Embodiment 1

[0039] Taking the plant antifreeze agent of the present invention as an example for camphor trees to illustrate the antifreeze effect.

[0040] In a certain area where Cinnamomum camphora moves northward, the east longitude is 117.2 degrees, and the north latitude is 34.3 degrees. During the test period, winter was selected for a total of 75 days. The average temperature during the test period was 2.5°C, the lowest temperature was -10°C, and the highest temperature was 7°C.

[0041] Divide 156 camphor plants of ￠20-30cm on the same road section in this area into 6 groups, 26 plants in each group, marked as Group I, Group II, Group III, Group IV, Group V, and Group VI , starting from November 15, each group of camphor was sprayed evenly with the antifreeze 0 times, 1 time, 2 times, 3 times, 4 times, 5 times, and sprayed once every 15 days.

[0042] The test results were checked on January 30 of the following year, and it was found that the leaves of the entire canopy of group ...

Embodiment 2

[0044] Take the plant antifreeze of the present invention as an example to illustrate the antifreeze effect of osmanthus fragrans and Mediterranean viburnum.

[0045] In a certain area where sweet-scented osmanthus and Mediterranean viburnum are planted, the east longitude is 117.2 degrees, and the north latitude is 34.3 degrees. The test period was selected in winter, a total of 31 days, the average temperature of the test period was 2°C, the lowest temperature was -12°C, and the highest temperature was 4°C.

[0046] Select a certain road section where two kinds of plants are planted in this area to do the experiment. From December 1st, spray once every 10 days. To January 1st of the next year, the plots that will be continuously sprayed three times with this antifreeze agent will be compared with those without The plots sprayed with antifreeze were used for comparison.

[0047] The leaves of osmanthus sprayed with antifreeze are green and there is basically no frost damage,...

Abstract

The invention discloses a plant antifreezer and its preparation method. The plant antifreezer is preparegggggd from the following components of: by weight, 0.5-0.97% of glucose, 0.5-0.97% of cane sugar, 0.2-0.5% of potassium dihydrogen phosphate, 0.18-0.21% of novel monomolecular lipid film, 0.06-0.17% of paclobutrazol, 0.2-0.33% of amino acid, 0.02-0.05% of 6-benzylamino-purine, 0.01-0.05% of rapin, 46-48.4% of glycerin and 48.6-51% of water. The plant antifreezer provided by the invention is nontoxic and harmless, doesn't pollute the environment, and can be directly sprinkled on plant leaf surfaces, flowers and flower bus. The preparation method is simple and requires low cost. Effective antifreezing period can reach 15-20 days. By the adoption of the plant antifreezer, lower temperature freeze injury resistance of plants can be enhanced and the freeze injury can be rapidly mitigated after freeze injury. The plant antifreezer provided by the invention can be used to form a protection film on the surface of a plant and protect the plant from cold, and has an effect of preventing diseases.

Description

technical field [0001] The invention relates to a plant antifreeze agent and a preparation method thereof, which has the advantages of physical antifreeze and chemical antifreeze, belongs to a compound antifreeze agent, and is especially suitable for winter protection of southern tree species such as "south trees move north" in landscaping projects keep warm. Background technique [0002] In recent years, landscaping has been strengthened with people's ecological concepts and sustainable development concepts, and "moving trees from south to north" has become a trend and trend. In the process of "moving trees from south to north", although certain achievements have been achieved in some aspects, the severe winter in northern cities has become an important factor restricting "moving trees from south to north". After being transplanted to the north, many southern tree species generally grow poorly or even die due to the impact of freezing damage. This not only affects the land...
