The prevention method of shallot damage by disease and insect
Technical field
the present invention relates to agriculture seedling growing process field, particularly a kind of prevention method of shallot damage by disease and insect.
Background technology
shallot is Liliaceae allium, herbaceos perennial, originates in China, all has distribution all over the world now.Current, the nursery of China shallot still adopts the outdoor seedling raising manners in land for growing field crops fallen behind, main employing Furadan, chlopyrifos etc. have high poison, the insecticide of high residue and each series bactericidal agent, do not possess growth promotion, urge the effect in root strong sprout, not only young plant quality is very different, and seedling stage diseases and pests also occurs often.In prior art, be all taken measures again to treat after having found sick sending out when reality is planted, and some disease once just cause very large impact to the growth of green onion seedling after discovery, is not only difficult to treatment, and loss is serious.
Summary of the invention
the object of the invention is to overcome the deficiencies in the prior art, there is provided one can prevent incidental most of damage by disease and insect in shallot factorial seedling growth process, obviously can reduce the shallot incidence of disease in seedling stage, improve green onion seedling survival rate, reduce the prevention method of the shallot damage by disease and insect bringing loss because of damage by disease and insect.
for achieving the above object, the technical solution used in the present invention is: the prevention method of shallot damage by disease and insect, and concrete steps are as follows:
1) meticulous wholely, remove preceding crop residual body, use " pipe is on earth " 4 ~ 6kg/ mu afterwards, after doing ridge, spray marine alga microbial bacterial agent 20 ~ 30kg/ mu with liquid manure;
2) weed out the rank grass in time, and spray described marine alga microbial bacterial agent 20 ~ 30kg/ mu;
3) eliminate band invalid body, after each artificial neat seedling, remove the green onion leaf that is scattered in time, and spray a bactericidal agent subsequently; Described bactericidal agent by beneficial bacterium prestige wetting powder 750 times of liquid, 80% dimethomorph water dispersion granula 3000 times liquid, 80% 1100 times, S-Ethyl ethylthio sulfonate aqua liquid, Pu Like missible oil 750 times of liquid mix;
4) regularly carry out medicament to spray, specific as follows:
41) just to have appeared seedling: with medicament benefit bacterium prestige wetting powder 750 times of liquid, 80% dimethomorph water dispersion granula 3000 times liquid, 80% 1100 times, S-Ethyl ethylthio sulfonate aqua liquid, generally make every effort to overcome missible oil 750 times of liquid, standing grain power aqua 500 times of liquid, the pure particle of glucose analysis 1500 times of liquid, photosynthetic plain wetting powder 15000 times of liquid, Fish protein aqua 750 times of liquid, sprayed once every 3 days;
this phase, when there is insect pest, adds emamectin-benzoate aqua 2500 times of liquid with beta-cypermethrin aqua 1500 times of liquid and sprayed once every 3 days, or adopts Rynaxypyr missible oil 1500 times of liquid to spray once in every 9 days;
42) the 2nd leaf seedling has just been gone out: with medicament benefit bacterium prestige wetting powder 750 times of liquid, 80% dimethomorph water dispersion granula, 3000 times of liquid, 80% S-Ethyl ethylthio sulfonate aqua, 1100 times of liquid, first frost dislike mould Lingshui Spring agent or Pu Like missible oil 750 times of liquid, standing grain power aqua 500 times of liquid, the pure particle of glucose analysis 1500 times of liquid, photosynthetic plain wetting powder 15000 times of liquid, Fish protein aqua 500 times of liquid, spray once every 3 days;
this phase, when there is insect pest, adds emamectin-benzoate aqua 1800 times of liquid with beta-cypermethrin aqua 1000 times of liquid and sprayed once every 3 days, or adopts Rynaxypyr missible oil 1000 times of liquid to spray once in every 9 days;
43) later stage medium seedling: during green onion seedling plant height 15 ± 2cm, with medicament benefit bacterium prestige wetting powder 750 times of liquid, 80% dimethomorph water dispersion granula, 1500 times of liquid, 80% S-Ethyl ethylthio sulfonate aqua, 1100 times of liquid, first frost dislike mould Lingshui Spring agent or Pu Like missible oil 750 times of liquid, standing grain power aqua 300 times of liquid, the pure particle of glucose analysis 1500 times of liquid, photosynthetic plain wetting powder 15000 times of liquid, Fish protein aqua 300 times of liquid, sprayed once every 3 days, separately added thiophanate methyl wetting powder 600 times of liquid every 9 days;
this phase, when there is insect pest, with beta-cypermethrin aqua 750 times of liquid, emamectin-benzoate aqua 1500 times of liquid, organosilicon aqua 500 times of liquid, sprayed once every 3 days; Or adopt Rynaxypyr missible oil 1500 times of liquid, within every 9 days, spray once;
44) seedlings are transplanted soon: cutting green onion leaf during 2-3 days before transplanting, namely carry out spray medicine after having cut green onion leaf, with medicament benefit bacterium prestige wetting powder 750 times of liquid, 80% dimethomorph water dispersion granula, 1500 times of liquid, 80% S-Ethyl ethylthio sulfonate aqua, 1100 times of liquid, first frost dislike mould Lingshui Spring agent or Pu Like missible oil 750 times of liquid, standing grain power aqua 250 times of liquid, the pure particle of glucose analysis 1500 times of liquid, Fish protein aqua 300 times of liquid, thiophanate methyl wetting powder 600 times of liquid;
this phase, when there is insect pest, sprays beta-cypermethrin aqua 600 times of liquid, emamectin-benzoate aqua 1000 times of liquid, organosilicon aqua 500 times of liquid; Or spray Rynaxypyr 750 times of liquid, organosilicon aqua 500 times of liquid, within every 9 days, spray once.
preferably, before described prevention method is also included in planting seed, Cotton seeds is carried out to naked seed: bactericide and insecticide are wrapped in naked seed surface, wherein, described bactericide is one or more the combination in metalaxyl-mn-zn, carbendazim, tmtd, and insecticide is Imidacloprid.
preferably, the photosynthetic element that the photosynthetic plain wetting powder adopted in step 4) is produced purchased from fertile magnificent agricultural science and technology (Jiangsu) limited company.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
1) change the conservative idea of traditional " sick ability laxative ", with " putting prevention first, anti-short combination ", effectively reduce the generation of damage by disease and insect;
2) microbial-bacterial fertilizer, standing grain power, S-Ethyl ethylthio sulfonate, glucose, beneficial bacterium prestige, photosynthetic element is used by adding, the effect killing pathogen can not only be realized, effectively can also promote the robust growth of green onion seedling, significantly improve self premunition of green onion seedling, and medicament mostly is green, biologic product, high-efficiency environment friendly;
3) by artificial neat seedling technical measures, while breaking green onion seedling apical dominance, nutrition is fully applied in green onion shoot root system and cross growth, green onion seedling significantly can be made to increase slightly, promote root growth, improve green onion seedling self drag.
Embodiment
below in conjunction with specific embodiment, technical scheme of the present invention is further elaborated.
a prevention method for shallot damage by disease and insect, concrete steps are as follows:
