How to plant osmanthus seeds for high survival rate
Main content guide: This article shares some small experiences on how to plant osmanthus seeds for high survival rate and the key techniques of osmanthus seed planting. Next, the editor of the website will introduce to the netizens.
The picking time for osmanthus seeds is generally from March to May, and the specific time may vary slightly depending on the geographical location and climatic conditions. When the fruit skin turns black, it can be picked. After picking, the seeds need to be processed because osmanthus seeds have the physiological post-maturation characteristic and need to go through a period of sand storage after picking to fully mature.
Storage methods:
Cleaning: Put the picked osmanthus seeds in water, clean the fruit skin and impurities.
Drying in the shade: Place the cleaned seeds in a well-ventilated and shady place to dry, avoiding direct sunlight to prevent the seeds from losing water and shrinking.
Sand storage: Put the dried seeds in a sand storage container, and the sand storage temperature should be maintained at about 5℃. During sand storage, it is necessary to check regularly to prevent mildew and pest damage.
Sowing technology:
Pre-treatment before sowing: Soak the seeds after sand storage in warm water at about 50℃ for 4 hours, then remove and drain.
Sowing: Choose suitable soil and sowing time, generally in October autumn sowing or the following spring. The sowing amount per mu is about 20 kilograms, which can produce 25,000 to 30,000 seedlings.
Management: After the seeds germinate, it is necessary to remove the grass and shade in time, and avoid damaging the roots when loosening the soil. After reaching a certain standard, transplantation should be carried out.
In summary, the picking, storage, and sowing techniques of osmanthus seeds need to be strictly mastered to ensure the germination rate of the seeds and the growth of the seedlings. The seeds should be treated before sowing, sand storage method should be used during storage, and suitable time and soil conditions should be chosen for sowing. After sowing, management should be strengthened to promote the growth of seedlings.
