Cultivation method of high dwarfing stock virus-free apple seedlings

Abstract

The invention discloses a cultivation method of high dwarfing stock virus-free apple seedlings, and belongs to the technical field of apple cultivation. In order to solve the problems that the content of in-vivo viruses of the virus-free apple seedlings is increased constantly with extension of a cultivation process under the influence of external factors, the cultivation method of the high dwarfing stock virus-free apple seedlings is provided. For apple nursery stocks cultivated in the steps of nursery stock treatment, nutrient substrate cultivation, field planting, after-planting management and the like, the survival rate is improved after the apple nursery stocks are transplanted in a large field, and the antiviral ability of the virus-free apple seedlings is fundamentally improved. Compared with virus-free apple seedlings cultivated without using the cultivation method, with the extension of the cultivation process, the content of latent viruses of apples has no obvious rise, the virus-free cultivation of the apple seedlings is fully achieved, and the quality of apple trees is ensured.

Description

technical field

[0001] The invention belongs to the technical field of apple cultivation, in particular to a method for cultivating non-toxic apple seedlings with tall and dwarf stock. Background technique

[0002] Apple (Apple) belongs to Rosaceae (Rosaceae) Malus spp. perennial deciduous trees, trees, native to Europe, Central Asia and western Xinjiang. Apple is the largest fruit industry in China, and the main cultivars are Fuji, Gala, Golden Delicious, Marshal, Guoguang and Jonagold. my country's apple production areas are mainly concentrated in the Bohai Bay, the Northwest Loess Plateau, the old course of the Yellow River and the Southwest cold highlands. Apple is a perennial plant, and with the extension of the cultivation process, most of them are infected and accumulate a variety of viruses. So far, the harm of apple virus disease has spread all over the world, and almost 80% of apple tree seedlings are infected with the virus.
