Method for shortening the production period of mango

The invention relates to the plant hybridization breeding and cultivation technology and provides a method for shortening the production period of mango. The method is characterized by comprising the following steps: 1) sowing seedlings and transplanting; 2) selecting polyembryonic varieties to be grafted trees, performing heading-back cut to grafted trees half treetop to use as stock; 3) selecting robust seedlings for grafting, top-grafting the seedlings on the stock of grafted trees; and 4) dressing multi-effect triazole in the soil, digging shallow ridges on the two sides of the tree covers of the grafted trees after grafting, irrigating multi-effect triazole and earthing. The invention has the following prominent substantive features and significant progresses: 1. seedling high grafting technology is adopted in the method so as to increase the grafting survival ratio; 2. the dressing multi-effect triazole technology is used to control the spindling of branch tips of grafts, promote the branch tips for agi
