How does the harm of Lycium barbarum rust mite come about? How to prevent it?

It mainly harms leaves, tender stems and fruits. In the disaster-stricken areas, densely planted yellow clover appears small spots, insect-like deformity or distortion, which seriously hinders plant growth, leaves and tender stems are not cooled, and fruit yield and quality decline. Lycium barbarum is a plant of Lycium genus in Solanaceae. Commercial Lycium barbarum, Lycium barbarum planted in Ningxia, Lycium barbarum in China, etc. , an important agricultural product and one of the main export agricultural products in China, is widely planted in northwest China. Lycium barbarum is not only drought-resistant but also salt-tolerant, so it is usually planted on sandy land and alkaline soil, which makes great contributions to soil and water conservation, wind and sand fixation and improvement of ecological environment. But now people don't know much about the integrated control of diseases and insect pests in Lycium barbarum, which has a great influence on the yield and quality of Lycium barbarum.

Lycium barbarum growers should form the concept of focusing on treatment. You can't just know that pesticides are sprayed as soon as pests and diseases occur. Lycium barbarum growers should plant varieties that are more resistant to pests and diseases, and then solve the problems of pests and diseases and reduce losses through scientific and reasonable planting techniques combined with certain physical and biological control methods. Many different diseases and insect pests may occur during the growth of Lycium barbarum, including about 5 main diseases and 38 pests. Among them, 3 diseases and 6 pests are high-risk pests, especially Lycium barbarum black fruit disease, Lycium barbarum flower disease, Lycium barbarum root rot, Lycium barbarum mite, Lycium barbarum red mosquito, Lycium barbarum loach, Lycium barbarum rust mite, Lycium barbarum mite [1] and so on, which pose a great threat to Lycium barbarum.

In addition, there are more important pests and diseases such as Lycium barbarum moth and gray spot disease. In the comprehensive prevention and control of diseases and insect pests of Lycium barbarum, we must first clearly understand the causes and prevention methods of this disease and insect pests, and know what pesticides to spray. Lycium barbarum has strong adaptability, low requirements on soil, and all kinds of soil can grow. However, in order to achieve the goal of high quality and high yield, it is best to choose fertile fields with green sunshine, specifications, deep soil and good ventilation. However, the land types of immigrant villages and towns are complex and the soil quality has its own characteristics. However, the common characteristics are many newly opened wasteland, poor soil improvement, low maturity, soil hardening and serious salinization. In order to facilitate farming and improve soil, the Lycium barbarum garden should be planned reasonably in the future, and the field should be adjusted below 1 mu.

The cutting time of Lycium barbarum is generally from the end of March to the beginning of April in spring, and the first thing before cutting is to determine the heading field. Lycium barbarum garden chooses plots with good varieties, good growth and no pests and diseases as the courtyard where the female parent picks the ears when cutting them on hard branches. Insertion collection is also carried out in March ~ April. In the process of ear picking, we choose the hairy tree, which is about 0.5 ~ 1 cm thick and completely lignified. Use pruning shears. Cutting should be treated with root hormones-naphthylacetic acid and alcohol.
