Problems solved by technology

However, agricultural control methods are labor-intensive and slow in effect. They are only auxiliary technical means for the control of deciduous disease, and chemical agents are usually used for control. Generally, Bordeaux mixture is sprayed before the onset of disease in June, and in mid-July and mid-August. Combined with the prevention and control of other diseases in the last ten days, spray Bordeaux mixture of the same concentration once each; or spray 50% tuzet 600 times solution every half a month from the first and middle of June, and spray three times in a row; or use 50% wettable Bujin 800-1000 times solution or 50% wettable carbendazim 1000 times solution or 65% wettable zinc zinc 500 times solution
However, excessive application of chemical pesticides will not only increase pesticide residues, but also increase disease resistance and cause pollution to soil, water and ecological environment

Embodiment 1

[0019] A method for preventing and treating early stage defoliation of red Fuji apple trees, comprising the following steps:

[0020] ⑴ preparation stage

[0021] In the first ten days of December, the red Fuji apple trees in the orchard were pruned, and the pruned branches and fallen leaves and weeds in the orchard were collected. The collected materials were crushed into 10-mesh coarse powder in a pulverizer to obtain branch and leaf grass powder. Branch-leaf grass powder is divided into three parts according to the weight ratio of 1:2:3, which are recorded as branch-leaf grass powder A, branch-leaf grass powder B, and branch-leaf grass powder C; put branch-leaf grass powder A in a dryer and dry at 50°C Dry treatment for 30 minutes to obtain branch and leaf grass dry powder A; branch and leaf powder B, dandelion residue, scutellaria baicalensis, decomposed sheep manure, and anaerobic sludge are put into the biogas digester for anaerobic fermentation according to the mass rat...

Embodiment 2

[0031] A method for preventing and treating early stage defoliation of red Fuji apple trees, comprising the following steps:

[0032] ⑴ preparation stage

[0033] In early December, the red Fuji apple trees in the orchard were pruned, and the pruned branches and fallen leaves and weeds in the orchard were collected. The collected materials were crushed into 20-mesh coarse powder in a pulverizer to obtain branch and leaf grass powder. Branch grass powder is divided into three parts according to the weight ratio of 1:2:3, which are respectively recorded as branch grass powder A, branch grass powder B and branch grass powder C; put branch grass powder A in a dryer and dry at 70°C Dry treatment for 50 minutes to obtain dry powder A of branch-leaf grass; put branch-leaf powder B, dandelion residue, scutellaria baicalensis residue, decomposed sheep manure, and anaerobic sludge into a biogas digester in a mass ratio of 22:3:3:6:6 for anaerobic fermentation , separate and collect bio...

Embodiment 3

[0043] A method for preventing and treating early stage defoliation of red Fuji apple trees, comprising the following steps:

[0044] ⑴ preparation stage

[0045] In early December, the red Fuji apple trees in the orchard were pruned, and the pruned branches and fallen leaves and weeds in the orchard were collected. The collected materials were crushed into 20-mesh coarse powder in a pulverizer to obtain branch and leaf grass powder. Branch grass powder is divided into three parts according to the weight ratio of 1:2:3, which are respectively recorded as branch grass powder A, branch grass powder B and branch grass powder C; put branch grass powder A in a dryer and dry at 60°C Dry treatment for 40 minutes to obtain branch and leaf grass dry powder A; branch and leaf powder B, dandelion residue, scutellaria baicalensis, decomposed sheep manure, and anaerobic sludge are put into a biogas digester in a mass ratio of 22:3:3:6:6 for anaerobic fermentation , separate and collect bi...

Abstract

The invention discloses a method for controlling early-falling diseases of Fuji apple trees and belongs to the field of fruit tree disease control. The method comprises the following steps: a preparation stage and three control stages. According to the method disclosed by the invention, biological control serves as a main means, agricultural control serves as an auxiliary means, and the early-falling diseases of Fuji apple trees are reasonably and effectively controlled in stages. Meanwhile, in frequent occurrence months of the early-falling diseases of Fuji apple trees, a small amount of chemical preparations are combined for consolidation and control, possible negative results brought by usage of lots of the chemical preparations can be avoided, and the problem that the existing biological control method is low in control rate and slow in efficacy is solved.

Description

technical field [0001] The invention belongs to the field of disease prevention and treatment of fruit trees, and in particular relates to a method for prevention and treatment of early defoliation disease of red Fuji apple trees. Background technique [0002] Early defoliation diseases of apple mainly include brown spot, gray spot and ring spot, among which brown spot is the most harmful. After the apple tree is damaged, it causes early defoliation, seriously weakens the tree vigor, and even causes overwintering buds to germinate and cause secondary flowering, which has a great impact on the yield of the next year. Seedlings can also be killed, thereby delaying emergence or lowering grades. Early defoliation of apples is one of the most serious diseases in apple production in my country. The control methods for early defoliation include selection of resistant varieties, agricultural control, chemical control and biological control. At present, it mainly focuses on agricul...
