Plant anti-freezing fertilizer and preparation method thereof

Abstract

The invention relates to a plant anti-freezing fertilizer and a preparation method thereof. The plant anti-freezing fertilizer is composed of amino acids and / or humic acid and is characterized by comprising astaxanthin. The anti-freezing fertilizer can inhibit the growth of ice nucleating bacteria and fungi, destroy the ice nucleating proteins, and obviously enhance the low temperature resistant performance of plants.

Description

technical field [0001] The invention relates to a plant antifreeze fertilizer and a preparation method thereof. Background technique [0002] Frost is a relatively common agricultural meteorological disaster, which refers to a sudden drop in air temperature and a sudden drop in surface temperature below 0°C, causing damage to or even death of crops. Usually appear in autumn, winter and spring. [0003] When plants are damaged by freezing, the leaves are like scalded, the cells lose turgor, the tissues become soft, the leaves turn brown, and eventually dry up and die. [0004] The main cause of plant freezing damage is ice crystal damage, including extracellular icing and intracellular icing: extracellular icing is also called intercellular icing, which means that when the temperature drops, the water in the intercellular space and near the cell wall freezes; Internal icing refers to the rapid drop in temperature, in addition to intercellular icing, the water in cells also ...

AI Technical Summary

Problems solved by technology

[0006] Because ice-nucleating bacteria and fungi have high activity at low temperatures, and enzymes and beneficial microorganisms have extremely low activity at low temperatures, they cannot inhibit the growth of ice-nucleating bacteria. However, the use of pesticides for sterilization can kill ice-nucleating bacteria and fungi , but it will cause some damage to the ecological environment, and there may be pesticide residues, which will affect food safety
