A preparation for treating tomato cracking and its preparation method and application

Abstract

The invention discloses a preparation for treating dehiscent fruit of tomatoes as well as a preparation method and application for the preparation, and belongs to the technical field of vegetable growth regulators. The preparation comprises the following raw materials in parts by weight: 15,000 parts of water, 15 to 20 parts of a sodium borate aqueous solution, 3 to 8 parts of a pyrazole lung alcohol solution or gibberellins A4+7 solution, and 15 to 20 parts of ammonium calcium nitrate, wherein in the pyrazole lung alcohol solution, pyrazole lung and alcohol are mixed in a weight ratio of (0.05-0.2):100; in the gibberellins A4+7 solution, gibberellins A4+7 and alcohol are mixed in the weight ratio of (0.05-0.2):100. The preparation for treating the dehiscent fruit of the tomatoes disclosed by the invention can effectively prevent and treat the dehiscent fruit and leaf curl of the tomatoes.

Description

technical field [0001] The invention relates to a preparation for treating tomato fruit cracking, a preparation method and application thereof, and belongs to the technical field of vegetable growth regulators. Background technique [0002] Tomato fruit cracking disease is a common physiological disease that harms tomato fruit, 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 culti...

Problems solved by technology

[0003] At present, there is no better solution for tomato cracking: First, the prior art involves anti-cracking methods for grapes, but the nutrient solution suitable for grapes is directly applied to tomatoes so that the effect is not ideal

Tomatoes are obviously larger than grapes in terms of fruit size. The average diameter of grapes is 1.53cm. Except for a few small fruit tomatoes (such as cherry tomatoes), the diameter of tomatoes can reach 7~10cm. Compared with grapes, tomatoes can be harvested in a short time. The internal volume increases rapidly, especially for large tomato varieties. It is difficult to eliminate the fruit cracking disease of tomatoes with the existing grape anti-cracking nutrient solution

Tomato cracking disease will cause cracks on the surface of the fruit skin, and the selling price is less than one-third of that of normal-looking tomatoes. When a large number of cracked tomatoes appear in the tomatoes harvested by vegetable farmers, it will bring great losses to the income of vegetable farmers

Secondly, in the prior art, tomatoes of thick-skinned varieties are often used to solve the problem of fruit cracking, but compared with thin-skinned tomatoes, thick-skinned tomatoes have thick and hard skins, and the taste is not ideal, which affects sales.
