| description | The invention discloses a method for collecting high-quality Quercus parvifolius seeds, and belongs to the technical field of forest tree seed collection. The collection method comprises the following steps: selecting a 30-60-year-old seed tree which is seedling, robust, large and straight in trunk height, greater than 25 meters in tree height, 50-60 in ratio of tree height to diameter at breast height, 1/3 greater than the tree height under branches, perpendicular to the ground surface in bark seam, greater than 2.6 kg in thousand seed weight and thin in seed coat; tending the adjacent sunshade interference wood of the seed tree; ditching and fertilizing under the crown of the seed tree at the beginning of February; covering the vertical projection of the crown of the seed tree in the early April with organic matters, soil and a sunshade net; the scattered seeds are collected once every four days from October 1st to October 20th in the famous year.
