Problems solved by technology

Therefore, the traditional method of promoting rooting of cuttings is generally to improve the rooting rate and root development of cuttings by using exogenous growth hormones to treat cuttings. The exogenous hormones used in production generally include NAA, IAA, IBA and ABT (rooting hormones). Powder), etc.

Embodiment Construction

[0012] The material used in the present invention is Populus tomentosa Carr, provided by the Biotechnology Research Center of Shanxi Academy of Agricultural Sciences. In the first and middle ten days of March (climate conditions are different in different places), strong lignified branches of 1 to 2 years without pests and diseases are selected for cutting. The cuttings are about 10 to 15 cm long, preferably with 2 to 3 buds. The cut cuttings are bundled into small bundles. Mix substrate and garden soil on the bottom of the seedbed, the substrate accounts for 50%, the substrate has good heat preservation, heat insulation, ventilation, water retention, and fertilizer retention, and is an excellent cutting substrate, then use 30% carbendazim 500 times solution to sterilize the matrix. Irrigate the seedbed thoroughly with water before cutting, and carry out cutting 2 to 3 hours after substrate treatment. The experimental site is located in the greenhouse of the Biotechnology Re...

Abstract

A method for improving cuttage rooting and survival rate of shrub woody plant with ultrasonic treatment aims at realizing simple operation and capability of treating large quantity of cuttage. The method of the invention comprises: clipping strong 1 to 2-year-old branches of woody plant without disease and insect pest, and bundling up the clipped branches; placing the clipped branch bundle into ABT solution, and dipping with a treatment method of dipping root; treating the clipped branches with a ultrasonic wave generating unit, wherein the ultrasonic intensity is 200W to 400W, and the treating time is 30s to 60s; timely watering and weeding after cutting; preparing a seedbed, and laying base material and garden soil which are mixed on the bottom of the seedbed, wherein the weight percent of the base material and the garden soil is 50 percent; sterilizing the base material with 500 times solution diluted by 30 percent of carbendazim; watering the seedbed thoroughly; cutting after 2 to 3h when the treatment of the base material is completed; and sticking the treated branches in the prepared seedbed.

Description

technical field [0001] The present invention relates to a new method for treating the cuttings of arbor woody plants with ultrasonic waves and hormones to improve their survival rate and promote root system development technical background [0002] In the vegetative propagation of trees, there are currently several vegetative propagation methods such as cuttings, grafting and tissue culture. From the perspective of technology economy and simplicity, cutting propagation is an ideal technology. During the cutting process, the rooting of cuttings is not only affected by endogenous hormones, but also regulated by exogenous hormones. This is because exogenous growth hormones can provide cuttings with growth-promoting substances required for rooting and promote the synthesis of endogenous hormones in cuttings. , and can promote the differentiation of a root primordium to form multiple root tips to induce the morphogenesis of adventitious roots in cuttings. Therefore, the traditio...
