Fruit crack preventive and application thereof

Abstract

The invention relates to a fruit crack preventive and an application thereof and belongs to the technical field of crop growth regulators. The fruit crack preventive is characterized by containing thefollowing components in parts by weight: 10 parts of compound amino acid, 0.12-0.18 part of gibberellin A4+7 or gibberellin A3, 0.7-1.3 parts of vitamin D3 and 0.015-0.15 part of 6-benzylamine adenine, wherein the compound amino acid is a mixture of tyrosine and lysine. The fruit crack preventive is sprayed to full plants in use before a fruit expansion stage. By utilizing the fruit crack preventive, cracked fruits of melons and fruits can be effectively prevented and treated. By adding vitamin D3 and compound amino acid in a formula of a preparation of the fruit crack preventive for cooperative use, the tenacity of peel of the melons and the fruits can be widely and effectively improved, and the fruit crack preventive has a good fruit crack prevention effect.

Description

technical field [0001] An anti-cracking agent and its application belong to the technical field of crop growth regulators. Background technique [0002] Fruit cracking disease is a common physiological disease that harms fruits, and it is easy to occur during the fruit veraison period. Protected land and open field cultivation can be harmful. After the fruit cracks, the fruit will be reduced or lose its commodity value. According to the location and shape of occurrence, it can be divided into three types: one is radial cracking, which is radially centered on the fruit pedicle, and the cracks are generally deep; The third is strip-shaped cracking, that is, irregular strip-shaped cracks at the top of the fruit. After fruit cracking occurs, the quality of the fruit declines, and pathogens are easy to invade, resulting in rot. In terms of cultivation types, the tomatoes cultivated in the open field in summer and the tomatoes cultivated in plastic film greenhouses in autumn h...

Problems solved by technology

eventual rupture of the peel

[0004] Fruit cracking causes serious economic losses to growers: Take honey pomelo as an example, the price of the intact fruit is 4 yuan to 13 yuan, and the price of cracked fruit is 0.05 yuan to 0.2 yuan

Grapes, depending on the variety, sell for 4 to 10 yuan with complete peels. However, due to the structure of grapes, the flesh will be polluted after the fruit is cracked, and the fruit will be inedible, and the cracked fruit has no economic value.
