The invention discloses a method for cultivating pitaya. The method comprises the following steps: a planting
ditch is dug; decayed farm
manure and soil are mixed at a
mass ratio of 1:2 is backfilled in the planting
ditch;
cement pillars are set up in the center of the planting
ditch and at an interval of 2 m, a position of 70 cm above the ground and a position of 140cm above the ground on each
cement pillar are perforated and penetrated by two cross beams, the cross beams are as long as 70 cm, and horizontal steel ropes are fixed between the cross beams between each two
cement pillars; and 4 pitaya stalks are
cut on furrow surface among the cement pillars, two left primary branches are drawn onto two steel ropes on the first layer through pull ropes, three left secondary branches are separately bound to steel ropes on the second layer, five
tertiary branches are kept, and the other new branches are
cut and removed. The method provided by the utility model has the advantages that
orchard space is fully utilized; the
absorption of water,
fertilizer and light by the whole
orchard is increased; the weight of a single fruit is improved; and after three years, the average yield can reach 1999.5 kg per mu, increasing by 44% over a conventional yield.
