Abstract
The invention relates to a clonal propagation method of Chinese walnuts. Annual half-lignification robust branches are selected and shorn into cuttage branches which are 10-15 cm long, the cuttage branches are placed in a rooting powder solution of an ABT1 number to be soaked for 4-6 h after being pre-processed in a vitamin C and potassium permanganate solution, and then the form lower ends of the cuttage branches are inserted into a matrix. Through the methods of intermittent automatic spraying, sunshade and the like, the temperature, the humidity and the illuminance in a seedling growing greenhouse are adjusted. Statistics is performed on the rooting rate after 60 days, the rooting rate is as high as 85% or above, and the percentage of seedling emergency reaches 80% or above. The rooting rate is 0% if no pre-processing is performed and only processing of plant hormone is performed. The method is high in operability, low in cost and easy to popularize, and meanwhile, and the advantages that high quality of female parents is kept for seedlings and flowering and fruiting are in advance because of cuttage propagation are reflected in clonal propagation of Chinese walnuts.
