Seedling raising method suitable for root cutting rapid propagation of pyrus betulaefolia

Abstract

The invention relates to the technical field of seedling cultivation, in particular to a seedling raising method suitable for root cutting rapid propagation of pyrus betulaefolia, which comprises the following steps: (1) nursery selection; (2) nursery land preparation; (3) seminal root selection; (4) cutting preparation; (5) cutting seedling raising; (6) cultivation management; and (7) seedling outplanting. Through effective utilization of the method, the progeny separation phenomenon occurring in the propagation of pyrus betulaefolia seeds is avoided, the excellent characters and inherent characteristics of original parent varieties of pyrus betulaefolia are maintained, the propagation period of the seedlings is shortened, the propagation cost of the seedlings is reduced, the propagation efficiency of the pyrus betulaefolia seedlings is improved, the effect of the good pyrus betulaefolia varieties can be played to the maximum extent, and healthy development of the fruit tree industry is promoted. The method and the thought of the improved pyrus betulaefolia variety propagation are innovated and optimized, a new way for improved pyrus betulaefolia variety propagation is opened up, and the method is an indispensable technical measure in the field of improved pyrus betulaefolia variety propagation.

Description

technical field [0001] The invention belongs to the technical field of nursery stock cultivation, and in particular relates to a seedling cultivation method suitable for root-cutting and rapid propagation of Du pear. Background technique [0002] Du pear (Pyrus betulifolia Bunge), a deciduous tree in the Rosaceae family, often has thorns on its branches. It is light-loving, cold-resistant, drought-resistant, waterlogging-resistant, barren-resistant, and suitable for growth. It can grow normally in neutral soil and saline-alkali soil. It is distributed in plains or hillsides at an altitude of 50-1800m in my country. Duli is not only strong in nature. , the requirements for water and fertilizer are not strict, its tree shape is beautiful, and its color is white, it can be used as a greening tree in streets, courtyards and parks. [0003] Du pears are widely used in saline-alkaline areas in northern China, and can be used as shelter forests and soil and water conservation fores...

Problems solved by technology

[0005] Aiming at the problems of long cycle, low efficiency, high cost and unstable seedling traits of cultivating Du pear seedlings in the prior art, the present invention provides a seedling raising method suitable for root cutting and rapid propagation of Du pear. Propagation of pear seedlings with strong roots not only greatly shortens the cultivation cycle of seedlings, but also avoids the separation of offspring that occurs when propagating with Du pear seeds, and better maintains the excellent characters and inherent characteristics of the original Du pear varieties
