Embodiment 1

[0039] A sports lawn antifreeze formulation 1 is shown below. The antifreeze is suitable for mowing the greens of golf courses frequently.

[0040] 1) 15% high fat film emulsion,

[0041] 2) Nutrient 12%,

[0042] 3) 0.8% of rare earth elements,

[0043] 4) Water retention antifreeze 5%,

[0044] 5) Growth regulator 1%,

[0045] 6) Penetrant 1%,

[0046] 7) Calcium chloride or calcium nitrate 0.2%,

[0047] 8) Distilled water 65%.

[0048] Production method: In the reaction kettle, first use sodium methoxide (CH 3 ONa) is a catalyst, which uses higher fatty acids to prepare a high-fat film emulsion through a catalytic reaction. Then in the reactor, the nutrient is complexed with lanthanum-rich rare earth, calcium chloride or calcium nitrate, and completely dissolved in water. Finally, the high-fat film emulsion and the nutrient are mixed according to a certain mass ratio, and after stirring uniformly, lanthanum-rich rare earth, glycerol, and polyvinyl alcohol are sequentially added. The...

Embodiment 2

[0052] A sports lawn antifreeze formulation 2 is shown below. The antifreeze is suitable for football field lawns in North China.

[0053] 1) 10% high-fat film emulsion,

[0054] 2) Nutrients 18%,

[0055] 3) Rare earth element 1%,

[0056] 4) Water retention antifreeze 5%,

[0057] 5) Growth regulator 1.5%,

[0058] 6) Penetrant 1%,

[0059] 7) Calcium chloride or calcium nitrate 0.5%

[0060] 8) Distilled water 63%.

[0061] Production method: same as Example 1.

[0062] How to use: Dilute this product by 600 times and spray it twice at an interval of 8-10 days. It can be used 1 to 2 months before the frost.

[0063] Effect of use: The lawn antifreeze prepared with the formula in Example 2 is used in multiple football fields in Shandong Province, and the lawn can turn green in early March. Until January of the next year, the annual green period can reach 310 days on average. Above; the plant does not wilt when it is below 0℃, and the rhizome can survive the winter safely at a low temperat...

Embodiment 3

[0065] A sports lawn antifreeze formulation 3 is shown below. The antifreeze is suitable for football field lawns in the relatively cold northeast region.

[0066] 1) 15% high fat film emulsion,

[0067] 2) Nutrient 12%,

[0068] 3) Rare earth element 1.6%,

[0069] 4) Water retention antifreeze 5%,

[0070] 5) Growth regulator 1.5%,

[0071] 6) Penetrant 0.3%,

[0072] 7) Calcium chloride or calcium nitrate 0.2%,

[0073] 8) Distilled water 64.4%.

[0074] Production method: same as Example 1.

[0075] How to use: Dilute this product 400 times and spray it 3 times at an interval of 5 to 7 days. It can be used 1 to 2 months before the onset of frost.

[0076] Use effect: The lawn antifreeze prepared with the formula in Example 3, after being used in multiple football fields in Jilin Province, the lawn's winter yellowing period becomes shorter, and the annual green period is extended to 260-280 days, which is longer than the original After 60 to 80 days, the lawn will turn green in late Marc...

Abstract

The invention provides a playground lawn anti-freezing agent and a preparation method thereof, and mainly aims at solving the problem that a ryegrass lawn in North China is difficult to live through the winter, becomes withered and yellow in winter and the like, and is capable of deferring the withering and yellowing and dormancy of the lawn and promoting the lawn to turn green and grow in advance, and thus effectively prolonging the green period of the lawn. The playground lawn anti-freezing agent comprises the following components: 10-15% of high-fat membrane emulsion, 12-18% of nutritional agent, 0.8-1.6% of rare earth element, 3-5% of water-retaining and anti-freezing agent, 1-1.5% of growth regulator, 0.5-1% of penetrating agent, 0.2%-0.5% of calcium chloride or calcium nitrate, and 60-70% of distilled water. A compound technical formula is adopted; the high-fat membrane emulsion in the formula is capable of forming a layer of air permeable thin film on the leaf surface of the lawn so that the water retention capacity of the lawn is improved, heat loss is avoided and harm caused by low temperatures to the lawn is effectively reduced; meanwhile, the nutritional agent, rare earth elements and the water-retaining and anti-freezing agent are added, and the penetrating agent is blended with the mixture. After the playground lawn anti-freezing agent is sprayed to the lawn, the permeability and the stability of the cell membranes of the lawn can be maintained, the contents of soluble sugar and free amino acids in cells can be quickly increased, and the heat storage capacity of cells is improved. The playground lawn anti-freezing agent has a physical anti-freezing effect and physiological anti-freezing effect.

Description

Technical field [0001] The invention relates to the technical field of plant antifreeze, in particular to a sports field lawn antifreeze and a preparation method thereof. Background technique [0002] The rise of the lawn industry is a sign of human civilization and social progress. my country's lawn industry has entered a new period of large-scale development. There are many types of lawn grasses with different characteristics. According to climatic conditions and the distribution of turfgrass area, turfgrass can be divided into warm season turfgrass and cold season turfgrass. Warm-season turfgrass mainly belong to the Gramineae family, and the optimum growth temperature is 25-30℃. Cool-season turfgrass, native to Northern Europe and Asia, grows at a temperature of 15-25℃, and is mainly distributed in North China and Northeast China. [0003] The rye grassland is produced in Germany and is a commonly used cold-season turfgrass species in northern my country. Its outstanding dro...
