Embodiment 1

[0028] The method for improving the cold resistance of grapes described in the present embodiment is taken as experimental material with potted grapes, comprising the following steps:

[0029] (1) Clean up dead and yellow leaves;

[0030] (2) Based on the calculation of 300 seeds per mu and 25 L of essential oil per mu, spray 0.8 L of reagent on each seed. The reagent components include: 2.5 parts of plant essential oil protection agent, 0.1 part of Tween 20, 97.4 parts of distilled water, wherein the plant essential oil protection agent includes 40 parts of trans-cinnamaldehyde, 30 parts of limonene, and 30 parts of carvacrol;

[0031] (3) Place the potted grapes at -4°C for two days.

[0032] Observing the freezing damage of grape plants, it was found that the grape plants sprayed with reagents were in good shape.

Embodiment 2

[0034] The method for improving the cold resistance of grapes described in the present embodiment is taken as experimental material with potted grapes, comprising the following steps:

[0035] (1) Clean up dead and yellow leaves;

[0036] (2) Based on the calculation of 300 seeds per mu and 25 L of essential oil per mu, spray 0.8 L of reagent on each seed. The reagent components include: 5 parts of plant essential oil protection agent, 0.2 part of Tween 20, 94.8 parts of distilled water, wherein, plant essential oil protection agent includes 35 parts of trans-cinnamaldehyde, 25 parts of limonene, and 40 parts of carvacrol;

[0037] (3) Place the potted grapes at -4°C for two days.

[0038] Observing the freezing damage of grape plants, it was found that the grape plants sprayed with reagents were in good shape.

Embodiment 3

[0040] The method for improving the cold resistance of grapes described in the present embodiment is taken as experimental material with potted grapes, comprising the following steps:

[0041] (1) Clean up dead and yellow leaves;

[0042] (2) Based on the calculation of 300 seeds per mu and 25 L of essential oil per mu, spray 0.8 L of reagent on each seed. The reagent components include: 7.5 parts of plant essential oil protective agent, 0.3 part of Tween 20, 92.2 parts of distilled water, wherein the plant essential oil protective agent includes 30 parts of trans-cinnamaldehyde, 20 parts of limonene, and 50 parts of carvacrol;

[0043] (3) Place the potted grapes at -4°C for two days.

[0044] Observing the freezing damage of grape plants, it was found that the grape plants sprayed with reagents were in good shape.

Abstract

The invention discloses a reagent for improving the cold resistance of grapes, which comprises the following components and the parts by volume of each component are: 2.5-7.5 parts of plant essential oil protective agent, 0.1-0.3 parts of Tween 20, and 93-98 parts of distilled water . The invention also provides a method for improving the cold resistance of grapes, which includes: cleaning dead and yellow leaves and cleaning the ground; uniformly spraying the above reagents on grape plants. The invention utilizes the natural green and environment-friendly plant essential oil protective agent, reduces the usage of chemicals and pesticides and reduces the pollution to the environment, improves the cold resistance of grapes, alleviates the problems of chilling injury and freezing injury caused by low temperature and season change, and achieves high yield. high quality.

Description

technical field [0001] The invention relates to a reagent and method for improving cold resistance of grapes and an application thereof, belonging to the technical field of viticulture. Background technique [0002] my country is one of the origins of grape plants and has a long history of viticulture. Grape is a fruit suitable for all ages. Its berries are rich in nutrients, and can prevent and treat neurasthenia, stomach pain, abdominal distension, and cardiovascular diseases. In addition to being eaten fresh, grapes are also an important raw material for the food industry, and can be used to make wine, raisins, grape juice and canned grapes. Grape is a woody vine hibernating fruit tree, and its cold resistance during the dormant period is limited. When the low temperature environment in winter in cold regions exceeds the limit of cold resistance, the plants will suffer from freezing damage. The cold resistance of different parts of grapes is different. Generally speakin...
