Saybrook golden sabina chinensis cuttage propagation method

Abstract

The invention relates to a saybrook golden sabina chinensis cuttage propagation method, which belongs to the technical field of plant propagation and is characterized by comprising the following steps that: 1) proper propagation places are selected for building a saybrook golden sabina chinensis female parent region ear picking nursery garden; 2) 4 to 6 parts of imported peat, 2 to 4 parts of coconut tree branny, 0.5 to 1.5 parts of vermiculite and 0.5 to 1.5 parts of perlite according to the volume ratio are adopted as substrates; 3) the proper cuttage time is early March, and autumn plants in the last year are collected from side branches of female parents of the saybrook golden sabina chinensis for ear shearing; 4) the base parts of ears of cuttage branches are soaked for 2 to 3 seconds by 1400 to 1600 ppm of Sensheng No.5 plant root prompters; 5) 72-hole plug discs are adopted for cuttage, and the process enters a management maintenance stage; and 6) the seedling tempering is carried out when the rooting rate reaches higher than 80 percent. The saybrook golden sabina chinensis cuttage propagation method has the advantages that the plants can adapt to the climate and soil environment in China, the rooting condition is good, the cuttage survival rate is as high as 80 percent, in addition, the operation is simple, and the propagation speed is high.
