Cold-resistant nutritional agent for fruit trees and application thereof

Abstract

The invention relates to the technical field of fruit tree planting, in particular to a cold-resistant nutritional agent for fruit trees and application thereof. The cold-resistant nutritional agent for the fruit trees is prepared from 10-14 parts of amino acid, 6-10 parts of calcium fertilizer, 6-10 parts of potassium fulvate acid and 2-5 parts of salicylic acid. According to the cold-resistant nutritional agent for the fruit trees, all the raw materials are compounded according to a preferred ratio, so that mutual cooperation and promotion of all the raw materials are realized, so that the cold resistance of the fruit trees in the flowering and fruit setting period in spring can be obviously improved, the fruit setting percentage of the fruit trees after the fruit trees are attacked by the cold spell in later spring is remarkably increased, and therefore the yield is increased, and the economic benefits of fruit farmers are guaranteed.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a cold-resistant nutrient for fruit trees and an application thereof. Background technique [0002] my country is a country with a monsoon climate. During the transitional period from winter monsoon to summer monsoon around March, there are often intermittent cold air attacks from the northwest region, causing the temperature to rise and fall suddenly in spring, often appearing in the late spring. During the "Late Spring Cold" period, the temperature drops rapidly, and can quickly drop below 0°C or even rain and snow, which can last for 1 to 2 weeks. [0003] Late spring cold will have a very adverse impact on agricultural production. During the transition process of fruit trees from late autumn to midwinter, the plants gradually stop growing, shed leaves naturally, and enter dormancy through cold resistance exercise, gradually gaining the maximum cold resistance.

Problems solved by technology

[0005] Aiming at the problem that the late spring cold has a very adverse effect on the flowering and fruit setting of fruit trees, and the existing technology cannot effectively improve the cold resistance of fruit trees to the late spring cold during the flowering period, the present invention provides a fruit tree anti-cold nutrient
