[0037] A method for preparing an electricity-generating regulator for sorghum includes the following steps:

[0038] S1. Indole-3-acetic acid, kinetin, gibberellin and abscisic acid are mixed into a polyvinyl alcohol aqueous solution and fully mixed using magnetic stirring. During the mixing process, a sodium alginate aqueous solution is added until microspheres with a diameter of 10 to 50 μm are formed, and then the magnetic stirring is stopped and the microspheres are transferred to a calcium chloride solution for solidification for 1 to 2 hours to obtain plant hormone microparticles;

[0039] S2. urea, superphosphate, potassium chloride and chelated zinc are mixed into deionized water and mixed thoroughly using magnetic stirring, glutamic acid and fulvic acid are added during the mixing process, and ultrasonic treatment is performed for 10 to 15 minutes to obtain a plant nutrient solution;

[0042] It should be noted that in step S1, the mass fraction of the polyvinyl alcohol aqueous solution is 5-6%, and the mass fraction of the sodium alginate aqueous solution is 6-8%;

[0043] In step S2, the temperature of the deionized water is 60-80°C;

[0044] In step S2, the power of ultrasonic treatment is 150-200W;

[0047] Sorghum is irrigated with brackish water with a mineralization of 0.71 g / L under the membrane. The specific irrigation system is shown in the following table:

The specific method is to use a hand-pressure spraying pot to spray evenly on the leaves of sorghum (both sides), spray until there are tiny droplets on the leaf surface, spray after 16:00 on a sunny day or on a cloudy day, and spray again if it rains within 4 hours after spraying;

[0052] It should be noted that after sowing, the position of the drip tape and the forage sowing point should be adjusted in time, and the drip tape should be checked for damage and whether the dripper can discharge water normally, and the damaged drip tape should be replaced in time to ensure the normal emergence of highdan grass and normal irrigation in the later period. Thinning should be carried out on highdan grass during the three-leaf stage, and one plant should be retained in each hole.

At the same time, it also improves the absorption and utilization efficiency of nutrients in the soil by sorghum, which helps to improve the yield and quality of sorghum.
