Embodiment 1

[0040] In the Daming Mountain area of ​​Lin’an, Zhejiang, where pecans are widely planted, 12-year-old walnut trees were selected for fertilization and control of pecan dry rot:

[0041] 1) In December, spread decomposed sheep manure along the crown of the tree to 0.5-1m around the hickory trunk, and the dosage is 4.5kg per plant;

[0042] 2) In February of the following year, spread dolomite powder and lime around the hickory tree 0.5-1m in a circular manner, with the dosage of 1.75kg of dolomite powder per plant and 1.0kg of lime per plant.

[0043]3) After the fresh hickory nuts are picked, they are mechanically dehulled to separate the fresh hickory cattail shell waste, control the particle size (5mm) of the fresh hickory cattail shell waste, and adjust its water content to about 60%; then Add 1.5% urea to compost and decompose. After fermenting the fresh hickory cattail shell waste, in March of the next year, sprinkle it on the soil around the hickory tree along the canop...

Embodiment 2

[0046] In the Daming Mountain area of ​​Lin’an, Zhejiang, where pecans are widely planted, 12-year-old walnut trees were selected for fertilization and control of pecan dry rot:

[0047] 1) In December, spread decomposed sheep manure along the crown of the tree to 0.5-1m around the hickory trunk, and the dosage is 3.5kg per plant;

[0048] 2) In February of the next year, apply dolomite powder and lime in a ring-shaped method to 0.5-1m around the hickory tree body. The dosage is 1.5kg of dolomite powder per plant and 0.5kg of lime per plant, and apply it on the decomposed sheep manure. .

[0049] 3) After the fresh hickory nuts are picked, perform mechanical dehulling to separate the fresh hickory cattail shell waste, control the particle size (5mm) of the fresh hickory cattail shell waste, and adjust its water content to about 55%; then Add 1% urea to compost and decompose. After fermenting the fresh hickory cattail shell waste, in March of the next year, sprinkle it on the ...

Embodiment 3

[0052] In the Daming Mountain area of ​​Lin’an, Zhejiang, where pecans are widely planted, 13-year-old walnut trees were selected for fertilization and control of pecan dry rot:

[0053] 1) In December, spread decomposed sheep manure along the crown of the tree to 0.5-1m around the hickory trunk, and the dosage is 5.5kg per plant;

[0054] 2) In February of the following year, spread dolomite powder and lime around the hickory tree 0.5-1m in a ring-shaped method, and the dosage is 2.0kg of dolomite powder per plant and 1.5kg of lime per plant.

[0055] 3) After the fresh hickory nuts are picked, perform mechanical dehulling to separate the fresh hickory cattail shell waste, control the particle size (5mm) of the fresh hickory cattail shell waste, and adjust its water content to about 65%; then Add 2% urea for composting and decomposing. In March of the following year, sprinkle 0.5-1m of soil around the hickory tree body along the canopy, with an amount of 3.0kg per plant, and ...

Abstract

The invention relates to the field of agricultural planting, and discloses a fertilization and prevention method for hickory dry rot, including: 1) spreading decomposed sheep manure around the hickory tree trunk along the canopy from November to March of the next year; 2) ) From November to March of the next year, use dolomite powder and lime in a ring-shaped spread around the hickory tree, and apply it on the decomposed sheep manure; 3) After fermenting the fresh hickory cattail shell waste, the From November to March of the next year, sprinkle the soil around the hickory tree along the crown of the tree, and cover it with sheep manure and dolomite powder or lime; 4) dissolve potassium humate with water, and in May-July of the next year Open a shallow ditch ring just below the periphery of the hickory tree crown and pour it in. After being prevented and controlled by the method of the invention, not only can the disease resistance of hickory trees be improved, dry rot can be effectively prevented and controlled, but also the yield and plumpness of hickory nuts can be greatly improved and the empty seed rate of hickory nuts can be reduced.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a fertilization control method for hickory dry rot. Background technique [0002] Hickory dry rot is the main disease that affects the growth and development of hickory trees and reduces the yield of fruit trees, which seriously threatens the healthy development of hickory industry. [0003] Hickory dry rot mainly harms branches, trunks, trunks and side branches of young trees. The lesion is fusiform in the early stage, dark gray water-soaked swelling, and foamy liquid flows out when pressed by hand. The lesion turns brown and smells like distiller's grains. Afterwards, the sick skin loses water and becomes concave, and many small black spots are scattered on the scabs. When the humidity is high, orange-red colloids emerge from the small black spots. When the hickory dry rot is severe, the lesions expand and cause the cortex to split and black water flows out. In the early...
