Method for promoting advancing of flowering of michelia maudiae 'Jinxiu' crossed seedlings

The invention discloses a method for promoting advancing of flowering of michelia maudiae 'Jinxiu' crossed seedlings, and belongs to a method of plant plantation. The method comprises the first step of artificially accelerating germination; the second step of growing seedlings in a greenhouse; the third step of conducting cultivation in a big field; the fourth step of conducting top grafting; the fifth step of supplying nutrients; the sixth step of conducting girdling; the seventh step of conducting hormone treatment. According to the method for promoting advancing of flowering of the michelia maudiae 'Jinxiu' crossed seedlings, the michelia maudiae 'Jinxiu' crossed seedlings can flower 2-3 years in advance, a new path is opened up for breeding of the new variety of the michelia maudiae, the breeding cycle is shortened, the breeding efficiency is improved, and meanwhile the cost in variety breeding is lowered. 本发明公开了种促进锦绣含笑杂交实生苗提早开花的方法，属于植物栽培方法，此方法包括以下步骤：(1)人工催芽(2)温室育苗；(3)大田栽培；(4)高接；(5)营养供给；(6)环剥；(7)激素处理。本发明可
