Method for preventing and controlling chlorosis

Abstract

The invention relates to the field of prevention and control of plant diseases, in particular to a method for preventing and controlling chlorosis. The method for preventing or controlling the chlorosis by regulating the soil structure comprises the following steps of: turning over soil around fruit trees to form ditches; removing the rotted roots of the fruit trees in the ditches, and finding healthy roots; adding soil regulating substances into the soil and mixing uniformly; filling the mixed soil into the ditches around the fruit trees and flattening the soil; and watering the flattened soil so that the soil is soaked with water. The method for preventing or controlling the chlorosis by regulating the soil structure has a good preventing effect and a good control effect. Moreover, the method for preventing and controlling the chlorosis can also be used for regulating the soil beyond the crown edge, so that the development of the roots of the fruit trees can be promoted, and the integral growth of the fruit trees is further promoted; the roots of the fruit trees are damaged slightly; without use of the substances such as pesticide and the like, the method is suitable for green agricultural production; and the disease resistance of the fruit trees is improved, and the quality and the quantity of fruits are also improved.

Description

technical field

[0001] The invention relates to the field of plant disease prevention and control, in particular to a method for prevention and treatment of yellowing disease. Background technique

[0002] Yellowing disease, also known as yellow shoot disease, can be infected by palms, musaceae, Rutaceae and Rosaceae plants. The growth of infected plants gradually weakens, and then the diseased plants gradually die. The fruit of the diseased plant is deformed, the peel becomes soft, and the fruit is small and sour. In addition, yellowing disease can also be transmitted from diseased plants to healthy plants. If it is allowed to spread, it will even cause serious consequences such as tree death and garden destruction, causing huge economic losses to fruit tree growers.

[0003] Existing control methods are ineffective and can only play a limited role, so fruit farmers generally can only dig out the fruit trees that are sick, so as to avoid the expansion of the infected area...

specific Embodiment 1

[0067] A method for preventing and treating the yellowing disease of citrus trees at the age of one year prevents and treats the yellowing disease by regulating the soil structure, and specifically includes the following steps:

[0068] Divide the soil around the citrus trees to form furrows;

[0069] Remove the rotten roots of fruit trees in the ditch and find healthy roots;

[0070] Add the soil conditioning substance to the soil and mix well;

[0071] Fill the mixed soil into the ditch around the fruit tree and level it;

[0072] Water the leveled soil to saturate the soil.

[0073] The soil conditioner is a soil conditioner, and the active ingredient content of the soil conditioner is: 30% of organic matter, 5% of the total amount of nitrogen, phosphorus and potassium; the pH value of the soil conditioner is 5.5.

[0074] Citrus trees suffered from severe yellowing during soil conditioning, and the amount of soil conditioner was 4 kg.

[0079] A 2-year-old method for preventing and treating yellowing disease of apple trees, which prevents yellowing disease by regulating soil structure, specifically comprises the following steps:

[0080] Dig up the soil around the apple tree to form a ditch;

[0081] Remove the rotten roots of fruit trees in the ditch and find healthy roots;

[0082] Add the soil conditioning substance to the soil and mix well;

[0083] Fill the ditch around the apple tree with the mixed soil and level it;

[0084] Water the leveled soil to saturate the soil.

[0085] The soil conditioner is bio-organic fertilizer. The content of effective components in the bio-organic fertilizer is: 45% of organic matter, 15% of the total amount of nitrogen, phosphorus and potassium; the pH value of the bio-organic fertilizer is 7.

[0086] The apple tree did not suffer from yellowing disease during soil conditioning, and the consumption of bio-organic fertilizer was 1kg.

[0093] Remove the rotten roots of fruit trees in the ditch and find healthy roots;

[0094] Add the soil conditioning substance to the soil and mix well;

[0095] Fill the mixed soil into the ditch around the coconut tree and level it;

[0096] Water the leveled soil to saturate the soil.

[0097] The soil conditioner is an organic fertilizer. The active ingredient content in the organic fertilizer is: 30% of organic matter, 15% of the total amount of nitrogen, phosphorus and potassium; the pH value of the soil conditioning substance is 5.5.
