Method for cultivating pitaya

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a cultivation method of dragon fruit. Background technique [0002] pitaya( Hylocereus undatus ) for Cactaceae ( Cactaceae ) Measuring ruler belongs to ( Hylocereus undatus ) plant; its fruit is also called dragon fruit, which belongs to tropical and subtropical fruits, and is more and more popular because of its rich nutrition. [0003] Dragon fruit is drought-resistant, high-temperature resistant, light-loving, and has no strict requirements on soil quality. It can be planted on flat land, hillsides, and gravel land. The optimum soil pH value is 6-7.5, and it is not frost-tolerant. The optimum temperature for growth is 25- 35 ℃, low temperature higher than 5 ℃ can be planted in the open air, and the area with winter temperature below 0 ℃ can be planted in a simple greenhouse. It grows well in fertile, well-drained neutral or slightly acidic sandy...

Problems solved by technology

[0004] The cultivation mode of pitaya of prior art is the most common with column type cultivation, and column type cultivation is exactly to set up a cement column or wooden column, plant 3~4 strains of pitaya seedlings around the column, let the plant climb the cultivation that grows upwards on the column method, which has the advantages of low production cost and high land utilization rate, but because the climbing roots of the stem nodes need to climb on walls, fences, and cement columns, the extension ability of branches is limited, resulting in waste of space for clusters, and the utilization rate of water, fertilizer, and photosynthesis in the planting ground. Poor, and the excessive density of columnar cultivation branches leads to smaller fruit or increases the cost of flower thinning and fruit thinning, and excessive pruning will affect the yield
