Cold-resistant foliar fertilizer and preparation method thereof

Abstract

The invention discloses a cold-resistant foliar fertilizer and a preparation method thereof, the cold-resistant foliar fertilizer includes 10-15 parts of abscisic acid, 10-20 parts of chitosan, 20-30 parts of boric acid, 25-35 parts of potassium carbonate, 5-15 parts of epsilon-Poly lysine, 5-15 parts of humic acid, 10-30 parts of itaconic acid, 1.7-15 parts of trace elements, 0.1-0.5 part of Hexanoic,2-(diethylamino) ethyl estercitrate, 60-80 parts of water and 0.1-1 part of a chelating agent. The preparation method of the cold-resistant foliar fertilizer comprises the following steps: obtaining raw materials according to the components of the cold resistant foliar fertilizer; and stirring and mixing the obtained raw materials at 75-80 DEG C for 25 to 35min. The cold-resistant foliar fertilizer is directly applied to leaf of crops by spraying, the cold-resistant foliar fertilizer contains the most environmentally-sensitive exogenous hormone abscisic acid, and can quickly adjust the crops to change the metaboilic level to adapt to cold damage environment, and by use of various functional components, effects of low temperature on water in plants can be reduced, nutrients and nutritional components for promoting growth and metabolism can be supplemented, and the metabolic ability of the crops in low temperature environment can be maintained stably.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer preparation, in particular to a cold-resistant foliar fertilizer containing exogenous abscisic acid and a preparation method thereof. Background technique [0002] Chilling injury is a frequent global natural disaster. In agricultural production, temperature is a necessary condition for plant growth and the main limiting factor for the natural geographical distribution of plants. Planted agricultural or commercial crops can only grow and reproduce normally within a certain temperature range. For example, many plants cannot grow in northern or alpine regions because of the limitation of low temperature adversity. When crops suffer from chilling damage, in addition to the changes in external morphology, more importantly, it will delay the speed of a series of plant physiological activities, and even destroy their physiological functions. Physiological damage includes: cell membrane dama...

Problems solved by technology

[0004] However, during the application of the above fertilizers, based on their own mechanism, the fertilizer components do not directly affect the metabolism, but indirectly affect the degree of water / nutrient metabolism of the crops in the cold damage environment by affecting the product environment of crop metabolism. The cold efficiency is slow and the effect is not obvious; and it is applied to the soil medium and cannot be quickly and effectively absorbed by the crops
