4. the method for electrolysis water according to claim 3 prevention and treatment semen viciae fabae downy mildew, which is characterized in that it is described spray spray Intensity, which is that blade face is complete, wet drips to limb edge.

Technical field

The present invention relates to a kind of methods for preventing and treating semen viciae fabae downy mildew, prevent and treat semen viciae fabae downy mildew more particularly to a kind of electrolysis water Method.

Background technique

Semen viciae fabae is with a long history in Jiangsu Province's plantation, because its protein content is high, nutritional ingredient is comprehensive, can be used as marketing fresh vegetable Dish, feed, food processing and raw material of industry etc. in recent years, with the adjustment of agricultural planting structure, it is fast to eat semen viciae fabae industry development raw Suddenly, have become a pillar industry of Jiangsu Province's agricultural.In semen viciae fabae growth course, plant disease is to influence its yield and product The main factor of matter.Downy mildew is one of the disease on semen viciae fabae, is mainly caused by vetch downy mildew semen viciae fabae specialized form, it is with ovum Spore in the soil, it is overwintering on invalid body or seed, become the primary source of infection of next year plant morbidity.A large amount of spores are then generated again Capsule and spore are borrowed wind and rain spread in china, then are infected, and have seriously affected the yield and quality of semen viciae fabae in some areas.

Electrolysis water refers to that water carries out electrochemical treatments in special generating device, makes pH value, the oxidation-reduction potential of water Indexs such as (ORP values) change and the general name of the acid electrolyzed functional water and alkali ion water with specific function that generates, can also Referred to as electrolyzed functional water or ion activation water.The functional study early start of electrolysis water in the Japan of phase early 1980s, It is widely studied and applied in fields such as medical treatment, food processing, cultivation and gardening now.In grinding agriculturally Study carefully and using focusing primarily upon sterilizing, disease control and influence etc. to plant breeding growth.

Summary of the invention

In view of the above-mentioned defects in the prior art, the present invention provides a kind of method of electrolysis water prevention and treatment semen viciae fabae downy mildew, solutions The problem of pesticide residue is certainly easily caused using pesticide control semen viciae fabae disease.

Technical solution of the present invention is as follows: a kind of method of electrolysis water prevention and treatment semen viciae fabae downy mildew, is 2.4~2.6 with pH value Electrolysis water is sprayed on the bean plant of downy mildew early stage.

Further, it is that every 3~4d is sprayed once that electrolysis water, which sprays frequency,.

Preferably, spraying time is not high for the morning 8:00~10:00 or 15:00~16:00 in afternoon, temperature of fair weather When 35 DEG C.

Further, to be that blade face is complete wet drip to limb edge the intensity that sprays sprayed.

Compared with prior art, beneficial effect is that semen viciae fabae downy mildew, tool are prevented and treated by acidic electrolytic water to technical solution of the present invention Have efficiently, have no toxic side effect, noresidue, it is low in cost the features such as, strong operability, practicability is prominent, and imitates with pesticide control Fruit difference is not significant, can partially substitute pesticide.

Specific embodiment

Below with reference to embodiment, the invention will be further described, but not as a limitation of the invention.

1) preparation of electrolysis water:

Use the continous way HOH water generator or other electrolysis water apparatus for preparation systems of Wuxi prevailing custom environmental science and technology Co., Ltd Acidic electrolytic water is taken, required pH value (or effective chlorine density) is diluted to tap water, is sealed use.

2) test method:

Field bean plant similar in growing way, incidence is chosen, using 800 dilution of pyrimethanil, difference pH Acidic electrolytic water, tap water are that control sprays processing field semen viciae fabae, specifically prevent and treat once every 3~4d by spraying, spray intensity Entirely wet with blade face, limb edge drips for principle, spraying time be fair weather morning 8:00~10:00 or 15:00 in afternoon~ 16:00 sprays 4 medicines when temperature is not higher than 35 DEG C altogether.3 repetitions of every processing repeat 30 plants of bean plants every time.

3) disease index counts:

Disease index is counted after processing and calculates control efficiency, field semen viciae fabae downy mildew disease index grade scale: 0 grade, Complete stool is disease-free；1 grade, the blade below of complete stool 25% has a small number of scabs；2 grades, the blade below of complete stool 50% have a small amount of scab or 25% blade below has more scab number；3 grades, the morbidity of the blade below of complete stool 75% or the blade below of complete stool 25% are complete Leaf is withered and yellow；4 grades, the blade morbidity or 50% withered and yellow to the whole strain of blade below of complete stool of 75% or more complete stool are withered and yellow.

Disease index=Σ (diseased plant numbers at different levels × typical value at different levels)/(investigation total strain number × highest level typical value) × 100。

The physical and chemical parameter of acidic electrolytic water used by each embodiment and tap water is as follows:

Each embodiment, tap water and 800 dilution of pyrimethanil, which carry out spraying rear effect, to be as follows:
