Embodiment 1

[0045] (1) Select the desert Caragana shrub that grows robustly, is obviously superior to other plants, and has many sprouts and large growth in the year as the female plant. The main root of the test was cut from the main root of the excavated gene plant on July 10, 2009 and brought back for cutting. On the morning of July 11, cut the young and hard branches of Caragana japonica for cuttings.

[0046] (2) Cut the twigs into 7 cm long cuttings, remove the thorns, and keep 2 rounds of leaves at the upper end. Excessive twigs or tender tips are removed and bundled into bundles of 25 plants. The cuttings were treated with 100ppm ABT1 rooting powder solution, soaked to a depth of 2cm, and soaked for 6.5h. Water immersion for 6.5h was used as the control.

[0047]Cut the harvested hard branches into 12cm long cuttings, remove the thin branches, cut the lower end 0.5cm away from the lower buds into a horseshoe shape, and align the cut cuttings with 25 bases to form a bundle. Put...

Embodiment 2

[0056] (1) Select the desert Caragana shrub that grows robustly, is obviously superior to other plants, and has many sprouts and large growth in the year as the female plant. The main root of the test was cut from the main root of the excavated gene plant on July 13, 2009 and brought back for cutting. On the morning of July 14, cut off the young and hard branches of Caragana japonica for cuttings.

[0057] (2) Cut the twigs into 12 cm long cuttings, remove the thorns, and keep 3 rounds of leaves at the upper end. Excessive twigs or tender tips are removed and bundled into bundles of 25 plants. The cuttings were treated with 100ppm ABT1 rooting powder solution, soaked to a depth of 3cm, and soaked for 6.5h. Water immersion for 6.5h was used as the control.

[0058] Cut the harvested hard branches into 12-15cm long cuttings, remove the thin branches, cut the lower end 0.5-0.8cm away from the lower buds into a horseshoe shape, and align the cut cuttings with 25 bases to form a...

Abstract

The invention relates to a successful cutting propagation method of desert caragana, which comprises the following steps of: selecting a strongly growing bush as a maternal plant, and respectively scissoring a twig, a hard branch and a taproot of the desert caragana for cutting; putting the twig of the desert caragana into 100ppm of growth regulator solution, wherein the soaking depth is 2-3 centimeters, and the soaking time is 6.5-10 hours; putting the hard branch into 500ppm of growth regulator solution, wherein the soaking depth is 2-3 centimeters, and the soaking time is 1-3 hours; soaking the cutting of the taproot in 50ppm of growth regulator solution for 18-20 hours; and selecting a position with flat land and good drainage for arranging a cutting bed, selecting sandy soil as a cutting ground mass, cutting at the depth of 4-5 centimeters, watering after cutting, setting up a shading net in time, watering once every five days, tearing off the shading net after one month, and counting the survival rate after three months. An experiment result indicates that the processing method can ensure the success of the cutting propagation of the desert caragana, and provide abundant germ plasm resources for ecological restoration and stockbreeding production in desert regions.

Description

technical field [0001] The invention relates to the technical field of cutting propagation of plants, in particular to a successful method for cutting propagation of Caragana pheasanta. Background technique [0002] There are more than 100 species of Caragana in the world. They are deciduous shrubs and are famous for their strong drought resistance. Known as a life-saving grass for livestock in pastoral areas. The study on the distribution and floristic composition of Caragana shows that Caragana is mainly distributed in grassland and desert areas. Desert Caragana (C.roborovskyi) belongs to the desert species, distributed in the strong arid desert and the extremely arid desert in Northwest my country. It is an important ecological shrub in the desert area and an important feed species for animal husbandry. Today, when the country attaches great importance to the ecological construction of the western region, research on the rapid reproduction of Caragana species can not on...
