Method for increasing survival rate of bud-stock grafted oil tea seedlings and promoting growth of oil tea

The invention discloses a method for increasing the survival rate of bud-stock grafted oil tea seedlings and promoting the growth of oil tea, and relates to an oil tea growth promotion technology, in particular to an afforestation method for biennial bud-stock grafted oil tea seedlings. Root system branches of the biennial bud-stock grafted oil tea seedlings are pruned, and a leaf fertilizer is sprayed during the growth of the oil tea in the afforestation year, so that the afforestation survival rate and the growth are increased. The method comprises digging of big holes, uniform mixing of a base fertilizer, surface soil backfilling, selection of planting time, selection of strong seedlings, mixing of yellow mud, planting of trees, covering with grass, ditch cleaning and water removal, digging of bamboo joint ditches, soil loosening and weeding, and reasonable interplanting, and is characterized by further comprising the two procedures of pruning root system branches of the oil tea and applying the leaf fertilizer.
