Embodiment 1
[0025] Dissolve 40 parts of NaOH in 1000 parts of water; dissolve 80 parts of anhydrous aluminum chloride in 1000 parts of water; drop the sodium hydroxide solution into the aluminum chloride solution, the initial drop rate is 200ml / min, and the stirring speed 1200 rpm, heated in a water bath at 65°C, when the amount of sodium hydroxide solution is close to 3 / 4 of the volume of aluminum chloride, the dropping speed is reduced to 75ml / min, and added dropwise until the pH value of the solution is 6.8, stop stirring, and stand for 24 hours. After the colloid is formed and stabilized, take the colloidal aluminum for use;
[0026] Take 1 part of colloidal aluminum and add 50 times the weight of water, stir at 1200 rpm, heat in a water bath at 60°C, and use it as a liquid inducer after the colloid is stable;
[0027] Spray the prepared liquid inducer on the American red grape vines in the young shoot growth period in the field, and spray 10 parts of the liquid inducer with 500 parts...
