Summary of the invention

Goal of the invention: the purpose of this invention is to provide a kind of grape management method that is beneficial to fruit thinning, thereby be beneficial to the grape fruit thinning and improve product quality and production efficiency.

Technical scheme: be to realize above-mentioned purpose, of the present invention a kind of grape management method that is beneficial to fruit thinning is provided, this method comprises: carry out dipping in the first time and soak inflorescence in grape first half of the month of blooming; , the grape flower fringe carries out dipping in the second time when having 1/2 ~ 3/4 to bloom soaking inflorescence; After solid, every fruit ear of dipping at a distance from 10 ~ 15 days.

The present invention adopts plant growth regulator---and gibberellin carries out twice inflorescence to grape to be dipped, and one time fruit ear is dipped, and is intended to make the grape flower fringe to grow, elongate, and prevents the too intensive fruit thinning difficulty that causes of fruit grain.Dip inflorescence the said first time and dip for the second time inflorescence and adopt gibberellin, Fluoxastrobin, Difenoconazole to mix to convert water logging and dip in; The said fruit ear of dipping adopts gibberellin, CPPU, Fluoxastrobin, Difenoconazole mixing to convert water logging and dip in.

Saidly dip in that to soak the gibberellin concentration that is adopted be 10 ~ 50mg/L.As further optimization of the present invention, dip in the said first time to soak and be 13.3mg/L, dip in to soak for the second time and be 40mg/L.Said gibberellin is that the dilution of 20% gibberellic acid crystalline flour obtains.

Said CPPU is the aqueous solution of concentration 666mg/L.

Said Fluoxastrobin adopts 25% kresoxim-methyl suspending agent (1500 times), and said Difenoconazole adopts 20% Difenoconazole water dispersant (3000 times).

Dip inflorescence the said first time, for the second time dip inflorescence, dip fruit ear all before at 9 in the morning, dip inflorescence after at 4 in afternoon.

The present invention also controls the growth of grape branch through the quantity of control inflorescence.Bloom and carried out the Hua Sui arrangement in preceding 10 days, every branch keeps 1 a string of flowers fringe, removes secondary fringe, and it is some that minor matters are respectively removed in the inflorescence upper and lower, and 5 ~ 6cm is long in the middle of keeping.The grape flower fringe carries out pinching to young sprout when first the flowers are in blossom, makes the blade that stays after the pinching be about into 1/3 size of blade in age; The following sublateral shoot of Hua Sui all removes, and the above sublateral shoot of flower fringe stays leaf pinching without offspring; Repeatedly pinching of sublateral shoot to newly growing later on, strict control was nourished and grown prosperous.

Beneficial effect: the workload that a kind of grape management method that is beneficial to fruit thinning of the present invention is saved the grape fruit thinning greatly, with regard to the management amount in 2000 jin of grape orchards, can save 10 working days; Simultaneously,, guaranteed of the rich nutrition of vine body at young fruit expanding stage in future owing to, avoided unnecessary inflorescence to consume the vine body nutrient accumulation of last one year fast in early days to the quantity control of inflorescence, help fruit form, expand, painted.

Embodiment

Bloom and carried out the Hua Sui arrangement in preceding 10 days, every branch keeps 1 a string of flowers fringe, removes secondary fringe, and it is some that minor matters are respectively removed in the inflorescence upper and lower, 5 ~ 6cm length in the middle of keeping.
