Method for improving cuttage survival rate of rose

Abstract

The invention discloses a method for improving the cuttage survival rate of a rose, which comprises the following steps: in mid June, using furrow hull ash as a matrix to make a cuttage bed and then fully watering and compacting the cuttage bed; using 30 percent carbendazim solution which is diluted by 300 times for sterilizing the matrix before cuttage by using 40g of the carbendazim for per stere of the furrow hull ash; selecting a current growth healthy semi-lignification branch with good sprouts and without diseases; cutting a cuttage branch to have a length of 7-15 centimeters, wherein an upper cut port has a distance of 1 centimeter with a sprout at the upper end and is parallel to a joint, the cut port has smooth and even surface, and a lower cut port is 0.5 centimeter below the joint and cut into an inclined plane of 45 degrees; reserving 2-5 sprouts on each branch and 1-2 pieces of compound leaves on the upper part; dipping the cuttage branch in 30 percent of carbendazim emulsion which is diluted by 500 times for 5-15 minutes; immediately dipping the branch in a heteroauxin solution (500-100mg/L) for 3-5 seconds; keeping a line spacing of 3*10 centimeters of cuttage plants; inserting the branches in the matrix with a depth of 3-5 centimeters; after the branches are inserted, pressing the furrow hull ash on the periphery of the branches solid and fully watering the branches for one time. A full-light intermittent spraying method is adopted to spray and moisturize the branches, and according to different requirements of the branches on water content in different periods, a spraying space and the spraying amount are also reasonably adjusted over time. In every 7-10 days, 50 percent of carbendazim which is diluted by 800-1,000 times are sprayed onto the leaf surfaces to prevent rose diseases. The method improves the survival rate of rose cuttage to 98.1 percent and reduces the seedling culture cost.

Description

technical field [0001] The invention belongs to the field of plant breeding and relates to a method for improving the survival rate of rose cuttings. Background technique [0002] With the improvement of living standards, the people's requirements for the environment are getting higher and higher, and they are no longer limited to the level of greening, but hope that the environment they live in will have flowers in all seasons and fragrance everywhere. Therefore, the flowers are graceful, colorful, fragrant and pleasant, with a long flowering period and wide adaptability, so the Chinese rose is very popular among people. Traditional propagation methods mostly use cuttings, and the cutting substrates generally use perlite, vermiculite, river sand, garden soil, etc. Since vermiculite and perlite are not easy to obtain and costly, the water retention performance of river sand is poor, and the cutting seedlings Later management is more difficult to control and requires more la...
