Basic Information
Scope
Main Technical Content: 4.1 Pest and Disease Control The prevention and control of pests and diseases in winter jujube cultivation is one of the main aspects of production management. From the budding, leaf unfolding, flowering, fruiting, to fruit ripening stages of winter jujube trees, various pests and diseases pose threats. The severity and types of pests and diseases are greatly influenced by climate and seasons. In dry years, pest damage is more severe, especially for sucking insects, which can cause outbreaks when environmental conditions are favorable. In years with heavy rainfall, diseases become serious, affecting not only flowering and fruit set, but also fruit quality and yield, and in severe cases, leading to complete crop failure. 4.2 Control Methods Zhinhua winter jujube pest and disease control adopts the principle of "prevention-oriented, integrated management", combining plant quarantine, forestry measures, biological control, physical control, manual control, and chemical control. Control methods shift from in-season prevention to dormant-period control, with on-tree control focusing on underground prevention. The aim is to detect and treat pests early, prevent damage before it becomes serious, and avoid pests and diseases causing harm. 4.3 Plant Quarantine Control Plant quarantine is a regulatory measure aimed at preventing the spread of dangerous diseases, pests, and weeds. It includes international and domestic quarantine, where goods are inspected during transportation to prevent the introduction of dangerous pests and weeds. Quarantine is the foundation of integrated pest and disease control. To prevent Zhinhua winter jujube from being infected by new pests and diseases, all forestry seeds, seedlings, and by-products entering the production area must pass quarantine inspection before use. Externally sourced Zhinhua winter jujube seedlings, grafting buds, and fruits must also undergo quarantine inspection and obtain plant quaranti
