AI Technical Summary

Technical Problem

Existing hydroponic cutting techniques for reeds have problems such as large land area requirements, long seedling time, complex operation, and poor seedling quality.

Method used

Lateral branches of Phragmites australis were used as cuttings. The growth of lateral branches was promoted by removing the tops. Disinfectant, water, rooting agent solution and nutrient solution were sprayed in the seedling pond using an aerosol sprayer. The base of the lateral branches was kept in a high-humidity and light-proof environment to promote rapid rooting. When the roots reached 3-8cm in length, they were directly transplanted to the field.

Benefits of technology

It significantly shortens the seedling cultivation cycle, reduces the land area occupied, improves seedling quality and survival rate, and has a simple and easy process. The cultivated Reed seedlings have good resistance and strong root vitality.

Abstract

The application discloses a method for quickly cultivating strong reed canary grass seedlings based on reed canary grass lateral branches, and belongs to the technical field of reed canary grass propagation, which comprises the following steps: taking a stem with 3-5 qualified lateral branches as a cutting, vertically and closely placing the cutting on a seedling net in a seedling pool, and placing the base of the cutting in a dark environment; during the seedling stage, spraying clean water, a rooting agent solution, clean water and nutrient solution to the seedling pool under the seedling net in sequence through an air sprayer, and keeping the humidity in the seedling pool at 80-90%; and separating the lateral branches from the cutting and transplanting after the seedling stage is completed. According to the method, the reed canary grass is topped to prepare the cutting with qualified lateral branches, and then a high-humidity and light-avoiding environment is utilized to induce the lateral branch base to quickly root, so that the seedling time is significantly shortened, the lateral branch has high hardness and good resistance, the survival rate of the reed canary grass in a field is as high as 98% or more after rooting without domestication, and meanwhile, the space utilization efficiency is high, and the process is simple and easy to implement.
