Problems solved by technology

[0004] At present, measures such as strengthening orchard management, isolation and soil disinfection, and chemical root irrigation are used to prevent and control root rot. Orchards with heavy soil and high groundwater level should pay attention to drainage; (3) Scientific pruning, reasonable load, make the canopy ventilated and light-transmitting, prevent the phenomenon of large and small years, and keep the tree vigorous; (4) Prevent other diseases and insect pests, prevent sunburn and frost damage ; but this measure can only prevent or reduce the occurrence of root rot, and cannot treat the diseased plants
The methods of isolation and soil disinfection are used to prevent and control the diseased fruit trees, including: (1) isolation: dig a deep trench of more than 1m around the diseased area to prevent the spread of bacteria; (2) soil disinfection: soil disinfection

Example Embodiment

[0026] Example 1

[0027] A method for preventing and curing fruit tree root rot includes the following steps during the growth period of the fruit tree:

[0028] (1) Apply bio-organic fertilizer to fruit trees in autumn. The bio-organic fertilizer is microbial fertilizer (2014) Zhunzi (1389) No. 1389 produced by Henan Bazhong Modern Agriculture Co., Ltd.;

[0029] (2) Before the fruit trees sprout in the second spring, at a distance of 20cm from the projection line corresponding to the crown of the fruit tree (the projection line of the crown perpendicular to the ground), dilute the root rot control agent of the fruit tree by 1000 times to irrigate the root with the irrigated root depth 20~ 30cm, 1~1.5cm in diameter, 8 evenly distributed root irrigation points. The dosage of root irrigation is based on the leaching liquid on the surface of the soil. Two adjacent root irrigation points are staggered inside and outside the projection line of the canopy, see figure 1 ;

Abstract

The invention relates to a root rot disease prevention and treatment pesticide of fruit trees, aiming at solving the technical difficulty that root rot diseases are difficult to prevent and control. The root rot disease prevention and treatment pesticide is prepared from the following raw materials in percentage by weight: 3%-10% of humic acid, 10%-50% of macroelements, 0.3%-1.5% of a plant growth regulator, 0.5%-1% of a sterilizer and the balance of water. The invention further discloses a root rot disease prevention and treatment method which mainly comprises the following steps: (1) annularly applying a biological organic fertilizer in autumn; (2) before germinating in spring of the next year, carrying out pesticide root irrigation by utilizing the root rot disease prevention and treatment pesticide in a range of being 20cm-30cm away from projection lines of tree crowns; and (3) if finding the fruit trees have a root rot disease, carrying out the pesticide root irrigation by utilizing the root rot disease prevention and treatment pesticide in a range of being 30cm-40cm away from the projection lines of the tree crowns. According to the root rot disease prevention and treatment pesticide and method of the fruit trees, prevention and treatment can be combined, and dual management is carried out on the fruit trees and soil; and sterilization and nutrients are combined in the pesticide, the effects are mutually promoted, and the prevention and treatment effects are remarkable.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to an agent and a method for preventing and treating fruit tree root rot. Background technique [0002] Root rot is a devastating disease that harms fruit trees such as apples, pears, peaches, and grapes. In recent years, due to the insufficient scientific and reasonable fertilization of some fruit farmers, the excessive phosphorus in the soil cannot be absorbed and utilized by fruit trees, and it also has a certain antagonistic effect on nitrogen, which aggravates soil compaction and damages permeability, resulting in fruit tree resistance. Sickness is greatly reduced. In addition, some fruit farmers overuse ammonium bicarbonate, which can easily cause root burn, and unfermented and decomposed human and animal manure, straw, etc., which also aggravate the occurrence of root rot. [0003] Fruit tree root rot mainly includes five kinds of purple-patterned feath...
