Embodiment 1

[0027] Add 10g of fulvic acid, 40g of potassium dihydrogen phosphate, and 4g of ascorbic acid in 100mL of water in sequence, and then add 60mL of 0.5% aqueous solution of Artemisia annua seed glue, and finally add water to 1000mL, and mix well to obtain the cold resistance agent. The same method as in Example 1 was used to process Longyou No. 9 rape. Tests showed that compared with the control without anti-cold spray, the electrical conductivity decreased by 15.8%, the moisture content increased by 9.6%, and the chlorophyll content increased by 0.07%. It indicated that the cold resistance of rapeseed seedlings had a small degree of improvement.

Embodiment 2

[0029] Weigh 7 g of crushed Nitraria tangutica fruit and add it to 100 mL of water, extract in a water bath at 70°C for 9 hours, filter and centrifuge to obtain the water extract of Nitraria tangutica fruit. Add 8g of fulvic acid, 30g of potassium dihydrogen phosphate, 2g of ascorbic acid in turn to the water extract of Nitraria tanguta fruit, then add 30mL of 0.5% aqueous solution of Artemisia annua seed gum, and finally add water to 1000mL, and mix well to obtain the anti-cold agent . The same method as in Example 1 was used to process Longyou No. 9 rape. Tests showed that compared with the control group that was not sprayed with anti-cold agents, the electrical conductivity decreased by 25.0%, the water content increased by 17.4%, and the chlorophyll content increased by 2.4%. It shows that the cold resistance of rapeseed seedlings has been improved to a certain extent.

Embodiment 3

[0031] Weigh 8g of crushed seabuckthorn leaves, add them to 100mL of water, extract in a 70°C water bath for 10 hours, filter and centrifuge to obtain seabuckthorn leaf water extract, add 4g of fulvic acid and 40g of potassium dihydrogen phosphate to the seabuckthorn leaf water extract in sequence , 4g of ascorbic acid, plus 50mL of 0.5% Artemisia annua seed gum aqueous solution, and finally add water to 1000mL, and mix well to obtain the anti-cold agent. The same method as in Example 1 was used to process Longyou No. 9 rape. The test showed that compared with the control group without spraying cold resistance agent, the electrical conductivity decreased by 27.6%, the moisture content increased by 28.1%, and the chlorophyll content increased by 2.3%, indicating that the cold resistance of rapeseed seedlings has improved to a certain extent.

Abstract

The invention discloses an environment-friendly plant cold-resistant agent. The plant cold-resistant agent comprises the following components in parts by weight: 2 to 8 parts of hippophae rhamnoides, 2 to 8 parts of nitraria tangutorum bobr fruits, 20 to 60 parts of an aqueous solution of artemisia desertorum seed gum, 2 to 10 parts of fulvic acid, 20 to 40 parts of monopotassium phosphate and 2 to 4 parts of ascorbic acid. The invention also discloses a preparation method and application of the plant cold-resistant agent. The cold-resistant agent is a natural and environment-friendly preparation which does not pollute the environment, so that the side effect of pesticide residues caused by synthetic chemical pesticide is solved.

Description

technical field [0001] The invention relates to the technical field of frost prevention for crops, in particular to a green and environment-friendly plant anti-cold agent. Background technique [0002] Low temperature freezing damage is a serious natural disaster for plants, and it is the main factor that limits the natural distribution of plants and cultivation zones. Low temperature affects the growth and metabolism of plants, causing changes in plant-related physiological indicators, resulting in plant damage and reduced production. cause plant death. In modern agricultural production, most of the prevention and control of crop freezing damage is controlled by artificially synthesized chemical pesticides. Although most of them can achieve good control effects, the side effects of pesticide residues are also very serious. Therefore, it is very necessary to develop a green and environmentally friendly plant antifreeze agent to improve the cold resistance of plants and redu...
