What are the growth characteristics of jujube root system and the key points of jujube maintenance?

Jujube is one of the common fruits in China. Many farmers plant jujube trees. After the listing of jujube, the market demand is large and the benefits are good. Jujube is a fruit tree with strong adaptability to the environment. Its developed root system plays a very important role in the growth of jujube trees. What are the growth characteristics of jujube root system? How to maintain the root system of jujube?

Study on Growth Characteristics of Jujube Root System

1. The root system of jujube mainly develops in the horizontal direction. In other words, its roots are widely distributed, and most of its transverse roots are basically in the soil layer above 30 cm, so nearly 80% of the nutrients absorbed by its roots come from the transverse roots. At this time, red dates are the main source of nutrition.

2. The horizontal roots of jujube trees are widely distributed, and the vertical roots are also deep, reaching 3 meters, and some old roots can reach more than 5 meters. Therefore, although the vertical roots of jujube trees account for a small proportion of the total roots, they are very beneficial to the overall stress resistance of jujube trees and also play an important role in improving the soil utilization rate.

3. The root system of jujube is widely distributed, with deep roots and luxuriant leaves, but it takes time. In other words, once the root system of jujube tree is damaged, its recovery and regeneration are relatively slow, and the rooting of jujube tree needs high soil temperature. If the roots of young trees are destroyed, it is difficult to survive. If the seedlings grow slowly during planting, it is mainly because the root system is damaged.

4. The horizontal roots of jujube trees are easy to form tillering seedlings. Although tillering seedlings can be used for the propagation of jujube seedlings, excessive tillering will cause nutrient dispersion and affect the normal growth of trees, so attention should be paid to controlling tillering in cultivation.

Key points of jujube root protection

1, protect transverse roots and promote their growth. In view of the characteristics of well-developed horizontal roots and strong absorption function of jujube trees, measures such as deep turning and reaming were taken to induce the growth of horizontal roots as soon as possible, so as to drive the crown growth with the growth of horizontal roots. In the growing season, shallow hoeing or mulching measures should be taken in time to keep the topsoil loose and breathable and create a good root environment for the horizontal growth of roots.

2. In order to ensure that the soil has good air permeability, try to create good conditions for the growth of roots, and try to choose soil with good air permeability and deep soil layer. If the local soil viscosity is high, it needs to be improved, such as applying organic fertilizer, deep ploughing, expanding the thickness of active soil layer and promoting the vertical growth of roots, so as to improve the drought resistance.

3. When planting, ensure the integrity and vitality of the root system and promote the formation of new roots. Because jujube trees are difficult to take root, pillows should be placed when transplanting to avoid low survival rate of jujube trees.

4, to do a good job of transplanting and utilization of tillers. In view of the characteristics that jujube trees are easy to form tillers, tillers can be removed in autumn and winter, and tillers should be removed in time during the growing season.

5. Fertilizer should be used reasonably. Efforts should be made to improve the utilization rate of fertilizers, rationally use organic fertilizers and chemical fertilizers, and use quick-acting fertilizers and slow-release fertilizers. Usually, we should pay attention to the fertilization method, and the fertilization position should not be too close to the trunk of jujube trees, because the nearby roots are relatively developed, which is easy to cause root damage. We can dig ditches and fertilize outside the vertical projection of the crown, which will not damage the root system of jujube trees and improve the utilization efficiency of fertilizer.

6. We should pay attention to the water supply of jujube trees. Although the overall drought resistance of jujube trees is good, we should be careful not to let them lack water. Otherwise, although it will not have much impact on jujube trees, the quantity and quality of fruits will be poor after all, so it is necessary to ensure that jujube trees have enough water. Don't smear too much, at least don't affect the air permeability of the soil because of too much soil moisture, which will have a very adverse effect on the root system of jujube trees.

The above are the growth characteristics and maintenance points of jujube root system. If you want to grow well, you must pay attention to the growth of jujube root system. Only when the roots of jujube trees grow well can jujube trees grow well and get a good harvest. Growers should pay attention to the above points and take good care of the root system of jujube trees.
