Composite capable of improving plant freezing resistance and preparation method thereof

Abstract

The invention belongs to the field of agriculture and particularly relates to a composite capable of improving plant freezing resistance and a preparation method thereof. The composite capable of improving plant freezing resistance is prepared from, by weight, 1-10% of amino acid, 0.1-1.2% of salicylic acid, 0.5-1.2% of diethyl aminoethyl hexanoate, 10-40% of cane sugar and the balance water. According to the composite capable of improving plant freezing resistance and the preparation method thereof, the preparation is simple, the composition is reasonable, after proline, arginine or sodium of polyaspartic acid and the cane sugar are absorbed by plants, the freezing resistance of the plants can be improved rapidly, the salicylic acid can maintain the freezing resistance of the plants for a long time by inducing a series of internal changes inside the plants, diethyl aminoethyl hexanoate and 5-aminolevulinic acid can promote vital movement and water absorption and fertilizer absorption capabilities of the plants under low temperature conditions, capabilities of the plants for being adapted and resisting to adverse environments such as low temperature freeze injury are improved, and harm of winter severe cold waves, late spring coldness and autumn early frost is avoided.

Description

(1) Technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a composition for improving plant frost resistance and a preparation method thereof. (2) Background technology [0002] With the shortening of the sunshine and the decrease of the temperature, a series of physiological and biochemical changes to adapt to the low temperature will occur in the plant to obtain cold resistance. However, when the cold wave suddenly hits the plants in late autumn or early spring, the plants have not yet undergone proper cold resistance training. Poor cold resistance; susceptible to frost damage. Freezing injury is an important limiting factor affecting the high yield of plants. In the process of plant growth and development, too low temperature will inhibit the normal development of plants, resulting in reduced production and income, and economic losses to growers. Therefore, improving plant frost tolerance is a technical problem that needs ...
