How many years does black jujube plant bear fruit?

Black jujube generally refers to the deciduous persimmon tree Jun Qianzi, also known as soft jujube, milk jujube, wild persimmon, clove jujube, jujube, small persimmon and so on. How many years does the black jujube tree bear fruit?

First, how many years of black jujube trees have been planted?

Grafted black jujube trees usually take 3-4 years to bear fruit, but ordinary seedlings take more than 5 years to bear fruit. The flowering period is from April to May and the fruiting period is from August to September.

Second, how to plant black jujube trees?

1. Land selection and preparation

Black jujube likes fertile and deep soil, is resistant to barren, has a certain saline-alkali tolerance, and can grow normally in mild saline-alkali soil with pH 8.7 and salt content 0.17%. Land preparation generally requires full reclamation, but if there are crops in the previous crop, hole reclamation can be considered. Soil preparation should be carried out in combination with fertilization, and base fertilizer should be fully applied.

two。 Timely planting

Generally, it can be propagated by grafting. The planting density is controlled at row spacing of 2 meters and plant spacing of about 1.5 meters. Black jujube can be planted in spring and late autumn after defoliation, because its germination is relatively late, so it can be planted late, but it must be planted before sprouting, and the survival rate is not high if planted after sprouting.

3. Water and fertilizer management

When planting, we should use some rotten and fermented cow and horse manure as the base fertilizer, mix the base fertilizer well with the planting soil, pay attention to layer-by-layer and firm soil when backfilling the soil, and then pour water in time, two water after 5 days, and three water after 10 days or so. In the subsequent management, the soil moisture can be watered according to the soil moisture, and the general principle is to keep most of the soil moisture. Loosen the soil in time after each watering. The stagnant water should be removed in time on rainy days in summer. Pour enough anti-freezing water at the end of autumn. Defrost water was poured in time in early spring of the following year, and nitrogen fertilizer was applied once in the sprouting period. If the plant did not grow well, 0.5% urea solution could be sprayed on the page in May, once every 10 days, and continuous spraying for 2 to 3 times could be effective. Phosphate and potassium fertilizer was applied once in July and frozen water was poured at the end of autumn. In the third year, the method of watering and fertilization was carried out according to the method of the second year. From the fourth year, farm manure should be applied once a year at the end of autumn, thawing water should be poured thoroughly, and reliable natural precipitation should be grown at other times. If it is not particularly dry, there is no need to water alone.

4. Timely pruning

The trunk should be fixed in accordance with the requirements of use in the seedling stage (the trunk height is generally 2.8 m to 3 m). There should be 3 to 4 main branches in the crown, and the main branches should be evenly distributed, each occupying one side. Four to five side branches can be left on each main branch, and sufficient space should be left when the side branches are selected, and the subordinate relationship of the whole tree should be paid attention to to make it grow evenly. After the formation of the basic tree shape, competitive branches, overlapping branches, over-dense branches, cross branches, disease and insect branches should be thinned in time.

5. Pest control

Attention should be paid to the invasion of diseases and insect pests such as anthracnose, round spot, shell insects, diamondback moths and persimmon caterpillars, spraying chemical control in advance, and at the same time doing a good job in clearing the garden and pruning diseased branches and leaves.

Black jujube can bear fruit after planting for three or five years. In addition to its edible fruit, it can also be planted as a courtyard tree and a green tree.
