Jujube planting time

With the expansion of jujube market, the planting of jujube is rising day by day. However, planting fruit trees is not an easy task and requires a lot of professional skills and knowledge. So, what are the points for attention in the planting of jujube trees? When is the right time to plant? Now let's study together.

Jujube planting time

In fact, planting jujube trees in autumn has the best survival.

The planting period of jujube can be divided into autumn planting and spring planting. Autumn planting can be carried out from defoliation in autumn to before soil freezing.

The earlier the planting time in autumn, the better. If there is no need for long-distance transportation of seedlings, planting with leaves can be carried out in late September, which can improve the survival rate (the leaves of seedlings should be removed). Planting in spring next year can be planted late appropriately, if it is not planted in a large area, the survival rate is higher when jujube buds just sprout. From the theoretical analysis, the survival rate of jujube planted in autumn should be higher than that in spring next year, such as good soil moisture and low return to salt (saline-alkali soil), and the root activity is earlier than the aboveground part in the coming year, but the practical result is that the survival rate of late planting in spring is higher, the main reason is the loss of water of seedlings. Because it takes half a year for jujube trees to sprout from autumn to next year, the north is affected by cold and low temperature in winter, "air drying, loss of wind and other factors, resulting in the loss of water of seedlings.

In addition, jujube is a temperature-loving tree species, and the ground temperature needed for root activity and growth is higher than that of other northern deciduous tree species. In autumn, the soil temperature of jujube tree after defoliation is lower than that of root growth and activity, and the root system has no water absorption function. It is difficult to replenish the aboveground parts and cause the seedlings to die.

Advantages of planting jujube seedlings in autumn

The main results are as follows: 1. Jujube trees can be planted for a long time in autumn, from the festival in late October to the end of November, and it can make the planted jujube heal the root wound for a long time before the earth is frozen, so that it can grow well after spring.

2. The temperature is more suitable. Due to the gradual decline of air temperature in autumn, the water transpiration of jujube trees gradually weakened after planting, which was more beneficial to the survival of seedlings. And because the soil temperature drops more slowly than the air temperature, even if planted in late autumn, the physiological activities of the roots can still be carried out, and new roots grow in that year to restore vitality.

3. The quality of seedlings is acceptable. Autumn-planted jujube seedlings are all growing seedlings in the nursery, fresh and full of vitality, and spring-planted seedlings generally do not rise in advance due to the need of raising seedlings in the next crop. The sale of jujube seedlings can effectively avoid the decline of seedling vitality or even death caused by long-term poor storage.

4. Save labor and time. In autumn, watering times can be saved because of high soil moisture, good soil moisture, low temperature, small water evaporation and less water demand.

When will the jujube be transplanted?

Although it can be planted in both spring and autumn, it is mainly planted in spring because of the higher temperature required for the rooting and germination of jujube seedlings and the late germination of jujube seedlings. Under the same conditions, the survival rate can be as high as 90% after transplanting in spring budding period. In the northern region, from late February to early May (the temperature is above 18 ℃), because the sap has flowed, the jujube seedlings begin to grow, the injured roots are easy to recover and regenerate, and the underground nutrients can be transported to the aboveground parts in time, which is easy to survive. If planted prematurely in spring, jujube seedlings will lose too much water, and the root system will be difficult to supplement, which will affect the survival.

Matters needing attention in planting jujube in autumn

1. Key points for attention in seedling emergence

Try to avoid damage to the root system when raising seedlings. In order to facilitate planting, the main root can be slightly trimmed after seedling, so as to facilitate the seedling to absorb water and improve the survival rate. When the seedlings are transported, 50 to 100 trees should be tied up in a bundle, wrapped in plastic film and then transported.

2. Key points for digging holes

Dig a tree hole 50 to 60 centimeters square so that the root system of the seedlings can fully stretch in the pit. When digging a pit, separate the topsoil from the subsoil, and then fill the topsoil into the bottom of the pit.

3. Key points for attention in fertilization

Dig a good tree hole, apply 5 kg of high-quality organic fertilizer at the bottom, or add 20 kg of organic fertilizer to the bottom soil to fill the pit when planting seedlings.

4. pay attention to the main points of soaking roots

Before planting seedlings, soak the roots of the seedlings in phosphate fertilizer plus rooting powder solution for 20 minutes or dip in phosphate fertilizer solution and then plant them. The roots of the seedlings not only heal quickly, but also take root easily.

5. Key points to be noticed in planting seedlings

The saplings should be planted in the middle of the tree pit. When filling the soil, fill the fertile topsoil in the rhizosphere, cultivate the heart soil in the upper layer, and fill the soil layer by layer. The depth of the soil is 3-5 cm deeper than the original soil marks when the saplings grow in the nursery. When planting, shake the saplings while filling the soil, so that the roots can fully extend and connect closely with the soil.

6. Key points for watering

After the roots of the seedlings are fixed, they should be watered, and then the tree plates should be adjusted and cultivated into round piles to protect against wind and preserve soil moisture.

7. Key points for attention of film mulching

Covering the tree plate with plastic film on the planted jujube tree plate can preserve soil moisture, make the seedlings survive the winter safely, and the survival rate of jujube seedlings is high.

8. Key points for cold prevention

The skin of jujube seedlings is thin, the water content is low, and the water is easy to evaporate. Film mulching and wrapping can be used to prevent cold, and it can also bury the soil to prevent cold and improve the survival rate of jujube seedlings. First cultivate a 30 cm high soil platform at the base of the seedlings to fix the seedlings, and then cultivate 25 cm high soil in the direction where the seedlings are overwhelmed. After softening the seedling base, gently press the seedlings on the soil platform, and then cover the branches with wet fine soil 20 cm thick to prevent a "dead bend". Jujube trees begin to sprout only when the temperature reaches 13-15 ℃ in spring, so the time of removing cold-proof soil should be later, the exposure time of seedlings before germination should be shortened as much as possible, and the soil should be removed after the seedlings germinate.

After reading the above article, we know that jujube is divided into spring planting and autumn planting, and autumn planting is the best time, suitable for jujube planting. By following the correct planting method and planting jujube reasonably and scientifically, healthy jujube can be cultivated and greater benefits can be obtained.
