Abstract

The invention belongs to the technical field of tree propagation, and in particular relates to a root cuttage seedling-raising method of tilia miqueliana. The root cuttage seedling-raising method of tilia miqueliana comprises the following steps of: (1), performing stump preparation; (2), performing stump processing; (3), processing before cuttage; (4), performing hormone processing; (5), performing cuttage processing; and (6), managing after cuttage. According to the root cuttage seedling-raising method of tilia miqueliana in the invention, the temperature, the humidity, the illumination andthe ventilation in a culture room are effectively controlled; a good growth environment is provided for stumps; plant hormone solution and auxin are adopted; naphthylacetic acid is a broad-spectrum plant growth regulator; therefore, cell division and expansion can be promoted; tillering can be increased; the percentage of earbearing tiller and the thousand seed weight can be increased; cuttage branches can be promoted to root; the survival rate of seedlings is high; the auxin can promote cell division and differentiation, promote synthesis of RNA and protein, and stimulate growth of leaves andbuds; compound waste liquid is used for promoting rooting of stumps and preventing water deficit or decay of the stumps; and thus, the survival rate of the stumps is increased.

Description

technical field [0001] The invention relates to the technical field of tree propagation, in particular to a method for improving Nanjing linden root cutting seedling cultivation. Background technique [0002] Nanjing linden is a unique tree species of the genus Tilia in my country. It was once widely distributed in East China. It is an excellent native tree species in Jiangsu. It has a long cultural origin, and some places now commonly call it "Bodhi tree". Due to the serious deforestation and ecological environment damage, the number of Nanjing Tilia populations and individuals has dropped sharply, and its wild resources are less, and the roots of wild individuals are sprouting. The value-added coefficient is not high, the fullness of Nanjing Tilia seeds is low and the dormancy period is long, so the reproduction is quite difficult. Contents of the invention [0003] The purpose of the present invention is to provide a method for raising seedlings by root transplanting of ...
