Problems solved by technology

[0004] Some local experts believe that this is caused by soil acidification. In recent years, large-scale soil acidification treatment has been carried out, but the results are not satisfactory.
Pathologists believe that diseases caused by germs should be treated with medicaments. The treatment method is to spray the soil surface with an aqueous solution of fungicides, and the effect is not good.

Embodiment 1

[0078] The test was carried out in the 1-year-old hickory seedling seedling raising field, and the time was from April to June. 50 hickory seedling seedlings with root rot were selected. Severe rot requires aggravated chemical treatment, which is handled according to the following steps:

[0079] Step 1, loosen the soil. Loosen the topsoil at a depth of about 20 centimeters and 1.5 to 2 meters outward from the trunk.

[0080] Step 2, pouring or pouring the hole fertilizer mixture; the fertilizer mixture includes Fusaide, Wojiafu and phosphorous acid.

[0081] After mixing 90-100 ml of Fosaide and 30-50 ml of Jiafu Jiafu, add 5-8 grams of phosphorous acid, add 35-50 liters of water, and mix well to obtain a fertilizer mixture.

[0082] Pour the mixture over the roots of the tree;

[0083] Or punch 10-30 holes in the soil layer around the roots of the tree, each hole is 20-30 cm deep, and pour the fertilizer mixture into the holes.

[0084] Step 3, the soil is exposed to the...

Abstract

The invention discloses a hickory nut root disease control method, and belongs to the technical field of seedling disease and pest control. The method comprises the following steps: dividing root diseases of hickory nut trees into three levels according to the degrees of disease severity; carrying out soil loosening; carrying out pouring or filling holes with a fertilizer-pesticide mixed solution; and solarizing the soil. The method has the advantages of practicability and wide active range, and often shows consistent performance in agriculture compared with a biological treatment method.

Description

technical field [0001] The invention belongs to the technical field of nursery stock disease and insect pest control, in particular to a method for preventing and controlling pecan root diseases. Background technique [0002] Hickory (scientific name: Carya cathayensis Sarg.) is a plant of the family Juglandaceae and the genus Hickory. Root rot on hickory trees is a common disease of hickory nuts. Root rot of hickory trees can lead to dead trees in severe cases. Therefore, it is necessary to diagnose and treat trees with symptoms, and at the same time, prevent trees without symptoms. [0003] To solve the technical problem of hickory tree root rot, it is necessary to find a suitable agent and study how the agent reaches the lesion, maintain a long-term bactericidal effect, and at the same time promote the growth of the hickory root system. The principle of disease prevention and control is: Do not use highly toxic and high-residue pesticides to prevent the pesticide residu...
