Problems solved by technology

However, the existing applications mainly rely on harvesting the roots and stems of wild Lauraceae plants, which not only seriously damages the environment, but also with the reduction of wild resources, the price of raw materials continues to rise, not only the production cost is high, but also the supply of raw materials is difficult to meet industrial production needs

Embodiment 1

[0020] In the early, late or cloudy days of March, select the 1-2 year-old hairy tree pepper with tip side branches, 0.3-0.5 cm in diameter, and use sharp branch scissors in the shade after collection to cut the branches into 20 cm long, with 5 ~ Leafy cuttings with 6 branches. The upper end of the cuttings has 3 to 4 leaves, and the base of the lower end is cut into a horseshoe-like slope at a distance of 1 to 2 cm from the branch node to increase the contact surface with the substrate to facilitate water absorption. The cut surface is smooth and lint-free. The cut cuttings are bundled with 50 branches and tied with ropes. Then, place the base of the cuttings in 100PPM aqueous solution of ABT rooting powder and soak for 1.5 hours with a depth of 3 to 4 cm. Put the soaked cuttings in a clean, moist sand bed. The sand bed is 20 centimeters high and 1.2 meters wide, and there is a 40-centimeter walkway between the sand beds. The sand bed is built in the shade shed, the height...

Embodiment 2

[0023] Repeat embodiment 1, following difference is arranged: cutting adopts lateral branch to grow 20 centimetres, does not have leaf cuttings of 3~6 branches, diameter 0.4~1.0 centimetre. The cutting survival rate of this kind of cuttings is lower than that of cuttings with leaves, but there are more materials for cuttings, so they must be used when multiplying seedlings in large quantities.

Embodiment 3

[0025] Repeat Example 1, with the following differences: the cuttings are cut from the main trunk of the plant to a length of 25 centimeters, 3 branches, and cuttings without leaves with a diameter of 1.0 to 3.0 centimeters. The depth of the liquid medicine at the base is 5 cm, and the cutting depth is 7-8 cm. The cutting survival rate of this kind of cuttings is very high, but the material is limited, the cuttings are relatively thick, and it is difficult to cultivate bag seedlings, so it is suitable for cultivating bare root seedlings.

Abstract

The invention relates to a method for cultivating pepper, wherein it uses the side branch or main tree of pepper; shearing into graft; putting the base of graft into rooting solution; grafting it into sand bed; when most part roots, transplanting the seed into nourishment bag; when seed grows 30cm, planting in field. The invention can reduce cost with wide application.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for artificial propagation of spice plants, in particular to a method for cutting propagation of peppercorns. Background technique [0002] Piper hispidenervum C.DC. belongs to the Piperaceae (Piperaceae) genus (Piper). Shrubs or small trees, generally 4 to 6 meters high, up to 9 meters high. Branches, leaves and infructescence are fragrant. Bark off-white, branches cylindrical, greenish-yellow, smooth, multi-noded, internodes of branches 2-6cm long, internodes swollen, stems of young branches slightly biased, with lenticels; leaves alternate, entire, papery, elliptic, 7-16cm long, 4-8cm wide, apex with pointed tail or acuminate, base with varying sides, semi-heart-shaped; leaf veins 5-7 on each side, main and lateral veins slightly concave above, convex below, Plumber; short petiole, about 0.2-0.5cm, pilose or glabrous; spikes, opposite to leave...
