近年来,随着龙眼经济价值的不断提高,我们垦区龙眼生产迅速发展,为改善这些农场的经济奠定了基础。但是,我们广西面临热带海洋,北部为山地高丘,受热带海洋季风影响,形成亚热带季风气候,气候温和、无霜期长、雨量充沛。既有利于作物生长,也有利于病虫滋生。龙眼大面积成片种植后,由于食料充足,必然会受到害虫的威胁。龙眼害虫的发生对龙眼树生长有着直接
In recent years, with the continuous improvement of the economic value of longan, the production of longan in our reclamation area has been rapidly developed, laying the foundation for improving the economy of these farms. However, Guangxi faces the tropical sea in the north and the mountainous hill in the north. Influenced by the tropical sea monsoon, Guangxi has a subtropical monsoon climate with mild climate, long frost-free period and abundant rainfall.

The occurrence of longan pests has a direct impact on the growth of longan trees
