The method is reasonable, convenient to implement and good in effect.

Description

A kind of method of preventing and treating of apple valsa canker

Technical field:

The present invention relates to pest and disease control of fruit trees technical field, be specifically related to a kind of method of preventing and treating of apple valsa canker.

Background technology:

Apple valsa canker is commonly called as smelly skin disease, skin rot, string skin disease, is one of more serious disease of China's apple producing region harm.Limb is injured, and scab has ulcer and withered two types of branch.Ulcer type: sick portion is bronzing, water stain shape, slightly protuberance, diseased tissues is soft rots, and permanent current goes out yellowish-brown juice, has vinasse taste.Later stage drying shrinkage, sink, and there is obvious pore (being pycnidium) in sick portion, when moist. the crocus tendril thing of gushing out from pore.The withered type of branch: mostly occur at positions such as sprig, Guo Tai, dry stakes, sick portion is not water stain shape, and dehydration is withered rapidly causes full branch withered, upper raw black small grain point.Fruit is injured, scab chocolate, and circular or irregular shape, has wheel line, is soft rotten shape, slightly vinasse taste, often there is obvious pore at scab middle part.

This disease is mainly survived the winter in disease tree tissue and residual body with mycelium, pycnidium and perithecium, and germ can be sick portion survival about 4 years.In next year pycnidium, discharge conidium, by the rainwater propagation of splashing, invade from wound.Germ has the dip-dye of hiding characteristic, when tree body or its local organization are when weak, just can expand and spread.Contaminate general 3～May, starts morbidity 7～August, and be onset peak period early spring, and after late spring, premunition strengthens, and morbidity falls sharply.The generation of this disease and tree vigo(u)r, wound number, callus ability etc. are closely related.Extensive management and periodically freeze injury are Major Epidemic factors.

Once the morbidity of this disease, suffers heavy losses, can make apple tree withered gradually, cause death, will make like this fruit tree cannot normal growth, result, can cause huge economic loss.

Summary of the invention:

Technical problem to be solved by this invention is to overcome existing technological deficiency a kind of method of preventing and treating that method is reasonable, implement convenient, respond well a kind of apple valsa canker is provided.

Technical problem to be solved by this invention adopts following technical scheme to realize:

The method of preventing and treating of apple valsa canker, is characterized in that: comprises the following steps,

Step 1, reinforcement fruit tree management: the rational application of fertilizer, every production 1kg fruit, need to apply fertilizer 2kg, phosphate fertilizer 0.7kg.Will control in addition output, flower thinning, maintains the average annual output in orchard in 3000kg in good time.After fallen leaves, should whitewash in time, have the fruit tree protectant of wound to smear;

Step 2, in time remove band hyphostroma: wipe out in time the branch that carries disease germs, remove scab, strike off and always stick up skin, and band hyphostroma is ruined with baked wheaten cake or take field out of;

Step 3, the rational use of medicines: set body early spring and just started recovery, spray in time medicine control, spray the lime sulfur of 3-5 ° of Be;

Step 4, treat scab in time: can be by cutting off the method for scab, 3cm place around scab, deeply cuts and reaches xylem, removes the scab cutting off, and smears bacteria remover protection.

Beneficial effect of the present invention is: very simple, easy-to-understand of above-mentioned step, and very clear, be applicable to specialty or common staff's reference and use, and the plantation output of pesticide dosage and regulation is also very clear, like this with regard to handled easily.The inventive method is reasonable, enforcement is convenient, respond well.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.

The method of preventing and treating of apple valsa canker, is characterized in that: comprises the following steps,

Step 1, reinforcement fruit tree management: the rational application of fertilizer, every production 1kg fruit, need to apply fertilizer 2kg, phosphate fertilizer 0.7kg.Will control in addition output, flower thinning, maintains the average annual output in orchard in 3000kg in good time.After fallen leaves, should whitewash in time, have the fruit tree protectant of wound to smear;

Step 2, in time remove band hyphostroma: wipe out in time the branch that carries disease germs, remove scab, strike off and always stick up skin, and band hyphostroma is ruined with baked wheaten cake or take field out of;

Step 3, the rational use of medicines: set body early spring and just started recovery, spray in time medicine control, spray the lime sulfur of 3-5 ° of Be;

Step 4, treat scab in time: can be by cutting off the method for scab, 3cm place around scab, deeply cuts and reaches xylem, removes the scab cutting off, and smears bacteria remover protection.

More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
