Embodiment 1

[0027] Jasmine leafy twig cutting propagation method of the present invention, its concrete process steps are as follows:

[0028] Seedbed preparation: establish a seedbed 4 in the breeding site, lay vermiculite cutting substrate 1 on the seedbed 4, and spray the seedbed 4 and cutting substrate 1 with 0.1% potassium permanganate solution for disinfection.

[0029] Preparation of cuttings: From mid-to-late June to early July, cut the semi-lignified branches with leaves of the year from the single-lobe jasmine female parent, soak and rinse in clean water, and cut each pair of jasmine according to the natural growth of stems and leaves. The leaf is a section, cut horizontally at 1 cm above the opposite leaf, and cut off 2 / 3 of the leaf area of ​​each leaf to make a cutting of 5 cm in length. For the selection of the female parent, plants that are robust and free of diseases and insect pests should be selected. In Xinjiang, from mid-to-late June to early July, there are abundant ...

Embodiment 2

[0036] Jasmine leafy twig cutting propagation method of the present invention, its concrete process steps are as follows:

[0037] Seedbed preparation: establish a seedbed in the breeding site, lay perlite cutting substrate on the seedbed, spray the seedbed and cutting substrate with 50% carbendazim 1000 times solution, and then seal it with a film for 2 days.

[0038] Preparation of cuttings: From mid-to-late June to early July, cut the semi-lignified branches with leaves of the year from the double-lobe jasmine female parent, soak and rinse in clean water, and cut each pair of jasmine according to the natural growth of stems and leaves. The leaf is a section, cut horizontally at 1.5cm above the opposite leaf, and cut off 2 / 3 of the leaf area of ​​each leaf to make a cutting with a length of 6cm.

[0039] Cutting cuttings: Carry out cuttings on the cutting substrate by the straight insertion method, 6 cuttings are a unit, the distance between cuttings is 1.5cm, the depth of c...

Embodiment 3

[0044] Jasmine leafy twig cutting propagation method of the present invention, its concrete process steps are as follows:

[0045] Seedbed preparation: establish a seedbed in the breeding site, lay a self-made cutting substrate on the seedbed,

[0046] The cutting substrate is a mixed substrate, and the mixed substrate is mixed with soil, river sand, decomposed sheep manure and sawdust at a volume ratio of 15:2:1:1 above the plowing layer 10cm to obtain a preliminary mixture, and then add the total volume of the preliminary mixture 1 / 6 of pine needle soil mixed. Pine coniferous soil is composed of rotten pine needles and residual branches, which is relatively acidic and suitable for the growth of acid-loving flowers such as jasmine. Seedbeds and cutting substrates are disinfected with sulfur powder, specifically adding 500-800g of sulfur powder per cubic meter of substrate and stirring evenly.

[0047] Preparation of cuttings: From mid-to-late June to early July, cut the sem...

Abstract

Disclosed is a cutting propagation method of a leaf-borne jasmine twig. The method includes the following steps that (1) a seedbed is built, a cutting medium is spread on the seedbed, and the seedbed and the cutting medium are disinfected; (2) a leaf-borne twig is cut down from a jasmine female parent, each pair of opposite leaves serves as a section, the twig is straightly snipped at a position 1 to 2 cm upwards away from the opposite leaves, and 2 / 3 of the leaf area of each leaf is snipped to form cutting slips which are 5 to 8cm in length; (3) the cuttage is performed on the cutting medium, each 5 to 10 cutting slips form a cutting slip unit, the intervals among the cutting slips are 1 to 2cm, and the depths of the cutting slips are 1 to 2cm; (4) light transmittable covering bottles are covered on the cutting slip units, and bottle openings are embedded into the cutting medium; (5) the cutting medium is watered thoroughly after cuttage to enter into a post-cuttage management stage; and (6) the light transmittable covering bottles are removed after new leaves are grown out, and the transplantation is performed after 6 to 8 days. By means of the cutting propagation method of the leaf-borne jasmine twig, rapid and mass propagation is achieved, and costs for culturing seedlings are low. Besides, the rooting percentage can be improved, and the survival rate of transplanted cutting seedlings reaches to 70%.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, and more particularly relates to a method for cutting propagation of jasmine leafy shoots. Background technique [0002] Jasmine (Jasminum Sambac Ait.) belongs to Oleaceae and Jasminum. Native to Iran near the Persian Gulf in India. Jasmine was introduced to my country from West Asia as early as 1700 years ago, and was first introduced in Yunnan. Single-petal jasmine is a kind of jasmine. The plant is short, 70-90cm high, with thin stems and branches, in the shape of a vine, so it is called "Fujimoto jasmine". Its rich aroma is unmatched by other jasmine varieties. The order of the aroma of the three jasmine varieties is single-petal jasmine > double-petal jasmine > multi-petal jasmine. "One flower can smell the fragrance of a room" jasmine, from June to October Both can bloom and have a long flowering period. It is the most common aromatic potted plant in the north. [0003...
