The latest course of planting techniques and methods of black jujube

Black jujube is also called wild persimmon, clove jujube, there is a kind of black jujube is nuclear, and there is a kind of artificial grafting variety is seedless. Its main varieties are large stone black jujube, milk jujube, grape black jujube these three kinds. Black jujube it has qi, spleen, stomach and other functions, medicinal value and high edible value. Now black jujube is mainly planted in Hebei, Shandong, Shanxi and other places in our country, so today we will follow them to learn the planting technology of black jujube.

1. Selection of the garden

Black jujube has the characteristics of light, fertilizer, shade tolerance, salt tolerance, cold tolerance, drought resistance, moisture tolerance and strong adaptability, that is to say, black jujube has very strong resistance. Generally, we will choose to plant black dates in semi-yin and semi-yang, fertile soil, moderate pH, sufficient water, and no pollution. If it is wasteland, the land preparation generally needs to be fully cultivated, but if it is a crop before the crop, you can consider hole cultivation. Soil preparation should be combined with fertilization, and base fertilizer should be applied sufficiently, which can not only improve the structure of soil in planting land.

2. Seed treatment

Black dates are propagated by seeds in the traditional planting process, but now large-scale planting is generally carried out by grafting. When using seed propagation, we need to treat the seeds. First, we need to clean up the residual flesh or impurities on the seeds, then select plump and healthy seeds, mix them evenly in wet sand, and finally store them with wet sand.

3. Sowing method

Black date planting is generally carried out in the spring of each year, of course, it can also be planted in the winter of each year from November to December. Sowing is generally not carried out by direct seeding. The seeds are evenly scattered in the field, then covered with soil and watered again. If the temperature is low, you need to cover a layer of straw or film above to keep warm and moist. Of course, hole sowing can also be used, and hole sowing needs to be carried out according to the density required for black jujube planting.

4. Seedling management

Before the black jujube has not emerged, we must maintain a certain humidity in the field. Before the emergence, the humidity in the field should be kept at about 50%. The humidity should not be too large, otherwise it will easily cause rotten seeds and affect the emergence rate of black jujube. However, if it is winter sowing, we need to irrigate the soil thoroughly after sowing, and wait for emergence after covering straw and film. After emergence, we have to wait at least seven days before watering, so that it can adapt to the environment as soon as possible, and appropriate topdressing to promote the growth of seedlings.

5. Field management

When the black jujube seedlings grow about 20 cm, we can transplant the seedlings and transplant them. The planting density is controlled at a row spacing of two meters and a plant spacing of about 1.5 meters. After planting, when the sapling grows to about fifty centimeters, the sapling should be properly pruned. In short, during its young tree period, it should be pruned at least six times a year until it forms a complete tree shape. After the black jujube blooms, it needs to be watered and fertilized reasonably according to its different growth periods, and the branches and leaves are pruned and the garden is cleaned every spring and after fruit picking.

The above is the planting technology of black dates that Xiaobian wants to introduce to you today. I hope it can help you. If you want to know more about planting techniques, remember to pay attention to us.
