Composition for improving plant frost resistance and preparation method thereof

Abstract

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. The composition for improving plant frost resistance is made of the following components in weight percentage: 1-10% of amino acid, 0.1-1.2% of salicylic acid, 0.5-1.2% of diethyl diethylhexanoate, 10-40% of sucrose, and the balance for water. The composition for improving plant freeze resistance and the preparation method thereof are simple in preparation and reasonable in composition, and after the proline, arginine or polyaspartic acid and sucrose are absorbed by the plant, the freeze resistance of the plant can be rapidly improved, and the water By inducing a series of changes in plants, sycylic acid can maintain the plant's frost resistance for a long time. Diethyl hexanoate and 5-aminolevulinic acid can promote the life activities of plants and the ability to absorb water and fertilizer under low temperature conditions, and improve the plant's ability to absorb water and fertilizer. Adaptation and resistance to adverse environments such as low temperature and freezing damage, avoiding the harm of strong cold wave in winter, cold in late spring and early frost in autumn.

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 ...
