A kind of above-mentioned method of preventing and treating Hei Baladuo grape fruit dehiscent fruit, specifically comprises the following steps:

1) before Hei Baladuo grape is bloomed 7 days to initial bloom stage, spend fringe shaping, dredge some stalk little Hua fringes of the secondary fringe of the fringe of deflorating and topmost, retain Hua Sui middle and lower part and prop up stalk little Hua fringe, and give birth to 7 centimetres to 9 centimetres of colored cob length of stalk little Hua fringe, prop up stalk little Hua cob length and be no more than 3 centimetres, exceed 3 centimetres of parts and bounce back;

2) after grape fallen flowers after approximately 14 days, after confirming that grape is beared fruit, each root young sprout fringe of selecting and remain is beared fruit evenly, and fruit grain size is basically identical, and the good fruit ear of fruit ear fringe type, by all the other fruit ears removals;

3) determine fruit ear and finish, after grape fallen flowers, after approximately 21 days, carry out in time fruit thinning grain, produce high-quality black Ba Laduo grape, each fruit ear weight is taking 400 grams to 500 grams as standard, and each fruit ear stays 45 to 55 of fruit grains, and it is 6 to 8 that average every 1 centimetre of fruit ear shaft length raw fruit granule density;

4) after fruit thinning burl bundle, spraying low toxicity highly effective pesticide in time, cover grape bag special;

5) after grape germinates, when young sprout grows to 12 blades, carry out pinching for the first time, after pinching, make top sublateral shoot continued growth, regrowth 5 leaf pinching, after pinching, then make top sublateral shoot continued growth, regrowth 5 leaf pinching, other sublateral shoot stays 2 leaf pinching, and by even grape young sprout colligation on frame face;

6) after grape maturity, gather.

Beneficial effect: the method spends cob long to the shaping of flower fringe, control before blooming by grape; Grape bear fruit after fruit ear dredge grain, control fruit ear axial length and raw fruit granule density, make fruit grain in the process of expanding, not extruding mutually between fruit grain, control grape fruit generation dehiscent fruit.The method by flower fringe shaping, determine fringe and dredge grain, the standardized managements such as cover grape bag special and Tipping, make fruit grain raw even, fruit ear outward appearance is gorgeous, has stablized vintage, has improved grape quality.

Embodiment

Below in conjunction with embodiment, further set forth the present invention.

Embodiment 1:

A method of preventing and treating Hei Baladuo grape fruit dehiscent fruit, specifically comprises the following steps:

1) before Hei Baladuo grape is bloomed 7 days to initial bloom stage, spend fringe shaping, dredge some stalk little Hua fringes of the secondary fringe of the fringe of deflorating and topmost, retain Hua Sui middle and lower part and prop up stalk little Hua fringe, and give birth to 9 centimetres of colored cob length of stalk little Hua fringe, prop up stalk little Hua cob length and be no more than 3 centimetres, exceed 3 centimetres of parts and bounce back;

3) determine fruit ear and finish, after grape fallen flowers, after approximately 21 days, carry out in time fruit thinning grain, produce high-quality black Ba Laduo grape, each fruit ear weight is taking 500 grams as standard, and each fruit ear stays 55 of fruit grains, and it is 8 that average every 1 centimetre of fruit ear shaft length raw fruit granule density;
