Problems solved by technology

[0002] Fragrance ( EdgeworthiachrysanthaLind1 ) is a perennial shrub belonging to the family Daphneaceae, also known as Sanya, Tanchun, knotted flower, knotted tree, Huang Ruixiang, home incense, hi flower, dream winter flower, lotus bark, and pimple bark tree, because the branches have There are three divisions of power, so it is named "Sanya"; Jiexiang is native to China, Japan and other places, and it is distributed in all provinces and regions from Henan and Shaanxi in the north to the south of the Yangtze River Basin in China; the fibers of Jiexiang bark are fine and Glossy, in addition to being used as a raw material for high-grade handmade paper, it can also be used as a raw material for banknote paper. The leaves can be used as green fertilizers. The flowers are called "Menghua" and are also used as traditional Chinese medicine. It is beautiful and should be planted in gardens or potted plants for ornamental purposes; the conventional propagation of zixiang includes seed sowing and branch propagation, etc., and seed sowing and propagation methods cannot maintain the original excellent characteristics of fine varieties; although branch propagation can maintain the genetic quality of the mother plant, The number of shoots at the roots of seedlings is limited, and it is difficult to dig out, which limits the large-scale reproduction and production of A. japonica; the hard branch cuttings of A. japonica have a high survival rate, are easy to operate, and have low propagation costs; no relevant reports have been found in China through literature search.

Embodiment 1

[0015] From mid-October to late October, remove the terminal inflorescences of the branches to promote the thick growth of the spikes; in mid-December, select the middle and lower parts of the branches that are strong, full of lateral buds, and free from diseases and insect pests. Cut the branches with a length of 8 cm and a diameter of 0.5 cm as cuttings. The upper and lower cuts of the cuttings are truncated, and the upper cut is 0.5 cm away from the cut buds. % of wet sand and store them in layers to stimulate roots, and the storage temperature is controlled at 0-5°C; mix the yellow core soil and peat at a volume ratio of 2:1 to make a cutting substrate, and disinfect the cutting substrate with a mass concentration of 70% pentachloronitrobenzene , set aside; mix Shuangjier 6 (GGR6)) 50mg and ammonium molybdate 20g with water to 1kg to make a rooting agent, set aside; at the end of February and early March of the following year, the base of the prepared cuttings was dipped in...

Embodiment 2

[0017] From mid-October to late October, remove the terminal inflorescences of the branches to promote the thick growth of the spikes; in mid-December, select the middle and lower parts of the branches that are strong, full of lateral buds, and free from diseases and insect pests. Cut the branches with a length of 12cm and a diameter of 1.0cm as cuttings. The upper and lower cuts of the cuttings are truncated. The upper cut is 1cm away from the cut buds. The cut is smooth. Place the cut cuttings flat with a moisture content of 60%. The roots are layered and stored in wet sand, and the storage temperature is controlled at 0-5°C; the yellow core soil and peat are mixed at a volume ratio of 2:1 to make a cutting substrate, and the cutting substrate is sterilized with 70% pentachloronitrobenzene. Standby; mix 100mg of Shuangjier 6 (GGR6) and 10g of ammonium molybdate with water to 1kg to make a rooting agent, and set aside; at the end of February and early March of the following ye...

Abstract

The invention discloses a method for raising seedlings by cuttage of hard branches of A. japonica, which comprises the following steps: (1) removing flower buds from a mother tree for picking ears; (2) preparing and storing cuttings; (3) mixing yellow heart soil and peat at a volume ratio of 2:1 Cutting substrates are made, and the cutting substrates are disinfected with a mass concentration of 70% pentachloronitrobenzene; (4) rooting agent Shuangjier 6 and ammonium molybdate are mixed in proportion to make rooting agents; (5) cuttings treatment and cutting; ( 6) Post-planting management and transplanting. The method for growing seedlings by hardwood cuttings of A. japonica described in the present invention has a cutting survival rate of more than 95%. The method is simple and easy to operate, has the advantages of low cost, simple technical requirements, and easy popularization and application. It has important application and promotion value.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for growing seedlings by cutting hardwoods of A. japonicus. Background technique [0002] Fragrance ( EdgeworthiachrysanthaLind1 ) is a perennial shrub belonging to the family Daphneaceae, also known as Sanya, Tanchun, knotted flower, knotted tree, Huang Ruixiang, home incense, hi flower, dream winter flower, lotus bark, and pimple bark tree, because the branches have Three divisions of power, so it is named "Sanya"; Jiexiang is native to China, Japan and other places, and it is distributed in various provinces and regions from Henan and Shaanxi in the north to the south of the Yangtze River Basin in China; the fibers of Jiexiang bark are fine and Glossy, in addition to being used as a raw material for high-grade handmade paper, it can also be used as a raw material for banknote paper.
