一、推迟花期,避开晚霜天气。于秋季喷布50—100ppm的赤霉素,可使第二年春季花期推迟8—10天,或于春季化芽膨大期喷布500—2000ppm的赤霉素,可推迟花期4—6天,同时配合早春树干涂白、晚霜天气弥烟等综合措施。二、人工辅助授粉。将采集的花粉混合到白糖尿素溶液中,制成糖尿花粉液,用喷雾器喷布。糖尿花粉液的配方为水12.5千克,糖25克,尿素25克,硼酸25克,花粉25克。授粉宜在盛花期进行。
First, postpone the flowering, to avoid the night frost weather. Spraying 50-100ppm of gibberellic acid in the autumn can delay the second spring flowering period by 8-10 days or spraying 500-2000ppm gibberellin in the spring budding enlargement period, which can postpone flowering 4-6 days, At the same time with early spring trunk white coating, night cream weather and other comprehensive measures. Second, artificial pollination. The collected pollen was mixed with white sugar urea solution to make a solution of pollen, sprayed by a sprayer. Diabetic pollen solution formula 12.5 kg of water, sugar 25 grams, 25 grams of urea, boric acid 25 grams, 25 grams of pollen. Pollination should be carried out in full bloom.
