Method for preventing orange tree weak

Abstract

The invention belongs to the technical field of orange planting, and discloses a method for preventing orange tree weak. The method includes steps of applying barefaced updating trimming and branch retraction updating trimming to a first-grade branch; inwards excavating and fertilizing two soil improvement ditches per tree under water dropping lines at two symmetrical sides of a crown; shearing the exposed roots and flattening the wound; applying commercial organic fertilizer and calcium magnesium phosphate or calcium superphosphate fertilizer yearly; after mixing with excavated soil, backfilling to a fertilizing cave; acidy soil performs inarching and anvil exchanging by red tangerine or fructus aurantii container seedling; alkali soil orangery performs inarching and anvil exchanging by applying an orange anvil container seedling. The main orange stem is injected with carbohydrate to strengthen the tree. According to the tree size, ratio of branch, shoot and leaf, and growth and appearance, flower thinning and fruit thinning are carried out, and fruit carrying is reasonable. Through the demonstration application, the tree vigor of the fruit garden with weak orange trees is recovered to 90% above; the healthy and sustainable development of the mandarin orange industry is promoted.

Description

technical field [0001] The invention belongs to the technical field of citrus planting, and in particular relates to a method for preventing and treating citrus tree weakness. Background technique [0002] Due to the extensive management of Wenzhou citrus orchards in Zhejiang, Hunan and other places, such as long-term application of compound fertilizers and other chemical fertilizers on the soil surface, organic fertilizers are rarely applied, and even organic fertilizers are applied on the soil surface, which causes the root system of the tree to float up, causing the tree to be prone to drought. Or extremely susceptible to adverse environmental stresses such as frost damage, and lack of scientific and reasonable pruning of fruiting trees, large fruit bearing capacity and long fruit bearing period, etc., resulting in tree decline, aging and death in orchards. Investigation and determination of key factors that induce tree weakness, Targeted adoption of tree anti-decay and r...

AI Technical Summary

Problems solved by technology

[0003] In summary, the problems in the prior art are: there is a lack of technical methods for effective prevention and treatment of citrus tree body decline, and more and more plants are declining, aging and dead in the orchard.
