Problems solved by technology

However, there are many deficiencies in collecting seeds for reproduction and breeding: on the one hand, the time for field resource investigation is not necessarily the seed maturity period; on the other hand, it is difficult for the collected seeds to maintain the excellent characteristics of the female parent
However, fresh horsethorn branches are directly cut, and the rooting ability of the branches is weak, the rooting rate is low, and the survival rate is not high.

Embodiment

[0034] The method for the asexual reproduction of horse thorn adopts the following steps:

[0035] (1) Cutting bed preparation

[0036] According to the needs of the test, potted cuttings were used, and the plastic seedling box was 40 cm wide, 80 cm long, and 22 cm high. A 15cm high perlite matrix is ​​packed into the nursery box.

[0037] (2) Strip picking and fringe making

[0038] In mid-April, select the current year or annual branches of the plant, collect them with scissors on cloudy days or when the dew is not dry in the morning, put the cut branches in a bucket or wrap them with wet cloth or plastic film, and transport them to the branch processing place as soon as possible Processing: Rinse the cuttings with clean water before processing, remove the top buds from the branches in a cool place indoors or outdoors, and then cut them into cuttings with 4-5 lateral buds, the length is 10-15 cm, and the upper incision is 0.5 above the node. -1 cm, the lower incision is b...

Abstract

The invention provides a vegetative propagation method for Wushan indigofera pseudotinctoria. The method comprises the following steps that steeping is conducted for 1-24 h through growth hormones (naphthylacetic acid (NAA), indoleacetic acid (IBA), zeatin (Z) and rooting powder) with special concentrations, and then cuttage propagation is conducted, so that the survival rate and the rooting capacity of the indigofera pseudotinctoria are improved. A large number of experiments prove that NAA-100-6 treatment is the ideal vegetative propagation method for the Wushan indigofera pseudotinctoria, and the survival rate of braches of the Wushan indigofera pseudotinctoria can be effectively improved by adopting the cuttage method.

Description

technical field [0001] The invention relates to a method for asexual propagation of horse thorns and belongs to the field of breeding of wild leguminous shrubs. Background technique [0002] Horse thorn, also known as Spikegrass, also known as Long Spike Magnolia, is a small perennial shrub of the legume family Magnolia. Features, widely used in green belts, wetlands and parks on both sides of the expressway. In addition to being used for ecological slope protection and soil and water conservation on highway slopes, horse thorn is also a forage grass, which has multiple uses such as medicine, ornamental, food, energy, and health care. Although horse thorn is widely used, germplasm resources are very scarce. At present, domestic and foreign studies on Hippophae thorn mainly focus on the biological characteristics, cultivation and compound Chinese patent medicine of Hippophae thorn, and less involve the innovation and development of Hippophae thorn germplasm. The collection...
