Examples
Embodiment 1
[0018] Embodiment 1 can improve the growth regulator and its application of hybrid rice seed production and sterile line seed propagation yield
[0019] The formula of the growth regulator in this example (content per 1 L): 0.1 mg of 2,4-epibrassinolide, 30 mg of 3-indole acetic acid, 0.5 mg of zeatin, pH value 5.8-6.5.
[0020] The preparation method of the growth regulator: weigh 2,4-epibrassinolide, 3-indole acetic acid and zeatin in proportion, first dissolve the above-mentioned components with a small amount of 95% alcohol, then dissolve them in water, and adjust the pH value 5.8~6.5, then set the volume to 1L.
[0021] The field planting method of hybrid rice seed production and multiplication (can be adjusted according to needs during actual application): the planting specification of the sterile line is 16.5cm × 20cm, single planting, the ratio of parent to parent is 2:10, and the operation In the aisle, 1500-2000 holes are planted for male parents and 13000-15000 hol...
Embodiment 2
[0036] Embodiment 2 can improve the growth regulator and its application of hybrid rice seed production and sterile line seed propagation yield
[0037] The formula of the growth regulator of this example (content per 1 L): 1 L of water contains 0.05 mg of 2,4-epibrassinolide, 30 mg of 3-indoleacetic acid, 1.0 mg of zeatin, and the pH value is 5.8-6.5.
[0038] The preparation method of the growth regulator: weigh 2,4-epibrassinolide, 3-indole acetic acid and zeatin in proportion, first dissolve the above-mentioned components with a small amount of 95% alcohol, then dissolve them in water, and adjust the pH value 5.8~6.5, then set the volume to 1L.
