Embodiment 1

[0017] The invention provides a preparation for preventing freezing damage of plants, which comprises sodium carboxymethyl cellulose, which accounts for 10%-15% by weight. ; Magnesium sulfate, 2% by weight; Potassium dihydrogen phosphate, 0.4% by weight; Sodium dodecylbenzene sulfonate, 2% by weight; the rest is water.

[0018] The preparation for preventing freezing damage of plants of the present invention can form a protective film on the surface of plants, improve the resistance of plants to low temperature freezing damage, and can effectively prevent freezing damage of plants.

[0019] The chemical formula of sodium carboxymethyl cellulose is [C6H7O2(OH)2CH2COONa] n (CMC), belongs to anionic cellulose ethers. The inventors' research and experiment found that using it as the main component of the preparation for preventing plant freezing damage of the present invention can effectively form a film on the surface of the plant and has good adhesion. In addition, mixing with the s...

Embodiment 2

[0021] The invention provides another preparation for preventing plant freezing damage, including sodium hydroxymethyl cellulose, which accounts for 10%-15% by weight. ; Magnesium sulfate, 2% by weight; Potassium dihydrogen phosphate, 0.4% by weight; Sodium dodecylbenzene sulfonate, 2% by weight; the rest is water.

[0022] The preparation for preventing freezing damage of plants of the present invention can form a protective film on the surface of plants, improve the resistance of plants to low temperature freezing damage, and can effectively prevent freezing damage of plants.

[0023] The chemical formula of sodium hydroxymethyl cellulose is Cell-O-CH2-COONa NaCMC. The inventor’s research and experiment found that using it as the main component of the preparation for preventing plant freezing damage of the present invention can effectively form a film on the surface of the plant with good adhesion. After being mixed with sodium dodecylbenzene sulfonate in an appropriate amount a...

Embodiment 3

[0025] The present invention also provides a method for preventing freezing damage to plants, which includes: first preparing an antifreeze preparation. The preparation method includes first dissolving sodium carboxymethyl cellulose in water, and adding magnesium sulfate and potassium dihydrogen phosphate after it is completely dissolved. Finally, it is added to 100% to form a mother liquor and placed in a container for later use. In addition, dissolve sodium dodecylbenzene sulfonate in water, add water to 100% to obtain sodium dodecylbenzene sulfonate solution, and place it in another container for later use. When in use, mix the two solutions into the sprayer and spray directly without special treatment. In the above preparation method, preferably, in the mother liquor prepared, the content of sodium carboxymethyl cellulose is 20%-30% by weight, the content of magnesium sulfate is 4% by weight, and the content of potassium dihydrogen phosphate is by weight 0.8%. The content...

Abstract

The invention provides a preparation for preventing freezing damage to plants. The preparation comprises, by weight, 10 percent of 15 percent of sodium carboxymethylcellulose or carboxymethyl cellulose sodium, two percent of magnesium sulfate, 0.4 percent of monopotassium phosphate, two percent of sodium dodecyl benzene sulfonate and the balance water. The invention further provides a method for preventing the freezing damage to the plants. The method comprises the steps that the antifreezing preparation is prepared, the sodium carboxymethylcellulose or the carboxymethyl cellulose sodium is firstly dissolved in the water, the magnesium sulfate and the monopotassium phosphate are added after the sodium carboxymethylcellulose or the carboxymethyl cellulose sodium is completely dissolved in the water, 100 percent of forming mother solutions are added, and the solutions are placed in a container for standby application; in addition, the sodium dodecyl benzene sulfonate is dissolved in the water, the water is added to reach 100 percent, sodium dodecyl benzene sulfonate solutions are obtained and placed in another container for standby application; in the use process, the two solutions are mixed and placed in a sprayer and are directly sprayed. According to the preparation and method for preventing the freezing damage to the plants, environment is not polluted, the preparation can be directly sprayed, the preparation and use method are simple, cost is low, the effect is good, and the freezing damage can be relieved fast even though the preparation is used after the freezing damage happens.

Description

Technical field [0001] The invention relates to the field of plant antifreeze, in particular to a plant antifreeze and a preparation method thereof. Background technique [0002] In northern my country, trees often suffer from freezing damage and other over-wintering damage, causing dryness or even death. Similar problems also occur in the introduction and cultivation of chestnut, hybrid hazelnut, apple and other fruit trees. In the cold of spring, apricot and pear trees often suffer from freezing damage to flower buds. In addition to breeding excellent varieties with strong frost resistance, it is also necessary to adopt appropriate anti-freezing measures for trees for comprehensive control. [0003] The existing methods of antifreeze for trees mainly include physical antifreeze and the use of plant antifreeze. In colder areas, tree trunks are used to wrap straw curtains, and the straw curtains are wrapped with plastic cloth to prevent freezing. This method is cumbersome to ope...
