How much is the sweet-scented osmanthus seed per jin? When will the seeds be sown? What are the planting methods?

Sweet-scented osmanthus seeds, that is, the seeds of sweet-scented osmanthus after blooming in autumn. The shape is like a cyan olive and the color is purplish black. How much is its seed per jin? When will the seeds be sown? What are the planting methods? Generally speaking, sweet-scented osmanthus seeds are between 60 and 80, of course, some better varieties may be more expensive. It will mature in March or April. The seeds can be sown from August to September of the current year, or from April to May of the following year.

What are the planting methods of sweet-scented osmanthus?

The sowing and breeding of sweet-scented osmanthus starts with the selection of sweet-scented osmanthus seeds. To choose sweet-scented osmanthus seeds with exquisite quality to sow. The most suitable time for sowing in the north is from May to June when the temperature is 22-24 degrees.

1. After soaking the sweet-scented osmanthus seeds in warm water for 24 hours or cold water for 48 hours, choose the leeward garden with loose drainage to sow in the basin soil with a layer of 2-3 cm fine sand after sowing. Spray water once and cover with glass or other entangled objects (such as straw) Osmanthus seeds should be removed after germinating. Make it breathable. And beware of direct sunlight.

two。 When sweet-scented osmanthus seeds germinate, the soil temperature should be 18-30 degrees. The soil temperature is too low. If the sowing soil is too wet, it will cause the sweet-scented osmanthus seeds to fail.

3. The moisture in the soil is uneven. Occasionally too wet. Accidentally too dry. In addition, the sweet-scented osmanthus seeds have germinated. The soil water content is not enough after the root system has protruded the seed coat. The root system can not absorb abundant water, resulting in root hair drought and abandoning the world, and sweet-scented osmanthus seedlings fail in the soil. At this time, too much water content in the soil will inevitably cause insufficient air content to cause the new root to be unable to breathe. the time is too long, resulting in failure after the abandonment of the world.

4. If the substrate is not suitable for sowing, we should choose fine sand humus soil, non-fertilizer rotten leaf soil, vermiculite, perlite and so on. Permeable, exquisite drainage matrix. The dense crossing of sowing substrate is too high. Sweet-scented osmanthus seeds are so sticky that it is difficult to unearth after germination. Too long time will infarct and abandon the world.

5. Sweet-scented osmanthus seeds placed too long, also known as the next year seeds Chen sweet-scented osmanthus seeds. The seeds of Osmanthus fragrans have entered the dormant period after drying. In reality, they are still simulating the consumption of their own stored nutrients in a slow psychological hook. Water can be used up and can no longer germinate.

6. The management work after seed germination should keep up in time in order to cultivate robust seedlings. The growth and development of seedlings should be done well in the specific operation:

(1) uncover the grass and shade: when the seeds are germinated and unearthed, the grass should be properly uncovered on a cloudy day or in the evening.

(2) loosening soil and weeding: loosening soil should be carried out in time, with a depth of 2-3 cm, which should be shallow rather than deep, so as to prevent root injury.

(3) Interseedling and supplementary seedling: sweet-scented osmanthus seedlings are more shade-tolerant and grow slowly, so it is generally not necessary to transplant and replenish seedlings properly. Do not damage the root system of the retained seedling when moving the seedling, and irrigation should be carried out after the seedling transfer, so that the seedling root is closely combined with the soil.

(4) Irrigation, drainage and fertilization: drought resistance and seedling protection must be paid attention to in summer and autumn, and irrigation should be carried out in the morning or evening.

(5) Prevention and control of diseases and insect pests: Brown spot and vertical blight were easy to occur in the nursery of continuous cropping of sweet-scented osmanthus, resulting in a large number of withered and yellow leaves, or root neck and root cortex rot, resulting in the death of the whole plant. At the same time, aphids are also easy to occur in the seedling stage.

(6) timely transplanting: the annual seedling height of Osmanthus fragrans is 20cm and 30cm, and it is transplanted in the early spring of the following year. When the height of 2-year-old seedlings is about 60 cm and that of 3-year-old seedlings is about 1 m, retransplantation is required. When it is used as a shade tree or trunk road tree, it is generally required to be cultivated for 8 years, with a height of 2 meters and a diameter of 8 centimeters, which is beneficial to the maintenance and management after planting.
