The planting time of jujube trees is related to efficiency, when is the best time for jujube trees?

Generally, jujube trees are split and cut from late March to mid-April, subcutaneous and ventral grafting when the rootstock cortex is easy to peel off from mid-May to late August, and square-shaped or "D" shaped budding can be carried out from early May to July. 5 Grafted in June, germinated in that year. Grafting Method:

Bonding (skin jointing), folding jointing, and splitting techniques can be used (bud jointing is carried out in the eighth month of the lunar calendar). The following is a brief discussion of bonding methods. The tree body is removed in parallel with a saw or shears, the stubble is flattened with a sharp knife, and then a vertical knife is cut, and the cortex on both sides is separated by a bud scion for use, and the jujube scion can be collected in winter or spring, and the annual development branches are selected, requiring uniform internodes, full growth, and full bud eyes.

If you pick up crops in a short period of time after collection, you can store them in wet sand, and if you store them for a long time, you have to store them in a wax sealed bag in the shade.

The so-called jujube tree grafting is to transfer the branches of a good variety to another jujube tree, so that this branch can survive, bloom and bear fruit on another jujube tree. This is one of the most common methods of jujube tree propagation. It has the characteristics of convenience, fast and quick effect.

The varieties of jujube trees are relatively rich, and the climatic conditions in various places are also different, so the time of grafting jujube trees is also different. However, although there are many varieties of jujube trees, their fruiting period is basically concentrated in early summer, that is, in May and June every year.

Jujube trees can be grafted from March to August, but grafting from mid-April to early May not only has the highest survival rate, but also can grow new branches in that year. Although jujube trees are very common in life, the survival rate of grafting is the highest time period for other fruit tree varieties, and the survival rate can be as high as more than 90%. Of course, it can also be grafted during the Qingming Dynasty or when it is small, but at this time, the grafting scion treatment is relatively troublesome, and the scion must be collected and used immediately.

Dig out the soil about 10 cm deep downward, expose the smooth part of the rhizome, cut the rootstock cross-section with scissors, and split the rootstock longitudinally along the center of the rootstock cross-section with a longitudinal incision of 2-3 cm.

The best time to plant is in the spring, preferably in April, to increase yields and ensure the right conditions for planting.

The best time to plant jujube trees is from late October to late November, and the survival rate of jujube trees is quite high.

The best time to plant jujube trees should be planted with leaves in late September, and the survival rate will be relatively high.

Jujube trees are best planted in autumn and spring.

The planting period of jujube trees is divided into two types: autumn planting and spring planting. In some areas, when planting jujube trees in autumn, the survival rate of autumn jujube seedlings has been significantly improved by taking measures such as watering after planting, watering frozen water and watering germination water in the spring of the following year. However, most of the north still uses the spring planting method.

During this period of planting, there are few lost buds and back buds, and the growth potential is also strong.

How to plant jujube trees

1. A bag of soil planting method

Instant plastic bag: such as laundry detergent bags, food bags, etc., filled with water-filled fertile soil or clay, pierce 2-3 small holes at the bottom of the bag, put the plastic bag filled with soil vertically in the middle or side of the planting hole that has been dug up, and then put the seedling taproot or 2-3 side roots into the bag, and the rest of the root system is naturally stretched, and the soil is quickly cultivated and solid, so that the root system is closely connected with the soil.

A bottle of hydroponics

That is, the use of old canned bottles and wine bottles, fill the bottle with water, put it on the side of the planting hole, the bottle mouth is slightly inclined to the center, insert 1-2 lateral roots of the seedlings into the bottle, and the rest of the roots are naturally stretched, and the soil can be firmly cultivated. However, it should be noted that the root system in the bottle can not be put more, because the root system in the bottle can only temporarily absorb water and promote the germination of seedlings.

Cultivation method of large radish

That is, taking advantage of the characteristics of high water content of large radish, put the large radish into the lower part of the planting hole, 1-2 per hole, and then put the seedling taproot on the large radish, so that the root system can be naturally stretched around, and the soil can be cultivated.

The survival rate of planting jujube trees in autumn is the best.

Advantages of autumn planting jujube saplings:

1. The autumn planting time of jujube trees is long, from the festival in late October to the end of November, and the planted jujube trees can heal the root wounds for a long time before the earth freezes, so that they have good growth after spring.

2. The temperature is more suitable. In autumn, due to the gradual decrease in temperature, the transpiration of jujube trees gradually weakened after planting, which was more conducive to the survival of seedlings. In addition, because the ground temperature drops more slowly than the air temperature, even if planted in late autumn, the physiological activities of the root system can still continue, and new roots will grow in the same year to restore their vitality.

3. The quality of seedlings is acceptable. Autumn planting jujube seedlings are seedlings growing in the nursery, fresh and full of vitality, generally will not appear spring seedlings due to the need for stubble seedlings and seedlings in advance of false planting or seedlings for sale after the seedling, ** jujube seedlings effectively avoid the situation that the seedlings become less vigorous or even die due to long-term poor storage.

The survival rate of transplanting jujube trees about 10 days before germination in spring (late March in Lunan area) is relatively high, and the survival rate of transplanting jujube trees about a week after leaf fall in autumn is also very high.

The planting time of jujube trees is generally more in spring and autumn, and it varies from region to region, mainly as long as the survival rate is high, and when the recovery time is good. Generally in the south, the winter temperature is relatively mild, and the wound can heal after transplanting in autumn and grow new roots, which does not affect the growth of the next year, so it is planted more in autumn. In the north, winter is not conducive to growth, and choose to transplant in spring, after planting and timely watering, especially transplanting about ten days before the word germination, the survival rate is the highest.

Now, regardless of the north and south, transplanting jujube trees will use happy forest rooting powder, even if the transplanting time is a few days different from the optimal time, the survival rate is relatively high.

Jujube trees generally bud in early April, considering that it takes 20 days for jujube trees to survive and bud after planting, the best time for jujube tree planting is early March, and in this case, the temperature is not too high, and the water evaporation of jujube trees is relatively slow, thereby improving the survival rate.

Planting technology: put the rooting agent into the vessel according to the ratio of 1:600 dilution, and then put the jujube tree into the vessel to soak for 8 hours, pay attention to the soaking solution should not pass the tree stem, and the soaking time should not exceed 10 hours.

The pit pore diameter of the planting tree is much larger than the aperture of the rhizome of the jujube tree by 10 cm, and the deep depth is more than one-third of the length of the rhizome of the jujube tree, and the pit size exceeds the rhizome of the jujube tree, which is beneficial to the flexion and extension of the rhizome during planting.

Mix with 250 grams of organic fertilizer and 1000 grams of high-quality soil, and sprinkle the mixed fertilizer evenly at the bottom of the pit and around it, paying attention to the fertilizer to mix well. When planting, the soil does not have to pass the grafting position of the jujube tree to avoid the death of the jujube tree caused by bacterial and viral infection in the soil layer. Cut off the branches and branches at the first branch of the jujube tree, and tie the cut tightly with film to prevent the cut from being blown dry by the wind.

The jujube tree should be watered twice on the first day of planting, each time it should be watered, and after 10 days of continuous watering, it should be covered with agricultural mulch.

Nursery land selection and ploughing. The seedling base should be selected from the sandy loam land with flat terrain, convenient irrigation and rich soil layer, and the nursery land can not be cropped. After applying the plantar fertilizer, subsoiling is carried out, and the water injection and drainage pipes are repaired according to the water resources.

Drought-stricken areas should be planted in low beds, and places with a lot of precipitation should be planted in raised beds.

Seedling selection. Root tiller seedlings should be strictly selected without madness, budworms and other pests and diseases of green seedlings to return to the nursery. It is better to have a root tiller seedling with a thick stem diameter (too thin or too thick green seedlings have a low germination rate and a weak growth rate after returning to the nursery).

After rigorous selection, the root tillers and seedlings are pruned, and the branches, stems or longer roots are cut off, and each plant is preserved with 1 new shoot about 35 cm long, and the others are trimmed. Then the seedlings are classified according to the size level of the seedlings, and the seedlings are planted first.

Transplant seedlings. After the ground is straightened, dig a vertical long ditch, the length of the ditch can be determined according to the nursery land, the width of the ditch is 30 cm, the depth of the ditch is 20cm, and the distance between the ditch and the ditch is 60-70cm. The root tiller seedlings of the seedlings are removed and planted in the ditch, the plant spacing is about 30 cm, and 3000-4000 plants are planted in 1 acre.

Because the jujube tree has secondary branches, the angle of branches is large, and the growth and development of root tillers and seedlings are fast, the relative density is not too large, more than 4000 plants, the development is not good, the branches are closed, and it is easy to suffer from pests and diseases such as jujube rust. After transplanting the seedlings, cover the soil, stabilize and inject water.

Greening seedling management methods. After the planting of green seedlings, wipe the buds, cut off a part of the ground at 2-3 cm from the ground, select a seedling to grow and develop a strong bud after the bottom bud germinates, erase the other buds, and then carry out weeding, fertilization, prevention and control of pests and diseases in accordance with the basic method of pre-seedling. Generally, after 1 year in the nursery, when the seedlings are 1 meter tall and have grown and developed a lot of new roots, they can be planted in the nursery.

The best time to plant jujube seedlings can be in autumn or spring, as long as there is no too cold area can be planted, and then choose some stout, and no madness and insect disease saplings.

The best time to do this is around May; Seedlings with better cold resistance, stuber saplings, and saplings with higher survival rate should be selected to improve yield.

It is best to plant date trees in mid-April every year. When choosing a sapling, you must choose a regular farm, you should see whether there is soil at the bottom of the sapling, and whether the roots of the sapling are particularly vigorous.

<>1. The survival rate of jujube trees planted in spring is generally higher.

2. The time of planting jujube trees is generally mainly in spring and autumn, but due to the high temperature required for jujube seedlings to take root and germinate, and the late germination of jujube seedlings, autumn planting is not advocated in actual production, but spring planting is the mainstay. Under the same conditions, the survival rate of transplanting jujube trees in the spring budding period can be as high as about 90%.

Mastering the best time and planting method when planting jujube trees can not only improve the survival rate of jujube trees, but also make jujube trees grow gratifyingly, so as to achieve high quality and high yields.

1. Planting time

Jujube tree germination is generally in early April, considering that it takes 20 days of growth period after jujube tree planting to survive and germinate, so the best time for jujube tree planting is early March, and the temperature is not high at this time, and the water volatilization of jujube tree is slow, so as to improve the survival rate.

2. Planting method

1.Put the rooting powder into a container and dilute it at a ratio of 1:600, and then put the jujube tree into the container and soak it for 8 hours, noting that the dilution should not exceed the roots when soaking, and the soaking time should not exceed 10 hours.

2.The diameter of the pit should be 10 cm larger than the diameter of the root system of the jujube tree, and the depth should be greater than one-third of the length of the root system of the jujube tree.

3.Mix well with 250 grams of organic fertilizer and 1000 grams of high-quality soil in the sedan car, and evenly sprinkle the mixed fertilizer at the bottom and around the pit.

4.When planting, the soil should not be covered by the grafting part of the jujube tree to prevent the death of the jujube tree caused by soil bacterial infection.

5.Cut off the main branch and side branches at the first branch of the jujube tree, and wrap the cut tightly with plastic film to prevent the cut from being blown dry by the wind.

6.The jujube tree should be watered twice on the first day of planting, and each time it should be watered thoroughly, and after 10 days of continuous watering, it should be covered with mulch.

<>1. The planting period of jujube trees is divided into two types: autumn planting and spring planting. Wherever there is no severe cold in winter and the average temperature in January is not less than -8, autumn planting can be carried out, that is, after the jujube trees have fallen their leaves and before the soil freezes.

2. In the jujube area south of the Yangtze River in China, the winter is relatively warm, the soil moisture is good, and the wounds of the root system of the jujube tree can be healed in the year of planting, and some new roots occur. It can grow in time for the next spring. Therefore, the survival rate of jujube trees in autumn planting is high and grows well.
