Embodiment 1
[0033] Preparation of type I gibberellic acid product:
[0034] First dissolve 1.54% difenoconazole with 5% ethanol, then add the completely dissolved difenoconazole solution to 40% gibberellic acid mother liquor, then add 10% completely melted castor oil polyoxyethylene Ether, stir evenly, then make up with ethanol, and finally adjust the pH value to 2.0-4.0.
[0035] Type I gibberellic acid is used in seed production fields where the dosage of general-purpose gibberellic acid is 15 grams per mu, and the dosage of the product used is about 12 grams per mu.
Embodiment 2
[0037] Preparation of type Ⅱ gibberellic acid product:
[0038] First dissolve 0.69% difenoconazole with 3% ethanol, then add the completely dissolved difenoconazole solution to 40% gibberellic acid mother liquor, then add 10% completely melted castor oil polyoxyethylene Ether, stir evenly, then make up with ethanol, and finally adjust the pH value to 2.0-4.0.
[0039] Type II gibberellic acid is used for seed production fields where the dosage of general-purpose gibberellic acid is about 35 grams per mu, and the dosage of the product used is about 28 grams per mu.
Embodiment 3
[0041] Preparation of type Ⅲ gibberellic acid product
[0042] First dissolve 0.48% difenoconazole with 2% ethanol, then add the completely dissolved difenoconazole solution to 40% gibberellic acid mother liquor, and then add 10% completely melted castor oil polyoxyethylene Ether, stir evenly, then make up with ethanol, and finally adjust the pH value to 2.0-4.0.
[0043] Type III gibberellic acid is used for seed production fields where the dosage of general-purpose gibberellic acid is about 50 grams per mu, and the dosage of the product used is about 40 grams per mu.
[0044] Through the development and test of the product of the present invention in recent years, it has been found that in order to make the parents meet the ideal pollination requirements and obtain high-yield, high-quality F generation, attention must be paid to the variety combination, flowering period, development period, seedling growth, and weather conditions during use. And other factors.
