A method for introducing and cultivating Hanfu apples in high-altitude mountainous areas

Abstract

The invention discloses a method for introducing and cultivating Hanfu apples into a high-altitude area and belongs to the technical field of fruit tree cultivation. Through steps of orchard establishment, seedling treatment, drought-resistant cultivation of fruit trees, tree form culture, fertilizer and water management and comprehensive control of disease and pest damage, the survival rate of Hanfu apple seedlings in the high-altitude area is increased, the planting range of the Hanfu apples is enlarged, so that young Hanfu apple trees put forth blossoms in three years and take shape and bear fruits in four years, the yield per mu in the fifth year reaches 1208.5 kg, the yield per mu in the sixth year reaches 2513.1 kg, the superior fruit rate reaches 87.5%, and the early fruiting and high yield goals of the Hanfu apples are fully achieved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, in particular to a method for introducing and cultivating Hanfu apples in high-altitude mountainous areas. Background technique [0002] Hanfu Apple is a cold-resistant, high-quality, large-fruit variety selected by Shenyang Agricultural University with Dongguang×Fuji as parents. Hanfu apple has good cold resistance, stress resistance, drought resistance, extensive management resistance, high yield, and obvious economic benefits. Fully colored, the waxy layer of the peel is medium thick, less fruit powder, small fruit spots, short and thick fruit stems; small fruit core, light yellow flesh, crisp flesh, juicy and rich, sweet and sour, with aroma, peeled hardness, The content of soluble solids is 15%, and the total sugar is 12%, which is of high quality and is deeply loved by consumers. [0003] With the increasing export volume of apples, large-scale planting has begun across the...

AI Technical Summary

Problems solved by technology

The northern region is the main production area of ​​apples, and the cultivation altitude is about 1400 meters. Common red Fuji species generally suffer from frost damage at the trunk, rhizome and branches at the base of the main branch, followed by apple tree rot. Rampant damage, and the spread of infection is fast, causing large-scale destruction of the garden in 3-5 years, resulting in less than 65% of the first and second-grade fruit rates in the northern region, less than 30% of the high-quality fruit rate, fewer high-end fruits, and poor overall fruit quality. , the economic benefits of fruit farmers have declined seriously, so in a short period of time, "Hanfu" varieties have been introduced and cultivated in the northern regions

[0004] The vast mountainous area in the northern region has become the main cultivation area for apples. However, the northern mountainous area is high in altitude, with an altitude range of 2500-2857 meters. Due to the limitation of natural conditions such as cold climate, lack of oxygen, and climate, apples are cultivated in high-altitude mountainous areas. Poor quality and low output have seriously restricted the economic development of apples in mountainous areas
