Winter jujube is familiar to us. Winter jujube is not only crispy and delicious, but also rich in sugar, and it is rich in various trace elements needed by the human body. In recent years, with the improvement of people's understanding of winter jujube seedlings, more and more people are planting winter jujube seedlings, but some farmers' management techniques are not in place. Planting winter jujube seedlings causes a large number of deaths. How to improve the survival rate of winter jujube seedlings? We all know that winter jujube seedling cultivation is a technically strong job. Correct understanding of planting techniques is the key to improving the survival rate of fruit trees.

     First, timely planting winter jujube seedlings deciduous fruit trees are strong in cold resistance, can be planted from autumn and winter leaves to spring before germination. However, production requires better planting after falling leaves in autumn and winter. Therefore, the soil temperature is also suitable for root growth to grow normally in the spring of the next year, and to increase the survival rate. For evergreen species such as citrus, it can be planted in the winter where the autumn fall is ripe after the winter is warm and freeze-free. In the cold and dry places in winter, it should be planted before the spring germination.

    Second, choose high-quality seedlings to choose robust, no pests, roots developed, high-quality seedlings without water loss. Evergreen seedlings require the leaves to be green and full of luster. If the planting plot is closer to the nursery, it should be transplanted with soil as much as possible, and the root system should be less damaged, shortening the time from seedling raising to planting. Long-distance transport attention to the moisturizing work of seedlings.

     Third, the treatment of winter seedlings before planting seedlings and planting methods Before planting, the seedlings are graded according to size, while the roots and dried roots are cut off, and the good roots are also cut off. Stimulate new roots with stimulation. Cut off weak and improperly positioned shoots. Then, the roots are mixed with a yellow mud slurry mixed with a sterilizing agent and a rooting agent, and planted immediately after rooting. When planting, hold the roots under the hand and straighten the roots into the planting pits so that the roots are evenly distributed around. If the roots are divided, they should be bottomed up and layered. When the soil is half filled, gently raise the seedlings to strengthen the plants, straighten the roots, and make the roots and soil better. Grafted seedlings can not exceed the marriage interface.

4. After the winter jujube seedlings are planted, the root water should be poured after the planting to maintain the soil moisture. Stand up to prevent survival due to wind and swing. After the seedlings grow 3-4 mature leaves, they are mainly applied with nitrogen fertilizer to promote the growth of seedlings.

     Fourth, cut dry. After transplanting winter jujube seedlings, the long roots with a diameter of 1 to 2 mm are short-cut, and the cuts are the same as the roots. The roots with a diameter of more than 3 mm are mainly used to treat the wounds at the roots, so that the wounds are reduced to a minimum. Promote new roots early and restore the tree as soon as possible.
