Method for preventing and treating root rot of kiwi fruits

Abstract

The invention provides a method for preventing and treating root rot of kiwi fruits. The method comprises the following steps of removing flowers and fruits of diseased or infected plants when the diseased or infected plants with the root rot of the kiwi fruits are found; spraying a nitrogen-phosphorus-potassium water-soluble fertilizer to the leaf surfaces of the kiwi fruits, cleaning ditches anddraining water; digging soil around the kiwi fruit plants to form annular pits, scraping off lesions, smearing scars with smearing liquid, applying root watering liquid into the soil within the 1 m radius range of the kiwi fruit plants, wetting pine barks with stirring liquid, filling the annular pits with the pine barks, punching holes twice within 50 cm of the peripheries of pine bark rings, injecting ozone functional water, and injecting the ozone functional water into all the holes once every month until November; digging annular ditches, fertilizing and earthing 1 m away from the kiwi fruit plants in the first ten-day period of November; and punching holes for the third time and fourth time within the range of 50 cm of the peripheries of the pine bark rings on March to April and Juneto July at the next year, and injecting the ozone functional water. The method is simple, convenient, quick in effect, obvious in effect and low in recurrence rate, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of prevention and treatment of kiwifruit root rot, and in particular relates to a method for preventing and treating kiwifruit root rot. Background technique [0002] Kiwifruit root rot is one of the main diseases that harm kiwifruit. Due to root rot, a large amount of nutrients cannot be obtained from the soil, and the root system itself lacks nutrients and cannot grow normally. The absorption of nutrients from the soil is blocked, affecting the growth and metabolism of the plant. Eventually the tree dies. The incidence of kiwifruit root rot is high in gardens with heavy soil and poor air permeability, and the impact of kiwifruit root rot on yield is increasing year by year. At present, the main methods to prevent and control kiwifruit root rot are to increase the air permeability of the soil by adding organic fertilizers and to dry roots and irrigate pesticides. For a long time, root irrigation in the ai...

Problems solved by technology

At present, the main methods to prevent and control kiwifruit root rot are to increase the air permeability of the soil by adding organic fertilizers and to dry roots and irrigate pesticides. If the time is long, the root rot cannot be fundamentally inhibited by root irrigation, and the recurrence rate is high.
