Pomegranate planting density

The planting density of pomegranate is related to variety, tree shape and site conditions, generally, the plant row spacing is controlled at about 2 × 3m-3 × 4m in the mountain slope with poor soil and lack of water, and the plant row spacing is controlled at about 3 × 3m-3 × 4m in the plain with fertile soil and sufficient water resources, the plant row spacing of varieties with luxuriant branches and leaves should be sparse, and the plant row spacing of varieties with upright branches can be slightly denser, and the specific density can be adjusted according to the actual situation.

The planting density of pomegranate is adjusted according to their varieties, tree shape and site conditions. if pomegranate is planted on mountain slopes with poor soil, shallow soil layer and poor irrigation conditions, the plant-row spacing can be controlled at 2-3m × 3-4m. If planted in plain areas with fertile soil, thick soil layer and rich water resources, the plant-row spacing can be about 3 × 3m-3 × 4m.

For example, the row spacing of Taishan Dahong pomegranate with luxuriant branches and scattered branches is 3 × 4m, while that of Lintong Dahong sweet pomegranate is 2-3m × 3-4m. The density of single trunk shaping can be controlled at about 2 × 3m, and the shaping density of 2-3 trunk is best controlled at about 3 × 4m.

Common diseases and insect pests in planting pomegranate and their control

1. Pomegranate stem window moth

This pest is mainly harmful to pomegranate branches, and the general control methods are as follows:

At the beginning of July every year, it is necessary to check and know that if a branch or treetop is injured by pests, it should be cut off immediately and the larvae inside should be killed; after the pomegranate tree begins to sprout in spring, all dead branches without leaves on the tree should be cut off and burned, killing the overwintering larvae in it.

In general, the pest larvae in 2-3-year-old branches can be injected with 500 times dichlorvos solution or 800 times dichlorvos solution or 800 times dichlorvos, and then plug the insect mouth with medicine mud to kill the larvae.

The newly hatched larvae can not be eaten into the branches until 2-3 days later, so during the peak period of pest incubation, 1500 times of 40% omethoate, 50% methamidophos or 40% monocrotophos are sprayed to control the larvae into the treetops, and the general control effect can reach 84.9-98.4%.

In addition to the above methods, the seedlings can also be sprayed directly, and the effect will be better than that injected from the insect mouth, and it can also control the harm to the seedlings caused by other leaf-eating pests such as the yellow diamondback moth to a certain extent, generally after the first spraying, spray the second time in about 20 days, it will have a better effect.

2. Peach borer

This kind of pest is mainly harmful to pomegranate fruit, and the damage rate to pomegranate fruit can even reach 50-70% when it is serious. In the process of planting, it can be controlled by favorite methods:

Check and clean the orchard in winter and kill the overwintering larvae; scrape off the cracked bark in time before the trees begin to sprout in early spring, remove the insect fruits from the trees or pick up the fallen fruits eaten by pests and burn them; use sugar and vinegar or sex information hormones to confuse male adults and then kill them At the initial stage of hatching of the first generation of larvae, 50% fenitrothion EC, 40% omethoate EC or 50% dichlorvos EC 1000 times can be sprayed to prevent it.
