Fertilizer application combination applicable to planting gala apples in mountainous regions, as well as ground management method

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...

AI Technical Summary

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 acidification of the soil and decline in soil fertility. At the same time, the use of traditional fertilization combinations and management keeps the solid content of the fruit down and the acidity continues. In addition, the fertilization technology is outdated and backward, the amount of chemical fertilizer is large, and the method of digging deep trenches for fertilization requires a lot of labor and high planting costs, which also affects the quality and storability of apples. sex
