Two-year-old multi-branch dwarf self-rooted rootstock apple seedling culturing method

Abstract

The invention discloses a two-year-old multi-branch dwarf self-rooted rootstock apple seedling culturing method. The method is specifically implemented according to the following steps that a proper culturing nursery construction land is selected, and the land should be the center of an apple industry concentrated development area, convenient in transport, out of the wind, facing the sun and convenient to drain and irrigate; preparation is conducted before seedlings are planted; the land is leveled, the planting density is planned, and a reasonable irrigation system is laid; seedling planting and daily management are conducted. By means of the method, the utilization rate of water and fertilizer can be obviously increased, and the seedling growth requirement can be met without extra manual fertilizing; the purpose of promoting branching can be achieved through only one method, the operation process is greatly simplified, production efficiency is improved, and the method has the obvious advantages of saving water, saving fertilizer, saving manpower and saving land compared with an existing garden building mode in China; furthermore, the apple seedlings cultured through the method have the advantages of being early in fruiting, high in yield and high in quality, and the investment cost can be quickly recovered.

Description

technical field [0001] The invention belongs to the technical field of apple dwarf rootstock breeding, and relates to a breeding method for biennial multi-branched dwarf self-root stock apple seedlings. Background technique [0002] After more than 10 years of production adjustment, my country's apple production has entered a stable development stage, with a cultivation area of ​​about 2 million square meters and an annual output of 30 million tons, ranking first in the world's apple producing countries, and the annual output is still growing at a rate of 7% to 10% per year. speed growth. Statistics show that my country's total apple export from 2009 to 2010 was 1.28 million tons, with an export growth rate of 13.0%, and a contribution rate of 84.08% to the world's apple production increase, which was the highest in the world. It can be said that my country is currently a major producer and consumer of apples. However, in stark contrast to this, my country's apple dwarf sel...

Problems solved by technology

However, the current status quo in my country is that no matter the apple seedlings on the arborization stock or the apple seedlings on the dwarf stock, the quality is not high. After these seedlings are planted, the seedling period is long, the result is late, and the benefit is poor, which cannot bring greater economic benefits to the fruit growers. , which has widened the level of apple planting in my country and the level of advanced countries

At present, there are the following problems in my country's dwarf self-root anvil garden cultivation apple seedlings: the seedlings are cultivated in the garden for a short time, and excellent seedlings cannot be bred; the seedling density per unit area is too high (up to 10,000 plants / 667m 2 ), the quality of inverted seedlings cannot meet the standard
