Problems solved by technology

But the ripening of grapes is mostly in the hot and rainy season, and many varieties often suffer from fruit cracking diseases, resulting in a decline in commodity value and serious losses to producers. Therefore, it is of great significance to develop medicaments for preventing and controlling grape cracking

Embodiment 1

[0016] Grape anti-cracking fruit preparation is made up of following material (weight): gibberellin 0.3%, CaCl 2 25.7%, KCl22%, compound amino acid 10%, Tween-20 2% and water 40%.

[0017] Preparation: Put the compound amino acid into water, mix well and heat until the temperature is 80°C, then add CaCl in turn 2 and KCl, stirring continuously, until CaCl 2 Dissolve completely with KCl, incubate at 80°C for 60 minutes, then add gibberellin and Tween-20 in turn after cooling down to room temperature, and stir evenly; among them, gibberellin is first dissolved with absolute ethanol.

Embodiment 2

[0019] Grape anti-cracking fruit preparation is made up of following material (weight): gibberellin 0.1%, CaCl 2 25%, KCl 21%, compound amino acid 7.9%, Tween-20 2% and water 44%.

[0020] Preparation: Put the compound amino acid into water, mix well and heat until the temperature is 85°C, then add CaCl in turn 2 and KCl, stirring continuously, until CaCl 2 Dissolve completely with KCl, keep warm at 85°C for 40 minutes, then add gibberellin and Tween-20 in turn after cooling down to room temperature, stir evenly; among them, gibberellin is first dissolved with absolute ethanol.

Embodiment 3

[0022] Grape anti-cracking fruit preparation is made up of following material (weight): gibberellin 0.2%, CaCl 2 28%, KCl 20%, compound amino acid 6%, Tween-20 3% and water 42.8%.

[0023] Preparation: Put the compound amino acid into water, mix well and heat until the temperature is 82°C, then add CaCl in turn 2 and KCl, stirring continuously, until CaCl 2 Dissolve completely with KCl, keep warm at 82°C for 50 minutes, then add gibberellin and Tween-20 in turn after cooling down to room temperature, and stir evenly; among them, gibberellin is first dissolved with absolute ethanol.

Abstract

Disclosed are a grape berry dehiscence resisting preparation and a preparation method and an applying method thereof. The grape berry dehiscence resisting preparation comprises, by weight, 0.1-0.3% ofgibberellin, 25-28% of CaCl2 (calcium chloride), 20-22% of KCl (kalium chloratum), 6-10% of compound amino acid, 2-4% of Twain-20 and 40-44% of water. The preparation method includes: adding the compound amino acid into the water, mixing evenly, heating till a temperature reaches to 80-85 DEG C, successively adding the CaCl2 and the KCl, stirring continuously till the CaCl2 and the KCl are dissolved completely, keeping the temperature at 80-85 DEG C FOR 40-60 minutes, cooling to a normal temperature, adding the gibberellin and the Twain-20 successively, and stirring evenly at last. By diluting the grape berry dehiscence resisting preparation by 100 times and soaking ripening grape berries for five seconds, coordinated growth of grape skins and grape pulp can be promoted by the gibberellin, formation of protein and cellulose in the grape skins can be promoted by kalium elements, formation of a large amount of pectic acid in the grape skins can be promoted by calcium elements, so that toughness of the grape skins is enhanced, and dehiscence resistance is enhanced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to an anti-cracking grape preparation, as well as a preparation method and an application method of the anti-cracking preparation. Background technique [0002] Grapes are deeply loved by people because of their rich nutrition and delicious taste. In my country, they are mainly eaten fresh. However, grapes are often matured in hot and rainy seasons, and fruit cracking diseases often occur in many varieties, resulting in a decline in commodity value and serious losses to producers. Therefore, it is of great significance to develop medicaments for preventing and controlling grape cracking. [0003] Gibberellin can accelerate the elongation of cells and promote the division of cells. It can promote the rapid growth of pericarp when it is used in the period of rapid fruit expansion. Potassium is a physiological activator of various enzymes in plants. Appropriate potassium concentratio...
