Embodiment 1

[0026] 1. Materials and methods

[0027] (1) Experimental design

[0028] In this experiment, four factors and three levels of L 9 (3 4 ) Orthogonal experiment design scheme (see Table 1), that is, the four main factors that affect the rooting quality of Golden Streak pilosa cutting propagation as experimental factors: A (GA3 concentration), B (cutting substrate), C (cutting type) , D (processing time). The levels of each factor are: A 1 50mg·L ～1 , A 2 100mg·L ～1 , A 3 200mg·L ～1 ;B 1 For red loam, B 2 For river sand, B 3 For vegetable garden soil; C 1 For the stem segment with terminal bud, C 2 For leafy stem segment, C 3 It is a leafless stem segment; D 1 for 0.5h, D 2 for 1h, D 3 for 2h.

Abstract

The invention discloses a cutting propagation method of antenoron neofiliforme. A rooting powder solution is prepared from GA3 with the concentration of 100 / mg.L<-1> and NAA with the concentration of 100 / mg.L<-1> at the ratio of 2 to 1; a cutting medium is prepared from red soil and river sand at the volume ratio of 3 to 1; a cutting slip type is a stem with an apical bud; treatment time is 0.5h; a rooting effect of cutting propagation of the antenoron neofiliforme is the best, and the cutting survival rate can reach 99.98 percent. The method disclosed by the invention has the advantages of early rooting time, rapid growth speed, short propagation period, high survival rate and the like; the problem of a conventional cutting technology that the survival rate is low is solved, and the cutting propagation method is low-cost, is simple to operate, and is easily popularized and applied in a large area.

Description

technical field [0001] The invention belongs to the technical field of golden-thread grass cultivation and relates to a method for cutting and propagating golden-thread grass. Background technique [0002] Herba Antenoronis Neofiliformis (Herba Antenoronis Neofiliformis), also known as Chongyang willow, crab shell grass, Polygonum hairy, white verbiformis, etc., is a perennial herbaceous plant of the Polygonaceae family. Common in the wild state, with a small amount of cultivation, it is distributed in southern Gansu, southern Shaanxi, East China, Central China, South China and Southwest China. As a perennial herb, golden thread grass has red flowers and buds, and the buds will not fall after the flowers wither. It is of great ornamental value. The plant height is 50-100cm. It is born in the damp area of ​​the hillside, and it is resistant to barrenness and has strong adaptability. , extensive management, is an excellent understory ground cover. At the same time, golden th...
