Chinese rose water planting cutting propagation method

Abstract

A Chinese rose water planting cutting propagation method belongs to the field of research on plant propagation and aims to solve the problems that in Chinese rose cutting, the humidity and temperature are hard to control, a cutting base substrate easily carries diseases and insect pests, the cutting nutrition is quickly consumed and the like. The method can realize the cutting propagation annually, is good in environment controllability and has the survival rate of more than 95%. The method comprises the steps of selection and processing of cutting slips, preparation of a nutrient solution, water planting, daily management and seedling hardening and transplanting. The cutting slips are cut by 10-15cm, and are soaked in a 500-diluted 30% carbendazin emulsion for 5-15 minutes, the lower parts of the cutting slips are soaked in a 30-50mg / Kg ABT NO.2 rooting powder solution for 2-4 hours, are placed into a self-made cutting box, and are cultured by a 1 / 2 Hoagland nutrient solution of which the temperature is 20-25 DEG C, the cutting slips are aerated by 2-3 times every day, the nutrient solution is replaced every 7 days, when cutting seedling roots grow to 1-2cm long, the cutting slips are transplanted into a field, and are watered once every day, the watering frequency is gradually reduced after four days, direct light is avoided, and the cutting slips can survive in 8-10 days.

Description

technical field [0001] The invention belongs to the field of plant propagation research, in particular to the cutting propagation technology of rose. Background technique [0002] Rose (Rosa chinensis) is a deciduous or semi-evergreen shrub in the Rosaceae Rosaceae. It is one of the top ten famous flowers in the world. It has the characteristics of strong adaptability, long flowering period, colorful flowers, and high ornamental value. It is widely used. The vegetative propagation methods of rose include grafting, cutting, branching, layering and tissue culture, among which cutting propagation is the commonly used propagation method in rose production. [0003] The traditional rose cutting method is mainly matrix cutting propagation. There are many studies at present. The research of Luo Jie and others shows that it is better to use vermiculite and perlite as the cutting matrix, while Yan Haixia and others believe that the matrix effect of peat: perlite = 2:1 Better; Guo Pe...

AI Technical Summary

Problems solved by technology

From the above research and invention patents, it can be found that the traditional rose matrix cutting method is greatly affected by internal factors such as the genetic characteristics of rose, branch age, cutting leaf area, as well as environmental factors such as season, temperature, cutting matrix, and growth regulators. Therefore, in production and application, the same cutting method often has problems such as small selectivity range for varieties, cutting time is limited by seasons, cutting temperature and humidity are difficult to control, cutting substrates are easy to carry diseases and insect pests, cuttings nutrient consumption is too fast, etc.
