Method for inducing one-year apple sprout resisting anthracnose

Abstract

The invention relates to the fruit tree plantation disease control technology field, and more specifically relates to a method for inducing one-year apple sprout resisting anthracnose, and the method comprises the steps of selecting a one-year apple sprout; removing all leaves on the apple sprout; immersing the sprout in an acidic aqueous solution and then carving a wound on the tree body; then immersing the sprout in an alkaline aqueous solution for nitrogen treatment; then spraying a layer of natto hydrolysate overall on the apple sprout cuticle for wound recovery; and finally transplanting the apple sprout to a revival matrix to cultivate to revival the tree's growth. The one-year apple sprout obtained according to the induction treatment method has a very high anthracnose resisting capability; the induction success rate is more than 98%; the treatment method is simple; the treatment cost is low; and a firm base for planting nuisance-free apple is provided.

Description

technical field

[0001] The invention relates to the technical field of prevention and control of fruit tree planting diseases, in particular to a treatment method for inducing annual apple seedlings to resist anthracnose. Background technique

[0002] Apple anthracnose, also known as bitter rot and late rot, is one of the important fruit diseases of apples. It occurs in most apple producing areas in my country, especially in high temperature, rainy and humid areas in summer. Light brown small round spots first appear on the surface of the fruit, and then expand into dark brown, sunken round spots with clear edges. The flesh of the diseased part is funnel-shaped and rots softly towards the core, brown and has a bitter taste. When the diameter of the lesion is 1 to 2 cm, small black spots arranged in a ring shape grow out of the center, bulge, break through the epidermis, and gushing out red mucus. Several spots merge, and the whole fruit rots. The diseased fruit loses wate...

Embodiment 1

[0019] Embodiment 1, a kind of processing method of inducing annual apple seedling to resist anthracnose, specifically:

[0020] (1) Select 1-year-old apple seedlings, cut off all the leaves on the apple seedlings, add phosphate to the water to adjust the pH to 5.3, completely immerse the apple seedlings in it, and treat them in a water bath at 32°C for 40 minutes;

[0021] (2) Draw wounds on the trunk of the apple tree at intervals of 2 cm, with a depth of 1 mm and a length of 0.5 mm;

[0022] (3) Add sodium bicarbonate to the water to adjust the pH to 6.6, pass nitrogen into the water at a flow rate of 0.3L / min, and continue the treatment for 8 hours;

[0023] (4) Take out the apple seedlings, dry the surface moisture, spray a layer of natto hydrolyzate on the skin of the apple seedlings, and wrap a layer of breathable gauze, and let it stand in an environment with a temperature of 16°C and a humidity of 35%. For 4.5 hours, adjust the temperature to 25°C, and let the humidi...
