Embodiment 1
[0031] The test period is from March 2011 to October 2016. The test site is Yuanchao Village, Feiyun Township, Jingchuan County, Pingliang City, Gansu Province (Jingchuan Test Park, Pingliang Apple Comprehensive Test Station of the National Apple Industry Technology System), the main apple production area in Gansu Province. The area of the test field is The area of the control test field is 1 mu. The test varieties are all Changfu No. 2 apples, and the trees are all 20 years old.
[0032] 1. The experimental field adopts the following technologies:
[0033] (1) fertilization
[0034] In mid-September, the base fertilizer was applied in autumn. On the basis of the original fertilization, 10 kg / plant of bio-organic fertilizer was added. In the bio-organic fertilizer: the number of effective viable bacteria was ≥ 0.2 billion / g, and the organic matter content was ≥ 40%; Potassium humate 0.5 kg / plant.
[0035] (2) Apply tree nutrient solution
[0036] In mid-March, mid-June,...

Abstract
The invention discloses a tree vigor strengthening-based apple rot prevention and treatment method. The method comprises the following steps: carrying out autumn base fertilizer application in the middle of September, and on the basis of original fertilizer application, additionally applying biological organic fertilizer and potassic fertilizer to 10-year-old or older trees; smearing tree trunks and boughs with a tree nutrient solution respectively in the middle of March, in the middle of June and in the middle of August; delaying the pruning date to shorten the wound healing time and decrease the wound infection probability, and protecting pruned edges in time; spraying water to clean the garden respectively in the early March and the late October to decrease the number of bacteria on tree bodies and increase nutrition in the tree bodies; scraping off black scars, and whitewashing the tree trunks to prevent and treat freeze injury and reduce rot. Based on tree vigor strengthening, the resistance of the tree bodies is enhanced; the method is a comprehensive prevention and control method taking prevention as a main measure and black scar scraping as an auxiliary measure; in a prevention and treatment process, by increase of the nutrition in the tree bodies, cleaning of the garden with green pesticide to decrease the number of bacteria on the tree bodies and great reduction of the use amount of chemical pesticide, the aim of green prevention and control is fulfilled, the rot prevention and treatment rate is 95 percent or above, and the effect is obvious.
Description
technical field [0001] The invention belongs to the technical field of prevention and control of fruit tree diseases and insect pests, and in particular relates to a method for preventing and treating apple rot disease based on cultivating tree vigor. Background technique [0002] Apple rot is a common disease in orchard production management, and it is one of the most important causes of orchard destruction. Apple rot is a weakly parasitic fungus. The fungus overwinters in the woody interior of disease spots or scars of fruit trees with mycelium, conidia and ascus. The disease spots produce conidia in early spring, and the spores spread with wind and rain. It invades the tree body from sawing cuts, frost wounds, pest injuries, etc., or leaf scars with dead tissues, fruit stands, fruit stalk scars, and bark layers. [0003] The main causes of apple rot disease are the following four: one is that the load on the tree is too large, and the "big and small years phenomenon" is ...
