Embodiment Construction

[0064] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them.

[0065] 1 This application proposes technologies such as improving varieties of old citrus orchards, reducing density of dense orchards, improving crown shape, improving soil, improving drainage and irrigation and road facilities, transforming "small old tree" orchards, and green prevention and control.

[0066] 2 improved varieties

[0067] Variety improvement includes high-grain grafting, grafting rootstocks, etc. High-inoculation replacement is an effective measure to adjust the variety structure, increase the proportion of good varieties, achieve rapid production and realize economic benefits. Butting rootstocks can solve rootstock decay in old citrus orchards, enhance the root absorption capacity of original plants, and improve tree v...

Abstract

The invention belongs to the field of citrus planting, and discloses a method for improving yield and quality of an old citrus orchard, which comprises the steps of variety improvement, thinning of a dense orchard and crown shape improvement. The invention discloses a method for improving the yield and quality of small old citrus trees. The method comprises the steps of soil improvement, irrigation and drainage improvement, balanced fertilization and reasonable pruning. A pest and disease damage prevention and control method for an old citrus orchard comprises agricultural measures and physical measures. The soil quality and tree quality of old orchards and small old tree orchards can be effectively improved, the yield and quality are improved, and pest and disease damage can be efficiently treated in a targeted mode through cooperation of multiple modes.

Description

technical field [0001] The invention relates to the technical field of citrus planting, in particular to a method for improving the yield and quality of citrus old orchards and small old trees and preventing and controlling diseases and insect pests. Background technique [0002] Citrus is a small evergreen tree that usually matures from November to December. In my country, more than 85% of the mid-maturing varieties of citrus mature in November to December. Due to the concentration of citrus on the market, the market competition is fierce and the planting efficiency declines. For this reason, many citrus producing areas have begun to vigorously develop late-maturing citrus in recent years in order to adjust the variety structure, prolong the supply period of fresh fruit, and fill the gap to increase profits. [0003] Most of the old citrus orchards show aging varieties, unsuitable for market demand, low citrus output value, citrus yield and quality decline year by year, orc...
