Quick cultivation method of Rosa multiflora thunb.var.cathayensis

Abstract

The invention discloses a quick cultivation method of Rosa multiflora thunb.var.cathayensis. a rooting powder solution is NAA with the concentration of 300 mg.L<-1>, red-yellow soil serves as a cutting medium, one-year-old stems with leaves serve as cuttings, treatment time is four hours, the cutting substrate which is 8-10 cm thick covers a seedbed, the processed cutting scions are inserted by being punched by a wood stick according to the plant spacing of 15 cm*15 cm, the insertion depth is 1 / 2-2 / 3 of the length of the scions, the soil is sufficiently watered immediately, and the temperature is 20-25 DEG C. The method is high in cutting survival rate and rooting rate and good in quality, and lays a foundation for large-scale seedling raising of Rosa multiflora thunb.var.cathayensis.

Description

technical field

[0001] The invention belongs to the technical field of agriculture and forestry cultivation, and relates to a method for rapidly cultivating roses. Background technique

[0002] Rosa multiflora Thunb.var.cathayensis is a climbing shrub belonging to the family Rosaceae. It is native to the central and southern provinces of my country and has a long history of cultivation. Its color, fragrance and shape are excellent, and it is cold-resistant, drought-resistant, and barren-resistant. It has high ornamental value and garden application potential. It is often widely used in vertical greening of flower racks, flower galleries, walls, and arches. At the same time, Rosa adenoides also has industrial use value and has certain medicinal effects. Therefore, the ecological benefit and economic benefit of the powder group rose are remarkable, and it has great development potential and broad market prospect.

[0003] At present, many scholars and experts at home and ab...

[0030] (1) Experimental design

[0031] The inventive method adopts the L of four factors three levels 9 (3 4 ) Orthogonal experiment design scheme, that is, four main factors that affect the rooting quality of rose cuttings in powder group are used as experimental factors: A (NAA concentration), B (cutting substrate), C (cutting type), D (treatment time). The levels of each factor are: A 1 100mg·L ～1 , A 2 200mg·L ～1 , A 3 300mg·L ～1 ;B 1 For red yellow soil, B 2 For river sand, B 3 For vegetable garden soil; C 1 For the stem segment with terminal bud, C 2 It is a stem segment of one or two years, C 3 It is an annual leafy stem segment; D 1 for 1h, D 2 for 2h, D 3 for 4h.

[0058] experiment procedure

[0059] (1) Preparation of cuttings: Collect annual semi-lignified branches from robust growth, no damage, no pests and diseases of Rosa rosea plants, with a diameter of not less than 1 cm. Cut 12-15cm annual stem cuttings with leaves, keep 2-3 nodes, keep 1-2 axillary buds and half or a small leaf on the buds on the cuttings, cut the upper incision about 1cm away from the buds on the cuttings, and cut it into an obtuse angle , The lower incision is about 1-1.5cm away from the lower part of the lower bud of the cuttings and cut into an acute angled slope. Before cutting, soak both ends of the cuttings with 600-800 times carbendazim dilution solution. After 5-10 minutes, wash 2-3 times with clean water to remove the residual carbendazim on the cuttings, and then use rooting powder solution to clean the cuttings. to process.
