Pear tree cutting seedling-raising method

Abstract

The invention discloses a pear tree cutting seedling-raising method. The method comprises the steps that in the early morning in July, on the condition that the temperature is 20-25 DEG C and the humidity is 70-80%, branches with the length being 8-10 cm of a pear tree are cut down to be used as cutting slips, roots of the cutting slips are soaked and steeped into a potassium permanganate solution for 1-2 min, the roots of the cutting slips are inserted into a rooting agent to be soaked and steeped for 0.5-1 h and then taken out to be inserted into a cutting medium, and then light culture is performed for 45-55 d and then transplanting is performed. By adopting the cutting seedling-raising method, the good characters of pear tree stock plants are kept, and the pear tree cutting seedling-raising method has the advantages that the propagation coefficient is high, plants grow robustly and neatly, and operation is easy and convenient, the reproductive number of seedlings is increased by 60% or above compared with a root embedding seedling-raising method, the fruit yield is stable, and the quality is high.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for raising seedlings by pear tree cuttings. Background technique [0002] Pear trees, belonging to the genus Pyrus in the family Rosaceae, are perennial deciduous fruit trees and are widely distributed around the world. They have the advantages of adaptability, strong disease resistance, and long life. Low yield, unstable yield and other defects, and in the process of cultivation and development of pear trees, it is prone to the problems of variety degeneration, such as the smaller fruit, the shrinkage of the calyx concave, the increase of stone cells, and the weakening of flavor, etc., resulting in the pear fruit market Competitiveness continues to decline, affecting the enthusiasm of fruit farmers. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a pear tree cutt...
