) Seed selection: Pick Eucalyptus grandiflorum fruits at the maturity stage of seeds from August to October and spread them for 3 days. After the seeds fall off naturally, collect the fallen seeds and store them in a dark place.

[0030] (2) Seed breakage treatment: the seeds were stored at 3°C ​​for 48 hours, then taken out, and immediately soaked in warm water at 45°C for 6 hours at a constant temperature.

[0031] (3) Sowing: choose a substrate without perlite to be exposed and sterilized as a breeding substrate, and a transparent disposable plastic box with a lid is used as the seeding box (the bottom length is 13.2cm, the bottom width is 4cm, and the height is 5cm). First add a layer of substrate to the seeding box and spread it evenly, wi...
