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:
[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:
[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:
[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 cold resistance of grapes. The reagent comprises the following components in parts by volume: 2.5-7.5 parts of a plantessential oil protective agent, 0.1-0.3 part of Tween 20 and 93-98 parts of distilled water. The invention also provides a method for improving the cold resistance of the grapes. The method comprises the steps: cleaning dead leaves and yellow leaves and cleaning the ground; and uniformly spraying the reagent to grape plants. According to the invention, a natural green environment-friendly plantessential oil protective agent is utilized, the usage amount of chemicals and pesticides is reduced, the pollution to the environment is reduced, the cold resistance of grapes is improved, and the problems of cold damage and freezing damage caused by low temperature and season alternation are alleviated, so that high yield and high quality are achieved.
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...
