Problems solved by technology

The growth of sweet-scented osmanthus is very slow, and the survival rate of cuttings is not high, mainly because the cuttings of sweet-scented osmanthus trees are difficult to root when cutting, and the cuttings of existing sweet-scented osmanthus trees are relatively small, and the speed of coming out of the nursery is slow.

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the examples. The following examples are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0013] A closed cutting seedling raising method for osmanthus fragrans, the method comprising the following steps:

[0014] (1) Nursery selection: Choose sandy loam or light loam with good drainage. If the soil is too sticky, mix it with sand to adjust the soil texture. Spray pesticides for soil disinfection when making beds. The slotting bed should be high to ensure smooth drainage;

[0015] (2) Build a closed space: use the shade shed to cover the plastic shed for closed seedling cultivation. Specifically, the slotting bed has a width of 1.10 meters and is inserted in a bow shape with bamboo pieces sharpened at both ends. The length from the bed surface to the bow top is 0.5 The two sides of the plastic canopy are pressed with mud, and t...

Abstract

The invention discloses an osmanthus sealed cutting seedling growing method. The method comprises the following steps of (1) selecting a nursery, i.e. selecting sand soil or light soil with good drainage; (2) building a sealed space, i.e. adopting the way that a shadehouse sleeves a plastic house to grow seedlings in the sealing environment; (3) selecting and treating cutting wood, i.e. selecting tender shoots which are grown in the year to be subjected to cutting, 1 to 2 months before picking spikes, applying an active fertilizer for 2 to 3 times to promote growth of the tender shoots, and before cutting, soaking the tender shoots in 500PPM of naphthyl acetic acid; (4) performing cutting to grow the seedlings, i.e. from the middle ten days of May to the last ten days of June, or from the middle ten days of August to the last ten days of September, obliquely inserting cutting slips into a cutting bed, keeping leaves upward, and inserting one second of the cutting slips into soil, wherein the planting spacing is 6*10cm, and 200 strains are inserted every square meter; (5) performing management after cutting, i.e. after cutting, timely spraying water, and spraying 500 to 1,000 times of Tuzet for one time every one month. The root-growing speed is high, the root-growing rate is high, the survival rate is high, the cuttings for cutting are large, seedlings can be relatively quickly taken out of the nursery, and the economic benefit is improved.

Description

Technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a closed cutting seedling raising method of osmanthus. Background technique [0002] Osmanthus fragrans, also known as Melilotus officinalis, is an evergreen tree of Melilotus family. Osmanthus fragrans is native to the Shandong section of the Himalayas in southwestern China, as well as in India and Nepal. It has a cultivation history of more than 2500 years in China, and it is planted in large numbers in open fields south of the Yellow River and southwestern Guangdong. Osmanthus fragrans is a long-day plant, it likes to grow in a place with plenty of sunlight, thick soil and good drainage. The soil should be slightly acidic, with a pH of 5.5 to 6.5. Avoid alkaline soil, fear of standing water and soot. Potted plants are needed in the north, and low temperature greenhouses will survive the winter. Temperatures around 0°C will not be harmful to potted osmanthus....
