The prevention method of shallot pest and disease damage
Technical field
The present invention relates to agriculture seedling-raising technique field, more particularly to a kind of prevention method of shallot pest and disease damage.
Background technology
Shallot is Liliaceae allium, and herbaceos perennial is originating in China, is distributed all over the world now.Currently, I
The nursery of state shallot remains unchanged using the backward outdoor seedling raising manners in crop field, mainly Furadan, chlopyrifos etc. is used to have high poison, height
Remaining insecticide and each series bactericidal agent, do not have the effect of growth promotion, promoting root growth strong sprout, and not only young plant quality is very different, and
And seedling stage diseases and pests also occur often.In the prior art, all it is to take measures to carry out again after being found that disease hair when actually planting
Treatment, and some diseases cause prodigious influence once in discovery later on the growth of green onion seedling, it is not only difficult to treat, but also lose
Seriously.
Invention content
The purpose of the present invention is overcome the deficiencies of the prior art and provide during one kind can prevent shallot industrial seedling rearing
Incidental major part pest and disease damage, can be substantially reduced shallot seedling stage incidence, improve green onion seedling survival rate, reduce because of pest and disease damage
Bring the prevention method of the shallot pest and disease damage of loss.
In order to achieve the above objectives, the technical solution adopted by the present invention is:The prevention method of shallot pest and disease damage, specific steps are such as
Under:
1)Fine site preparation removes preceding crop residuum, applies 4 ~ 6kg/ mus of " pipe is on earth " later, does behind ridge with liquid manure
Spray 20 ~ 30kg/ mus of seaweed microbial bacterial agent;
2)It weeds out the rank grass in time, and sprays 20 ~ 30kg/ mus of the seaweed microbial bacterial agent;
3)Band invalid body is eliminated, removes Folium Allii fistulosi of being scattered in time after artificial neat seedling every time, and then spray a bactericide
Agent;The bactericidal agent is by 750 times of liquid of beneficial bacteria prestige wettable powder, 80% 3000 times of dimethomorph water dispersion granula liquid, and 80%
1100 times of liquid of S-Ethyl ethylthio sulfonate aqua, general 750 times of liquid of missible oil of making every effort to overcome mix;
4)Medicament is periodically carried out to spray, it is specific as follows:
41)Rigid seedling of appearing:With medicament beneficial bacteria prestige 750 times of liquid of wettable powder, 80% dimethomorph water dispersion granula 3000
Times liquid, 80% 1100 times of S-Ethyl ethylthio sulfonate aqua liquid are general to make every effort to overcome 750 times of liquid of missible oil, 500 times of liquid of standing grain power aqua, pure of glucose analysis
1500 times of liquid of grain, photosynthetic element 15000 times of liquid of wettable powder, 750 times of liquid of Fish protein aqua sprayed primary every 3 days;
When insect pest occurs for this phase, add emamectin-benzoate aqua with 1500 times of liquid of effective cypermethrin aqua
2500 times of liquid sprayed once every 3 days, or were sprayed within every 9 days once using 1500 times of liquid of Rynaxypyr missible oil;
42)Just go out the 2nd leaf seedling:With 750 times of liquid of medicament beneficial bacteria prestige wettable powder, 80% dimethomorph water-dispersible grain
3000 times of liquid of agent, 80% S-Ethyl ethylthio sulfonate aqua, 1100 times of liquid, first frost hymexazol aqua general make every effort to overcome 750 times of liquid of missible oil, standing grain power aqua
500 times of 1500 times of liquid of the pure particle of 500 times of liquid, glucose analysis, 15000 times of liquid of photosynthetic plain wettable powder, Fish protein aqua liquid,
It was sprayed every 3 days primary;
When insect pest occurs for this phase, add emamectin-benzoate aqua with 1000 times of liquid of effective cypermethrin aqua
1800 times of liquid sprayed once every 3 days, or were sprayed within every 9 days once using 1000 times of liquid of Rynaxypyr missible oil;
43)Later stage medium seedling:When green onion seedling 15 ± 2cm of plant height, with 750 times of liquid of medicament beneficial bacteria prestige wettable powder, 80% alkene acyl
1500 times of liquid of morpholine water dispersible granules, 80% S-Ethyl ethylthio sulfonate aqua, 1100 times of liquid, first frost hymexazol aqua general make every effort to overcome 750 times of missible oil
Liquid, 300 times of liquid of standing grain power aqua, 1500 times of liquid of the pure particle of glucose analysis, 15000 times of liquid of photosynthetic plain wettable powder, fish egg
300 times of liquid of plain boiled water agent sprayed primary, another addition thiophanate methyl 600 times of liquid of wettable powder every 9 days every 3 days;
When insect pest occurs for this phase, with 750 times of liquid of effective cypermethrin aqua, emamectin-benzoate aqua
500 times of 1500 times of liquid, organosilicon aqua liquid sprayed primary every 3 days;Or Rynaxypyr 1500 times of liquid of missible oil are used, every 9 days
It sprays primary;
44)Fast transplanting seedlings:Folium Allii fistulosi is cut when 2-3 days before transplanting, is sprayed after having cut Folium Allii fistulosi, with medicament beneficial bacteria
750 times of liquid of prestige wettable powder, 80% dimethomorph water dispersion granula, 1500 times of liquid, 80% S-Ethyl ethylthio sulfonate aqua, 1100 times of liquid, first frost
Hymexazol aqua general makes every effort to overcome 750 times of liquid of missible oil, 250 times of liquid of standing grain power aqua, 1500 times of liquid of the pure particle of glucose analysis, fish egg
600 times of 300 times of liquid of plain boiled water agent, thiophanate methyl wettable powder liquid;
When insect pest occurs for this phase, 600 times of liquid of effective cypermethrin aqua, emamectin-benzoate aqua are sprayed
500 times of 1000 times of liquid, organosilicon aqua liquid;Or 500 times of 750 times of liquid of Rynaxypyr, organosilicon aqua liquid are sprayed, every 9 days
It sprays primary.
Preferably, the prevention method further includes being coated processing to naked seed before seed sowing:By fungicide and kill
Worm agent is wrapped in naked seed surface, wherein the fungicide is one or more in metalaxyl-mn-zn, carbendazim, thiram
Combination, insecticide is imidacloprid.
Preferably, step 4)Employed in photosynthetic plain wettable powder purchased from fertile magnificent agricultural science and technology(Jiangsu)Share is limited
The photosynthetic element of company's production.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art:
1)The conservative idea for changing traditional " sick ability laxative " effectively reduces disease pest with " putting prevention first, anti-rush combines "
Harmful generation;
2)It, can not only by addition using microbial-bacterial fertilizer, standing grain power, S-Ethyl ethylthio sulfonate, glucose, beneficial bacteria prestige, photosynthetic element
Realize the effect for killing pathogen, moreover it is possible to the robust growth for effectively facilitating green onion seedling significantly improves itself premunition of green onion seedling, and
Medicament is mostly green, biological agent, high-efficiency environment friendly;
3)By artificial neat seedling technical measures, while breaking green onion seedling apical dominance, nutrition is fully applied to green onion seedling root
In system and cross growth, it can significantly make green onion seedling thickening, promote root growth, improve green onion seedling itself drag.
Specific implementation mode
