Embodiment 1
[0022] A planting method of Datong grass, comprising the following steps:
[0023] Step 1, take the Chase grass seeds and wash them with water, dry them in the shade, take the shade-dried Chase grass seeds and soak them in the straw ash solution, apply ultrasound during the soaking process, and pass ozone into the straw ash solution;
[0024] The preparation method of the straw ash solution is as follows: calcining the straw at 180° C. to obtain the straw ash; adding a mixture of 50 g of the straw ash, 2 g of sodium hydroxide and 200 g of water into a supercritical device by weight, and heating the straw at a temperature of 380° C. Soak in a supercritical water system with a pressure of 22MPa for 60min, filter; take 10g of filtrate, 3g of 6wt% hydrogen peroxide solution, 2g of humic acid, 1g of tea polyphenols and 0.3g of ascorbic acid and mix uniformly to obtain a straw ash solution;
[0025] The ultrasonic process is as follows: put the straw ash solution and Chase grass see...

Embodiment 3
[0036] A planting method of Datong grass, comprising the following steps:
[0037] Step 1, take the Chase grass seeds and wash them with water, dry them in the shade, take the shade-dried Chase grass seeds and soak them in the straw ash solution, apply ultrasound during the soaking process, and pass ozone into the straw ash solution;
[0038] The preparation method of the straw ash solution is as follows: calcining the straw at 200° C. to obtain the straw ash; by weight, adding a mixture of 45 g of the straw ash, 2 g of sodium hydroxide and 240 g of water into a supercritical device, and heating it at a temperature of 385° C. Soak in a supercritical water system with a pressure of 23MPa for 60min, filter; take 13g of the filtrate, 4g of 6wt% hydrogen peroxide solution, 2.5g of humic acid, 1g of tea polyphenols and 0.3g of ascorbic acid and mix uniformly to obtain a straw ash solution;
[0039] The ultrasonic process is as follows: put the straw ash solution and Chase grass see...
