Problems solved by technology

The existing fertilization and ground management methods cannot fully meet the needs of the growth and development of this variety, resulting in the inability to fully express the characteristics of the variety, which can easily cause variety degradation, reduced quality, and reduced storability; About 1.5-2 kg of pure nitrogen needs to be applied to one kilogram of apples. The amount of chemical fertilizers is large and the environment is seriously polluted, resulting in acidif

Embodiment 1

[0015] (1) Determine the amount of fertilization: Determine the annual fertilization amount according to the output. For every 100 kg of Gala apples produced, 0.70 kg of pure nitrogen should be applied throughout the year, and pure nitrogen, P 2 o 5 、K 2 The mass ratio of O is 2.5:1:2, that is, for every 100 kg of annual production, it is necessary to apply nitrogen fertilizer containing 0.7 kg of pure nitrogen and 0.28 kg of P 2 o 5 Phosphate fertilizer and containing 0.35 kg K 2 Potassium fertilizer for O;

[0016] (2) Determine the fertilization period and the amount of fertilization in each fertilization period: divide the fertilization amount determined in step (1) into three times for fertilization:

[0017] For the first time, 50% of the annual nitrogen fertilizer amount is applied before spring germination, that is, only nitrogen fertilizer containing 0.35 kg of pure nitrogen is applied;

[0018] For the second time, in the spring shoot stop period, about from May...

Embodiment 2

[0025] (1) Determining the amount of fertilization: Determine the annual fertilization amount according to the output. For every 100 kg of Gala apples produced, 0.73 kg of pure nitrogen should be applied throughout the year, and pure nitrogen and P should be applied throughout the year. 2 o 5 、K 2 The mass ratio of O is 2.5:1:2, that is, for every 100 kg of annual production, it is necessary to apply nitrogen fertilizer containing 0.73 kg of pure nitrogen and 0.29 kg of P 2 o 5 Phosphate fertilizer and containing 0.37 kg K 2 Potassium fertilizer for O;

[0026] (2) Determine the fertilization period and the amount of fertilization in each fertilization period: divide the fertilization amount determined in step (1) into three times for fertilization,

[0027] For the first time, 50% of the annual nitrogen fertilizer amount is applied before spring germination, that is, only nitrogen fertilizer containing 0.36 kg of pure nitrogen is applied;

Embodiment 3

[0035] (1) Determining the amount of fertilization: Determine the annual fertilization amount according to the output. For every 100 kg of Gala apples produced, 0.76 kg of pure nitrogen should be applied throughout the year, and pure nitrogen and P should be applied throughout the year. 2 o 5 、K 2 The mass ratio of O is 2.5:1:2, that is, for every 100 kg of annual production, it is necessary to apply nitrogen fertilizer containing 0.76 kg of pure nitrogen and 0.3 kg of P 2 o 5 Phosphate fertilizer and containing 0.38 kg K 2 Potassium fertilizer for O;

[0036] (2) Determine the fertilization period and the amount of fertilization in each fertilization period: divide the fertilization amount determined in step (1) into three times for fertilization,

[0037]For the first time, 50% of the annual nitrogen fertilizer amount is applied before spring germination, that is, only nitrogen fertilizer containing 0.38 kg of pure nitrogen is applied;

Abstract

The invention discloses a fertilizer application combination applicable to planting gala apples in mountainous regions, as well as a ground management method. The ground management method comprises the following four steps: (1) confirming the fertilizer application quantity; (2) confirming fertilizer application stages and the fertilizer application quantity at each fertilizer application stage; (3) applying a fertilizer by adopting a hole sowing manner; and (4) strictly controlling the irrigation quantity. Through the steps, the solid content of gala apples can achieve 13.8-14.5% (control is at 12.5-13.2%), the content of titratable acid is in general at 0.27-0.33% (control is not less than 0.38%), the acidity is reduced while the solid content is increased, the flavor and storage of fruit can be improved, and the degradation of variety can be effectively prevented; by adopting the hole sowing fertilizer application method instead of deep-groove fertilizer application mode, the fertilizer application quantity can be greatly decreased by more than 50%, the labor for fertilizer application can be reduced, and the planting cost can be effectively lowered; in addition, by adopting farmyard manure combination, fruit trees are facilitated to take in various needed nutrients during growth; the irrigation quantity is strictly controlled, so that not only can the water demand of fruit trees be met, but also water can be saved.

Description

technical field [0001] The invention relates to a fertilization method for apple trees, in particular to a fertilization combination and a fertilization method suitable for planting Gala apples in mountainous areas. Background technique [0002] Gala apple is the main variety of mid-early ripening apples in my country, with a large cultivation area and good economic benefits. Modern agriculture pursues the combination of good varieties and good methods. Different varieties have different growth and development laws and nutrient demand laws. Therefore, each variety must have its unique fertilization technology and management methods. The existing fertilization and ground management methods cannot fully meet the needs of the growth and development of this variety, resulting in the inability to fully express the characteristics of the variety, which can easily cause variety degradation, reduced quality, and reduced storability; About 1.5-2 kg of pure nitrogen needs to be a...
