Pecan low altitude large area harvesting method

The invention discloses a pecan low altitude large area harvesting method, which is characterized in that at the mature period of the pecan, according to the irregular intervals of the pecan, selecting a high weather-proof plastic chaining harvesting net (1), at 3-5 meters above a fruit-bearing forest, flatting and fixing the harvesting net in mid air below a fruit tree by using a pile (2) whose of which height is 2-2.5 meters, and extending downwards; passing the harvesting net through the fruit tree at a near opening (3) according to each irregular fruit tree and fixing the harvesting net at about 2 meters of the tree stem with a hook (4); connecting the nets with through a buckle (5); fixing and supporting two sides with a pile higher than 2.5 meters, thereby therefore the large area harvesting net is formed below the pecan tree at low altitude; according to the slope of the pecan forest, a plurality of collecting openings (6) are opened formed at the bottom of the net at the relatively lower slope and a c
