Prevention method for peach tree chlorosis

Abstract

The invention discloses a prevention method for peach tree chlorosis. The prevention method includes the steps of summer pruning, iron fertilizer spraying, supplementary iron fertilizer application to soil and additional organic fertilizer application to improve the soil. The progressive steps of summer pruning, iron fertilizer spraying, supplementary iron fertilizer application to the soil and additional organic fertilizer application to improve the soil are adopted, only when the several measures are used together, can the effect of eradicating chlorosis be achieved, and high quality and the high yield of peach trees are ensured in successive years.

Description

technical field [0001] The invention belongs to the technical field of prevention and treatment of fruit tree yellow leaf disease, in particular to a method for preventing and treating peach tree yellow leaf disease. Background technique [0002] Before and after the peach fruit is harvested, the leaves lose chlorosis in a large area, and the yellowing is serious, which affects the normal photosynthesis of the peach tree, seriously affects the quality of the flower buds, and seriously affects the quality and yield of the fruit. [0003] Analysis of the causes of peach tree yellow leaf disease: [0004] First, there are too many branches and too much pruning in summer. Every summer pruning breaks the balance between the growth of the above-ground part and the growth of the underground part. It inhibits the growth of the root system and the absorption of inorganic salts in the soil by the root system, resulting in a serious lack of iron. [0005] Second: Peach tree, this tre...

[0006] Third, due to the high yield of peach trees, the fruit growers use a large amount of N, P, and K compound fertilizers, which causes the available iron in the soil to be plundered and absorbed, resulting in the lack of iron in the soil, resulting in iron-deficiency yellow leaves in the peach trees.

[0007] Fourth, in some peach orchards, the soil is highly alkaline, most of the available iron in the soil is fixed and transformed into ineffective iron, and the available iron in the soil is greatly reduced, resulting in iron-deficiency yellow leaves in peach orchards.
