Shaping and pruning of jujube
According to the unique branching habits and strong light-loving characteristics of jujube, the shaping and pruning of jujube trees can form a fixed skeleton suitable for jujube growth habits, improve the permeability of the crown, increase the position of fruit, and realize three-dimensional fruit. the purpose of improving the quality and yield of jujube fruit and prolonging the fruiting life.
There is no problem of flower retention: the flower buds of most fruit trees differentiate and form in the previous year, and the amount of flowers retained must be determined according to the determined yield during winter cutting, so as to reduce the occurrence of fruit trees consuming a lot of nutrients due to flowering and fruit setting. On the other hand, the flower buds of jujube trees blossom and bear fruit in the same year, and the flower quantity is very large and the flowering period is long. At the same time, it can differentiate flower buds and bear fruit many times. In the case of normal management, there is no phenomenon of annual results. Therefore, it is very convenient to trim, and there is no need to bother to save the amount of flowers. As long as the levels of branches at all levels are clear, the spacing between layers is investigated, the ventilation and light transmission are made, and the tree structure is reasonable.
The fruiting branch group is easy to culture and renew: several secondary branches growing on the main axis of the same jujube head form a fruiting unit, which is called fruiting branch group. Once the jujube head is picked from the heart or the terminal bud is cut off. It becomes a fruiting branch group. Small fruiting branches can have 5 secondary branches of 3mure. Large fruiting branch groups can be formed by coring jujube heads with uniaxial extension for many years or cutting off apical buds in winter. It can have more than 30 secondary branches. Results the branch group was stable after its formation. The growth is very small, but the ability of continuous fruit is very strong, which can bear fruit for more than ten years. When the fruiting branch group is old, it can be partially or completely removed, and the new jujube head can be used instead, so the renewal work is very simple.

The fruit is smooth, purple when ripe, bright in luster and medium in fresh quality. Mature in mid-September. The tree is medium-sized with strange posture and drooping branches on the outside. The crown of the tree is naturally semicircular. The 20-year-old tree is 6m in height and 6m in diameter. The grafted seedlings bear fruit in the second year after planting.

Prevention and control of peach gum disease
Peach gummy disease is a common physiological disease in peach trees, which mainly occurs in branches and has a great impact on the growth and development of peach trees. In addition to peaches, apricots, plums, plums, cherries and other stone fruit trees will also occur. Harmful symptoms: the disease can occur in any part of peach tree branches. The part of the disease is slightly swollen and the wood turns brown, then secretes a transparent glue from the lenticels or wounds, gradually turns yellowish brown to brown after contact with air, and finally becomes a black lump. The bark of the diseased part is rough, cracked, not easy to heal, and is easy to become a red neck sky.
