Only emphasis on winter shear, but neglect summer shear jujube winter cut can adjust the tree vigor, improve the internal ventilation and light conditions of the crown, help to concentrate nutrients, improve the jujube fruit quality in the following year. "The winter cuts a long tree, and the summer cuts firm." The main measures for summer shearing are: except for sprouting, topping, pulling branches, removing dense branches, and backing up the branches. Some juvenile farmers do not attach importance to the summer cut, or the summer cut is not timely, resulting in a large number of jujube fall off, seriously affecting the output of the year.
Only pay attention to the management on the ground, but neglect the underground management Some jujube farmers do not apply fertilization or symbolic fertilization and watering to jujube trees for many years. In this way, despite the well-organized management of the above-ground parts, due to the lack of nutrients in the subsurface, the trees will also be extremely debilitated and the number of jujube fruits produced will be reduced and the quality will be deteriorating.
Only paying attention to chemical fertilizers, but neglecting organic fertilizers for long-term use of chemical fertilizers will lead to soil compaction, fruit sugar content is reduced, quality is reduced, and the original flavor is lost. The application of organic fertilizer can promote soil microbial activity, improve soil structure, increase the utilization of nutrients, and lay a good foundation for the production of pollution-free fruits.
Only pay attention to pre-harvest management, and ignore the management of post-harvest dates before the harvest, jujube farmers often manage the jujube, but after harvest, most of the jujube farmers abandoned the management of the jujube garden. This approach is inappropriate. Because the jujube harvested consumes a lot of nutrients, the tree is extremely weak, and at this time it is necessary to accumulate nutrients to prepare for the high yield in the following year.
Only pay attention to insecticide, do not pay attention to disease prevention Some jujube farmers believe that spraying the jujube tree, as long as the control of live insects on the line, this idea is not appropriate. Because the main diseases of jujube tree, such as date rust, shrinking fruit, are equally harmful to jujube, so management should pay equal attention to both insecticide and disease prevention.
