The latest course of field management techniques and methods of winter jujube

Winter jujube is a very high quality jujube cultivar with smooth surface, rich nutritional value and high sugar content. Winter jujube has not only all the nutrients of other jujubes, but also more than a dozen essential amino acids for the human body. So now more and more people grow winter jujube, so when we plant winter jujube, how to manage it? The following editor brings you the field management technology of winter jujube, let's have a look!

1. Shaping and pruning

When we plant winter jujube, we must do a good job in shaping and pruning. We should choose the shaping method reasonably according to the planting density, and the free spindle shape should be given priority to in the high density jujube orchard. It is necessary to maintain a uniform distribution of about 9 main branches on the trunk, and there should be no stratification and overlap. The length of the main branch is controlled at about one meter, the length and lower part of the main branch is short, and about 6 branch groups are retained. Each branch group should not crowd each other, cross and other bad phenomena. It is necessary to remove some useless branches in time to improve the permeability of the crown. The jujube was selected from the base of the jujube tree for branch group renewal.

2. Fertilizer and water management

If the orchard is closely planted, then the soil of the orchard should be kept soft enough to ensure that there are no weeds and have good drainage and irrigation measures. When topdressing jujube, it is necessary to give priority to rhizosphere and extra-root topdressing. Topdressing in the rhizosphere should be carried out before sprouting, before flowering and fruit stage, and fruit expansion and other important growth stages. According to the different growth period, the proportion of nutrition in fertilizer should be controlled to meet the nutritional needs of winter jujube. Then in these periods, we should also pay attention to watering to prevent soil drought from affecting the growth of winter jujube. However, the moisture and humidity in the field should not be too large, and it should be drained in time, otherwise it is easy to produce bad phenomena such as fruit cracking and fruit drop.

3. Flower and fruit management

After the winter jujube tree blossoms, when it is found that there are about 5 new jujube crutches on the jujube head, the heart-picking work should be carried out according to the growth of the jujube head. The strong and weak dates are retained in the proportion of 4:3. Then after sprouting in winter, the excess jujube on the branch group should be erased in time to avoid consuming too much nutrition, in order to enhance the growth of winter jujube and increase its yield. After entering the budding stage of winter jujube, remove all the lateral flowers and keep about two central flowers. The concentration of nutrition on the fruit can not only promote the fruit expansion, but also effectively improve the fruit setting rate.

4. Timely harvest

When we harvest winter jujube, it can not be carried out after the winter jujube is fully mature, its storage and transportation capacity is very poor, it is very perishable and loses its commodity value. Therefore, we should harvest when the fruit is colored by about 25%. The storage and transportation capacity of fruits at this time is relatively high. When picking fruit, if the method is to beat down, then the bottom should put cloth strips and other buffers, to avoid fruit injury, affecting the yield.

The above is a brief introduction to the field management technology of winter jujube. The field management of winter jujube is very important, which directly affects the yield and fruit quality of winter jujube, so we must pay more attention to it when planting. That's all for today's introduction. This article is for reference only. I hope it can help you all.
