Jujube natural root seedling seedling raising method

This is one of the methods commonly used for jujube propagation in jujube producing areas. Large jujube trees, especially some aging jujube trees, sprout some root seedlings every year. In areas where intercropping of dates and grains is intertwined, jujube roots in some shallow soil layers are often damaged when intercropped in fields, which increases the amount of root crops. Sometimes a few trees or even more than ten seedlings are often grown on a single wound. When growing seedlings, keep a strong one growing. Remove all the rest from the ground so that the nutrients are concentrated on the remaining seedlings. This seedling can grow to about 1m in that year. After the autumn or early spring, transplanting or nursery can be continued. When raising the seedlings, a mother root is required, and the masses call it the "Crooked Kidney Root." It is generally advisable to leave 15~20cm. If you do not remove excess seedlings in time. The growth of the seedlings will be very weak. Only one tree can be used in the future, and the rest must be cut off after emergence. Therefore, in the use of natural root seedlings, we must pay attention to timely seedlings, sparse excess seedlings, thereby improving the quality of seedlings.

The quality of jujube root seedlings is closely related to the site of emergence. The general condition is closer to the trunk of the mother tree, and the quality of the root seedlings planted on the rough roots of the mother tree is worse. Such root seedlings rely mainly on the nutritional life provided by the mother tree roots. Although the above-ground part grows vigorously, its rooting ability is weak, and its roots are underdeveloped or rootless. Therefore, the survival rate at the time of colonization is low, and the damage to the mother tree's root system is heavier when it is raised. However, the root seedlings that are farther away from the trunk of the mother tree are born with fine roots and have higher quality. This is due to insufficient nutrients supplied by the mother trees. Need to take root and absorb a nutrient. Although the upper part of this kind of root seedlings is not as strong as the former, there are many roots and the survival rate of transplanting is higher than that of the former, which is generally about 90%. In addition, root seedlings that grow on fine roots farther from the mother tree. Due to the slow growth, branches are more full, with more roots, and they grow faster after transplanting. The result is early. Therefore, when cultivating seedlings using the ramets method, the root seedlings farther away from the mother tree should be cultured as far as possible, and the root seedlings under the canopy should be removed as soon as possible.

Use this side to raise seedlings, easy to shape, low cost. However, there are also many shortcomings: First, there is a small amount of seedlings; the number of nursery stocks per year on a female tree is only a few to more than ten strains, and the number of seedlings per acre is within a few hundred strains; second, the seedlings are not neat, because The rooting seedlings mainly rely on the mother tree to provide nutrients. Because the roots have different strengths and weaknesses due to the different parts of the roots, the seedlings show size and thickness after seedling emergence. The third is that seedling roots are not numerous: due to the year of birth. The growth of root seedlings depends mainly on the mother tree, so the yielding roots are few and the roots are stunted. This kind of seedling has a low survival rate after transplanting, so it should bring 15~20cm long mother root when raising seedlings.
