Jujube disease, also known as jujube tree broom disease, broom broom disease, is a highly contagious systemic infection of the whole body, is a devastating disease of the jujube tree, known as "jujube cancer." The victim's jujube tree will show its return to its ancestors, its branches and leaves. Diseased jujube saplings will die 1-2 times, and light trees will be dead for 5-6 years and 2-3 years for serious ones, causing great harm. Symptoms After jujube was infected with jujube, the aboveground part was mainly characterized by the degradation of floral organs, and the peduncle was significantly prolonged, which was 3-6 times that of normal flowers. The sepals, petals and stamens developed into leaflets, and the pistil developed into branchlets. A small number of small branches and leaves are sprouted in one year, the diseased branches are slender, the internodes are shortened, and the shoots are caused by the abnormal development and growth of the buds, resulting in the formation of "cluster branches." The leaves of diseased plants yellowed and became brittle, and the edges of the leaves curled to form a spoon, and they did not come off during the winter. On the diseased branch, the fruit is generally deformed, and the fruit surface is unevenly colored. The appearance of the fruit surface is uneven, the convex part is red, the depression part is green, the flesh is loose, and the food and economic value are lost. The underground part is mainly rooted in roots, and the roots that sprouted are also densely arbuscular. The later root bark rots and dies. In addition, in the autumn and winter seasons, the trunk buds in the dormant period of the tree trunk often germinate in large numbers, drawing small yellow-green twigs. The law of incidence 1. The incubation period of juvenile diarrhea pathogens ranges from 25 days to 1 year. 2. The occurrence of jujube disease usually consists of one or more branches first showing the symptoms of the disease, and then spread to spread throughout the tree. 3. The speed of spread of jujube disease varies with the time of infection, tree species, species, age, health status of the tree, soil, cultivation and management, graft pruning, and surrounding environment. First, the Zaoyuan with poor land and poor fertilizer and water conditions. Severe onset. The second is the management of extensive, overgrown jujube gardens. Third, jujube trees with a small age and weak vigor have a heavy incidence. Four is the spring infection, the disease symptoms can appear in the year; summer infection, generally the second year to show symptoms of infection. Fifth, trees that have been fleshed by livestock are susceptible to disease. way for spreading Jujube virus is divided into two types: long-distance transmission and close-range transmission. Bacteria usually spread long-distance through human processes such as transporting seedlings. In addition, some orchard farmers use diseased rootstocks or scions, diseased seedlings, etc., to trim and graft, as well as some sucking insects in the field, such as the edge of the diamondback leafhopper, the Chinese diamondback leafhopper, and the red leaflet leafhopper. Suck sucking trees, etc. for close communication.
