1, scaffold height, angle: When scaffolding, the first thing to pay attention to is to control the height of the scaffold. The vertical distance from the top of the bracket to the ground should be kept at about 180 cm, and then the angle should be controlled, because the vertical growth direction of the lower bracket will grow at a certain angle with the top bracket, and usually the large radius of the upper bracket is about 1/5 of the vertical height.

2. Scaffolding materials: mainly made of hard, pressure-resistant and corrosion-resistant reinforced concrete prefabricated parts. It is not suitable to use steel as scaffold material.

3. Stability of the support: the depth of buying soil at the bottom of the main column of the support should be determined according to the change of soil quality and surrounding environment. Usually, the shallowest branches should be kept at about 50cm, and then the drooping branches on the upper part should be evenly distributed.

4. Shelf density: Reasonable density is the basic guarantee for the growth and pruning of pitaya. In general, the plant spacing should be controlled at about 2 * 2.5m..
