Embodiment 1

[0039] A sports field turf antifreeze formulation 1 is shown below. This antifreeze is suitable for lawns in the green areas of golf courses that are mowed more frequently.

[0040] 1) High lipid film emulsion 15%,

[0041] 2) Nutrients 12%,

[0042] 3) Rare earth element 0.8%,

[0043] 4) 5% water-retaining antifreeze,

[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 reactor, firstly use sodium methoxide (CH 3 ONa) is used as a catalyst to prepare a high-fat film emulsion by using a higher fatty acid through a catalyzed 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 nutritional agent are mixed according to a certain mass ratio, and after stirring evenly, lanthanum-rich rare earth, gl...

Embodiment 2

[0052] A sports field turf antifreeze formula 2 is shown below. The antifreeze is suitable for football field turf in North China.

[0053] 1) High lipid film emulsion 10%,

[0054] 2) Nutrients 18%,

[0055] 3) Rare earth element 1%,

[0056] 4) 5% water-retaining antifreeze,

[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 600 times and spray it twice, with an interval of 8-10 days between each time. It can be used 1-2 months before the frost comes.

[0063] Effect of use: The lawn antifreeze prepared by the formula in Example 2, after being used in many football fields in Shandong Province, the lawn can turn green in early March until January of the next year, and the annual green period can reach 310 days on average above; the plants will not wither when below 0°C, and the rhizomes...

Embodiment 3

[0065] A sports field turf antifreeze formulation 3 is shown below. The antifreeze is suitable for football field turf in the colder northeast region.

[0066] 1) High lipid film emulsion 15%,

[0067] 2) Nutrients 12%,

[0068] 3) Rare earth element 1.6%,

[0069] 4) 5% water-retaining antifreeze,

[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 with an interval of 5 to 7 days. It can be used 1 to 2 months before the frost comes.

[0076] Application effect: the lawn antifreeze prepared by the formula in Example 3, after being used in many football fields in Jilin Province, the lawn withered yellow period in winter shortened, and the annual green period was extended to 260-280 days, compared with the original, the extension After 60-80 days, the law...

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 an antifreeze agent for sports field lawns and a preparation method thereof. Background technique [0002] The rise of the turf industry is a symbol of human civilization and social progress, and the turf industry in my country has entered a new period of large-scale development. There are many types of turfgrasses with different characteristics. According to climatic conditions and geographical distribution of turfgrass, turfgrass can be divided into warm-season turfgrass and cool-season turfgrass. Warm-season turfgrass mainly belongs to Poaceae, and the optimum growth temperature is 25-30°C. Cool-season turfgrass, native to Northern Europe and Asia, grows at a suitable temperature of 15-25°C, and is mainly distributed in North China and Northeast China. [0003] Ryegrass is produced in Germany and is a commonly used cool-season turfgrass species in northern my count...
