Key points of management of pomegranate trees in autumn and winter

In recent years, as pomegranate becomes more and more popular in the market, more and more people grow it, but the output has not gone up, which is mainly caused by improper management in autumn and winter. The ripening period of pomegranate in autumn is also the focus of pomegranate management, so should pomegranate trees be managed in autumn and winter? Let's take a look.

1. Fertilization

Autumn is not only the mature period of pomegranate, but also the period of falling temperature. Because the plant consumes a lot of nutrition after fruit production, the tree is weak and can not resist the cold wave, which will make the tree weaker and affect the fruit rate of the following year. It is also the reason why the yield has been low. Therefore, it is necessary to apply fertilizer immediately after fruit harvest in autumn, and it is also easy to re-apply, so that the tree potential can be recovered quickly. Fertilization is mainly organic fertilizer, combined with the amount of phosphorus and potassium fertilizer, the amount of fertilizer applied to young trees should be halved.

2. Shaping and pruning

After fruit picking, the plant has a large number of old branches, weak branches and diseased branches, these branches are a drag on the plant, will continue to consume plant nutrients, but it is not good for the plant, so it should be pruned in time to maintain the crown. Cut off all the old branches, weak branches and diseased branches to increase the plant permeability, which is conducive to the accumulation of plant nutrients and safe overwintering. When pruning, we should pay attention to the method, not long pruning, should be properly cut, each main branch fetus 2Mel 3 secondary main branches, pruning to protect the wound, so as to prevent the invasion of bacteria.

3. Qingyuan spray

In order to reduce the occurrence of diseases and insect pests in the coming year, the garden should be cleared thoroughly after pruning, collecting weeds and debris on the ground, falling branches and fallen leaves, and pruning branches together, and then burning them, and the ashes can be used as potash fertilizer. After clearing the garden, protective agents should be sprayed, which can not only prevent diseases and insect pests, but also reduce freezing injury and help plants survive the winter.

4. Cultivate the soil

In winter, the temperature is cold, and the root neck of pomegranate is easily frozen, so it is necessary to cultivate soil on the root neck before overwintering, so that it can survive the winter safely. The thickness of the soil is about 20-30cm. Soil cultivation should be moist and loose, and there should be a certain distance from the root system, so as not to damage the root system, or expose the root system, and cause the root system to freeze. It should be unearthed in time after the beginning of spring next year, so as not to sprout a large number of root tillers and affect plant growth.

5. Filling frozen water

Irrigation and sealing frozen water is also a common method for overwintering, which can help plants survive the winter safely and prevent spring drought. It can also reduce the insect source of wheat overwintering pests and eggs in the soil. Attention should be paid to the irrigation and sealing of frozen water, and it is appropriate to pour thoroughly at one time, and to loosen the soil and preserve soil moisture in time after irrigation, so as not to cause hardening caused by too much water in the soil, making it difficult for the roots to breathe and lead to overwintering failure.
