Embodiment 1

[0030] The following components are formulated by weight fraction ratio: film-forming agent (seaweed polysaccharide and polylactic acid with 1:1.5) 8%, sucrose 4%, antifreeze agent 14% (pentaerythritol and diethylene glycol are mixed with 1:5), Calcium nitrate 0.8%, micro-fertilizer 6%, vitamin (salicylic acid, choline and inositol mixed in 1:1:1) 0.4%, surfactant 1.2%, magnetized water 60%.

[0031] First, take a certain amount of water and place it in a magnetizer with a magnetic field strength of 1000mT for 4 hours to form magnetized water, then dissolve seaweed polysaccharide and polylactic acid in 900mL of magnetized water at 20-30°C at a ratio of 1:1.5, and add sugar in turn Classes and micro-fertilizers were reacted in a magnetizer for 60 minutes to form a uniformly mixed liquid; then the prepared antifreeze reagent was dissolved in 100mL of magnetized water at 40-60°C, and then antifreeze elements were added and stirred for 10 minutes until completely dissolved and adde...

Embodiment 2

[0033] This antifreeze is calculated by the following percentages by weight: film-forming agent (marine polysaccharide and polylactic acid with 1: 1.5) 8%, glucose 6%, antifreeze agent 16% (mannitol and diethylene glycol are mixed with 1: 5) ), calcium nitrate 1.2%, micro-fertilizer 5%, salicylic acid, choline (mixed at 1:1) 0.3%, growth regulator (maleic hydrazide) 1%, surfactant 1.2%, magnetized water 60%.

[0034] First, take a certain amount of water and place it in a magnetizer with a magnetic field strength of 1000mT for 4 hours to form magnetized water, then dissolve seaweed polysaccharide and polylactic acid in 900mL of magnetized water at 20-30°C in a ratio of 1:2, and then add them in sequence Sugar and micro-fertilizer are stirred in a magnetizer for 60 minutes to form a uniformly mixed liquid; then add the prepared antifreeze reagent and antifreeze element while stirring, and stir for 10 minutes until completely dissolved; finally add the measured surface Active a...

Embodiment 3

[0036] This antifreeze is calculated by following percentage by weight: film-forming agent (marine polysaccharide and polylactic acid with 1: 2) 8%, glucose 2%, sucrose 3%, antifreeze agent 16% (pentaerythritol, mannitol and diethylene glycol with 1:1:10 mixed), calcium nitrate 1.6%, micro-fertilizer 4%, vitamin (choline) 0.2%, growth regulator (maleic hydrazide, bijou, humic acid mixed in 2:1:1 Made) 2%, surfactant 2%, magnetized water 60%.

[0037] First, take a certain amount of water and place it in a magnetizer with a magnetic field strength of 1000mT for 4 hours to form magnetized water, then dissolve seaweed polysaccharide and polylactic acid in 900mL of magnetized water at 20-30°C in a ratio of 1:2, and then add them in sequence Sugar and micro-fertilizer are stirred in a magnetizer for 60 minutes to form a uniformly mixed liquid; then add the prepared antifreeze reagent and antifreeze element while stirring, and stir for 10 minutes until completely dissolved; finally ...

Abstract

The invention discloses a compound plant anti-freezing agent and a preparation method thereof, aiming at the problems of single function and short protection period of the traditional plant anti-freezing agent. The compound plant anti-freezing agent comprises the following ingredients: 8-12% of a film-forming agent, 4-6% of saccharide, 10-16% of an anti-freezing reagent, 0.8-1.6% of an anti-freezing element, 4-6% of a micro element fertilizer, 0.2-0.4% of vitamin, 0-2% of a growth regulating agent, 1.2-2% of a surfactant and 60% of magnetized water. The compound plant anti-freezing agent is characterized in that the magnetized water is used for replacing common water to improve the activity of the anti-freezing agent. On one hand, one layer of protective film can be formed on the surface of the plant so as to perform the functions of resisting cold, preventing freezing and reducing transpiration water loss. On the other hand, the content of saccharide in plant cells can be improved, the activity of plasma membrane ATP (adenosine tTriphosphate) enzyme is increased, the phenomena of freezing in cells and cell freezing dehydration are avoided, and therefore the influence on the plant by freezing injury is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of antifreeze for crops, in particular to a compound plant antifreeze and a preparation method thereof. Background technique [0002] In recent years, with global warming and the increase in the number of "late spring cold" in spring, the spring frost damage of plants has become increasingly serious. When the "cold in late spring" occurs, the winter wheat that is in the stage of turning green or jointing growth will suffer from different degrees of freezing damage. The cotton, rice and other crops that have been sown but not unearthed will have rotten seeds, and a large number of seedlings that have been unearthed will be frozen to death. There are many kinds of crops in my country with different growth characteristics. In the season of turning green, many seedlings are young and tender, and have not yet fully lignified. In the event of freezing and snowy weather, frost damage is very easy to occur. In mild...
