The method of planting jujube cutting root and returning to nursery to raise seedlings

In order to cut off the root and return to the nursery to raise seedlings, we should first select the plant with good quality and free of diseases and insect pests as the mother plant. Before sprouting, a ditch with a width of 30 cm 40 cm and a depth of 40 cm was dug outside the crown of the mother plant to cut off the root system of the jujube tree, and the cut was cut flat with scissors and applied with organic fertilizer, about 75 kg per plant, mixed with wet soil, filled into the ditch and trampled, and if conditions were available, it was best to pour water once. Cover it with a layer of loose soil to preserve soil moisture. After the root of jujube tree is stimulated, a large number of tufted root tillering seedlings will be produced on the ground near the ditch from May to June. The management of root tillers and seedlings should be strengthened in time. After sprouting, too many buds should be removed, the principle is to keep thin, weak and strong, the general distance between plants is about 15 cm, in order to ensure the normal growth of seedlings.

The second step is to cut off the roots and return to the nursery. After falling leaves in autumn and before sprouting in spring. The sprouting seedlings near the crown of the mother plant were planed and graded, and the roots were soaked in 50 mg / kg indolebutyric acid or ABT rooting powder for 7 hours to promote rooting. The nursery was fertilized with sufficient base fertilizer and leveled out to make a border, with a width of 1 meter, 2 rows per border and a row spacing of 30 cm. When planting, the tufted root tiller seedlings should be cut and planted, and each seedling should have 3-5 hairy roots. Step on and irrigate after planting. Management should be strengthened in the growing season to promote the growth of seedlings. In the autumn of that year, jujube seedlings can come out of the nursery. It can also be postponed to the nursery next year as needed.
