A kind of multifunctional anti-low temperature preparation for fruit trees and preparation method thereof

Abstract

The invention is specifically a multi-functional anti-low temperature preparation for fruit trees and a preparation method thereof, which solves the problem that the current anti-low temperature preparation for fruit trees is in a blank state and the stability agent is used to indirectly increase stress resistance. A multi-functional anti-low temperature preparation for fruit trees, which is composed of the following components in parts by weight: 58-63 parts of biochemical fulvic acid, 270-285 parts of calcium chloride, 8-11 parts of salicylic acid, and 4 parts of diethyl hexanoate ‑6 parts, 15‑20 parts of ethanol, 9‑11 parts of glycerin, 600‑620 parts of water. The present invention not only contains body nutritional components; also contains chemical regulators and chelated Ca2+ and other active ingredients that directly act on the antifreeze mechanism of cells to change, effectively improving the antifreeze performance of fruit trees; Antifreeze and prevention of physiological diseases caused by calcium deficiency also have good effects, such as the prevention and treatment of peach tree fruit suture softening and pear tree chicken foot disease.

Description

technical field [0001] The invention relates to the low temperature resistance technology of crops, in particular to a multifunctional anti-low temperature preparation for fruit trees and a preparation method thereof. Background technique [0002] The average annual frost damage area in my country reaches 340,000 km², and the heaviest year reaches 770,000 km², causing annual losses of crops, fruit trees and vegetables to reach 3 billion yuan. Especially in recent years, late frost damage has been particularly serious in northern my country. Some fruit trees that bloom early in spring often encounter late frost damage. The light ones reduce production, and the severe ones fail to harvest. In some areas, late frost damage has become a limiting factor for the development of fruit trees. [0003] In order to prevent and reduce the harm of late frost in the flowering period of fruit trees, scientific researchers have carried out many studies. At present, the product with the mos...
