Embodiment 1
[0029] A method for fertilizing crops against frost damage, the specific method is as follows:
[0030] (1) One week before the early frost in autumn, use a sprayer to spray clear water on the leaves of the plants once. If it catches up with rainy days, there is no need to spray water again. The purpose is to moisten the leaves of the plants and increase the water content of the plants;
[0031] (2) The next day after spraying water, get the plant antifreeze and mix it with water in a ratio of 1:80 by weight, and spray the plants at 6-8 o'clock in the morning; spray the plants again after sunset in the afternoon;
[0032] If it is rainy, you need to wait for the next day after the weather is clear to spray;
[0033] (3) After every other week, spray again in the morning and evening to strengthen the plants so that the antifreeze can adhere to the surface of the plants and form a protective film;
[0034] (4) Spray again sooner or later after the freezing damage occurs to reme...

[0043] A method for fertilizing crops against frost damage, the specific method is as follows:
[0044] (1) One week before the early frost in autumn, use a sprayer to spray clear water on the leaves of the plants once. If it catches up with rainy days, there is no need to spray water again. The purpose is to moisten the leaves of the plants and increase the water content of the plants;
[0045] (2) The next day after spraying water, get the plant antifreeze and mix it with water in a ratio of 1:80 by weight, and spray the plants at 6-8 o'clock in the morning; spray the plants again after sunset in the afternoon;
[0046] If it is rainy, you need to wait for the next day after the weather is clear to spray;
[0047] (3) After every other week, spray again in the morning and evening to strengthen the plants so that the antifreeze can adhere to the surface of the plants and form a protective film;

Abstract
Provided is a crop frost damage prevention fertilizing method, specifically comprising the followings: (1) a week before autumn early frost, using an atomizer to spray clear water once on plant leaf surfaces, if the weather is rainy, spraying water being not needed, an objective being humidifying plant leaf surfaces and making plant water content increased; (2) the second day after spraying water, using a plant antifreezing solution to uniformly mix with water according to proportion of weight ratio of 1 to 80, atomizing on plants at 6-8 o' clock; after sunset in the afternoon, atomizing on the plants again; if in a rainy day, spraying in the second day after the weather clears up; (3) after a week, spraying once respectively in the morning and evening, to enhance the plants, so the antifreezing solution can adhere on the surfaces of the plants and form a layer of protection film; (4) after freeze injury occurs, spraying once again in the morning and evening, to rescue plant freeze injury.
Description
technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for fertilizing crops to prevent freezing damage. Background technique [0002] In northern my country, the temperature often changes in early spring, late autumn and early winter, and crops are often invaded by cold waves due to sudden changes in the weather. The sharp drop in temperature caused severe freezing damage, which caused the loss of some tissues such as leaves and flowers. Even for some cold-resistant crops, the cold-resistant exercise in the crops had not been completed at the end of autumn, resulting in huge losses. [0003] The impact of freezing damage on crops is mainly caused by the freezing of plant cell spaces and plant cell freezing. When the temperature drops rapidly, the water in the cell spaces first freezes, and the water vapor in the surrounding cells flows into the ice crystals in the cell spaces. Coagulation increases the volume of ice ...
